Fuji High Dust oxygen analyzer is mainly used in: ethylene and aromatics production in the petrochemical industry, hydrogenation process, inert gas reaction furnace and container, gaseous or nitrogen purification, boiler or incineration furnace, etc. Bottle filling and filling, ships with inert gas generator, carbon dioxide purity testing in the beer industry, and heat treatment industrial furnace.
1, Fuji high dust oxygen analyzer can control the best combustion point and improve the combustion efficiency
Fuji high dust oxygen analyzer is a new type of oxygenometer. Its structure is relatively simple, but it is convenient to use and widely measured. Therefore, it is widely used in the industrial field.
In industrial production, fuel burning heating equipment such as heating furnaces and boilers has not been used. Taking the heating furnace or boiler as an example, the effective heat is to heat the material to heat or melt (and the process of process). The physical heat taken away by the furnace flue gas is the main part of the heat loss. When the amount of wind drum is too large (that is, the large -fire ratio alpha is too large), although the fuel can be fully burned, the excess overcurrent air in the flue gas is too large, which is manifested as the high O2 content in the flue gas. Increasing, the heat efficiency is low. At the same time, excessive oxygen will generate harmful substances such as SO2 and NOX in N2 in the fuel. For rolling steel heating furnaces, excessive oxygen content in flue gas will also cause thickening iron oxygen oxide skin and increase oxidation and damage.
The so -called improvement of combustion efficiency is to burn the best amount of fuel to an appropriate amount of air composition. Thermal efficiency is related to the content of CO, O2, CO2 in flue gas, and factors such as the content of CO, O2, CO2, and smoke exhaust temperature, heating load, and atomization conditions. Therefore, the content of the air consumption coefficient λ can be adjusted by measuring and controlling the content of CO, O2, and CO2 in the flue gas to achieve the highest combustion efficiency.
2, What is the principle of Fuji high dust oxygen analyzer?
Fuji high dust oxygen analyzer is mainly composed of converters and detectors. The converter is mainly used to absorb the flue gas in the flue. It is transported by the pipeline to send the flue gas to the detector component. The probe analyzes the oxygen content in the smoke, and directly detects the combustion.
Fuji high dust oxygen analyzer has the advantages of more simple, high sensitivity and resolution, high measurement range, and faster response speed.
The field of smoke analysis instruments is widely used, such as:
The circulating fluidized bed boiler of the thermal power plant is used in the flue gas monitoring of the burning control room; the steel plant rolling heating furnace is used to solve the atmosphere of the furnace atmosphere when reducing oxidation and burning or decarburized layer thickness; Whether to burn through the air; develop a new type of burner (heat storage, low -NOX, and radiation tube) for design and research for burner structure dimensions; car tail gas emissions detection; food industry water measurement; other industrial kiln and garbage garbage Incinement furnace flue gas monitoring.
3, What are the characteristics of Fuji high dust oxygen analyzer?
As a easy -to -use oxygen analyzer, the characteristics of the oxygen analyzer are also obvious. For example, if the service life is long, it is not a problem for three or five years. In addition, its antioxidant capacity is very strong, and it can work in the temperature of the smoke temperature of 0 to 1200 degrees Celsius and move. Furthermore, Fuji high dust analyzer can display the detection results in the liquid crystal menu -style panel. The data is intuitive, which is convenient for user analysis to determine whether the fuel in the device is fully burned. It is also based on these remarkable features that many equipment that requires oxygen measurement and related factories will now use this instrument.
