MATERIAL CONTROLLED PROCESSING APPARATUS AND METHOD

摘要

A material processing apparatus (10) includes a coolant jacketed vessel (12) defining a first pyrolysis chamber (14) and a second oxidation chamber (16), first heating elements (18) to pyrolyze materials in the first chamber (14), second heating elements (22) to oxidize materials in the second chamber (16), an induction fan (26), airflow inlet valves (28, 30) and an air intake proportioning valve (31) for producing separate variable flows of primary and secondary air into and through the first and second chambers (14, 16), first sensors (32, 34, 36) mounted on the vessel (12) for sensing the temperatures in the first and second chambers (14, 16) and in the coolant, a second sensor (40) mounted on the vessel (12) for sensing the proportion of a predetermined gas in the discharge gases, and a control system (44) responsive to the temperatures sensed in the first and second chambers (14, 16) and the coolant and to the proportion of the predetermined gas sensed in the discharge gases for controlling the induction fan (26) and air intake proportioning valve (31).
