FIELD: heat power engineering. ^ SUBSTANCE: proposed thermal power station contains at least one steam turbine with process and heating steam extraction, systems of regenerative and line heaters and station medium steam pressure manifold to which combination evaporator plant with multistage evaporator set, heating steam condensate expander of separate evaporator stages, deaerator of multistage evaporator plant and flashing evaporator plant are connected. Cooler of distillate from expander is placed in water pipeline of deaerator of multistage evaporator plant. Source water pipe-line from end condenser of flashing unit evaporator plant is connected through heater, chemical water cleaning unit and pump, to pressure manifold of makeup water of flashing evaporator plant, multistage evaporator plant and heating system. Pipelines of distillate from expander of multistage evaporator plant and flashing evaporator plant are connected to additional water atmospheric deaerator. Water pipeline from atmospheric deaerator is connected to main condensate line of steam turbine. ^ EFFECT: increased thermal economy of station. ^ 1 dwg |
