Current status and future trends of high-temperature gas environment corrosion on metal coatings in solid waste incinerators

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.
