Abstract

A thermal decomposition furnace in which waste tires having original shape, not broken up, can be laid horizontally and be thermally decomposed. The furnace is constructed by providing a feeder above, forming downward a fluidized bed-forming section having inlets for air, forming beneath a sealing bed-forming section of right cylindrical shape having a diameter smaller than that of fluidized bed-forming section, and installing a conveyor below said sealing bed-forming section. At the lower end of sealing bed-forming section, an oblique opening is formed so as to keep a progressively increasing clearance to the conveyor in the direction of advance of conveyor.
