Abstract：

The research progress on the corrosion of key heat transfer components of boilers in domestic waste incineration power plants was reviewed. The corrosion characteristics and mechanism of three common corrosion types including chlorine corrosion, sulfur corrosion and alkali metal salt corrosion have been discussed respectively. Factors affecting corrosion were analyzed，such as metal materials, temperature, corrosive medium content, water vapor and heavy metal elements. The main achievements and shortcomings of the current research were summarized, and on this basis, further research directions were also proposed.

Key words： waste incineration chlorine sulfur alkali metal coupled corrosion
