贵州超临界双拱燃烧锅炉垂直管屏水冷壁安全性分析及调整措施

Guizhou Supercritical Double Arch Boiler Safety Analysis and Adjustment Measures of Vertical Tube Wall

通过对贵州省超临界双拱燃烧锅炉垂直管屏水冷壁结构特点以及运行的安全状况的介绍,针对锅炉热负荷分布、工质流量分配、水冷壁热敏感性、热应力的集中等多个因素,结合实例,对水冷壁运行安全性进行了分析,提出了减少水冷壁爆管的调整措施以及改进的建议,对国内超临界双拱燃烧锅炉的运行调整和进一步的推广应用具有良好的参考作用。

This paper introduced the Guizhou province supercritical combustion characteristics of double arch boiler water wall and the safety of operation condition of boiler, the heat load distribution, flow distribution, water wall heat sensitivity, thermal stress concentration and other factors, combined with the example, the operation safety of the water wall is analyzed, put forward the reduce the water wall tube burst adjustment measures and recommendations for improvement, the domestic supercritical double arch boiler combustion adjustment and the operation of the application has a good reference.
