Sinter Plant Gas Injection

Primetals Technologies is committed to providing innovative solutions that enhance the efficiency and sustainability of the iron and steel production process. The gas injection solutions for coke reduction in sinter plants exemplify this commitment, offering a cutting-edge approach to reducing coke consumption and minimizing environmental impact. Coke is a critical component in the sintering process, serving as a fuel and reducing agent; however, its use contributes to significant CO₂ emissions and operational costs. Gas injection solutions from Primetals Technologies are designed to address these challenges by reducing reliance on coke and optimizing the sintering process.

Gas injection technology is used to introduce alternative gases such as natural gas, blast furnace gas or other hydrogen-containing gases into the sintering bed. This process helps partially replace coke, resulting in reduced coke consumption and lower CO₂ emissions. One of the key advantages of gas injection solutions designed by Primetals Technologies is their ability to enhance the efficiency of the sintering process. By precisely controlling the injection of gases, optimal combustion and heat distribution within the sinter bed are ensured. These gas injection solutions are designed to be flexible and adaptable, allowing for easy integration into existing sinter plant operations. The system can be implemented as a standalone solution or in combination with a Waste Gas Recirculation (WGR) system.

By reducing coke consumption and CO₂ emissions, Primetals Technologies helps plant operators meet their environmental targets and contributes to a more sustainable steel industry. The solutions are also designed to be cost-effective, providing a quick return on investment and long-term operational savings. Primetals Technologies is dedicated to driving innovation in the steel industry. The gas injection solutions for coke reduction in sinter plants are just one example of how Primetals Technologies helps customers achieve their goals with greater efficiency and sustainability.
