Abstract

A.LE PROCEDE EST DESTINE AU TRAITEMENT DE CHARBON FIN, EN NOIX, BRIQUETTES, QUE L'ON DESIRE ENTREPOSER EN UN TAS IMPORTANT, APRES L'AVOIR ENTASSE PAR COUCHES. B.ON ARROSE CHAQUE COUCHE, AVANT DE LA COMPACTER, AVEC UNE SOLUTION AQUEUSE DE CHLORURE ALCALINO-TERREUX CONTENANT UN AGENT MOUILLANT. C.LE CHARBON AINSI TRAITE ET COMPACTE EST TRES BIEN PROTEGE CONTRE TOUT RISQUE D'INFLAMMATION SPONTANEE ET CONTRE LES PERTES DE POUVOIR CALORIFIQUE, CE QUI PERMET DE LE CONSERVER EN STOCK PENDANT UNE LONGUE DUREE.A. THE PROCESS IS INTENDED FOR THE TREATMENT OF FINE COAL, IN WALNUTS, BRIQUETTES, WHICH IT IS DESIRED TO STORE IN A LARGE BATCH, AFTER HAS BEING PACKED BY LAYERS. B. WATER EACH LAYER BEFORE COMPACTING IT WITH AN AQUEOUS ALKALINE-EARTH CHLORIDE SOLUTION CONTAINING A WETTING AGENT. C. THE CARBON THUS TREATED AND COMPACT IS VERY WELL PROTECTED AGAINST ALL RISKS OF SPONTANEOUS IGNITION AND AGAINST LOSS OF HEAT POWER, WHICH ALLOWS IT TO BE KEPT IN STOCK FOR A LONG TERM.
