摘要： A steam turbine that can effectively operate with the steam at the higher temperatures, while maintaining the strength of turbine constituent components despite the high steam temperature of the steam is provided. The steam turbine includes a casing, a rotor, a plurality of turbine stages, a steam pass, a nozzle box, and a cover plate. The rotor is rotatably installed in the casing. The turbine stages are disposed in the turbine, at least one of the turbine stages including a turbine nozzle and including a moving blade that is fixed to the rotor. The steam pass includes the turbine stages. The nozzle box is placed in a space between the casing and the rotor for providing a heated steam into the steam pass. The cover plate is arranged along an outer surface of the nozzle box.

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.
