摘要： PURPOSE:To prevent drop in temperature, etc. of a feed water heater caused by depression in turbine bleed during turbine bypass operation by providing a bypass steam supply pipe through which turbine bypass steam is supplied into a feedwater line through desuperheaters. CONSTITUTION:Steam generated in a boiler 1 is guided to successively pass through a high-pressure turbine 5, a reheater 7, an intermediate pressure turbine 10, and a low pressure turbine 11 to carry out work, before it is introduced to a condenser 12 and condensed, and the condensate is returned to a boiler 1 through a heater 15, a degasifier 16, and a heater 18. In a plant of such construction, a bypass steam supply pipe 25 is branched out from a low pressure turbine bypass pipe 22 at a position adjacent to a bypass valve 21 on the lower course. The first and the second bypass-steam supply pipes 25a, 25b are branched from the pipe 25, and desuperheaters 26, 29 are provided in the pipes 25a, 25b respectively. And, the pipe 25a is connected to a high-pressure feedwater heater 18, and the pipe 25b is connected to a low-pressure feedwater heater 15 respectively.
