PURPOSE:To safely operate a graphitizing furnace by introducing cyanides such as cyanide or hydrogen cyanide, if produced in a graphitizing furnace using nitrogen gas, into an oxidizing atmosphere at 200-500 deg.C, decomposing and removing the cyanides. CONSTITUTION:A waste gas, produced in a graphitizing furnace and containing cyanides is introduced through a discharge conduit into a waste gas converter of an oxidizing atmosphere at 200-500 deg.C. Air is simultaneously introduced through a conduit into the waste gas converter. Thereby, the cyanides in the waste gas are then decomposed and removed by the waste gas converter. |
