FIELD: heat power engineering; thermal power stations. ^ SUBSTANCE: invention is designed for use of heat of bleed water in thermal power stations. Proposed thermal power station has steam turbine connected by live steam line with steam boiler to which bleed and feed water pipelines are connected, and high-pressure regenerative heaters placed in feed water pipeline and connected to steam turbine steam extractions by heating medium lines. Water-to-water heat exchanger connected to bleed water pipeline is connected by heated medium line to condensate line of regenerative high-pressure heater last in direction of feed water flow, and pipeline of condensate of said heater heated by bleed water is connected after water-to-water heat exchanger through pump to feed water pipeline between first and second stages of economizer. ^ EFFECT: increased economy owing to reduction of capital outlays and enlarged sphere of application of invention. ^ 1 dwg |
