ABSTRACT:
A method of operating a heat exchange system of the type adapted to receive a hot fluid and a cool fluid therethrough accomplishes cleaning of the system by terminating cool fluid flow to a portion of the system. Both fluids are passed through the entire system for a period of time. Flow of the cool fluid is then terminated to a portion of the system while continuous flow of the hot fluid is maintained through the entire system. Thus, the operating temperature of the entire system is increased so as to melt wax and other deposits on surfaces in the system.
