Fouling in the operation of the equipment will reduce the heat transfer efficiency of the equipment, the flow area in the pipeline will also decrease, and the flow resistance will also increase, making the load of the entire equipment worse. Production efficiency is reduced. When this happens, stop the equipment to remove dirt to improve the production efficiency of the equipment.
The meaning of heat exchanger cleaning:
