Oxygen-enriched burners are commonly used in industrial fields and can provide higher combustion efficiency and lower emissions during the combustion process. This type of burner usually uses pure oxygen or high-concentration oxygen instead of air as an oxidant, thereby making the combustion process more complete and efficient. Oxygen-enriched burners are widely used in some industrial production processes that require high temperature and high efficiency, such as glass production, metal smelting and other fields.
