摘　　要：在简介垃圾焚烧锅炉严峻腐蚀工况的基础上,对垃圾焚烧炉受热面的腐蚀机理进行探讨,综述了近几十年来垃圾焚烧发电锅炉受热面防护技术的研究进展,并对未来的研究方向进行了展望。Waste-to-energy has become an important means to enter a low-carbon,environmentally friendly society.During the operation of waste boilers,high-temperature flue gas corrosion occurs on their key components such as water-cooled walls and superheaters.In addition,the steam temperature for power plants are also increasing significantly,which may further deteriorate the corrosion and erosion conditions for the boiler heating surface.In this severe corrosive environment,it is very important that on the heated surfaces a dense,uniform and tough coating should be applied,as well as a protective oxide scale should form on their surface to ensure the stable operation of the waste incinerator.As people continue to explore,significant progress has been made in materials and coatings with excellent corrosion resistance,such as alloy 625 overlay welding,induction fusion coating of NiCrBSi,laser fusion coating of cermets,and thermal spraying composite coatings etc.In this paper,on the basis of the introduction of the severe corrosion conditions of waste incineration boilers,the corrosion mechanism of the heating surface of waste incinerators is discussed,the research progress of the protection technology for the heating surface of waste-to-energy boilers in recent decades is reviewed,and the future research direction is prospected.
