专利汇可以提供Turbine bypass system专利检索,专利查询,专利分析的服务。并且PURPOSE:To enable to perform stable turbine bypass operation without changing the design of a deaerator, by utilizing steam having a higher enthalpy as a heating source for the deaerator, and taking out turbine bypass steam reheated by a reheater from a high-temperature reheat steam pipe. CONSTITUTION:Main steam supplied from a boiler 21 is carried to a high-pressure turbine 22 via a main steam pipe 23 and a stop valve 24 while exhaust gas of the boiler 21 is supplied to a mecium- and low-pressure turbine 27 via a low- temperature reheat steam pipe 26, a reheater 25, a high-temperature reheat steam pipe 28 and a stop valve 29. A low-pressure turbine bypass pipe 36 is extended between the steam pipe 28 and a condenser 35 while a high-pressure turbine bypass pipe 30 is extended between the main steam pipe 23 and the steam pipe 26. The condenser 35 is connected to the boiler 21 via a deaerator 41. At the time of turbine bypass operation, high-pressure turbine bypass reheat steam having a high enthalpy is introduced into the deaerator 41 as heated steam by opening a changeover valve 44 provided in an emergency heated-steam pipe.,下面是Turbine bypass system专利的具体信息内容。
