<p><P>PROBLEM TO BE SOLVED: To provide a steam turbine power generating installation that improves the performance at high temperature of a steam condition of the steam turbine power generating installation. <P>SOLUTION: The installation includes: a superheater that is disposed in a boiler 20 and generates main steam; an ultrahigh-pressure turbine 11 that is driven by the main steam; a reheater in the boiler 20 that reheats exhaust of the ultrahigh-pressure turbine 11 to generate reheated steam; a high pressure turbine 12 and an intermediate pressure turbine 13 that are driven by the reheated steam; low pressure turbines 14a and 14b that are driven by exhaust of the intermediate pressure turbine 13; a water supply system 24 that supplies condensed water from a condenser 22 to the superheater of the boiler 20; a water supply pump 27 that pressurizes the water supply system 24; a pump driving turbine 32 that is driven by some of the exhaust of the intermediate pressure turbine 13 and drives the water supply pump 27; and a desuperheater 31 that is disposed at an inlet of the pump driving turbine 32. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
