摘要： A method is provided for controlling the hydrocarbon release rate during thermal processing of materials having a variable caloric content. The method includes the steps of (a) providing a first chamber for receiving successive batches of feed materials for thermal processing; (b) producing heat in the first chamber to pyrolyze the feed materials into fluid materials; (c) providing a second chamber, communicating with the first chamber, for receiving the fluid materials from the first chamber and for communicating the fluid materials to a discharge location; (d) producing heat in the second chamber to oxidize the fluid materials into discharge gases reaching the discharge location; (e) providing a jacketed vessel defining a coolant-fluid-containing channel surrounding the first and second chambers; (f) producing separate variable flows of primary and secondary air respectively into and through the first and second chambers; (g) sensing the temperatures in the first and second chambers; (h) sensing the temperature of the coolant in the jacketed vessel; (i) sensing the concentration of a preselected gas in the discharge gases. In response to the foregoing sensed parameters, controlling the primary and secondary flows of air into the first and second chambers so as to maintain the concentration of the preselected gas in the discharge gases at a preset target level, thereby generating substantially harmless discharge gases and producing substantially carbon-free residue ash. Also, in response to the sensed temperatures sensed and to the sensed concentration of the preselected gas, selectively stirring ash residue collected within the first chamber according to a predetermined pattern so as to maintain the concentration of the preselected gas in the discharge gases at a preset target level corresponding with the generation of substantially harmless discharge gases and production of substantially carbon-free residue ash.
