플레이트 열교환기의 공기방울에 의한 파울링 제거 및 용존산소 제거 효과

Abstract

This paper presents an effect of air bubbles in a plate heat exchanger on fouling & dissolved oxygen removal. Fouling is the deposit that disturbs heat transfer on the heat exchanger surface. As a result the heat transfer performance of heat exchanger plate decreases as time goes by. It has developed and tested the equipment which can clean the fouling on heat exchanger plates automatically per constant period and interval using air bubbles. Value of dissolved oxygen showed lower more than 11% when using both an air separator and dissolved oxygen eliminator compared to using only an air separator.
