DEVICE FOR SUPPLYING FLUIDIZING PARTICLES TO FLUIDIZED BED GASIFYING FURNACE

摘要

PROBLEM TO BE SOLVED: To provide a device for supplying fluidizing particles to a fluidized bed gasifying furnace, capable of preventing outside air from flowing inside the furnace from a casting part of fluidizing particles when casting the fluidizing particles into the fluidized bed gasifying furnace.SOLUTION: A device for supplying fluidizing particles to a fluidized bed gasifying furnace includes: a conveyor casing 443 equipped with a tubular peripheral wall extending from an opening 445a to a particle casting part 17; a screw shaft 444 that can convey the fluidizing particles supplied from the opening 445a by rotation of the conveyor casing in the conveyor casing 443; and a fluidizing particle accumulation part 42 that is deposited at the upper side of the opening 445a and supplies the fluidizing particles filled inside from the opening 445a in the conveyor casing 443 so as to be piled up on the fluidizing particles in the conveyor casing 443. The conveyor casing 443 is tilted so that the particle casting part 17 side becomes an upper position than the opening 445a side.
