Four representative garbage incinerator

wholeWaste incineration technology sprouted in the late 1800s. Since the 20th century, with the development of greatly improved and incineration of municipal waste production, waste incineration has become in many countries to develop waste treatment technology.

Garbage incinerator waste incineration is the core technology. Early incinerators by coal-fired boiler manufacturing factory, does not apply to municipal solid waste combustion. With the development of waste incineration process, the waste incinerator technology has matured, the world of various types of waste incinerators reached over 200 kinds, but a wide range of applications, with typical incinerator technology there are four main categories, namely mechanical furnace row incinerator technology, fluidized bed incinerator technology, rotary kiln incinerator technology and pyrolysis and gasification incinerator technologies.

At present, China's incineration plant construction appropriate to adopt more mature mechanical grate incinerator. In a perfect situation pretreatment system it can also be used a fluidized bed incinerator technology. Rotary and pyrolysis and gasification incinerator less technical applications, can be used as the first two technologies complement.
Mechanical grate incinerator technology
Mechanical grate incinerator garbage incinerator type of early development, through long-term development, the technology has been maturing, high reliability, is currently leading products on the market garbage incinerator.
Mechanical grate incinerator grate structure and movement based on different ways of diverse types, but roughly the same combustion principle, refuse on the grate were stratified combustion, after drying, combustion, post-burn ash discharge of the furnace. Grate will adopt a variety of different ways to make the material layer of garbage continue to be loose and make full contact with the air of garbage, so as to achieve ideal combustion. Garbage grate combustion air is fed from the bottom, depending on the garbage calorific value and moisture into the air grate may be hot or cold. At present, in the form of mechanical grate incinerators include cis push grate furnace, reverse push grate, reciprocating grate furnace and turning rolling grate.
Low mechanical grate incinerator for garbage pretreatment requirements, the garbage calorific value of wide application, easy operation and maintenance. In addition, a single mechanical furnace processing capacity is large, especially for large-scale garbage treatment.
But the mechanical grate incinerator complex mechanical structure, grate material requirements and processing high precision, high cost and maintenance costs.
Fluidized bed incinerator technology
Fluidized bed incinerator technology is a mature technology, which mainly depends on the material of the fluidized bed furnace temperature heat capacity, strong mixing and heat transfer effect, so that rapid warming garbage into the furnace of fire, the formation of the entire bed within the homogeneous combustion. Fluidized bed incinerator technology is the use of fluidized garbage incineration in the furnace a large number of quartz sand as a heat carrier, garbage burning in the furnace suspended.
Fluidized bed incinerator for garbage, there are strict pre-requirements, must be broken into smaller particle size garbage before being burned into the furnace, resulting in high energy consumption and preprocessing strictly odor control requirements. Fluidized bed incinerator waste and bed material in a fluidized state, badly worn, maintenance more frequently, annual operating time than mechanical grate short.
In addition, due to lower current domestic garbage calorific value, difficult individual combustion, co-firing coal need. Advantages of fluidized bed incinerator, due to garbage after crushing to burn fast burn rate, start and stop the furnace and convenient, the general discharge of unburned material released outside were about 1%, is the lowest in several ways of. In addition, the fluidized bed incinerator structure is relatively simple, low cost.
Rotary kiln incinerator technology
Rotary kiln incinerator furnace or water to use firebrick fireplace wall cylindrical roller. It is rotated by the furnace as a whole, so that the garbage uniformly mixed and inclined along the inclination angle end state of the mobile churn. In order to achieve complete incineration of garbage, generally equipped with secondary combustion chamber. When burning garbage, supplied by the upper rotary kiln, rotary drum slowly, so that the garbage constantly flipped to move gradually dry garbage, burn, burn, and then discharged to the slagging device.
Adjust the speed of the rotary kiln, it can affect the garbage in the kiln residence time, and to exert a strong mechanical collision of garbage in hot air and excess oxygen, combustible materials and corruption can be very low slag content. The main disadvantage of this technique is not the amount of waste, fly ash handling difficult, difficult to control the combustion in the current application is less waste incineration.
Pyrolysis and gasification incinerator technology
Pyrolysis and gasification incinerator technology was first used in North America to get this incinerator in Canada called the CAO (Controlled Air Oxidation), it means that the control of air oxidation, in developed countries there are a small number of applications.
Pyrolysis and gasification incinerator has two combustion chambers, two of the combustion chamber by controlling the supply air flow and temperature to achieve complete combustion and pyrolysis and gasification. In the first combustion air supply amount is a 70% -80% of the theoretical amount of air, the temperature control at 600-800 ° C, only allow some solid waste combustion, relying on its solid waste combustion heat so the rest is broken down into a combustible gas; the second fuel room for air volume of 130% -200% of the required amount, the temperature control at about 1000 ° C, the residence time of two seconds, so that the combustible gas combustion, toxic gases completely decomposed, achieve sound.
Pyrolysis and gasification incinerator can effectively inhibit the generation of dioxin, the disadvantage is smaller waste disposal, system complexity, higher operating costs.

Volcano can become garbage incinerator it?

The idea is good . There toss volcano every day, it appears to be an ideal natural elimination of garbage incinerator. However, I know you want to, but that there is kind of the center of the crater lake of lava lovely. Like some of the shield volcano in Hawaii, they will spray lava slowly to the ground, burning garbage seems very appropriate.

But in fact most of the volcanoes on Earth is called stratovolcanoes, they occasionally have lava flows, but once the heat is too high inside the volcano, the lava "exploding", but said that the explosion on the explosion. Take one of the Kilauea volcano, the 20th century it erupted 45 times, still often eruption (Figures are it erupted April 23, 2015 in, HVO / USGS). If you're close to bring garbage thrown into lava, volcanic ash in the distance, just a splash of lava and toxic gases can make you die of.
We want to deal with waste is not insignificant. Said generation American, four pounds per person per day and a half of garbage a year is 250 million tons. If we want to deal with volcanic waste, we need to first lock on the appropriate active volcano, put the garbage there. Few people live near an active volcano, delivered to the garbage will spend a lot of time, money and fuel. You always have to worry about people throwing trash or garbage truck safety.
You have to know that when touched to a large number of normal garbage magma may explode instantly. In 2002, researchers in Ethiopia will be a 30-kilogram bag of garbage thrown into the crater, the result was shocking to see the spectacular explosion. And that package is only equivalent to the United States four garbage home half of the week garbage "yield." Scientists also observed scene rockfall fall when the lava lake in Hawaii, lava spilled 85 meters of altitude, lava splashing into distant fence and scientific network cameras. So go down garbage, a little too risky.
Not to mention that all the gas you when burning garbage in the volcano, the generated directly into the atmosphere, resulting in a lot of air pollution. And today's formal regulatory incinerator has systems to ensure that garbage incineration smoke treated before entering the atmosphere. System to prevent the spread of major pollutants is ozone, carbon monoxide and sulfur dioxide.
Human civilization can not be manufactured pieces of debris are thrown into the volcano, there is another reason. That some of the more specialized waste, such as medical waste or nuclear waste, they tend to be particularly dangerous thing. The volcanic lava in a temperature of approximately 700 to 1250 degrees Celsius, which is of course very hot, but the temperature is not enough.
So, with volcanoes act as a garbage incinerator is probably slightly wrong. But still this sentence: a good idea. Please continue to think, to act as a viable method envisaged transfer of volcanic waste incinerator.QQ图片20151223143317

burning 150 kg of waste incinerator

In a bid to bring a partial relief from the mounting waste disposal issues, a new incinerator will begin functioning at the Kozhikode Medical College soon. Authorities say that the new incinerator will become operational by the first week of August.

The incinerator has been installed using the fund from the Hospital Development Society (HDS).

HDS member Saleem Madavoor told 'City Express' that the society has allotted `15 lakh towards the expenses that will be acquired for the installation works. Kerala Small Industries Development Corporation Limited(SIDCO), a state government undertaking has been entrusted with the works.

An official of the medical college said that an expert team, deputed by SIDCO, has visited the medical college to review the primary arrangements.

The work order has been given to SIDCO and an agreement was signed between the medical college authorities and SIDCO officials three months back.

The medical college official added that the works of the incinerator are completed and installation works will start within few days.  When the new incinerator begins operating, the waste disposal issues will be partially addressed. The incinerator which has a capacity of burning 150 kg of waste, will dispose of the residue generated from the medical college hospital.

Meanwhile, the medical college will continue to grapple with the waste being generated from the Institute of Maternal and Child Health (IMCH) and Super Specialty block as the incinerator for these blocks, which have been proposed at a cost of `63.5 lakh by the state government still remains on papers. If the incinerator becomes a reality around 5,000 kg of waste can be disposed everyday.

Moving Forward on Open Waste Burning

The permit that allows the Radford Army Ammunitions Plant to burn hazardous waste from firearms outdoors is up for renewal. Community activists see an opportunity to address environmental and health concerns about the open burning – and state regulators see a chance to explore new technology to solve an old problem.
Just a handful of people turned at the Blacksburg Public Library on a recent afternoon for a meeting of the Environmental Patriots of the New River Valley.

"Is there anything we could post to get more people involved? Yes, petitions, a letter campaign... When the EPA was pushed to the wall in Louisiana, they said 'Uncle.' So, we want you Senator Kaine and you Senator Warner to do just what Senator Vitter did in Louisiana and write to the EPA and ask them, 'How is this not a violation of the clean air act?'"

Devawn Oberlender is looking to take a pager from the book of a far away town, where citizen protestors succeeded in stopping outdoor burning explosives of arms and weapons waste at the Louisiana Army Ammunition Plant.

"The opportunity that we have right now only comes up very ten years, because the permit is good for ten years, so what we need to replicate is what they did in north western Louisiana at Camp Minden.

There they formed a "Stop the Burn" movement that ultimately brought together elected officials, state and local regulators and the army for a plan to give up open burning and use a modern indoor incinerator to dispose of the toxic materials. Now, with the open burning permit at the Radford Arsenal up for renewal, the Virginia Department of Environmental Quality is exploring that idea for the first time. William Hayden is spokesman for DEQ in Virginia.

"We have not reached any conclusions yet but that is something that would be looked at as we move forward. We have asked the Arsenal to come up with alternatives to open burning and we do expect to have some options that go beyond the idea of just burning it the open."

Brian Salvatore is a professor of Organic chemistry at Louisiana State University who argued for using contained incineration.

"This is what we fought for here at camp Minden. And yes it added another 15million dollars and almost doubled the cost of the contract but this was something that, the EPA was willing to go to bat for us for. So I'm glad that the people in the EPA and in the state worked together here and they worked with the Army as well to find the additional money. And we're quite satisfied here that this alternative -- which, in the beginning of this we didn't know all the details of what these modern incinerators can do. We're quite confident here that this is going to do the job and the amount of material that's going to be released total will be on the order of tens of grams as opposed to tons of these emissions."

A spokesman for the Environmental Protection Agency's Region 3, which includes Virginia, said it could not comment on the possibility of incinerators like that being adopted at the Radford site, but a spokesperson for BAE Systems, the contractor in charge of the arsenal, confirmed it is "looking for viable alternatives to its current methods of waste disposal."

The department of Environmental Quality has asked BAE to conduct an environmental impact study on its current open burning practice. William Hayden says it's the first time DEQ has asked for one.

"Because we're getting in to an issue that has generated a lot of public interest in the Radford area we knew that the more information we had, the better. People from the public have been asking for us information; they've been asking Radford (the arsenal) for information."

And one of them is Oberlender who says, "We've been burning waste out there, open burning it since 1941. You know, it's not going away."

And neither are the environmental patriots of the new river valley. Taking another page from the story of Camp Minden Louisiana's successful effort to get its outdoor burning moved indoors. They're scheduling meetings with state and federal officials to keep the pressure on. The first is this Friday with U.S. Representative Morgan Griffith who sits on the Committee on Energy and Commerce, which has oversight of the EPA. The group is looking to make a national issue out of one that has for so long been so local and one of the few places where open burning of hazardous waste from explosives is still allowed.

CPASA success: Up in smoke

CPASA (Community Partners Against Substance Abuse) Director Dawn Conerton was thrilled to announce the new purchase.

She confirmed the organization was able to use money from its reserves to help with the purchase. However, CPASA is still looking for donations to help make up the cost and also to help with the upkeep of equipment.

The incinerator is located at the Princeton Police Department. A fence and a shelter still needs to be built around the incinerator before it's used.

As previously reported in the BCR and the Putnam County Record, the state made the decision to no longer dispose of prescription drugs, forcing CPASA to look into the purchase of an incinerator to continue its program, which allows residents to dispose of their unused prescription medications in a safe manner.

The cost of the incinerator came to around $10,000.

Since CPASA's formation in July 2010, it has worked to keep unused prescription drugs off the street. Since September 2014, the program has collected and disposed of about 7,235 pounds of drugs.

Conerton explained how CPASA has worked hard to get the incinerator to help maintain the P2D2 program.

She said with the incinerator, CPASA will be able to continue educating the public about the safe way to dispose of drugs and remind them not to flush medication into the water supply.

"It hurts the water supply, and we also are getting them out of cupboards to prevent them from getting into the wrong hands," she said. "We now have a way to actually dispose of them completely."

With the incinerator, CPASA now plans to host more collection days to help get rid of even more unused medications.

Princeton Police Chief Tom Root was also thrilled with the arrival of the incinerator. He explained the incinerator can get up to 2,000 degrees Fahrenheit and takes about 20 minutes to burn down the material. The drugs are burned down to a fine powder, which is bagged and taken to the landfill.

The incinerator arrived at about the right time, as Root said there is currently about 1,500 pounds of pills to dispose of from the Bureau and Putnam counties area.

Root said CPASA plans to charge a fee to communities who don't provide a donation for the incinerator. The fees will help maintain the incinerator and help keep up with the purchase of diesel fuel.

CPASA is still looking for donations to help make up for the cost of the incinerator and to help continue the work CPASA does throughout the year.

"CPASA appreciates all the donations. We would never have believed in such a short amount of time this would be a reality," Conerton said. "This community is so awesome with their support and knowing how important it was to help. It's widespread and something that's going to help everyone."

CPASA is also hosting a fundraiser on Saturday, Aug. 1, from 11 a.m. to 6 p.m. in Zearing Park. More details to come on the event.

Efficient stove technology eases N. Kenya's medical waste problem

WAMBA, Kenya, June 30 (Thomson Reuters Foundation) - Poor weather, security threats and bad roads have made disposing of the Wamba district hospital's medical waste a challenge.

The nearest incinerator is about 200 kilometres (125 miles) away and "travelling was not possible during heavy rains because connecting roads were cut off by floods," said Stephen Lesrumat, a medic at the hospital.

But now the north-central Kenyan hospital has a solution to its problems, and a way of cutting climate changing emissions and deforestation: A high-efficiency medical waste incinerator that uses just a fifth the fuel of a traditional incinerator.

The wood burner, which takes advantage of powerful winds in the region to drive the flames, borrows technology from fuel-efficient stoves. It can safely eliminate waste produced by the Wamba hospital and by 22 other health centres in Samburu County, said Lesrumat and Ibrahim Lokomoi, the facility's engineer.

"It has reduced the burden of travelling outside the county to get rid of medical waste," Lesrumat said, sparing hospitals a potentially dangerous build-up of medical waste during periods when roads are impassible.

During previous flood periods, when hospital waste could not be transported, "I was worried because the waste is toxic," Lesrumat said. "It could cause health and environment damage if it accidentally spilled into the community."

Run-ins with al Shabaab militants can also be a hazard for some medical workers in Kenya driving long distances in their jobs, medics said.

"Northern Kenya is very expansive and has so many challenges that the government struggles to deliver services," said Onyango Okoth the assistant commissioner of Samburu County.

Now the Wamba incinerator handles between 5 and 20 kilograms of medical waste a day.

As the burner operates, a young worker clad in protective clothing flips open the lid of the chamber to monitor the process of incineration.

Seeing the last batch of waste is almost eliminated, he reaches for a barrel containing an assortment of used rubber gloves, syringes and polythene waste, pours in some of the waste, mixes it with a forked rod and then replaces the lid to allow the incineration to continue.

The Centers for Diseases Control in Kenya estimates that every patient admitted in a hospital generates at least 0.5 kilograms of medical waste. The National Environment Management Authority requires every health facility to dispose of medical waste through incineration.


The next step, Kenyan clean energy experts say, may be to begin incinerating waste using even more sustainable sources of energy, such as solar power.

"Kenya is investing heavily in alternative energy sources," said Johnson Kimani of the Kenya Climate Change Working Group. "Solar and biogas should be factored into medical waste incineration if the government is committed to its pledge of achieving a green economy."

James Lebasha, of the International Medical Corps, which helped construct the Wamba incinerator, said the burner may be just the first for the region.

"We hope to build more units in morthern Kenya to enable communities access this service," he said.

SWRHA chairman: Delay in payment causes medical waste back-up

Chairman of the South West Regional Health Authority (SWRHA) Dr Lackram Bodoe said a back-up of medical waste at the San Fernando General Hospital had to do with a delay in payment to a contractor and not the malfunctioning of the incinerator.

Responding to complaints about the dangers posed by the accumulated medical waste, which included amputated limbs, needles, and bloodstained items, Bodoe assured that the $9 million incinerator installed last year was functioning well.

He said it was allowed to accumulate because daily paid workers refused to work on Tuesday.

Speaking with members of the media at SWRHA's symposium on leadership at the Southern Academy of Performing Arts on Wednesday, Bodoe said:

"I want to give the assurance that the incinerator itself is working well.

"It is a new incinerator that was installed last year and the issue had to do with a contractor who was supposed to remove the garbage and there was a delay of funding and that is what created a temporary situation yesterday."

Asked how soon the situation will be rectified, he said: "I have just been given the assurance by the CEO that the matter is being dealt with as we speak, so I expect by the end of the day it will be sorted out."

In addition, Bodoe said the SWRHA was also considering introducing a new type of technology, called the radio wave technology for incineration, which was much more atmosphere friendly.

However, a Public Service Association representative, who wished to remain anonymous, said the incinerator had been breaking down on a regular basis since it was installed last year and was not working at this time.

"They even had to revert to the old incinerator and that is unsafe and unhealthy to people operating that incinerator. Since last week Thursday the incinerator (new one) is down," he added.

He said workers took the action on Tuesday because since last week they were assured that the garbage problem would have been sorted out.

Mine Spews Toxic Fumes: NWT Air Regulations Not in Place

Snap Lake Mine, 220 kilometres northeast of Yellowknife, where elevated levels of dioxins and furans were pumped into the air. | Photo Fire Prevention Services

Last July, two incinerators at De Beers' Snap Lake Mine were belching out clouds of black smoke, one sending an average of 65 times the accepted national limit of cancer-causing toxins into the air.

The hugely elevated levels of dioxins and furans — released when plastic is burned or garbage is not fully incinerated — were recorded during a four-day "stack test." According to the World Health Organization, "dioxins are highly toxic and can cause reproductive and developmental problems, damage the immune system, interfere with hormones and also cause cancer." The Canada-Wide Standards recommends emission levels for dioxins and furans not exceed 80 picograms per cubic metre. The company contracted to do the testing at Snap Lake found that one of the mine's incinerators was emitting 6.5 times the acceptable limit, while the other incinerator was emitting a whopping 65 times the acceptable limit (5,220 picograms per cubic metre on average, as



It's unclear how long this was going on for, though the report noted the problem was clearly visible: "Black opaque smoke was noted for all tests early in the incineration cycle."

De Beers did not respond to EDGE's request for an interview by the time of publication. However, according to a letter from De Beers' Environment and Permitting Superintendent, Alexandra Hood, sent to the GNWT and Environment Canada in January, the root cause of the problem was "not following standardized work practices," and running the incinerators, which were only installed in 2013, at too low a temperature.

Since flunking the test, De Beers has retrained staff, rewritten operating procedures and brought in new policy to shut down the incinerators if they're not meeting the correct temperatures (if it's safe to do so), according to Hood's letter. An inspection of the Snap Lake incinerators by a GNWT Lands Officer in March suggests De Beers has ameliorated the problem, at least in part: "No concerns were noted during this inspection," it states, and "the west incinerator which was burning waste at the time of inspection was emitting clear exhaust gas with no black smoke coming from the stack."

Whether or not sufficient steps have been taken, however, won't be known for years: the next stack test is not scheduled until 2019, according to a source close to the issue wishing to remain anonymous.

No GNWT regulation

The fact that, for an undetermined period of time around July 2014, the Snap Lake incinerators were pumping out unacceptable levels of toxic emissions is troublesome in itself. But it points to a much larger problem in the territory; the GNWT does not regulate emissions, require companies to meet the CWS, or mandate stack testing. (The Mackenzie Valley Land and Water Board, likewise, does not regulate air emissions.)

At several points in her letter, Hood notes the lack of regulation, claiming De Beers "will conform with any regulatory requirements regarding incinerator stack testing once enabling legislation is developed and approved in the NWT."

Without legislation in place, there is nothing to force De Beers or other groups using incinerators (i.e. every single mine in the territory), to keep their emissions at a safe level or undertake stack testing on a regular basis. Each mine has an Air Quality and Emissions Management Plan as part of its environmental agreement, but these plans only dictate reporting requirements, not actual emission targets. And while Hood claims "deficiencies, as measured against the Canada Wide Standards, will be managed through adaptive management and continuous improvement by De Beers," there's little government oversight of this "continuous improvement" and no fines or other mechanisms to force polluting companies to remedy their ways.

This problem has been going on for years. According to a Canadian Press report from 2011, the scientific journal Integrated Environmental Assessment and Management found sediments in a lake near the Ekati Mine that had levels of dioxins and furans 10 times higher than those collected from an uncontaminated lake. The same report cited a 2007 study commissioned by Environment Canada which suggested "extensive, uncontrolled burning of wastes could result in substantial accumulations of dioxins and furans in the local ecosystem, some of which will persist for some 8½ years at levels approaching those considered to be of toxicological concern."

"In most cases we're below the level that health agencies would (watch) for…" the study continues, "but we're getting there. And if you have more incinerators and more burning, you may well exceed those levels."

The GNWT's Department of Environment and Natural resources did not return EDGE's request for comment on the lack of regulation.

Why no regulation?

Back in 2001, the GNWT did sign on to the Canada-Wide Standards of dioxins and furans with all other provinces and territories (except Quebec) as part of a national Accord on Environmental Harmonization.

The document says: "Parties are required to take measures to reduce total releases from anthropogenic sources of dioxins, furans… with the goal of their continuing minimization and where feasible (technically and socio-economically), ultimate elimination." However, it adds, "each jurisdiction will determine the exact means of ensuring compliance" – basically defanging the document by letting provinces and territories renege on their commitment with no repercussions.

Other jurisdictions have taken proactive steps, bringing in legislation to regulate emissions in line with the CWS. The GNWT has not. They did bring in guidelines for managing biomedical waste in 2005, but they have been unwilling to regulate incinerators at mine sites. Their reason? The "waste incinerators operating at remote industrial sites within the NWT… are located on federal crown land and are not regulated by the Government of the Northwest Territories," says a report from 2009.

This may have been true in 2009, but post-devolution it's no longer the case. Since April of last year, the mines are on land managed by the GNWT, yet there have been no moves from legislators to start regulating toxic emissions from mine or other industrial incinerators. The last time the issue was discussed in the legislative assembly in 2011, Weledeh MLA Bob Bromley said a "loophole in environmental rules is allowing a growing number of unregulated waste incinerators to release extremely toxic chemicals into the land and water." He suggested, "when we take on new powers, we must be ready to move with new law."

Devolution has come, and incinerators are still operating in an unregulated environment. With all the talk of fracking and opening up new mining projects in the territory, it's now time, more than ever, for the GNWT to get its act together.

New Courtice incinerator hits further delays

CLARINGTON -- Clarington's new energy-from-waste facility will be delayed a second time because the boilers aren't operating properly and the ongoing startup period could cost Durham Region an extra $1 million.

"I'd rather see it delayed and done right than rushed," said Clarington Mayor Adrian Foster.

The Durham York Energy Centre facility, located in Courtice, was scheduled to be fully operational on Dec. 14, 2014. Now the Durham York Energy Centre is not expected to be in full working order until the last quarter of 2015.

The major systems of the EFW facility have been tested. The boiler temperature is high enough for the combustion process but the steam temperature isn't high enough, and officials aren't sure what the problem is, says Durham's works commissioner, Cliff Curtis.

The steam temperature has to be high enough to drive the turbine-generator. If the steam is too cool it can damage the turbine.

"It's like running a car without oil," said Mr. Curtis.

Covanta, the company building and operating the facility for Durham and York regions, has taken the boilers down for modifications, according to Mr. Curtis. It's expected to take three weeks for the repairs and modifications. Then there will be a four-week demonstration period, followed by a 30-day acceptance test.

"We're not getting the temperature we expected out of the boiler. Once we get the temperature up, I think everything will fall into place," said Mr. Curtis. "It's Covanta's problem to deliver us the product that performs the way they said, so they're going to take the time they need."

The delay means added consultant costs for construction management, legal advice and baseline ambient air monitoring. A Durham Region works report said Durham's share of the additional costs is $1 million, which can be provided from a temporary draw on the solid waste management reserve fund.

"What's the final cost going to look like?" said Clarington Regional Councillor Joe Neal, who added he still has concerns about the emissions meeting the Ministry of Environment rules. "There are clearly issues with getting it started out."

Since Jan. 16, Durham has been charging Covanta a $10,000-a-day late fee for every day the EFW facility is not fully operational. The invoice has been sent to Covanta, but it hasn't been paid yet, according to Mr. Curtis.

In mid-February, the incinerator began burning its first haul of curbside garbage. It was part of a testing phase before the facility opens fully.

Durham cancelled landfill contracts and began sending garbage to the Courtice facility. Some garbage was burned at the EFW plant during the test phase, without producing power to the grid. Covanta has also been sending the trash to its incinerator in New York state, or landfills in the Niagara region.

Until the EFW facility is up and running, the Region only pays Covanta half price of the agreed upon per-tonne fee. However, Durham isn't making any money until the plant is fully operational and selling power back onto the grid.

"We're still on budget. I'd rather be getting electricity sales on the grid," said Mr. Curtis.

The plant construction is coming in slightly under budget, according to the works commissioner.

There are a few loose ends that could end up costing Durham Region more money. There is still disagreement with former property owners on the value of the land expropriated for the facility, and a ruling is not expected until fall of next year. The final cost for the utility construction and connection costs is expected in coming months. The baseline ambient air monitoring runs until the EFW facility is operational, so the delay in opening means an ongoing monitoring cost.

"There's some minor cost over-runs on some of the smaller items but generally we're financially on track to bring this in on budget and we look forward to having it online by the end of the year," said Mr. Curtis.


The Durham York Energy Centre is designed to process up to 140,000 tonnes of waste each year, and generate 17.5 gross megawatts of renewable energy -- enough to power between 10,000 and 12,000 homes. A key part of the economic case for the energy-from-waste facility depends on it generating electrical power revenue.

Double Combustion Chamber Incinerators

Incinerator Introduction

Primary combustion chamber temperature # 850°C with no cold spots

Secondary combustion chamber: Shall be constructed with an exterior casing (reinforced to withstand internal pressures without deflection or damage to the refractory or other components) and provided with refractory lining and insulation

Secondary combustion chamber temperature 1100°C or higher

Secondary combustion chamber residence time # 2 seconds after the last injection of air in the secondary chamber

Primary and secondary burners: Separate electrically spark-ignited primary burners and secondary burners with automatic control shall be used to achieve the specified temperature requirements in the primary and secondary chambers. The flames of the primary and secondary burners shall not impinge on the incinerator walls or floor.

Energy source for burners Diesel fuel eil

Air supply: Air supply in the primary and secondary chamber should be regulated between 30%-80% and 170%- 120% of stoichiometric amount respectively. Suitable flow measurement devices shall be provided on the primary and secondary air ducting. The combustion air shall be supplied through a separate forced draft fan after accounting for the air supplied through burners

lnsulation: lnsulation to be used for masonry, reinforced concrete, or non-combustible material shall prevent damage to the foundation from excessive heat and shall be of a thickness to limit the outer casing to a maximum temperature of 66°C in an ambient temperature of 21°C when the incinerator is operating at full capacity.

Refractory: Refractory shall be #super duty# and heat-resistant to a minimum of 1100°C in the primary chamber and 1250°C in the secondary chamber. Refractory shall also be abrasion resistant in the prlmary chamber, constructed of plastic or castable type refractory, designed to prevent bulging and destruction due to heat stress, capable of supporting more than twice the hourly burning rate and preventing leakage of fluids, and with a minimum thickness of 11O mm for walls and hearths
