2009年9月对陕西延安某DGJ240/9.8-112型循环流化床锅炉进行了首次全面检验,发现炉膛过渡区前墙、侧墙水冷壁有较严重的冲蚀磨损。本文从磨损部位的几何结构、入炉固体颗粒粒径、锅炉运行三方面分析了磨损原因,并从设计、安装、运行和检修等方面提出建议。1锅炉参数及冲蚀磨损情况1,1锅炉相关参数(见表1)
In September 2009, the first comprehensive test was conducted on a DGJ240 / 9.8-112 circulating fluidized bed boiler in Yan’an, Shaanxi Province. It was found that the water wall of the front wall and the side wall of the furnace transition zone had more serious erosion and wear. In this paper, the causes of wear are analyzed from three aspects: the geometric structure of the worn parts, the diameter of the solid particles into the furnace and the operation of the boiler, and the suggestions are put forward from the aspects of design, installation, operation and maintenance. 1 boiler parameters and erosion wear 1 boiler-related parameters (see Table 1)
