Abstract

Heat exchanger is an important heat exchange equipment in coal chemical enterprises, due to the complexity of process medium conditions in coal chemical, the corrosion of heat exchanger directly affects the stability and safety of production and operation of enterprises. Based on the investigation and analysis of the corrosion status of heat exchangers in coal chemical enterprises, various corrosion forms, corrosion generation mechanism and influencing factors during operation were summarized, the common research methods of corrosion protection were discussed, and the working principle, advantages and disadvantages of heat exchanger were compared and analyzed, and the corrosion protection measures of heat exchanger in coal chemical industry were discussed, and the research direction, methods and development prospect of corrosion mechanism of heat exchanger in the future were prospected.

Key words： coal chemical industry heat exchanger corrosion mechanism corrosion protection
