These factors have seriously influenced the security and economical operation of the unit. This paper firstly summarizes the research background and the general situation of resarch about the overheating problem of boiler's high-temperature surface ,introduces the aspects and research findings in this field such as flux deviation、thermal deviation、flue gas velocity deviation at the exit of furnace and tee bends,et al.Then analyses the reason why high-temperature surfaces are overheated from such aspects as design、manufacture、operation, et al and points out one of the main factors that cause the overheating of reheaters is the flue gas velocity deviation caused by the remaining turning at the exit of furnace.

本文首先综合论述了课题的研究背景和目前电站锅炉高温受热面超温问题的研究概况，介绍了国内外流量偏差、热偏差、炉膛出口残余旋转、&三通&等研究方向和研究成果，然后从锅炉的设计、制造、运行等方面分析了高温再热器超温的原因，指出水平烟道内气流的残余旋转是造成再热器超温的主要原因之一。

The furnace is possessed of multi-function complex lining, adjustable sub-high speed burner, burner adopting symmetric arrange, naturally draining away fume from fume offtakes, pressing soft sealing with rail, combining control by hand or automatic way.

该炉型属于台车式热处理炉，具有多功能复合炉衬和可调型亚高速烧嘴，烧嘴采用&一&字形左右对称布置，烟道为低位多点分布自然排烟，弹性接触轨道压紧软密封，自动与手动控制方式相结合。

If the old house emissions flue is not a good situation, then the best way forward is for the yin and Taiwan into the workplace, the exhaust pipe directly from the overcast outdoor Taiwan received the stove and range hood is in Taiwan Yin , so the fumes will be wiped out to cook, and kitchen cabinets can be put down more, the design can also be more subtle and reasonable.

如果老房子烟道的排放情况不是很好，那么最佳的方法就是把阴台变成工作间，把排风管直接从阴台接到室外，把灶台及抽油烟机都安排在阴台上，这样做饭的油烟就会一扫而光，而厨房也可以放下更多的柜子，设计上也可以更加巧妙合理。

As the radiation heating surface,the membrane wall is installed in the down pass of the CDQ waste-heat boiler .
