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.

Improved Hot Stove Process ControlCosts & Benefits

Parent Process: Blast Furnace System
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

US flag Emissions can be reduced by 22.6 Kg CO2/t-HM (US EPA, 2010. p.9).

Costs

US flag Retrofit capital cost is estimated to be US $0.47/t-HM. The payback times are around 4 months (US EPA, 2010. p.20).
