摘要

This paper reports the influences of heat transfer surface properties on the formation of CaSO4 fouling deposition during flow boiling heat transfer.The surfaces of several test heaters have been treated by surface modification techniques.such as dynamic mixing ion beam implantation and dynamic mixing magnetron sputtering to reduce surface energy.Fouling runs with these heaters were carried out at different heat fluxes,flow velocities and salt concentrations.The results show that heat transfer surfaces with low surface energy experienced significantly a reduced formation of CaSO4 deposit.
