Multiple unit material processing apparatus

A material processing apparatus, comprising:

• (a) a casing having outer and inner spaced walls forming an airtight vessel inside of said inner walls and a channel between said outer and inner walls surrounding said vessel for containing a flow of coolant fluid;
• (b) said vessel containing a first chamber having an inlet and a second chamber connected in communication with said first chamber and having an outlet, said first chamber for receiving and pyrolyzing materials therein, said second chamber for oxidizing pyrolyzed materials therein and discharging pyrolyzed and oxidized materials therefrom;
• (c) said casing being defined by separate first and second units spaced from one another and means extending between and interconnecting said spaced first and second units for defining a flow communicating passage between said first and second units;
• (d) said first chamber of said vessel for receiving and pyrolyzing materials being disposed in said first unit, said second chamber of said vessel having primary and secondary sections for oxidizing materials in two successive stages, said primary section of said first chamber being disposed in said first unit between said first chamber and said flow communicating passage defining means, said secondary section of said second chamber being disposed in said second unit;
• (e) means mounted to said vessel and communicating with said first and second chambers for producing primary and secondary one-way flows of air into and through said first and second chambers and from said first unit through said flow communicating passage defining means and into said second unit;
• and
• (f) means coupled to said primary and secondary one-way air flow producing means for controlling the operation thereof to proportion the respective amounts of primary and secondary one-way air flows into and through said first and second chambers and from said first unit to said second unit through said flow communication passage defining means.
