循环流化床锅炉(CFBB)运行中,排渣直接决定着燃烧室的物料浓度,燃烧后的灰渣只有及时排放才能补进新煤以维持能量平衡。而堵渣是循环流化床锅炉最常见的故障现象,是影响循环流化床连续运行的最大障碍之一。针对这一问题,对堵渣原因进行分析研究,提出了切实可行的解决方案,并取得了良好的效果。 During the CFBB operation, the slag discharge directly determines the concentration of the material in the combustion chamber. Only the discharged ash can be discharged into the new coal in time to maintain the energy balance. Blocking slag is the most common failure phenomenon of circulating fluidized bed boilers and is one of the biggest obstacles to the continuous operation of circulating fluidized bed. In response to this problem, analysis of the causes of slag clogging, put forward practical solutions, and achieved good results.
