65t/h煤粉炉改造为65t/h循环流化床锅炉后锅炉结焦和布风板严重变形等一系列技术问题进行了分析,提出了再改进措施,如改进破碎系统、将风冷布风板改为水冷水冷布风板、将圆柱式风帽改为钟罩式风帽、将原埋管防磨护瓦由吊挂在埋管上改为直接焊在埋管上等,取得较为明显的效果。为煤粉炉改造成循环流化床锅炉的设计、设备选型及运行提供技术借鉴。
65t / h pulverized coal fired boiler retrofitted to a 65t / h circulating fluidized bed boiler after the boiler coking and a serious deformation of the air distribution board and a series of technical problems were analyzed, and then proposed further improvements, such as improving the crushing system, To water-cooled water-cooled cloth plate, the cylinder-style hood to the bell-style hood, the original buried wear-resistant tile from hanging pipe buried in the tube instead of welding directly to achieve more obvious results. To provide a technical reference for the design, equipment selection and operation of a pulverized coal fired boiler retrofitted into a circulating fluidized bed boiler.
