Analysis on Chilled Water Spraying through Extraction Opening in Condenser to Enhance Extraction Effect of Vacuum Pump

Abstract:

Non condensable gas (air) accumulating in the condenser will reduce heat transfer coefficient of condense and vacuum value, Reducing of condenser vacuum value will lower turbine efficiency. Chilled water spraying is adopted to cool down the steam before it is extracted through extraction opening in condenser so as to enhance extraction effect of vacuum pump. This paper gives analysis on chilled water spraying through extraction opening. Mathematic model of selected controlling volume near extraction opening is given. Maximum amount of spraying and its relationship with vacuum value and increment of extraction rate are also proposed.
