Abstract:

An air curtain incinerator and method for accelerating the burning of material in an open burning pit. The apparatus with an improved force draft air supply and manifold air distributor whereby the rate of burning, temperature and volume of air is controlled within the burning pit in such a manner that a down draft is created to the left and right of the center line thus forcing additional air into the burning pit and minimizing the amount of ash, smoke and debris which is released into the atmosphere. The apparatus is further provided with a centuri upstream of the manifold air distributor wherein an adjustable air inlet control the amount of supplemental air which is drawn into the supply conduit. The manifold air distributor includes a plurality of nozzles that extend the full length of the manifold and are directed into the burning pit at such an angle to produce a swirling effect within the pit under the air curtain to increase the resonant time long enough that all organic compounds to be destroyed with very little smoke or ash escaping.
