摘要
分析了国产单布风板、不带外置换热器的1065 t/h亚临界循环流化床锅炉运行调节特性,以及运行过程中的主要问题,并提出了解决方案。结果表明:锅炉长期运行稳定,低负荷性能好,总体效果令人满意,但锅炉存在高负荷下主汽温度偏低的问题;提出将两片水冷屏改为中温屏式过热器的方案,锅炉运行特性及改进方案为大容量循环流化床锅炉的优化设计与运行提供了参考。
The domestic 1065 t/h subcritical reheating circulating fluidized bed （CFB） boiler without external heat exchanger are presented under the different loads, and the main problems occurring during operation as well as corresponding solutions are analyzed. The results show that the boiler can stable operation in long term, good performance at low load, but the main-steam temperature lower than design values. The problem of main-steam temperature lower than design values may be solved by changing the two of water-cooled evaporating panel into superheated panel. The operation characteristics of this boiler may serve as a reference for optimized design and operation of large-scale CFB boilers.
