摘要： A forced-air cooling apparatus is provided for a steam turbine which comprises an outer casing composed of upper and lower casing halves, an inner casing composed of upper and lower casing halves and disposed inside the outer casing and a rotor coaxially disposed inside the inner casing for forming a steam flow passage between the inner casing and the rotor and in which steam introduced into the steam flow passage from a steam inlet portion is impinged against blades of the rotor to impart a turning force thereto as a movable portion such as rotor with respect to a stationary portion such as an inner casing. The forced-air cooling apparatus comprises a cooling passage including a first cooling air passage formed between the inner casing and the rotor and a second cooling air passage formed between the outer casing and the inner casing, an external air inlet and outlet portion for charging external cooling air into the first and second cooling air passages during the turning operation period and discharging the cooling air after passing the first and second cooling air passages and a control unit for controlling the flow rate of the cooling air passing the first cooling air passage in response to a signal corresponding to a differential expansion detected by a differencial expansion detector between the movable portion and the stationary portion of the turbine and controlling a flow rate of the cooling air passing the second cooling air passage in response to a signal corresponding to a temperature difference between the upper and lower casing halves of the outer casing of the turbine.

摘要： A steam turbine and steam turbine plant that can utilize a relatively higher reheated steam, such as about 1300 degrees Fahrenheit or higher, is provided. A steam turbine plant includes a steam generator generating high pressure steam and reheated steam, a high pressure turbine driven by the high pressure steam generated by the steam generator, and an intermediate pressure turbine driven by the reheated steam. A steam bleed line coupled with the high pressure turbine bleeds steam from the high pressure turbine as cooling steam. The intermediate pressure turbine includes a heated steam inlet for receiving the reheated steam, and a cooling steam inlet for receiving the cooling steam. The cooling steam cools components of the intermediate pressure turbine that receive the reheated steam. A low pressure turbine is driven by steam discharged from the intermediate pressure turbine, and a condenser condenses steam discharged from the low pressure turbine into water as a condensate. A plurality of feedwater heaters heat the condensate to produce feedwater provided to the steam generator.
