Blast furnace injection for minimizing the coke rate and CO₂ emissions

The tuyère injection is one of the key tools to exhaust the blast furnace potential and to minimize its CO2 emissions. The review argues theoretical basis and operation strategies for ensuring the high efficiency of injection of auxiliary reducing agents (ARA). First, it provides the theoretical analysis of requirements that ensure minimum coke and carbon rates, and minimum CO2 emissions. Then it focuses on the injection of selected ARA, such as...
