The effects of operating and geometric parameters on CaCO3 fouling in plate heat exchangers

    Research output: Chapter in Book/Report/Conference proceedingConference contribution

    Abstract

    The plate heat exchangers have been widely used in a district heating system. The fouling is unwanted deposit on the heat transfer surface, and has been a major problem for many industrial applications. The objective of this study is to investigate the effects of calcium carbonate (CaCO3) fouling on the performance of the plate heat exchangers under various operating and geometry conditions, such as concentration, flow velocity, and chevron angle. The tests were performed under accelerated concentration conditions. The fouling resistance showed an asymptotically increasing curve. The pressure drop increased with time. The fouling resistance and pressure drop increased with the increase in the chevron angle, concentration, and inlet temperature, and decreased with the increase in the flow velocity.
