PROBLEM TO BE SOLVED: To provide a refuse feeder for equally distributing and supplying city waste and other waste to treating equipment such as a fluidized gasification furnace, a fluidized incinerator or fluidized thermal decomposition furnace. SOLUTION: This feeder is provided with a refuse supply hopper 12 arranged on a front stage of a gasification furnace 10 such as the fluidized gasification furnace, the fluidized incinerator or the fluidized thermal decomposition furnace, a refuse supply cylinder 16 provided in a lower part of the refuse supply hopper 12, an air-cooled jacket 17 formed on a feeding side of the refuse supply cylinder 16 and a screw conveyor driving mechanism 35, as principal parts. The feeder equally distributes and supplies refuse to be incinerated to the gasification furnace 10 by a screw type conveyor jointly provided with two shafts provided in the refuse supply cylinder 16. A partition plate 23 is erected between screws 20 of two parallel shafts within the refuse supply cylinder 16. The screws 20 of the two shafts are made to have a mutually alienating rotation by reversing the rotation to each other. By mutually shifting screw blades 21 by a 180°phase, refuse is fed from distal end parts 21a of the screw blades 21 rotating in the phase shifted states. COPYRIGHT: (C)2005,JPO&NCIPI
