METHOD FOR UTILIZATION OF OILY FURNACE CLINKER FINES Russian patent published in 2004 - IPC

Abstract RU 2241762 C1

FIELD: iron metallurgy, in particular blast-furnace industry and method for recycling of oily rolled furnace clinker.

SUBSTANCE: wet fine furnace clinker is mixed with liquid hydrocarbons (e.g. exhaust motor oil, and/or petroleum product waste, and/or exhaust transformer oil, and/or liquid by-product-coking waste, and/or aqueous waste fouled by petroleum products). Mixture is fed to emulsifier to obtain stable water-dispersed fuel, which is heated to 50-900C and fed into furnace blast for injection into blower nozzle under pressure higher than that of hot blasting by 50-250 kPa. Ratio of furnace clinker, water and liquid hydrocarbons is (30-60):(15-30):(25-50), respectively.

EFFECT: reduced coke and raw agglomerate consumption in furnace-blast smelting.
