ELECTRIC POWER PLANT, AND METHOD FOR RUNNING THE ELECTRIC POWER PLANT
摘要
<p>Disclosed is an electric power plant such as a boiling water type nuclear power plant for feeding a high-pressure turbine and a low-pressure turbine with steam generated in a nuclear reactor. The steam discharged from the low-pressure turbine is condensed by a condenser. The water generated by the condenser passes as feed water through the feed pipe, and is heated by a low-pressure water heater and a high-pressure water heater, and is fed to the nuclear reactor. The high-pressure water heater is fed with the steam bled from the high-pressure turbine. The steam bled from the low-pressure turbine is compressed in a steam compressor so that it is heated to a raised temperature and fed to the high-pressure water heater. The feed water to be guided to the nuclear reactor is heated in the high-pressure water heater with the steam bled from the high-pressure turbine and the steam compressed by the steam compressor. Since the feed water is heated in the high-pressure water heater with the bled steam and the compressed steam, the consumption of the station power in the steam compressor can be reduced. Thus, the thermal efficiency of the plant can be enhanced in improvement of the output.</p>
