Abstract

PURPOSE: To prevent the quantity of coolant at the transfer time of a heat exchanger, e.g., a condenser of an atomic power plant to a backwashing operation and the heat exchanging performance from being decreased by simultaneously closing the inlet valve and the outlet valve of a cooling tube and opening a communication valve at the transfer time and maintaining both operating times in the prescribed relationship.
CONSTITUTION: When a normal operation is transferred to the backwashing operation of the first cooling tube A, the closing operation of the first inlet valve 5 and the first outlet valve 10 and the opening operation of the first and second communication valves 14, 15 are simultaneously performed, and the time for closing the first inlet and outlet valves 5 and 10 are substantially equalized. Then, the time for opening the first and second valves 14, 15 are substantially equalized and are 1.2W2.0 times of the time for closing the first inlet and outlet valves 5 and 10. When the second cooling tube group A is transferred to the backwashing operation, similar operation is carried out with the second inlet and outlet valves 6 and 13. Thus, it can prevent the decrease of the quantity of coolant and of the heat exchanging performance at the washing time.
