PURPOSE:To make constant the quantity of treated organic waste and to improve treating efficiency, by a method wherein temperature at the inside of a powder feed pipe is detected by a temperature controller, and based on the detected value, opening degrees of dampers located in a waste gas feed pipe are regulated. CONSTITUTION:In case temperature of dried waste gas flowing through a powder feed pipe 13 is, for example, below a given value, the temperature is detected by a temperature controller 27 to increase an opening degree of a damper 26, and this increases a quantity of waste gas fed in the powder feed pipe 13 through a waste gas feed pipe 25. This increases temperature of dried waste gas fed in a collector 12. Conversely, in case temperature of dried waste gas flowing through the powder feed pipe 13 is too high, temperature controllers 27 and 30 work to decrease the opening degree of the damper 26, to increase that of a damper 28, and to appropriately adjust that of a damper 29 so that temperature falls. As noted above, in case temperature of dried gas flowing out of a dryer is low, the dried waste gas may be elevated in temperature through the supply of waste gas into the powder feed pipe from an incinerator, and this permits a quantity of the treated organic waste to be made constant, and enables the improvement of treating efficiency. |
