EXNFZRO®2 Explosion-proof Zirconia Oxygen Analyzer Significance of Measuring Oxygen Content with Zirconia Analyzer Flue gas oxygen content is one of the important monitoring parameters for boiler operation and an important basis for reflecting the completeness of combustion equipment and boiler operation. Its value is related to factors such as boiler structure, type and nature of fuel, boiler load, operating air supply conditions, and equipment sealing conditions. The smaller the oxygen content, i.e., the smaller the excess air coefficient, the more it indicates increased heat loss due to incomplete chemical combustion and mechanical incomplete combustion; the larger the oxygen content, i.e., the larger the excess air coefficient, the more it indicates excessive air supply. Excess air causes a drop in furnace temperature, which not only affects combustion but also carries away a large amount of heat and dust, increasing the calculated concentration of pollutant emissions. At the same time, a large air volume also increases the power consumption of flue gas exhaust. Controlling flue gas oxygen content is very important for controlling the combustion process and achieving safe, efficient, and low-pollution emissions. Application Scope The zirconia oxygen analyzer is an instrument used to monitor and control the oxygen concentration in combustion gases, boilers, and industrial furnaces. It is widely used in coal-fired power plants, gas boilers, waste incineration boilers, hazardous waste disposal incinerators, petrochemical cracking furnaces, metallurgical industry blast furnace hot blast stoves, oxygen-enriched combustion air pipelines, sintering furnaces, heating furnaces, heat treatment furnaces, metal material annealing furnaces, air separation oxygen production, food industry, cement kilns in the building materials industry, glass kilns, inert gas protection furnaces in the semiconductor industry, electrode material production furnaces in the lithium battery industry, and waste lithium battery recycling. It helps save energy and can also reduce CO2, SOX, and NOx emissions by controlling complete combustion, contributing to environmental protection, preventing global warming, and reducing air pollution.
