METHOD FOR RECUPERATING THERMAL ENERGY OF GASES OF AN ELECTROMETALLURGICAL FURNACE AND USE FOR MAKING SILICA POWDER |
摘要 |
The invention concerns a method for recuperating thermal energy of hot gases of a submerged-arc furnace designed to make metal alloys by atomization of a powder from solid particles suspended in an aqueous phase. The solid particles are, preferably, derived from the filtering of gases emitted by the electric furnace. The invention also concerns a method for making silica powder with improved properties from fumes of a silicon or ferro-silicon furnace, which consists in preparing a suspension of said fumes in water and atomizing said suspension. |
