With the gradual improvement of people’s awareness of environmental protection and energy saving, many large and medium-sized enterprises such as iron and steel metallurgy, petrochemicals, and thermal power plants have improved the efficiency of combustion, reduced energy consumption, reduced pollutant emissions, and protected the environment. An important way to enhance product competitiveness. The steel rolling furnaces in the iron and steel industry, boilers and other thermal equipment in the power industry are the major energy consumers in various industries. Therefore, how to measure and improve the combustion efficiency of the combustion device and determine the best combustion point is of great concern.
Zirconia oxygen analyzer, also known as zirconia oxygen analyzer, zirconia analyzer, zirconia oxygen meter, zirconia oxygen meter, is mainly used to measure the oxygen concentration of the flue gas in the combustion process, also applies to non- Combustion gas oxygen concentration measurement. An electrochemical cell with a constant temperature inside the sensor generates a millivolt potential, which directly reflects the oxygen concentration in the flue gas. Applying this analyzer to combustion monitoring and control will contribute to full combustion, reduce emissions of CO2, SOx, and NOx and contribute to preventing global warming and air pollution.
Precautions for Use Oxygen analyzers can be divided into three categories based on the principle: oxygen analyzers for fuel cells, zirconium oxide sensors for zirconium oxide, and magnetic oxygen analyzers. Oxygen analyzers have many precautions in use, otherwise they are prone to problems such as inaccurate analysis results. Therefore, Guangzhou Techtronic Electronic Equipment Co., Ltd. has several considerations for your reference:
1. Before the initial use of the oxygen analyzer, leaks should be made to the connection points, solder joints, valves, etc. to ensure that the oxygen in the air will not leak back into the pipeline and the instrument, resulting in high measurement values.
2. Before using the instrument again, purify the pipe system to blow off the leaked air, and ensure that there is no leakage of air when connecting the sampling line.
3. The change of oxygen content in the sample gas will be affected by the material and surface roughness of the pipe. Therefore, the copper pipe or polished stainless steel pipe is generally used for the connection pipe, instead of plastic pipe and rubber pipe.
4. When microanalysis is performed, it is necessary to avoid contamination of the sample gas by various pipe fittings, valves, headers, and other dead angles. Therefore, it is necessary to simplify the gas system as much as possible, and the dead angle of the connector must be small. Power to prevent dissolved oxygen from escaping and causing pollution, it is best to use water seals, oil seals, and wax seals to ensure accurate data.
The ZR202S
Zirconia Oxygen Analyzer is an integrated analyzer that combines probes and transducers. Both zirconia oxygen analyzers do not require sampling equipment and can be installed directly on the flue wall or in the furnace to measure the oxygen concentration in the flue gas. The converter shows zirconium pool temperature and zirconium pool electromotive force, as well as oxygen concentration. The analyzer is best suited to monitor combustion and control low oxygen combustion in various industrial furnaces in explosive atmospheres.
