循环流化床锅炉与煤粉锅炉相比,没有那种复杂的制粉系统,节省了大量投资。与普通流化床锅炉相比,循环流化床通过分离回送机构,将没燃尽的细物料送回沸腾床循环燃烧,使机械不完全燃烧损失大大低于普通流化床锅炉,其锅炉效率可与同类煤粉炉相比。同时流化床锅炉因其分离器所处位置不同分为外循环流化床锅炉和内循环流化床锅炉;根据炉膛流速不同分为高速流化床和低速流化 Circulating fluidized bed boilers, compared with pulverized coal boilers, do not have that sophisticated milling system and save significant investment. Compared with the ordinary fluidized bed boiler, circulating fluidized bed through the separation of the loop back to the body will not burn the fine material sent back to the ebullated bed cycle combustion, the mechanical loss of combustion is substantially lower than the ordinary fluidized bed boiler, the boiler efficiency Compared with similar pulverized coal stoves. At the same time, the fluidized bed boiler is divided into outer circulating fluidized bed boiler and internal circulating fluidized bed boiler because of the location of its separator. According to the different furnace velocity, it is divided into high speed fluidized bed and low speed fluidized bed
