Pollution-control continues to be a process and production-cost consideration for iron and steel foundries around the world, due to the preponderance of coke as a fuel for cupola melting. Among the different forms of cupolas available to foundries, the “cokeless” cupola reduces emissions of carbon dioxide (CO2) by 75-80% compared with coke-fired cupolas, and produces the least volume of furnace dust, at 100-120 kg of CO2 and 0.8 kg of dust per metric ton of melt.
