Description
Изобретение относитс к области теплоэнергетики и может быть использовано при получении пиковой мощности.The invention relates to the field of power engineering and can be used to obtain peak power.
Известны энергетические установки, содержащие паротурбинный блок с отборами, подключенными к регенеративным подогревател м и подогревател м воздуха, и парогазовый блок с газотурбинным агрегатом, парогенератором и паровой турбиной с отборами.Power plants are known that contain a steam turbine unit with selections connected to regenerative air preheaters and air preheaters, and a vapor-gas unit with a gas turbine unit, a steam generator and a steam turbine with selections.
Целью изобретени вл етс повышение экономичности и надежности выработки пиковой мощности при отключении отборов паротурбинного блока.The aim of the invention is to increase the economy and reliability of peak power generation when disconnecting steam turbine unit selections.
Это достигаетс тем, что выхлоп и отборы паровой турбины парогазового блока соединены с подогревател ми паротурбинного блока.This is achieved by the fact that the exhaust and sampling of the steam turbine of the combined-cycle unit are connected to the heaters of the steam-turbine unit.
На чертеже изображена схема предложенной энергетической установки.The drawing shows a diagram of the proposed power plant.
Паротурбинный блок установки содержит парогенератор /, паровую турбину 2 с электрогенератором 3, систему регенеративных подогревателей 4 и паровые подогреватели воздуха 5.The steam turbine unit of the installation contains a steam generator /, a steam turbine 2 with an electric generator 3, a system of regenerative heaters 4 and steam air heaters 5.
Парогазовый блок состоит из компрессораThe steam-gas unit consists of a compressor
6,приводимого в движение газовой турбиной6 driven by a gas turbine
7,парогенератора 8, соединенного с противодавлевческой паровой турбиной 9. Дл утилизации уход щих газов газовой турбины предусмотрен газовод ной подогреватель 10.7, a steam generator 8 connected to an anti-pressure steam turbine 9. A gas-water heater 10 is provided for utilization of the exhaust gases of the gas turbine.
Отборы и выхлоп турбины 9 соединены с регенеративными подогревател ми 4 и подогревател ми воздуха 5.The extraction and exhaust of turbine 9 are connected to regenerative heaters 4 and air heaters 5.
При необходимости получени пиковой мощности параллельно с паротурбинным блоком вступает в работу парогазовый блок. Дополнительна мощность вырабатываетс в паротурбинном блоке за счет увеличени расхода при отключении отборов турбины 2 и в парогазовом блоке.If it is necessary to obtain peak power in parallel with the steam turbine unit, the steam-gas unit enters into operation. Additional power is generated in the steam turbine unit by increasing the flow rate when disconnecting the turbine selections 2 and in the steam-gas unit.
Подогреватели 5 .и подключены в это врем к отборам и выхлопу турбины 9.Heaters 5 .and are connected at this time to the extraction and exhaust of the turbine 9.
