Embodiment Construction

[0021] refer to figure 1 , a charging machine 10 for a coke oven is provided here. The loader includes a compacted coal bunker 12 and an uncompacted coal bunker 14 . Coal is supplied to both the compacted coal bunker and the uncompacted coal bunker by means of transverse conveyors 16 for conveying the coal from the coal source to the filling chute 18 and into the coal charging bunker 20 . The coal loading cabin 20 preferably includes leveling means, such as a chain leveling system 22, for spreading coal 24, preferably uncompacted coal, into the coal loading cabin 20. The coal loading bunker 20 is supported above the compacted coal bunker 12 and the uncompacted coal bunker 14 by respective support beams 26 .

[0022] The coal flows through two or more discharge chutes 30 to accumulate on the packing plate 28 and in the uncompacted coal bunker 14 . Each discharge chute 30 is preferably a pyramidal discharge chute with flanged outlets 32 provided therewith. Each discharge val...

Abstract

The invention provides a coke oven charging machine including a mobile frame and a coke oven feed device on the mobile frame. The coke oven feed device includes a movable, elongate charging plate having a first end and a second end, retractable side-walls adjacent the charging plate, first and second end walls adjacent the first and second ends of the charging plate and a shuttle section adjacent the first end of the charging plate for spanning an area between the first end of the charging plate and an entrance to the oven. The shuttle section has opposed shuttle side walls and a shuttle end wall. A charging plate moving device is provided for moving the charging plate into and out of the oven. The charging machine apparatus provides a means for quickly charging coking ovens with a compacted coal charge so that lower quality coals may be used to make metallurgical coke.

Description

technical field [0001] This invention relates to a method and apparatus for making coke from coal, and more particularly to a method and apparatus for compacting and feeding coal to a non-recovery coke oven. Background technique [0002] Coke is a solid carbon fuel and carbon source used to melt and reduce iron ore in the production of steel. In one iron-making process, iron ore, coke, hot air, and limestone or some other flux are fed into a blast furnace. The hot air causes the coke to burn, providing heat and a carbon source for the reduction of iron oxides to iron. Limestone or other fluxes may be added to react with and remove various acidic impurities called slag from the molten iron. Limestone, an impurity, floats to the top of the molten iron and is skimmed off. [0003] In a process known as Thomson coking, coke used to refine metal ores is produced by feeding pulverized coal in batches to sealed and heated to very high temperatures of 24 to 24 48 hours in one fu...
