Oxygen is a necessary element in the combustion process. Increasing the oxygen concentration in the boiler can make the fuel burn more fully, thereby improving the combustion efficiency. By injecting air or pure oxygen into the furnace, an oxygen-rich zone is formed near the flame, thereby improving the combustion efficiency and output. This method is simple and easy, but it is necessary to control the injection speed and amount to avoid excessive flame temperature or oxygen waste. Boiler oxygenation technology is widely used in industrial production, such as electricity, chemical, petrochemical, steel and other fields. In the power industry, boiler oxygenation can improve the fuel utilization rate of thermal power plants.
