摘　　要：燃煤锅炉结焦是影响锅炉安全和经济运行的重要因素。某热电公司的2台300 MW机组锅炉运行时水冷壁区域存在严重的结焦、结渣及高温腐蚀问题。为避免结焦与高温腐蚀带来的强迫停运风险,该公司在对锅炉结焦的原因、危害及国内外的研究现状进行总结分析的基础上,采用新型防结焦技术——高温纳米陶瓷涂层技术。实践结果表明,该技术不仅可以改善锅炉的安全运行状况,还可以提高锅炉的效率。Coal boiler coking is an important factor affecting boiler safety and economic operation.There are serious coking slag and high temperature corrosion problems in the water-cooled wall area in two 300MW unit boilers of a thermal power company.In order to avoid the risk of forced shutdown caused by coking and high temperature corrosion,a new anti-coking technology,the high temperature nano-ceramic coating technology,is proposed to improve not only the safe operation of boilers,but also the efficiency of boilers.
