Abstract
The present invention provides a method for dynamically controlling the circulation rate of solids in an interconnected fluidized bed. When an interconnected fluidized bed is operating, it is available to control the circulation rate of solids by adopting the steps of adjusting the height difference between the orifice on the weir and the bottom surface of the bed region, adjusting the cross-sectional area of the above orifice, or adjusting the height of the above weir. By using multiple ways, the circulation rate of solids can be improved substantially. In addition, the curve of circulation rate of solids can be converged to the maximum circulation rate of solids effectively.
