PCT No. PCT/EP89/00409 Sec. 371 Date Nov. 26, 1990 Sec. 102(e) Date Nov. 26, 1990 PCT Filed Apr. 15, 1989 PCT Pub. No. WO89/10516 PCT Pub. Date Nov. 2, 1989.In known separators, some of the solids trapped in the trapping chutes may be prevented from being discharged at the wall due to by-pass currents at the lower end of the trapping chutes. To improve the discharge of the separated dust, the lower end of each trapping chute that is adjacent to the wall is provided with an outlet channel piece extending to the wall and having a slot-like outlet opening resting at the wall and opening downward; and sheet metal deflectors are arranged between the outlet channel pieces of each layer of trapping chutes at a distance from each other and from the wall, which form between them delimit slots for the passage of gas. The separator is preferably used to separate solids from the ascending flue gas in a fluidized bed furnace. |
