Abstract

A coal compaction system and method for a non-recovery coke oven having refractory roof, floor, side walls and end doors for coal charging and coke discharge provides an improved coal charging machine carrying a coal conveyor supported intermediate the ends of the conveyor to avoid conveyor sagging and non-uniform depth of a deposited coal bed, a number of pressurized fluid-driven vibratory compactors mounted on an end of the charging machine and spaced-apart across the width of the coal bed and serving to compact the coal bed on a retraction stroke of the charging machine, a pivoted lifting frame mounted on the charging machine above the compactors and from which the compactors individually are suspended and are provided with individual supply of pressurized fluid, and a coke pusher head mounted on the charging machine behind the compactors and serving, when the lifting frame and associated compactors are raised, to push finished coke from the coke oven.
