PROBLEM TO BE SOLVED: To provide a fluidized medium circulating device which can prevent the unnecessary combustion of a combustible gas in a gasifying furnace caused by leaked-in air and, in addition, has a very small possibility of causing the leakage of a produced gas in the gasifying furnace. SOLUTION: This fluidized medium circulating device recycles a fluidized medium to the fluidized bed gasifying furnace 1 by extracting the medium from the bottom of the furnace 1, and dropping the medium in the furnace 1 through a chute 13 after carrying the medium to a position above the furnace 1. The device supplies the fluidized medium to the furnace 1 together with refuse 2 by supplying the medium to the upstream side of the supplying section (sealing device 3) of the refuse 2. |
