ABSTRACT:
A method of operating a combined plant made up of a gas turbine plant and a steam turbine plant utilizing the exhaust heat of the gas turbine as its power source; in which, after the steam turbine has been stopped and before it is started, the gas turbine is kept running at a low constant load for a certain period of time with the exhaust gas from the gas turbine being led partly to a by-pass duct and partly to a heat recovery boiler, during which time necessary operations to start or stop the combined plant (such as breaking the vacuum in the condenser) are performed.
