Development of Oxygen-rich Furnace System for reduced CO2 and NOx emissions
The purpose of this work was to develop an O2-enriched furnace system that will reduce CO2 and NOx emissions under typical steel industry operating conditions. The combination of the latest burner technology for air-fuel combustion with O2-enrichment should result in both lower NOx and CO2 emissions. A modification to an ultra-low-NOx burner design to accommodate O2-enriched combustion was made and installed in a pilot reheat furnace. The burner was tested and optimized within its range of operating configurations.

Development of Oxygen-rich Furnace System for reduced CO2 and NOx emissionsCosts & Benefits
| Parent Process: Rolling Mills | |
|---|---|
| Energy Savings Potential |
By applying this technology, fuel firing rate was decreased from 325-365 KW to 200-220 KW. |
| CO2 Emission Reduction Potential |
Potential savings are 40 – 45% in fuel usage. A corresponding reduction in CO2 emissions is obvious. |
| Costs |
Fuel savings are offset to some extent by the cost of the Oxygen. However O2 production technologies are becoming more economical. |
