Incinerator Maximizing Combustion Efficiency

More smoke and other pollutants are released into the air during the 'start-up' and 'cool down' phases of the burn cycle

than during the 'full burn phase' when high temperatures are maintained.    Low temperature smoldering fires should be

avoided. Burn only dry feedstock and periodically add additional waste to the fire in order to maintain high burn

temperatures until all waste has been destroyed. If waste is to be open burned on the ground, the use of deep or steep-walled

'pits' should be avoided as this will prevent the necessary turbulent mixing of oxygen with the burnable gases.

Desired operating temperature should be achieved as quickly as possible when operating any burning or incineration device.  A

rapid 'start-up' can be achieved by first loosely loading dry paper, paperboard packing and untreated wood into the bottom

of the device. Dry, loosely loaded material will ignite more quickly and burn more evenly than a wet, tightly packed load.

Wet waste should only be added after  the fire is actively burning.  Overfilling the burn chamber will prevent the turbulent

mixing of burnable gases and oxygen, and should be avoided.

Modern batch feed incinerators are designed with primary and auxiliary burners to achieve and maintain the necessary high

burn temperatures. Additional waste should only be added to these incinerators once the 'cool down' phase has been

completed and it is safe to do so.
