In a calcium carbide furnace, the chemical reaction is generally understood to occur in a zone around and below the electrode tip. It is thought that this zone is a packed bed of coke with its voids filled by molten calcium carbide and evolving reaction gas. The calcium carbide drains to the furnace hearth from where it is tapped adjacent to the electrode, while the gas percolates up out of the reaction zone and through the overburden into the furnace freeboard. As the reac-tion proceeds and calcium carbide is tapped, fresh charge mix descends into the reaction zone from the choke fed bed of charge above. The energy driving the endothermic calcium carbide production …
