Изобретение относитс к способам выработки электроэнергии преимущественно на конденсационных тепловых и атомных электростанци х, использующих в качестве рабочего тела вод ной пар и пар низкокип щего вещества .The invention relates to methods for generating electricity primarily at condensing thermal and nuclear power plants using water vapor and low boiling substance vapor as a working fluid.

Цель изобретени - повышение экономичности путем экономии топливаThe purpose of the invention is to increase efficiency by saving fuel.

На чертеже представлена схема электростанции дл реализации предлагаемого способа.The drawing shows the scheme of the power plant for the implementation of the proposed method.

Электростанци содержит первый контур высококип щего теплоносител , состо щий из котла 1, соединенного с турбогенератором 2, выхлоп которого выведен на конденсаторы паропере- греват ели 3-5, и насоса 6, а также второй контур низкокип щего вещества , включающий турбогенератор 7, к которому подключен через конденсаторы-пароперегреватели 3-5 источник 8 вторичных энергоресурсов (ВЭР), например солнечный пруд и/или контактный экономайзер, котел-утилизатор , и др., а к выхлопу турбогенератора 7 подключен конденсатор 9 низкокип щего вещества, который через питательный насос 10 подсоединен через дроссель к источнику 8 ВЭР,The power plant contains the first circuit of a high-boiling heat carrier, consisting of boiler 1, connected to a turbo generator 2, whose exhaust is led to condensers by superheating spruce 3-5, and pump 6, as well as a second circuit of low boiling substance, including a turbo generator 7, to which connected through condensers-superheaters 3-5 a source of 8 secondary energy resources (VER), such as a solar pond and / or contact economizer, a waste-heat boiler, etc., and a low-boiling condenser 9 connected to the exhaust of the turbogenerator 7 th through the feed pump 10 is connected through a choke to the source 8 VER,

Предлагаемый способ осуществл ют следующим образом.The proposed method is carried out as follows.

Вод ной пар из котла 1 направл ют в турбогенератор 2 и далее в конденсаторах-пароперегревател х 3-S его конденсируют, а конденсат возвращают в котёл 1,Water vapor from boiler 1 is sent to the turbogenerator 2 and then condensed in the steam superheaters 3-S, and the condensate is returned to boiler 1,

Claims

The low boiling point substance is evaporated using, for example, a solar pond 8, into which heat of the flue gases from boilers is also discharged, and. other sources of VER. The resulting steam is overheated by exhaust and selections from the turbo-generator.

2. The resulting superheated steam is sent to the turbogenerator 7 and further to the condenser 9. By pump 10 through the choke 11, the condensate of the low boiling point substance is fed to the evaporation to the source 8 VERO

The method of operation of a binary condensation power plant with turbofan circuits of low-boiling and high-boiling coolants is by evaporation of both coolants, superheating of low-boiling coolant steam, supplying both coolants to the turbogenerators of the corresponding circuits with electricity generation and their subsequent condensation, and the high curtain syringe has a curtain for the generators of the corresponding circuits with electric power generation and subsequent condensation, and a high drawing cylinder is used; coolant, characterized in that, in order to increase efficiency by saving fuel, before s low boiling heat transfer fluid for condensing high boiling heat transfer fluid it is further heated and vaporized secondary heat energy and / or of renewable energy sources and condensing high boiling heat transfer fluid overheating are low boiling heat transfer fluid.
