It is a big issue that feed materials can be diffused timely throughout the cross-sectional bed and mixed uniformly in the dense zone, which is directly related to the safety, economy and high efficiency operation of large scale circulating fluidized bed (CFB) boilers. The boilers'operation parameters and structure figures, and the physical features of feed materials directly affect the diffusion and mixing of feed materials in the dense zone of CFB boilers.
Cold experiments were conducted in cold-test ...
