Abstract
An experimental physical model was set up on the base of the fluidized furnace of a factory. The influence of top gas flow rate and position on gas–solid flow distribution characteristics were analyzed by the experimental comparison in bed. The results were shown that the gas–solid mixture was more homogenous distribution and had less effects from the top gas when the ratio of bed height to diameter was 1.58, the apparent gas velocity was 0.13–0.18 m/s and the continuous charging speed was 360 kg/h. The depth of the top jet had a great effect on the gas–solid flow in the expansion part of a babble fluidized bed . The elutriation and sticking of particles on the wall were decreased with the depth of the position of the jet increasing.
