Effect of temperature and gas velocity distribution on the fluidization of the sticky particles

We have constructed a 15 cm ID visually observable fluidized bed to obtain information about the fluidized bed under agglomerating conditions and study the effect of gas distribution and temperature variation on the rate and extent of agglomeration. The gas distributors consist of porous cones and a central jet. The temperature distribution and extent of agglomeration were measured at different operating conditions. Jet height, fluidizing air temperatures, and proper gas distribution can enhance the agglomeration of the sticky particles in the fluidized bed without causing detrimental sintering. 6 refs., 5 figs., 1 tab.
