Abstract

See full text

A system for the maintenance and operation of an air-cooled heat exchanger (ACHE) includes a plurality of spray tubes provided with spaced-apart nozzles permanently positioned between the finned heat exchange tubes and longitudinally aligned within the region of the finned-tube pitch. The system is operable in several modes, including cleaning where the flow of air is stopped and temperature-controlled pressurized water with an optional cleaning agent is discharged from the nozzles to dislodge dirt and debris from the finned surfaces while simultaneously cooling the hot process liquid. When extremes of ambient air temperatures preclude the forced air fans from achieving the target temperature range of the process liquid passing through the ACHE, refrigerated pressurized cooled water and compressed air in the form of a mist is discharged from the nozzles, or alternatively, pressurized heated air is discharged from the nozzles.
