Description of the Related Art Generally, a gas turbine has a high exhaust gas temperature (500 to 600 ° C.), so that waste heat is recovered by a waste heat boiler provided on the downstream side of the gas turbine and the steam thus obtained drives a steam turbine. Or use it alone as steam. However, when the type of gas turbine is determined, the amount of exhaust gas is determined, and the amount of steam generated in the waste heat boiler is also uniquely determined. Further, in so-called combined power generation, in which a steam turbine is driven by the steam of the waste heat boiler to generate power, the output and capacity are determined depending on the model of the gas turbine.

Further, it is conceivable to provide a duct burner between the gas turbine and the waste heat boiler to increase the heat, but since the oxygen concentration in the exhaust gas of the gas turbine is low, the range that can be raised by auxiliary combustion is:
There are limits naturally.
