Abstract
A surge feeder for feeding refuse material into a furnace comprises a plurality of rollers mounted on a base supporting the rollers above the feed opening to the furnace. A chain and sprocket drive mechanism is mounted to the base and serves to counter-rotatably drive the rollers. Each roller has fixedly mounted thereto at equally angularly spaced apart locations a plurality of generally planar shaped paddles which extend continuously along the length of the roller. The paddles project radially from and alternate in height angularly about each roller.
