Abstract

PURPOSE:To enable operation with high reliability, by installing a regulating valve on low pressure steam line and a pressure regulator on the upper side of the line and controlling by said pressure regulator the pressure of the low pressure part of a waste heat recovery boiler for the multiple pressure gas turbine at a constant pressure level. CONSTITUTION:In a combined-power plant, a generator 32 is driven by heating a waste heat boiler 20 with the exhaust gas of high temperature and pressure after having performed work in a gas turbine 13, and leading steam thus generated to a steam turbine 31 via a main steam line 52. In this case, in the boiler 20 is installed a low pressure evaporator 25 generating low pressure steam by leading a part of the feed water. The low pressure steam generated therein is led to turbine 31 via a low pressure steam line 55. A valve 57 is interposed on the low pressure steam line 55 to make the pressure of the low pressure steam line 25 equal to the pressure of the compound stage of the turbine 31. And on the upper side of the valve 57 of the steam line 55, a pressure regulator 56 is installed so as to control inlet pressure for the valve 53 at a certain level.
