Page 7: Operation
Operation Principles of condensate discharge: As much air as possible should be eliminated at start-up using a bypass valve or blowdown line. Condensate Discharge As steam is supplied, condensate flow begins. The rising condensate level causes the float to rise due to buoyancy, opening the orifice (A) and allowing condensate to be discharged. -
