Description
Изобретение относитс к теплоэнергетике и может быть использовано на тепловых электростанци х.The invention relates to a power system and can be used in thermal power plants.
Цель изобретени - повышение надежности путем обеспечени безэрозионной работы последних ступеней теплофикационной турбины.The purpose of the invention is to increase reliability by ensuring eerologic operation of the last stages of a cogeneration turbine.
На чертеже изображено устройство дл осуществлени предлагаемого способа охлаждени последних ступеней теплофикационной турбины.The drawing shows a device for carrying out the proposed method for cooling the last stages of a cogeneration turbine.
Устройство содержит трубопровод 1 подачи рабочего пара, подключенный к цилиндру 2 низкого давлени , содержащего неохлаждаемые ступени 3, включенные перед камерой 4 регулируемого отбора, запорное устройство 5, охлаждаемые пр моточно ступени 6 и охлаждаемые в противоток ступени 7, а также вы.хлопной патрубок 8, подключенный к конденсатору 9, на который подаетс охлаждающа вода.The device comprises a working steam supply pipe 1 connected to a low pressure cylinder 2 containing uncooled stages 3, connected in front of an adjustable takeoff chamber 4, a locking device 5, stages 6 and counterflowed cooled stages 7, as well as a exhaust pipe 8 connected to condenser 9 to which cooling water is supplied.
К охлаждаемым ступен м 6 и 7 подключена парокомпрессионна установка 10, напорна камера которой посредством трубопровода 1 1 пара подключена к теплообменнику 12, к которому в свою очередь грубопроводо.м 13 подключена ступень 6 турA vapor compression unit 10 is connected to the cooled stages 6 and 7, the pressure chamber of which is connected via a pipeline 1 1 to the heat exchanger 12, to which, in turn, the coarse pipe 13 connects the stage 6 round
бины. Конденсат греющего пара теплообменника 12 по трубопроводу 14 поступает в конденсатор 9.bins The condensate of the heating steam of the heat exchanger 12 through the pipeline 14 enters the condenser 9.
Способ охлаждени последних ступеней теплофикационной турбины на малорасходных режимах осуществл ют следующим образом .The method of cooling the last steps of the heat-generating turbine in low-flow conditions is carried out as follows.
Рабочий пар, подаваемый по трубопроводу 1, срабатывает в неохлаждаемых ступен х 3 и затем раздел етс на два потока . Один из них по трубопроводу 13 поступает в теплообменник 12, а другой - вентил ционный,проход через нормально закрытое запорное устройство 5, охлаждает ступени 6.The operating steam supplied through conduit 1 is triggered in uncooled steps x 3 and then divided into two streams. One of them, via pipeline 13, enters the heat exchanger 12, and the other is the vent, the passage through the normally closed locking device 5 cools the stages 6.
В конденсаторе 9 генерируют пар, идущий на охлаждение ступеней 7 в противоток вентил ционному, путем подачи перегретого относительно температуры насыщени при давлении в конденсаторе конден сата греющего пара теплообменника 12. Необходимое при этом давление в конденсаторе 9 создаетс за счет отсоса охлаждающего последние ступени 6 и 7 пара парокомпрессионной установкой 10, напорна сторона которой подключена к теплообменнику 12.In the condenser 9, steam is generated, which goes to cool the steps 7 to the countercurrent flow to the ventilation, by supplying a heating steam of the heat exchanger 12 superheated relative to the saturation temperature under pressure in the condenser. steam vapor compression installation 10, the discharge side of which is connected to the heat exchanger 12.
