Abstract

1. 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 добавочной питательной воды, который подключают к системе регенеративного подогрева основного конденсата турбины, отличающийся тем, что исходную воду перед узлом химводоочистки добавочной питательной воды нагревают в конденсаторе теплового насоса, испаритель которого включают по греющей среде в трубопровод основного конденсата турбины между первым и вторым по ходу конденсата турбины подогревателями низкого давления.2. Способ работы тепловой электрической станции по п.1, отличающийся тем, что подачу добавочной питательной воды в трубопровод основного конденсата турбины осуществляют между испарителем теплового насоса и вторым по ходу конденсата подогревателем низкого давления.1. The method of operation of a thermal power plant, in which the steam exhausted in the turbine is condensed in the turbine’s condenser, then the condensate of the steam exhausted 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 additional feedwater, which is connected to the system regenerative heating of the main condensate of the turbine, characterized in that the source water in front of the chemical water treatment unit of the auxiliary feed water is heated in a condenser a new pump, the evaporator of which is switched on through a heating medium into the pipeline of the main condensate of the turbine between the first and second low-pressure heaters along the turbine condensate. 2. The method of operation of a thermal power plant according to claim 1, characterized in that the supply of additional feed water to the main condensate pipeline of the turbine is carried out between the heat pump evaporator and the second low-pressure heater along the condensate.
