ABSTRACT:
A regenerative bed incinerator 10 incorporates a dwell chamber 18 disposed between a pair of spaced regenerative heat exchange the beds 14A and 14B, one of which serves as a gas preheating bed and the other of which serves as a gas cooling bed. At periodic intervals, the direction of flow through the incinerator 10 is reversed so that the functions of the beds 14A and 14B is reversed. A hot gas vent duct 80 is provided for selectively bypassing a portion 7 of the hot, incinerated process exhaust gases 5 around the gas cooling bed into the gas exhaust duct 70 for venting to the atmosphere. A bypass damper 88, which is controlled by control means 86 in responsive to exit gas temperature measurements from thermocouple 90, is positioned in the hot gas vent duct 80 to control the amount of hot, incinerated process exhaust gases bypass around the gas cooling bed.
