The significance of measuring flue gas oxygen content in boilers

Release time: 2022-12-11


  Flue gas oxygen content is one of the important monitoring parameters for boiler operation and an important basis for reflecting the completeness of boiler operation and combustion equipment. Its value is related to factors such as boiler structure, type and properties of fuel, boiler load, operation air distribution conditions, and equipment sealing conditions. The smaller the oxygen content, the smaller the excess air coefficient, indicating that the heat loss due to incomplete chemical combustion and incomplete mechanical combustion increases; the larger the oxygen content, the larger the excess air coefficient, indicating that too much air is supplied. Excess air causes a decrease in furnace temperature, which not only affects combustion but also carries away a large amount of heat and dust, increasing the calculated results of pollution emission concentration. At the same time, a large air volume also increases the power consumption of exhaust gas. Controlling the flue gas oxygen content is of great significance to controlling the combustion process and achieving safe, efficient, and low-pollution emissions.
