CTCS (Condenser Tube Cleaning System) is a very important cleaning device in fire (nuclear) power plants. In the heat exchanger pipes, any tiny impurity in the formation of scale deposits will reduce the heat transfer efficiency, causing increased discharge steam pressure of the turbine, and eventually lead to the loss of generator energy output. Therefore, keeping the cleanness of the condenser tube and improving the efficiency of condenser heat transfer have a very important influence on improving thermal efficiency of the whole unit.
