Abstract
An improved grate construction for a fixed bed coal gasifier comprises an interrupted generally cylindrical platform including a plurality of sector-like portions and rotatable means, e.g. a stirrer, mounted for rotation adjacent the upper surface of each platform portion. The upper surface of each portion is inclined upwardly in a circumferential direction to an upper leading edge thereof from which an upright wall depends. The stirrer is rotated in the opposite circumferential direction for cooperating with the depending walls to reduce the size of clinkers and for promoting movement of solids from the shaft over the platform.
