煤粉锅炉尾部受热面飞灰磨损爆管是影响锅炉安全运行的严重问题,在锅炉“四管”爆破中占了相当大的比例。国产锅炉中以上海锅炉厂早期生产的400t/hII型锅炉省煤器磨损最为突出。不少电厂采取多种防磨措施,但因烟气速度和飞灰浓度分布不均匀的问题不能有效解决,磨损爆管仍难以避免。现将我厂对此所做的工作介绍如下。1 锅炉尾部受热面磨损的状况 The pulverized coal tube explosion heating of the tail surface of the pulverized coal boiler is a serious problem that affects the safe operation of the boiler. It occupies a considerable proportion in the “four tube” blasting of the boiler. Domestic boiler in Shanghai Boiler Factory early production of 400t / hII boiler economizer wear the most prominent. Many power plants take a variety of anti-wear measures, but due to the uneven distribution of flue gas velocity and fly ash concentration can not effectively solve the problem, wear and tear pipe is still difficult to avoid. Now I plant the work done by the following description. 1 boiler tail heating surface wear status
