传热表面对电解质溶液中CaSO4结垢过程的影响
摘要
Abstract
In this paper
the formation of CaSO4 deposit on heat transfer surface is investigated both theoretically and experimentally.The test run is performed with various treated surfaces and flow velocities. Microphotograph of deposit layer is made.The results obtained are compared with untreated surface under exactly identical conditions in order to determine the suitability and the characteristics of the various treated surface.It is found that the CaSO4 deposit on the heat transfer surface can be reduced or even prevented by using surface modification techniques
such as dynamic mixing ion beam implantation and dynamic magnetron sputtering.
