H:dxntevoven/MNRPonbIDCCDXL/6,579 419, Ldo-5/08/2A 4 A steam turbine plant comprising: a boiler configured to change water into steam; an upstream turbine including plural stages of rotor vanes and plural 5 stages of stator vanes, and configured to be driven by the steam from the boiler; a downstream turbine including plural stages of rotor vanes and plural stages of stator vanes, connected to the upstream turbine via no reheater, and configured to be driven by the steam from the upstream turbine; a condenser configured to change the steam exhausted from the downstream turbine into water; a collector 10 configured to collect water from the steam which exists upstream of an inlet of the final stage rotor vane in the upstream turbine; and a collected matter path configured to cause collected matter in the collector to flow into: the water between the condenser and the boiler, the steam extracted from an extraction port of the upstream turbine or the downstream turbine, a feed-water heater configured to 15 receive the extracted steam from the extraction port of the upstream turbine or the downstream turbine, or a feed-water pump driving steam turbine configured to receive the extracted steam from the extraction port of the upstream turbine or the downstream turbine. -108 202 P -1 112- 203 X204 107 211- E Y= E G 201 P ) 115 -120 E120-,120 212 p 0# 11 1 )1 12 12.1 1 -213 20 1 P ::- 11 121 122 121 105 ~213 |
