摘　　要：锅炉安装节能器可显著提高锅炉的热效率及能源利用率。因此,锅炉节能器的平稳运行是保障锅炉热效率的基础及关键。本文综述了锅炉节能器的典型失效行为及机理,分析了节能器失效的主要影响因素,并提出了相应的防护措施,对于充分利用节能器在燃气锅炉余热回收中的作用具有重要的现实意义,对于提升锅炉节能器的服役寿命具有一定的指导意义。After installing the economizer in the boiler, the thermal efficiency and energy utilization rate of the boiler can be significantly improved. Therefore, the stable operation of boiler economizer is the ba-sis and key to ensure the thermal efficiency of boiler. This paper summarizes the typical failure be-havior and mechanism of boiler economizer, analyzes the main influencing factors of economizer failure, and puts forward corresponding protective measures. It has important practical significance for making full use of the role of economizer in waste heat recovery of boiler, and has certain guid-ing significance for improving the service life of boiler economizer.
