Installation for the control of solid particle movement in fluidised bed

摘要

A particle movement controller, being disposed between a first fluidised bed, to where particles are supplied, and a second fluidised bed, from where particles are discharged, which controls the moving amount of the particles from the first fluidised bed to the second fluidised bed, is improved to have a substantially proportional characteristic without a hysteresis. Flow rate control nozzle pipes 30a, 30b, ..., 30j made of horizontal pipes are disposed vertically at intervals and nozzle holes 31 are formed in a lower surface of each of the nozzles. An amount of air emitted from each nozzle holes 31 is controlled using opening and closing valves 33a, 33b, ..., 33j or flow rate adjustment valves 35a, 35b, ..., 35j (FIG. 2). <IMAGE> <IMAGE>
