| Abstract: | The data of water-steam cation conductivity in a gas-steam combined cycle unit has abnormally in creased. The influence of on-line in struments, sampling system and recharge water on cation conductivity were comprehensively analyzed. The leakage points of condenser were detected by using condenser leak detector. The initial plugging was carried out by adding wood chips, and the leakage occured at the connection between the pipe and pipe plate was dectected by means of membrance covering method and timely treated. After timely treatment, the water-steam cation conductivity is restored to normal level, which ensure the safe and stable operation of the unit. |
