Title:
MULTICHAMBER DIVISION TYPE FLUIDIZED BED FURNACE
Document Type and Number:
WIPO Patent Application WO/1999/042777
Kind Code:
A1
Abstract:
A fluidized bed furnace in which the height difference between the fluidized beds of the front and rear divided chambers is appropriate and does not cause back mixing. When the vertical position of the communication port (9) for moving the material from the upstream-side divided chamber to the downstream-side divided chamber is 1/4 the height of a fluidized bed, the length of the communication port (9) is more than 100 mm, and the gas nozzle is directed almost vertically upward, arrangements are made so that the distance (x) from the inlet of the communication port (9) to the end face of the upstream-side nozzle is larger than 150 mm, that the distance (x) from the outlet of the communication port (9) to the end face of the downstream-side nozzle is larger than 50 mm, and that in both the upstream-side and downstream-side closed portions of the communication port (9), an angle formed with respect to the horizontal plane by a line connecting the corner of the upper surface of the communication port and the gas blowout opening is set larger than the angle of repose of the powder material.
