Изобретение относится к способу охлаждения паровой турбины низкого давления в режиме вентиляции. Паровая турбина низкого давления содержит перекрываемый впуск, через который в режиме мощности подают пар и который заперт в режиме вентиляции, сообщающийся с конденсатором для конденсации пара в конденсат выпуск а также место ответвления между впуском и выпуском. К месту ответвления подключен заборный трубопровод для отвода пара и/или конденсата в режиме мощности. Согласно изобретению, для охлаждения паровой турбины низкого давления в режиме вентиляции в заборный трубопровод подают пар по перепускному трубопроводу пара. Предпочтительно также в заборный трубопровод подводить конденсат. Охлаждающее действие в паровой турбине низкого давления в значительной степени ограничено сильно нагруженными в режиме вентиляции компонентами, а средства для охлаждения отбираются из ресурсов, которые имеются в распоряжении.The invention relates to a method for cooling a low-pressure steam turbine in the ventilation mode. The low-pressure steam turbine contains an overlapped inlet through which steam is supplied in power mode and which is locked in ventilation mode, communicating with a condenser to condense steam into a condensate outlet and also a branch point between inlet and outlet. The intake piping is connected to the branch point to remove steam and / or condensate in the power mode. According to the invention, in order to cool a low-pressure steam turbine, in the ventilation mode, steam is supplied to the intake pipe via a steam bypass pipe. It is also preferable to supply condensate to the intake manifold. The cooling effect in the low-pressure steam turbine is largely limited to heavily loaded components in the ventilation mode, and the means for cooling are taken from the resources that are available.
