Large condenser iS one of the key heater exchange equipmems in heat—engine plant and petrochemical industry．For the unclear cooling water and chemical reactions during heat exchange when the condenser is running，the fouling which is not favorable for heat transfer is accumulated in the inner wall of condenser tube．These fouling have produced such harm：severely decreases the heat exchange capacity of the condenser,lowers the vacuum degree，increases energy consumption and probably leads to accidence due to the blockage of condenser tube and followed by erosion and perforation
