A plant for producing calcium carbide

摘要

A burden of either or both CaO or CaCO3 and coal is melted and reduced by a plasma torch established between a plasma burner penetrating the upper structure of a furnace and an electrode in the bottom of the furnace to produce CaC2. The burden is supplied to the furnace from above and the CO produced by the reaction flows upwardly through the unreacted burden to pre-heat and pre-reduce it.
