The Status and Progress of Corrosion Protection in Waste Incinerator Circulating Fluidized Bed Boiler

Gaseous sulfide and sulfate corrosion has been considered to cause high temperature corrosion in waste incinerator.In recent years,the study found that the effect of chlorine was the most important.In this paper,the status of chloride corrosion,high temperature chlorine corrosion mechanism and the status of the research on the surface protection were introduced.The authors prospected that to develop a new thermal sprayed coating arc to solve the problems of high temperature corrosion occurred on the water wall.
