Title:
FLUIDIZED-BED APPARATUS
Document Type and Number:
Japanese Patent JP3402962
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To cool fluidized-bed ash and simultaneously preheat fluidized gas by supplying gas below a grating disposed at a downstream of an extraction tube in a fluidized-bed container to receive fluidized-bed ash discharged via the tube.
SOLUTION: This apparatus comprises a fluidized-bed 3 in a fluidized-bed container 1 to discharge fluidized-bed ash generated on a fluidized-bed 3 down via an extraction tube 4. In this case, a gas introducing tube 9 provided at the container 1 supplies gas under a grating 11 installed at a downstream of the tube 4 in the container 1 to receive the ash discharged via the tube 4 to cool the ash on the grating 11.
