The U.S. Environmental Protection Agency’s (EPA) energy guide, Energy Efficiency Improvement and Cost Saving Opportunities for the U.S. Iron and Steel Industry, discusses energy efficiency practices and technologies that can be implemented in iron and steel manufacturing plants. This guide provides current real world examples of iron and steel plants saving energy and reducing cost and carbon dioxide emissions.
Improved Hot Stove Process Control
Automated operation of the hot stoves can help maintain optimal conditions thereby reducing energy consumption of the stoves, increasing the reliability of their operation, and enhancing the stove lifetime.
This measure is regarded to have high application potential in China, India and the United States. However, in most cases the blast furnace design, lack of necessary hardware for better control plus cost of control system can act as a limitation for the use of modern, computer based control systems.

Energy Savings Potential |
Energy savings typically range between 5 and 12%, and may reach 17%. Typically, this may equate to 0.037 GJ/t-HM (US EPA, 2010. p.20). |
CO2 Emission Reduction Potential |
Emissions can be reduced by 22.6 Kg CO2/t-HM (US EPA, 2010. p.9). |
Costs |
Retrofit capital cost is estimated to be US $0.47/t-HM. The payback times are around 4 months (US EPA, 2010. p.20). |
