摘要： A thermal power plant includes a main system in which steam generated in a boiler passes, through a steam regulating valve, a high pressure turbine, a reheater and an intercept valve, into an intermediate pressure turbine and a low pressure turbine. The thermal power plant further has a high pressure bypass system bypassing the steam regulating valve and the high pressure turbine, and an intermediate and low pressure bypass system bypassing the intercept valve and the intermediate and the low pressure tubines. Upon starting the thermal power plant, the steam generated in the boiler is delivered, through the high pressure bypass system, the reheater and the intercept valve, into the intermediate and the low pressure turbines to accelerate the turbines, and after a sinchronous steam supply, the steam is delivered into the high pressure turbine through the steam regulating valve to increase a load imposed on the power plant instead of being delivered into the high pressure bypass system. The method for starting the thermal power plant is characterized in that an opening control of the steam regulating valve is conducted when a reheated steam pressure becomes equal to or lower than a predetermined pressure level as a result of opening of the intercept valve.

摘要： In shutting down a combined power plant, a steam turbine is first shutdown while operation of a gas turbine at high load is being continued, and the steam generated in a waste heat recovery boiler is passed on to a condenser through a bypass system bypassing the steam turbine. The gas turbine is then shutdown when this condition prevails, and gland sections of the steam turbine receive a supply of gland sealing steam which has been heated by a heater to a temperature level close to that of the steam attained while the steam turbine is in operation, thereby to maintain the temperature of the metal of the steam turbine gland sections at a desired level during the time the steam and gas turbines are shutdown. In restarting the combined plant, the gas turbine is first started and then the steam turbine is started.
