Electric power plant, and method for running electric power plant |
摘要 |
An electric power plant supplies steam generated to a high-pressure turbine and a low-pressure turbine. The steam discharged from the low-pressure turbine is condensed with a condenser. Water generated with the condenser is heated with a low-pressure feed water heater and a high-pressure feed water heater. The steam extracted from the high-pressure turbine is supplied to the high-pressure feed water heater. The steam extracted from the low-pressure turbine is compressed with a steam compressor, and the steam whose temperature has been increased is then supplied to the high-pressure feed water heater. The feed water is heated in the high-pressure feed water heater by the steam extracted from the high-pressure turbine and the steam compressed with the steam compressor. Because the feed water is heated by the extracted steam and the compressed steam in the high-pressure feed water heater, the amount of power consumed by the steam compressor can be reduced.
