By making the pipe a vertical type, there is no possibility of the pipe being curved, a long object can be used, and the throughput of one pipe can be increased. Depending on the number of tubes, the throughput can be as wide as 10T / day-1000T / day. The decomposed gas is released from the nozzle into the furnace and burned to maintain the tube at 400 ° C. or higher, thereby promoting the thermal decomposition reaction. Generated carbides can be temporarily stored or super-R
It is also possible to burn and gasify as DF and recover energy. The odor generated in the waste treatment sends the air containing the odor into the furnace and deodorizes it as combustion air.
