Question:

Stop the engine immediately and stop the circulating pump and the condensate pump. What's the harm to the turbine?

Stop the engine immediately and stop the circulating pump and the condensate pump. What's the harm to the turbine?

Answer:

Stop the condensate pump is not required to condensate users, such as reducing water, mechanical seal water, shaft seal cooling water, deaerator, whether you need water. Stop circulating pump requires three: 1, exhaust steam temperature below 50. 2, there is no circulating water users. 3. No drain to condenser. If stop immediately stop circulating water and condensate pump, the consequences can be imagined.
The condensed water is also used to air pumping device, steam seal cooler as cooling water, according to rules of turn.The circulating water is also used to supply cooling water to the oil cooler, and the oil temperature will rise.Hazard: exhaust pipe, condensate pipe will burst tube, low pressure cylinder rising temperature for deformation, rotor (shaft seal) may be deformed.
Then look at what is the circulating water pump and condensate pump users, circulating water with oil in the oil cooler then, condensed water supply pump seal water, water pump can't pump up, how will you know.
