Horizontal coke oven charging system - involves introducing inert gas into coke oven gases to dilute them to safe concn

Method is described for charging a coke oven battery whose coking chambers each have at least three charging holes. Coal is charged into a coking chamber through its extreme charging holes whilst simultaneously withdrawing gases through a middle charging hole. Subsequently, the charging is completed by charging and into the chamber through the middle charging hole whilst simultaneously withdrawing gases through the same hole. The gases are withdrawn are diluted with inert gaseous diluent constituting 15 to 20% of the total amt. of the gases withdrawn. The method permits the safety of the charging to be improved by withdrawing the coke-oven gases from the charging zone and simultaneously introducing a gas inert to the coke-oven gas in an amt. sufficient to dilute the latter to a safe concn. L'INVENTION CONCERNE L'INDUSTRIE DU CHARBON.LE PROCEDE FAISANT L'OBJET DE L'INVENTION EST CARACTERISE EN CE QUE L'EVACUATION DES GAZ, LORS DU CHARGEMENT DU CHARBON A TRAVERS LES TROUS EXTREMES 9, 10 DU FOUR A COKE S'EFFECTUE A TRAVERS LES TROUS MEDIANS 11 DU MEME FOUR, TANDIS QUE LE CHARGEMENT DE CHARBON A TRAVERS LES TROUS MEDIANS 11 S'EFFECTUE SIMULTANEMENT AVEC L'EVACUATION DES GAZ PAR LES TROUS MEDIANS 11 DU FOUR RECEVANT LE COMPLEMENT DE CHARGE ET AVEC L'AMENEE DANS CE FOUR D'UN GAZ INERTE VIS-A-VIS DU GAZ DE COKERIE, A RAISON DE 15 A 20 DE LA QUANTITE TOTALE DE GAZ DE COKERIE EVACUE.L'INVENTION PEUT ETRE UTILISEE AVEC LE PLUS DE SUCCES POUR LE CHARGEMENT SANS FUMEE DES FOURS A COKE HORIZONTAUX.
