<p>A system for supplying pre-heated coal to a coking oven battery, comprising a conveying section (16, 17, 18, 19), a plurality of storage bunkers (20) for receiving the coal from the conveying section, a plurality of metering bins (22) for receiving the coal from storage bunkers and for transferring same in metered quantities to the coking ovens (24), and an inert gas source (25) adapted to introduce inert gas to the conveying section and the storage bunkers, there being an inert gas reservoir (38) adapted for connection selectively to the inert gas source or to said metering bins, and control valves (37, 40) to permit the reservoir to become charged with inert gas prior to the discharge of coal from the metering bins and to release the gas charge into the metering bins consequent upon the discharge of coal therefrom. <IMAGE></p> |
