What happens when vacuum is lost from running condenser?
What happens when vacuum is lost from running condenser?

water halting or water shortage. large amount of leakage in the vacuum system. full water in the condenser. halt of steam supply from the bearing seal. fault at the water jet pump. improper operation at the vacuum system valve. wrong opening vacuum breaking gate. damage at the diaphragm of the safety valve.
Why is vacuum lost or not maintained in steam turbine?
The greatest trouble in running the steam turbines is the loss of vacuum caused by air leaking into the surface condenser through the joints or packing glands. Another trouble spot is cooling water leaking into the steam space through the ends of the tubes or through tiny holes in…
