Fouling is termed as the accumulation of undesirable substances on the surface of heat exchangers. It usually forms from the precipitation of dissolved mineral salts, which reduces the heat transfer rate and introduces corrosion on the heat transfer surface. Thus, it is mandatory to explore sustainable sources to inhibit the fouling and corrosion on heat exchanger surfaces. The present study investigated heat transfer improvement and retardation of CaCO3 fouling and corrosion by applying a thin graphite layer coating on the heat transfer surface. The results revealed that the graphite-coated surface enhanced the heat transfer and retarded fouling deposition and corrosion.
