METHOD OF SETTING FURNACE FOR BURNING SOLID FUEL INTO WORKING REGIME Russian patent published in 1994 - IPC

Abstract RU 2022224 C1

FIELD: burning engineering. SUBSTANCE: method includes drying and heating lining and filling furnace with melt. Filling the bath with liquid melt is implemented by fusing of low-melting ferrum containing material with sandstone and limestone adders. Burning of fuel is performed through lances with oxygen excess in blasting that is equal to 0.9-0.95. Ferrum ore or concentrate is used as low-melting ferrum containing material. From the moment of the beginning of active barbotage up to beginning of continuous bypassing of melt through siphon sandstone of 20-40% by mass is added. After that supplying of fuel into the lances stops. Feeding of sandstone is also stops. Solid fuel is charged through charging units of top of the furnace and 15-55% of limestone is fed. EFFECT: simplified method. 3 cl
