FIELD: metallurgy; heat engineering; metallurgical and engineering plants for production of metalware, zinc-coated wire, for example. SUBSTANCE: proposed furnace has bath filled with melt, prechamber partially divided in height by burners and nozzles into parallel zones of incomplete combustion of fuel with burners and afterburning of incomplete combustion products with secondary air nozzles, recuperator mounted under main roof of prechamber in area of afterburning of incomplete combustion products. Heating of air and final afterburning of incomplete combustion products will be performed simultaneously under prechamber roof. EFFECT: enhanced efficiency of furnace; reduction of oxidation of melt due to increased temperature of heating air fed for combustion. 3 cl, 3 dwg
