Abstract

PURPOSE: To utilize the exhaust gas of high temperature effectively by making the combustion exhaust gas exchange heat with cooling water, while the concentration of the oxygen of the gas being kept low, and by cooling the gas down to a specified temperature on the occasion that the fine coal dust is transferred through the pipe line by using the combustion exhaust gas.
CONSTITUTION: The combustion exhaust gas of high temperature is cooled down to the temperature of 400W600°C by a heat exchanger 3, is turned to be the gas for drying in a hot-air producing device 1, and then is supplied to a drier 7. By the steam obtained from the heat exchanger 3, a turbine 4 is driven and the electricity is generated by a generator 5 and is supplied to a crucher 6, a pump for cooler 11 and a compressor 12. A transferring device 13 of the pneumatic pipe line receives the fine coal dust cut out from the bottom part of a silo 8 and conveyed by a conveyor 14, through the intermediary of a bunker 15 and a feeder 16 which receive the coal dust, and transfers the coal dust to an aimed place through the pipe line l9 by means of the gas from the compressor 12 through the gas pipe line l7 and l8.
