Abstract
A header for a heat exchanger and method for cleaning a heat exchanger in a loop without disconnecting loop components is provided. The header is in flow communication with the heat exchanger for distributing fluid through a plurality of adjacent channels. The header is connected between a main heat exchanger inlet nozzle and a channel flow distributor. A filter element is disposed within the header between the nozzle and channel flow distributor. Under normal operation, the filter element removes particulates and fouling material from the main flow stream before it enters the heat exchanger channels. During the cleaning process, fluid is injected on or through the filter element to remove particulates and fouling material through at least one outlet port. The header arrangement allows the filter element to be 'cleaned in place' without draining the system and disconnecting the heat exchanger or other components from the flow loop.
