METHOD FOR THE COLLECTION AND TREATMENT OF REACTION GASES OF A Fused METAL PRODUCTION INSTALLATION, AND A DUST ELIMINATOR INSTALLATION FOR SUCH PURPOSE.

摘要

Method for the operation of a dust removal facility, according to claim 9, for the collection and treatment of reaction gases of a molten metal production facility, wherein metaliferous application substances are introduced into a metallurgical container solid or liquid form, and said substances react under the action of fuels and reaction materials, and the hot, gaseous and dust-laden reaction gases, which leave the metallurgical vessel, are partially supplied to a primary process of dust removal and partially to a secondary dust removal process, in assigned dust separating devices (11), characterized in that the reaction gases supplied to the secondary dust removal process circulate through a thermal accumulator (9) before the secondary elimination process of dust, and the heat of the reaction gases is supplied to the thermal accumulator, with a temperature of the reaction gas that is above the temperature of the wall of the accumulator elements, and said accumulated heat is again supplied to the following reaction gases with a temperature of the reaction gas that is found by below the wall temperature of the accumulator elements.
