Oxygen-Enriched/Oxyfuel Combustion
Oxygen-enriched combustion is a high-efficiency enhanced combustion technology using oxygen-enriched air with an oxygen volume content exceeding 21% as the combustion gas. It can not only significantly enhance the combustion efficiency and flame temperature, reduce the ignition point of the fuels, accelerate the combustion reaction speed, and consequently save the primary energy, but also can promote complete combustion, minimize the amount of flue gases after combustion, improve heat utilization, lower the excess air coefficient, decrease the generation of hazardous substances, and be conducive to CO2 capture. With the progress of combustion technologies and the reduction of oxygen costs, oxygen-enriched combustion technology is increasingly widely used in fields including iron and steel smelting, non-ferrous metallurgy, industrial kilns, thermal engineering, environmental protection, etc.
