Abstract

To solve the problem of high-temperature metal corrosion on the heating surface of coal-fired boilers and biomass boilers, this paper analyzes and studies the high-temperature corrosion mechanism and protection technology of coalfired boilers and biomass boilers. It mainly discusses the corrosion mechanism of sulfate-type corrosion, chloride-type corrosion, and sulfide-type corrosion of coal-fired boilers. The research and application status of the two major protective coating technologies of high-temperature nano-ceramic coating technology and metal-based composite coating are further discussed. Aiming at the corrosion mechanism of biomass boilers with high-temperature chlorine corrosion as the mainstay, the inhibitory effect and effect of additives on high-temperature metal corrosion are emphasized.
