摘要： In order to obviate a short life and an expensive maintenance cost of boiler throttle valves as well as plant loss caused by pressure reduction at the boiler throttle valves in a supercritical pressure once-through boiler a supercritical pressure once-through boiler, in which boiler water transformed into steam in boiler furnace wall tubes is further heated in a superheater and is then fed to a main turbine, is improved in that boiler throttle valves and a heat recovery apparatus are provided on the downstream side of the boiler furnace wall tubes.
