Figure B-9~ EnTechU»rocess As shown in Figure B-9, 4SN is classified by combination bag breaker and gravity separator process, termed a Kinetic Streamer. Oversize materials, which are basically inorganic,are directed either to a plastics pecyder or a non-plastics etics recycling station, while the majority of waste (presumably organic) is directed to dryer to remove entrained moisture. The dryer utilizes the latent heat inherent in and the organic content of the waste to produce the heat necessary for to drive the nn gasification process. The syngas can be fired in e waste heat boiler r e subsequent electric power production. 1~2.2 Pyrolysis In pyrolysis, an organic waste (MSW) is heated without oxygen (or air), similar to the generation of coke from coal orcharcoal from wood. Both a char and a gas are generated. The gas isburned out in e gaseous phase, requiring much less oxygen than incineration. The char will usually melt at the temperatures within the pyrolysis chamber and ||| b discharged along with a black gravel-like substance, termed frit' n i the |ao� of air entering the chamber and the Advantages of this process one resulting smaller size of system components.

In full- scale demonstrations in the 1870s, it Was difficult to maintain a sealed chamber to keep air out and waste variability creates problems in maintaining consistent operation, ~~ When the pyrolysis gas is fired in a combustion chamber that is part of the system, the system is classified as an incinerator. As shown in Figure B-10" MSVV is shred into a uniform size capable of feeding into the thermal converter, or pyrolysis chamber. The pyrolysis gas generated is fired in a secondary combustion chamber, or th e ma| oxidizer, and passes through a waste heat boiler for heat recovery. Char drops out the bottom of the pyrolysis chamber for disposal or further processing for recovery of metals and other constituents. Although this system is marketed as a pyrolysis system, a combustion chamber is necessary for its operation (for destroying organics in the off-gas) and the presence of this chamber classifies the system asanincinerator. `1Souroe: Entach.
