PURPOSE:To reduce total cost for use in places of business by controlling the temperature of a combustor of a gas turbine by injection steam from a waste heat boiler and steam from a steam turbine generator. CONSTITUTION:A combustor 3 produces hot gas for use in driving a gas turbine generator 6. Steam is produced by allowing hot exhaust gas exhausted from the gas turbine generator 6 to pass through a waste heat boiler 7, and the combustor 3 is controlled in its temperature by produced injection steam. With insufficient injection steam from the waste heat boiler 7, the combustor 3 is controlled in its temperature by steam from a steam turbine generator 8. Thus, total cost thereof for use in places of business can be reduced. |
