FIELD: power industry. ^ SUBSTANCE: in operating method of thermal power plant, as per which liquid fuel is heated in surface steam heaters connected to pipeline before boilers, as well as in surface heaters of fuel storage, in evaporator of heat pump unit there cooled is condensate of heating steam of surface steam heaters of liquid fuel, which are connected to pipeline upstream of boilers, and in condenser of heat pump unit there heated is water used as heating agent in surface heaters of fuel storages. ^ EFFECT: invention allows improving economy and reliability of thermal power plant due to reduction of heat losses with heating steam condensate of surface steam heaters connected to pipeline before boilers, as well as due to replacement of high-potential heating agent, namely steam with pressure of 0,8-1,3 MPa, in surface heaters of fuel storage with more low-potential heating agent. ^ 1 dwg |
