Oxy-Oil Injection

Oxy-oil burners are installed at all tuyeres designed for the use of heavy oil only. Oil and oxygen is separately fed and the oil must be preheated upto 220 °C. The amount of oxygen enrichment is 7-9%. With oxy-oil injection technology, the amount of oil-injection doubles. In practice, oxy-oil injection works very reliably.

Oxy-Oil InjectionCosts & Benefits

Parent Process: Blast Furnace System
Energy Savings Potential

Up to 130 kg/t hot metal Oxy-Oil Injection is applied. The savings of coke is thus about 15 kg/t hot metal.
CO2 Emission Reduction Potential

Reduction in CO2 emissions is roughly 50 kg/t hot metal.
Costs

Additonal costs will arise for air enrichment to provide constant huge amounts of Oxygen and additional requirement of injection unit maintenance.
