摘　　要：本文详细介绍了国内外不同技术流派循环流化床锅炉外置式换热器的典型结构和技术特点,归纳了在役锅炉外置式换热器的常见问题,分析问题产生原因并给出处理建议。根据《锅炉定期检验规则》,结合外置式换热器检验的经验,明确了外置式换热器定期检验过程中的检验重点和常见缺陷。The typical structure and technical characteristics of the external heat exchanger of circulating fluidized bed boiler were introduced in this paper, including those made by different technical schools. The common problems of the external heat exchanger during operation were generalized, and the cause of the problems and processing recommendations were analyzed. According to the ＂Boiler Periodical Inspection Regulation＂, combined with the experience of external heat exchanger inspection, inspection focus and common defects of the external heat exchanger were given clearly.
