Anhui Vacuum Of600MW Unit In Suzhou Power Plant To Enhance The Technical Analysis And Application System

Condensing steam turbine is widely used in modern power station typical steam turbine.Condenser for condensing steam turbine unit is an important part of the。 Condensing equipment working directly affect the entire unit heat economy and reliability. Large scale thermal power plant with water ring vacuum pump as the condenser exhaust device to regulate the condenser vacuum.In this paper,the condenser vacuum system is improved in response to the national energy-saving emission reduction call, use the unit gas refrigerant to realize the heat in refrigeration, condenser vacuum system to form a circulation chilled water, to improve the purpose of condenser vacuum. The system for running a high temperature environment generating unit, have extremely great energy saving。Chapter1, describe the current situation and significance of improving the condenser vacuum.Chapter2,simple introduce the formation and influencing factors of the turbine’s vacuum.Analysis the factors of affecting condenser heat transfer performance,point out major affecting factors about the heat transfer performance of condenser---leakage of air into the condenser,introduce the working principle of the water ring vacuum pump.Chapter3,discuss the pump working fluid forced cooling device (vacuum to improve system) technology programs and the Anhui Huadian Suzhou power generation limited company No.2unit operation vacuum pump working fluid before, after the forced cooling device of condenser performance test report,and analysis the economic benefits generated.Chapter4,sums up the whole dissertation and looks forward to the further study...
