Combustion device for burning waste gases containing combustible and noxious matters

A combustion system for burning combustible and noxious waste gases comprising:

• a housing having two ends and a longitudinal axis;
• inlet means at one end of said housing;
• outlet means at the same end of said housing as said inlet means
• partition means in said housing for longitudinally dividing said housing into a plurality of compartments;
• a temperature adjusting chamber at the opposite end of said housing from said inlet and outlet means;
• a plurality of fixed, highly thermally conductive metal regenerative means positioned in said plurality of compartments, the waste gases burning in said regenerative means, said regenerative means each comprising a plurality of longitudinally with respect to said axis extending corrugated stainless steel plates,
• said corrugations being arranged with the corrugations of adjacent plates intersecting at right angles with each other defining meandering passages for the flow of waste gases therebetween, said corrugations extending at an angle greater than zero with respect to said axis;
• temperature sensing means in said chamber;
• auxiliary burner means located in said chamber for adding heat only when the quantity of heat is insufficient for efficient combustion of said waste gases, said auxiliary burner means being operatively associated with said temperature sensing means;
• means for discharging combusting gases from said chamber when the temperature in said chamber exceeds a predetermined maximum, said means for discharging being operatively associated with said temperature sensing means;
• rotary valve means in said housing operatively connecting said inlet and outlet means to said housing for directing the flow of waste gases serially through said compartment;
• and
• means for rotating said rotary valve means;
• the flow entering at least one compartment, passing through said chamber and exiting through at least one other compartment, said rotary valve means rotating and sequentially valving the flow through said compartments.
