旋风分离器是循环流化床锅炉的重要部件,分离器的分离效率直接关系到锅炉的安全经济运行。旋风分离器中心筒下移,形成密封间隙,造成气体短路引起分离器分离效率下降,锅炉某些特定的运行参数发生了变化,影响了锅炉的安全经济运行。针对这些问题,分析了原因,并采取了一系列措施,取得了一定的效果。 Cyclone separator is an important part of circulating fluidized bed boiler, separator separation efficiency is directly related to the safe and economical operation of the boiler. The cyclone separator moves downward to form a seal gap, resulting in a decrease of separation efficiency due to gas short circuit. Some specific operating parameters of the boiler have changed, affecting the safe and economical operation of the boiler. In response to these problems, the reasons were analyzed and a series of measures were taken to obtain some results.
