摘　　要：循环流化床锅炉的排渣系统是锅炉的重要组成部分,负责将燃烧产生的大渣排出锅炉。然而,由于锅炉运行环境恶劣,排渣管经常受到高温、高压、磨损等多种因素影响,导致开裂现象频发。基于此,本文研究国外某电站锅炉本体、排渣系统、冷渣器结构及相应部件的材料和物料成分等,分析造成排渣管开裂的原因,经逐一排查和实施,最终解决了问题。The slag discharge system of circulating fluidized bed boiler is an important component,responsible for discharging the large slag generated by combustion from the boiler.However,due to the harsh operating environment of the boiler,the slag discharge pipe is often affected by various factors such as high temperature,high pressure,and wear,resulting in frequent cracking.Based on this,this article studies the materials and composition of the boiler body,slag discharge system,slag cooler structure,and corresponding components of a power station abroad.The reasons for the cracking of slag discharge pipes are analyzed,and after a thorough investigation and implementation,the problem of frequent cracking in the discharge system is finally solved.
