Title:
METHOD OF CIRCULATING HEAT MEDIUM IN STEAM POWER PLANT
Document Type and Number:
Japanese Patent JPS5644402
Kind Code:
A
Abstract:
PURPOSE:To enhance heat efficiency, by more efficiently performing the recovery and utilization or the like of waste heat discharged from the constant-pressure cooling process of steam in the main cycle of a plant whose heat medium cycle is composed of the main cycle and an auxiliary waste heat cycle. CONSTITUTION:In a main cycle, steam is sequentially conducted to a high-pressure turbine T1 and a medium-pressure turbine T2 and divided into circulating steam and discharged steam. As for the circulating steam, saturated hot water is directly ejected by a hot water ejector S1 to generate saturated steam. The saturated steam is conducted to a steam compressor C so that the steam is compressed in four stages, for example. After that, the steam enters into a superheater SH so that the steam expands at constant pressure and is supplied to a high-pressure turbine T1. The discharged steam enters into a low-pressure turbine T3 through a reheater RH2 in an auxiliary steam waste heat cycle and changes into saturated room-temperature water in a vacuum steam condenser CD. The room-temperature water is processed through mixed-type bleeder regenerator R1-R5 at various pressure stages to gradually produce high-enthalpy hot water. This hot water is supplied to ejectors S1- S3 through a heat exchanger HE.
