Abstract
Generally, it is a method to remove the fouling cleaning the plate heat exchanger with chemicals or polishing with a brush or cloth after stopping the equipment and disassembling heat exchanger. However, the equipment must be stopped and taken apart when using this method, which causes an unnecessary work to assemble again after cleaning it. In this study, it has developed and tested the equipment which can automatically clean the fouling on plate heat exchanger at regular intervals with air bubbles. It indicated that the overall heat transfer coefficient had decreased without significant differences similar to that calculated without air bubbles until after 72 hours when making air bubbles to remove fouling ingredient on the surface of heat transfer area every 10 minutes per 2 hours. However, it showed that there was a 10% higher of heat transfer effect compared to the case without air bubbles of after 192 hours.
