燃焼器Ｃの、上部の高温部分に設けられた水管ｋにより
もたらされた蒸気によって回転し、発電を行う。Atmospheric air is compressed by the compressor a and sent to the atmospheric fluidized bed combustor 0, where coal is burned in the combustor C and heated to approximately 900° C. within the heat transfer tube d. A fluidized bed is formed in the lower part of the atmospheric pressure fluidized bed combustor C, and the coal is completely combusted. And the sky heated to almost 900 degrees Celsius! A; t enters gas turbine b, and the same turbine b
Rotate and fire. In this case, the exhaust air of gas turbine b still has a heat of approximately 4.00° C. and is therefore sent to economizer h, thereby preheating the water coming from condenser f.
