Abstract RU 2241929 C1

FIELD: metallurgy; production of melt from mineral raw materials.

SUBSTANCE: the invention is dealt with metallurgy, in particular with production of melt from mineral raw materials. The coke-gas cupola furnace contains a furnace stack, a tap-hole for a melt tapping, lances for an air supply and the gas fuel feeding devices located in one horizontal plane in the interleaving order along the furnace stack perimeter. A device for gas-shaped fuel feeding is made in the form of a gas jet mounted in an air lance. The invention allows to increase significantly reliability of the coke-gas cupola furnaces operation, to reduce consumption of the technological fuel.

EFFECT: the invention allows to increase significantly reliability of the coke-gas cupola furnaces operation, to reduce consumption of the technological fuel.
