Waste　incineration　is　an　important　component　of　solid　waste　management　systems　in　cities　worldwide,　offering　advantages　such　as　rapid　waste　volume　reduction,　heat　recovery,　and　power　generation.　However,　the　power　efficiency　of　waste-to-energy　plants　is　relatively　low,　primarily　due　to　constraints　imposed　by　high-temperature　corrosion.　The　temperature　and　gas　composition　in　the　waste　incineration　boiler　are　critical　factors　affecting　high-temperature　corrosion.　Therefore,　a　comprehensive　review　of　the　behavior　of　temperature　and　gas　composition　during　incineration　is　needed.　From　the　perspective　of　influencing　factors　on　high-temperature　corrosion,　this　article　provides　an　overview　of　the　corrosion　mechanisms　and　existing　coating　research　under　different　factors,　such　as　temperature　and　gas　composition　(chlorine,　sulfur,　fluorine,　bromine)　present　in　waste　incineration　boilers.　The　article　identifies　current　research　and　application　challenges　and　prospects　for　future　development　trends,　offering　important　reference　value　for　the　further　application　and　promotion　of　metal　coatings　in　waste　incinerators.
