脱硫剤の供給装置。[Claims for Utility Model Registration] 1. A fluidized bed equipped with a fluidized bed that performs fluidized combustion by fluidizing fuel together with a fluidized medium using fluidizing air, and a desulfurizing agent supply device that performs desulfurization by adding a desulfurizing agent to the fluidized bed. In the bed combustion furnace, the desulfurization agent supply device is provided with a desulfurization agent supply bunker that individually supplies two or more types of desulfurization agents to the fluidized bed combustion furnace, and the desulfurization agent supply bunker is configured to supply desulfurization agents that are difficult to powder. at least one desulfurizing agent supply bunker that supplies an inert granular agent that is difficult to powder to the fluidized bed as a fluidized medium; 1. A desulfurizing agent supply device comprising at least one desulfurizing agent supplying bunker for supplying the desulfurizing agent to the top of the bed, or within the fluidized bed and to the top of the fluidized bed. 2 The desulfurizing agent supply pipes that supply the desulfurizing agent from each desulfurizing agent supply bunker to the fluidized bed combustion furnace may be connected to the fluidized bed combustion furnace individually, or may be connected to the fuel supply pipe. 2. The desulfurizing agent supply device according to claim 1, which is characterized in that the desulfurizing agent supply pipes are partially or entirely connected to each other. 3. The desulfurizing agent supply device according to claim 1 or 2 of the utility model registration claim, wherein the desulfurizing agent is limestone.
