摘　　要：灰行为研究是煤燃烧和煤气化技术的关键，美国能源与环境研究中心在这方面一直保持着领先地位。在1995～1997期间，33项动力系统研究项目中，有10项是关于或涉及灰行为的研究项目。这些项目根据动力系统的实际运行情况和实验室的实验结果分析，对煤燃烧、气化等条件的结渣结焦机理进行了研究，特别是在配煤燃烧、流化床锅炉、低NOx情况以及减土金属在结渣结焦机理中的作用取得了结论。降低锅炉运行温度、合理配煤和使用吸减剂可以缓和或解决系统的结焦和结渣。Ash boavior study is key to coal combustion and gasification technology.America Energy and Environmental Research Center has always been in the leading positionin this field. During 1995-1997, there were 10 prosects about or involving ash behavioramong 33 researching proJects of dynamic system. These projects made research oncoking and slagging mechanism under conditions of coal combustion and gasiffcationaccording to actual operation of dynamic system and analysis of test results, and madeconclusions ou functions of firing with coal, fluidized bed, low NOx as well as alkaliearth metal in coking and slagging mechanism. Reducing boiler operating temperature,reasonable coal allocation and applying alkali absorbent are able to alleviate or solvecoking and slagging in the system.
