METHOD AND APPARATUS FOR PROVIDING A GAS SEAL IN A RETURN DUCT AND/OR CONTROLLING THE CIRCULATING MASS FLOW IN A CIRCULATING FLUIDIZED BED REACTOR

摘要

Providing method and the CFB reactors of device air seal have vertical, slot-shaped reflux line (16), and for adjusting in flow circuit block. The reflux line for two different regulatory regions that annular gas seals (22) arrangement is formed in barrier tool (22,24,26) slows down flow circuit quality, by regulatory region. The circulation quality of the process, by adjusting injection fluidizing gas by the adjustment region of region (56,58,60).
