Abstract
Abstract An incinerator particularly suitable for in-house under-counter installation and use comprising a well heat-insulated structure including combustion or trash chamber and a second or afterburner chamber divided into two volumes, one being a volatiles combustion chamber containing the burner and the other being an exhaust flue, and recirculating means whereby combustion products and smoke are directed out of the combustion chamber through the burner flame for incineration. Included also is a novel air flow system for providing circulating air for combustion simultaneously with jacket cooling, means for delaying the combustion process until the afterburner has become sufficiently preheated, and means for providing automatic combustion rate control whereby rate of combustion is automatically kept constant despite large variations in the type, heat content, and size of the charge being incinerated.
