摘　　要：以50 MWe循环流化床锅炉的防磨损技术优化设计为背景,针对因炉膛受热面的磨损泄漏而导致非计划性停炉的问题,主要分析了循环流化床锅炉炉内受热面的磨损主要存在燃烧区域大、煤粒粒径偏中、温度梯度小、燃烧中心温度低等特点,进一步提出了循环流化床锅炉炉膛受热面整体防磨和局部防磨有效措施,运行实践证明,采取上述措施,使受热面的磨损情况得到了有效的控制。To prevent wear technology optimization design under the background of the 50 MWe circulating fluidizedbed boiler, furnace for heating surface wear and leakage, resulting in unplanned shutdown of the problem, this paperanalyzes the circulating fluidized bed boiler heating surface wear of the combustion area, coal particle size deviation,temperature gradient is small, the center of the combustion temperature is low, puts forward the overall anti abrasionand anti abrasion measures of local heating surface of circulating fluidized bed boiler, operation. It is proved bypractice that the wear of heating surface has been effectively controlled by adopting the above measures.
