Abstract

Способ работы тепловой электрической станции, по которому отработавший в турбине пар конденсируют в конденсаторе турбины, затем конденсат отработавшего в турбине пара отводят в линию основного конденсата турбины, которая содержит теплообменники с трубопроводами отвода дренажа и узел химводоочистки подпиточной воды, который подключают к системе регенеративного подогрева основного конденсата турбины, отличающийся тем, что исходную воду перед узлом химводоочистки подпиточной воды нагревают в конденсаторе теплового насоса, испаритель которого включают по греющей среде в трубопровод основного конденсата турбины между вторым и третьим по ходу конденсата турбины подогревателями низкого давления.The method of operation of a thermal power plant, in which the steam spent in the turbine is condensed in the turbine’s condenser, then the condensate of the steam spent in the turbine is diverted to the turbine’s main condensate line, which contains heat exchangers with drainage pipelines and a chemical water treatment unit for make-up water, which is connected to the regenerative heating system of the main turbine condensate, characterized in that the source water in front of the chemical water treatment of the make-up water is heated in a heat pump condenser, an evaporator which include in a heating medium in the pipeline of the main condensate of the turbine between the second and third along the condensate of the turbine low pressure heaters.
