目前大多数循环流化床锅炉都以一个或几十大型旋风子作为固体颗粒分离装置。旋风子通常与锅炉本体分离,通过固体颗粒回料管与炉膛相接。以往,旋风子及其外壳都以耐火材料衬里。随着机组容量及锅炉尺寸的增大。这种结构设计逐步被部分或全部水冷(或汽冷)的旋风子所取代。这代表了循环 At present, most circulating fluidized bed boilers use one or dozens of large cyclones as the solid particle separation device. The cyclones are usually separated from the boiler body and connected to the hearth through the solid particles return pipe. In the past, Cyclones and their housings were lined with refractory materials. With the unit capacity and boiler size increases. This structural design is gradually replaced by some or all of the water-cooled (or air-cooled) cyclones. This represents a loop
