Abstract

Innovative blast furnace operations with top gas recycling after CO2 scrubbing were numerically examined. The fully kinetic mathematical model was applied to the operations with recycled gas injections into the tuyere and stack parts of the furnace, and the top gas recycling combined with waste plastics injection. The simulation results showed that the top gas recycling decreased the reducing agent rate and increased the productivity.
