The air introduced into the heat exchanger tubes 5 of the fluidized bed combustor 4 is heated by the combustion of coal passing through the combustion chamber 8, and is heated to 9'00°C. It is sent to the reheater 9. In the reheater 9, coal is burned in the combustion chamber 11 in advance, and the temperature is approximately 1.500°C.
A large amount of combustion gas is generated, and this combustion gas rises through a ceramic tube.
