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 pipeline with steam boiler to which bleed and feed water pipelines are connected, high-pressure regenerating heaters placed in feed water pipeline and connected to turbine steam extraction by heating medium lines. Water-to-water heat exchanger connected to bleed water pipeline is connected by heated medium pipeline to condensate line of high-pressure regenerative heater last in direction of feed water flow, and pipeline of condensate of this heater heated by bleed water is connected after water-to-water exchanger through pump to feed water pipeline before boiler. ^ EFFECT: increased economy owing to reduction of capital outlays and enlarged sphere of application of invention. ^ 1 dwg |
