Help needed: turbine, surface cooler vacuum
Thread Content
Isn’t the vacuum in the surface cooler of a properly operating turbine maintained by an ejector?
It can be said that the surface cooler is used for cooling, and any remaining non-condensable gas is removed by air extraction
It mainly relies on coolers, while some non-condensable gases are removed using extractors. Therefore, the condensation efficiency of the condenser has a significant impact on the vacuum level.
The vacuum level is primarily achieved by cooling the waste steam with an air cooler; the pump simply removes the non-condensable gases in a timely manner to maintain the vacuum level in the air cooler
