Abstract
PURPOSE: To stabilize the pyrolysis of a solid waste, e.g., municipal waste, etc., by detecting physical and chemical amounts of a fluid medium so that the fluid medium and the pyrolysis temperature are controlled stably, in pyrolyzing the solid waste using a fluidized bed pyrolysis column and a fluidized bed combustion column.
CONSTITUTION: A fluid heating medium, e.g., sand, etc. is circulated between the fluidized bed pyrolysis column 1 and the fluidized bed combustion column 2, and a formed gas is partially recycled as a fluidizing gas through the column 1. A solid waste, e.g., municipal waste, etc. is fed from the silo 4 to the pyrolysis fluidized bed 8 and gasified to a formed gas which is recovered as a fuel. The heating medium with its temperature lowered by the endothermic reaction of pyrolysis accompained by a formed char ingredient is sent to the lifting part 7 of the combustion column and the fluidized bed 11 of the combustion column where the char ingredient burns completely to raise the temperature of the heating medium. The formed gas and the exhaust gas of the columns 1 and 2 are subjected to heat exchange with the circulating gas, etc. and the impurities at the bottom of the columns are discharged. An amount of the circulating sand is given dependently upon a feed rate of the raw material, its water content, and the energy balance resulting from the temperature conditions of both the columns, and amounts of the lifting air and the circulating gas are selected so that the pyrolysis is stabilized.
