FINE SOLIDS RECYCLE IN A CIRCULATING FLUIDIZED BED |
摘要 |
A CFB furnace or reactor unit is provided having enhanced circulation of the reagents finest particles. The improved circulation is achieved by recycling gas havi ng entrained fine particles from a solids collection hopper connected to the solids separator back into the reactor. A system of one or more conduits connects the upper portion of the solids collection hopper with the reactor. The conduit system is equipped with means for recycling gas fro m the hopper to the reactor. The invention is an inexpensive system which permits recycling of t he finest particles that would otherwise be carried over with the gas flow exiting the separator .
