摘　　要：通过现场试验,对超超临界金属材料烟气侧抗腐蚀能力进行了评估。这些材料包括高强度铁素体钢、奥氏体钢以及高镍合金。首先在实验室中对候选材料进行试验筛选。入选的材料在电厂中被放入空冷的、可伸缩的探枪进行现场试验。试验分别在3台配有低NOx燃烧器的电站锅炉中进行,3台锅炉分别燃用3种不同代表性的煤种,并能提供符合试验要求的烟气温度。置入烟气中1年后,对其中2台锅炉的试验结果进行了初步分析。Through field testing,the fireside corrosion resistance of candidate materials for use in ultra-supercritical boilers were evaluated.These materials include high strength ferritic steels,austenitic stainless steels,and high-nickel alloys.Firstly,the materials were screened by laboratory testing.Then promising materials were assembled on air-cooled,retractable corrosion probes for field test.Three utiity boilers,equipped with low NOx burners,were identified that have adequate flue gas temperatures and represent three kinds of representative coal types.After one year exposure in the field,the fireside corrosion probes of two of the boilers vere examed and evaluated.
