PRINCIPLE OF AIR CURTAIN INCINERATION
Air curtain incinerators are designed primarily as a pollution control device. Using a
Diesel engine driven fan, these machines generate a curtain of air with a very particu-
lar mass flow and velocity. This curtain of air acts as a trap over the top of an earthen
trench or thermo-ceramic lined pit. The wood debris is dumped into the trench or pit
and then ignited (usually with a propane torch or with a small amount of Diesel fuel)
just as you would light any other pile of wood you intended to burn. Once the fire has
gained strength the air curtain is turned on. The air curtain traps most of the smoke
particles and causes them to re-burn under the air curtain where the temperatures ex-
ceed 1,800º F. These machines do not inject any fuels into the fire, the fire is sustained
only by adding more wood debris. The air from the air curtain is not heated. The only
fuel used in the continuous operation is that of the Diesel engine driven fan.
1. Manifold and nozzles that create the air curtain over the refractory lined pit.
2. Wall of earthen pit.
3. Material to be burned.
4. High velocity "air curtain" over fire.
5. Continued air flow over-oxygenates fire keeping temperatures high.
