Burner apparatus for simultaneously incinerating liquid, dry gas and wet gas streams

An improved burner apparatus for simultaneously incinerating liquid, dry gas and wet gas streams comprising:

• a housing having a forward firing wall, a back wall spaced rearwardly from said forward firing wall, and a side wall extending forwardly to said firing wall and rearwardly to said back wall and forming an enclosed plenum chamber, said housing further including a first baffle having a forward end attached to said firing wall and having a rearward end adjacent said back wall, said first baffle being disposed within said side wall so that a primary air plenum is defined by and between said first baffle and said side wall of said housing, there being an air inlet into said primary air plenum;
• and a perforated second baffle having a forward end attached to said firing wall and having a rearward end attached to said back wall, said second baffle being disposed within said first baffle so that a secondary plenum is defined by and between said first baffle and said second baffle and so that a tertiary plenum is defined by and within said second baffle;
• and said firing wall including a plurality of air passages in communication with said secondary and tertiary plenums but not with said primary plenum so that air flows through said air passages only from said secondary and tertiary plenums;
• a centrally positioned elongated gas burner tube sealingly connected through said back wall, extending longitudinally through said housing within said tertiary plenum and through said firing wall, the rearward end of said gas burner tube having a wet gas and/or dry gas inlet connection attached thereto and the forward end of said tube terminating in a gas burner nozzle positioned adjacent said firing wall;
• means for heating gas flowing through said gas burner tube and attached thereto;
• at least one liquid burner tube positioned adjacent said gas burner tube within said tertiary plenum and further sealingly connected through said back wall, extending longitudinally through said housing and extending through said firing wall;
• means for atomizing a liquid issuing from said liquid burner tube and distributing the atomized liquid produced, and further said liquid burner tube including a liquid stream inlet connection disposed in said liquid burner tube, whereby atomized liquid is distributed from a forward end of said liquid burner tube at a position adjacent said firing wall;
• and
• means for igniting and continuously combusting fuel gas attached to said firing wall and positioned adjacent said gas burner nozzle means and the forward end of said liquid burner tube.
