Ctcs (condenser tube cleaning system) is very important cleaning device in fire (nuclear) power plants. In the pipe of heat exchanger, any tiny impurities in the formation of scale deposits will reduce the heat transfer efficiency, causing increased exhausting steam pressure of the turbine, and eventually lead to the loss of generator energy output. Therefore, keep the cleanness of the condenser tube and improve the efficiency of condenser heat transfer has a very important influence to improve thermal efficiency of the whole unit.
