Recuperative BurnersCosts & Benefits
|Parent Process: Rolling Mills|
|Energy Savings Potential||
Recuperative burners in the reheating furnace can reduce energy consumption by as much as 30 percent. Although actual savings will be highly facility-specific, one estimate placed energy savings at approximately 0.7 GJ/t-product.
tIn a US based plant, recuparator replacement reduced fuel consumption by 9%.
Another example in Japan shows that a newer model continuous slab reheating furnace can reduce energy consumption by 25% in comparison to an older furnaces recovering waste heat with a recuperator.
|CO2 Emission Reduction Potential||
tEmission reduction estimations are in 35.2 kg CO2/t-steel.
Retrofit Capital Cost is $3.9/tonne rolled steel.
