How does air injected into a blast furnace help reduce the iron ore in the form of iron oxide, into elemental iron?

Solution

Air Products offers a range of gas-based technologies and a full line of industrial gases, including oxygen and nitrogen to assist with your blast furnace operation. Oxygen can be injected into the blast furnace to improve combustion and facilitate the supplemental injection of pulverized coal or natural gas to reduce coke costs. We can also supply nitrogen to help you safely and effectively blowdown your furnace. The best solution for your process depends on many factors, such as your existing blast furnace’s operating parameters, coke costs, and production goals.

Nitrogen

Oxygen

Oxygen is required for any combustion process. By supplementing or replacing combustion air with oxygen, overall combustion can be improved through increased heat transfer, higher flame temperatures and reduced volume of flue gases. Oxygen can be injected into the blast furnace to improve combustion and facilitate the supplemental injection of pulverized coal or natural gas to reduce coke costs. Oxygen can be supplied from a dedicated plant located at or near a your facility. Or, we can supplement your existing supply with a bulk supply of liquid oxygen delivered by truck. We can help you optimize oxygen usage for your blast furnace operation and can provide you with the most economical mode of supply based on your consumption patterns.

During the blowdown of a blast furnace, nitrogen can safely cool the furnace and suppress combustion.
