介绍了新投运的燃烧福建无烟煤的循环流化床锅炉 ( CFB锅炉 )的设计特点 :采取了敷设长卫燃带、蒸发受热面布置于炉膛出口 ,增强抗磨损能力等 ,并对分离器的回料温度、返料点和返料量等设计不足进行了分析。工业实验结果显示 ,燃烧福建无烟煤的 3 5 t/h循环流化床锅炉 ,炉内添加石灰石的脱硫工艺是可行的。在 Ca/S比取 2 .5～ 3 .0、石灰石平均颗粒径取 0 .2～ 1 .0 mm时 ,可以取得较佳的脱硫运行效益 Introduced the new investment of Fujian anthracite circulating fluidized bed boiler (CFB boiler) design features: take the laying of long Wei burning zone, evaporation heating surface arranged in the furnace outlet, enhanced anti-wear capacity, and the separator Back to the material temperature, return points and the amount of material back to the lack of design were analyzed. The results of industrial experiments show that it is feasible to use 35 kt / h circulating fluidized bed boiler to burn Fujian anthracite and limestone desulfurization process in the furnace. In the Ca / S ratio of 2.5 ~ 3.0, limestone average particle size of 0. 2 ~ 1 .0 mm, you can get better desulfurization operating efficiency
