Abstract
This article describes technical innovations developed to provide additional heat for the Vanyukov furnaces at the Balkhash Copper Smelter in order to maintain the necessary temperature when there is not enough sulfur in the copper concentrate. The problem was solved by installing two oxy-oil heaters on each furnace. The heaters were installed in the side wall of the furnaces above the slag bath. Oil consumption per furnace is 500–1200 kg/h. The article reports the results obtained from the introduction of these heaters at the Balkhash Copper Smelter.
