摘要
快速流态化是介于密相流态化与稀相输送之间的操作区域.对于密相流化床内的传热研究,前人已提出许多模型和经验关联式.
This paper presents a study on heat transfer between immersed surface and suspension in a fast fluidized bed 186mm in inside diameter and 8m in height. The results show that heat transfer coefficient in fast fluidized bed increases with increasing solid recirculating rate and decreases with increasing superficial gas velocity, furthermore it decreases along bed height corresponding to the change of the solid concentration.
