What are the cooling methods for steam turbines?
Thread Content
What are the current turbine cooling methods using electric fields? Are fire power, hydro power, and nuclear power the same?
Hehe, OP, your question is a bit strange. Do the steam turbines we use need to be cooled? If you’re asking how the steam generated by the turbine after it has done its work is cooled, then in the case of condenser-type turbines like those we use, cooling is achieved through a large heat exchanger; back-pressure type turbines, on the other hand, don’t require such a system!
To ensure the proper operation of the turbine, cooling is necessary under special operating conditions; this is generally achieved through hydrogen cooling or oil cooling, with some studies also mentioning forced ventilation cooling
For condenser-type systems, condensers are always used; however, in our plant’s back-pressure systems, there is a gas seal heater that uses soft water to cool the leaked gas, and the cooled gas is then sent to the condenser-type condenser.
Like nuclear power, thermal power is not needed for hydroelectric power
Turbine exhaust steam is generally of two types: water-cooled and air-cooled.
What are the methods of cooling turbines? Question from the poster: What are the methods of cooling turbines? To answer this question, I would like to start by discussing the following aspects: 1. The waste steam generated after the condensing turbine has done its work enters the condenser where it undergoes surface heat exchange; the heat is transferred to the circulating water through the tube walls, and the waste steam condenses into condensate water, which is then sent back to the boiler for reuse. 2. The cooling methods for steam turbine generators include air cooling, hydrogen cooling, and double-water internal cooling. 2. Some auxiliary machines also need to be cooled, such as oil coolers and shaft seal coolers.
Passing by, learning*. Thank you to all the sea friends for their answers.
In the case of a condensing unit, cooling is achieved through a condenser; however, it is necessary to maintain a vacuum level that is not too low. Front and rear steam seals are also used to preserve this vacuum, so as to prevent the temperature in the exhaust cylinder from rising too high. There are no particular requirements for back-pressure units; the exhaust pressure is simply used, with low-pressure pipelines to maintain it.
Thank you all for your answers. I’m not very familiar with this area either, so my question was a bit vague; what I actually wanted to ask was about the cooling method of the rotor
