The quality of condensate water in thermal power plant affects the fouling,corrosion and flow resistance of the whole steam-water system equipment,and further the safety and reliable operation of the power unit.Intermittent abnormal quality in condensate water occurred in a 1030MW power unit.Through analysis,the probobilities on the leakage of condenser circulating cooling water,the sample and analysis error of water pollution at condensate pump outlet,unqualified water quality of condenser water supply were excluded.Combined with field tests and theoretical calculations,the weld leakage of condensate pump barrel was proved to be the source for the occurrence of intermittent abnormal condensate water quality.
