摘要：

An attempt is made to develop an equation for calculating heat transfer coefficient in a cocurrent gas-solid flow circulating fluidized bed. The gluidized bed is considered to consist of clusters and bubbles. It is shown that the heat transfer coefficient is a function of gas and solid flow rates as well as bed density. The transfer coefficient is independent of particle size and decrease with increase in column diameter.
