Zirconia oxygen analyzer BW3000

       Zirconia oxygen analyzers are mainly used for measuring the oxygen content in boiler flue gas. Flue gas oxygen content is one of the important monitoring parameters for boiler operation and an important basis for reflecting the completeness of the operation of combustion equipment and boilers. Its value is related to factors such as boiler structure, type and properties of fuel, boiler load, operating air distribution conditions, and equipment sealing conditions. The smaller the oxygen content, that is, the smaller the excess air coefficient, the greater the increase in chemical incomplete combustion heat loss and mechanical incomplete combustion heat loss; the larger the oxygen content, that is, the larger the excess air coefficient, the greater the amount of air supplied. Excessive 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 oxygen content of flue gas is of great significance to controlling the combustion process and achieving safe, efficient, and low-pollution emissions.
