Abstract
A combined cycle power generating plant has a fluidized bed furnace and a heat exchanger disposed therein, a steam turbine which is driven by steam generated in the heat exchanger and a gas turbine which is driven by combustion gas generated in the fluidized bed furnace. If the output of the whole of the plant is increased, the pressure in the fluid bed furnace is increased by supplying water into the fluidized bed furnace and then the amount of steam generated in the heat exchanger is increased by elevating the height of the fluidized bed.
