FLUIDIZED GASSIFYING/MELTING APPARATUS, AND METHOD THEREOF

Japanese Patent JP3836582

B2

PROBLEM TO BE SOLVED: To improve the function of a fluidized bed gassifying/melting system for a combustible substance contained in various wastes such as municipal waste and/or industrial waste, and hence ensure stable operation.
SOLUTION: Gas produced by thermally decomposing waste in a fluidized bed gassifying furnace 2 using a fluid medium is combusted in a combustion furnace 45, and resulting combustion gas is used to heat exchange with a heat exchange medium in an independent superheater 26, and then recirculation gas 19 after the heat exchange is used as a fluidizing fluid 13 of the fluid medium in the fluidized bed gassifying furnace 2. Thus, single operation is ensured in a state where the fluidized bed gassifying furnace 2 is separated from a melting furnace 4 and a heat recovery apparatus 5, and even when the operation of the fluidized bed gassifying furnace 2 or the succeeding melting furnace 4, etc., are interrupted for the purpose of maintenance or failure, the system including a fluidized bed gassifying furnace 2 system and the system including the melting furnace 4 and the heat recovery apparatus 5 are ensured to be single operated (warm-up operation). Thus, there is ensured a desirable state of the fluidized bed gassifying furnace 2 and the melting furnace 4 where temperature lowering due to the operation interruption should be avoided.
