Incinerator type environmental control system

Claim 1

Incinerator apparatus of the type described for consuming waste material and the smoke products generated therefrom, comprising, in combination: a. a housing including means for providing a forced draft therethrough, a first burner chamber of relatively large volume located in a first portion of said housing and an inlet opening thereto for changing said chamber with a quantity of waste material for incineration; b. an antechamber of relatively smaller volume coupled to said first burner chamber through an exit port therein, said antechamber being adapted to receive substantially all of the smoke and exhaust gases from said incineration chamber; c. burner means generating a flame and including a second relatively smaller burner chamber coupled to said antechamber, said second burner chamber passing through said antechamber and having a plurality of intake openings therein in the region defined by said antechamber allowing all of said smoke and exhaust gases present in said antechamber to pass therethrough into said second incineration chamber whereby said smoke and exhaust gases are forced into the flame by said forced draft, said flame extending into said second burner chamber at least past said plurality of openings; d. temperature reduction means comprised of a plurality of passageways located adjacent said first burner chamber and coupled to said second burner chamber for receiving the exhaust from said second burner chamber and reducing the temperature thereof by a series of direction flow changes; e. gas scrubber means located in said housing and coupled to the output of said temperature reduction means, said scrubber means including a water bath located in the bottom thereof and having a predetermined height which is held substantially constant, an output baffle, and a plurality of water sprays located above said water bath, said exhaust from said temperature reduction means being adapted to pass beneath said water sprays and over said water bath toward and beneath said output baffle, said predetermined water level being maintained substantially constant; f. an exit flue coupled into said scrubber chamber adjacent said output baffle on the opposite side from said water sprays; and g. means for maintaining a substantially constant volumetric gas flow from said first burner chamber to said exit flue.
