I have a question regarding the application of oxygen analyzers!
Thread Content
First, I would like to confirm: the main purpose of oxygen analyzers in industrial production is to detect oxygen levels, as it is necessary for explosion prevention! ? ? Is this how I understand it, right! ! ? Also, what is the purpose of low-pressure nitrogen and instrument air that are connected to the oxygen analyzer? ? Has anyone had experience using an online oxygen analyzer next to a vinyl chloride gas tank? What considerations should be taken into account when producing and designing the oxygen analyzer here? ? What type of oxygen analyzer is generally used here?
Most furnaces require an oxygen analyzer for their flue gas in order to control combustion efficiency.
The main functions of the oxygen analysis instrument on the heating furnace are: 1. Energy saving, 2. Environmental protection, 3. Prolonging the furnace’s service life. Low-pressure nitrogen and instrument air are used for the linear calibration of the analyzer. In other cases, analyzers are used for process control to protect the process media and equipment.
Oxygen analyzers are used in nitrogen fertilizer plants to measure the oxygen content in water gas or semi-water gas. Excess oxygen levels can pose a threat to safe production and even lead to explosions; therefore, it is necessary to strictly control the oxygen content in the mixed gas. Connecting to low-pressure nitrogen or instrument air is used to dilute the concentration of harmful gases and also serves to prevent explosions.
In industrial applications, the choice of oxygen analyzer depends on the location where it will be used. Zirconia analyzers are primarily used in the flue gases of heating furnaces; their purpose is to ensure a better ratio between gas and air, thereby enabling the furnace to operate more efficiently and using less gas, thus saving fuel； Oxygen analyzers are used in tank areas to more accurately measure the oxygen content in the nitrogen purge gas. A high oxygen level reduces the effectiveness of the nitrogen purge; the presence of large amounts of air increases the risk of fire. Measuring oxygen allows for the determination of the purity of the oxygen coming out of the distillation tower, while measuring trace amounts of oxygen enables the assessment of the purity of the nitrogen coming from the same tower. The application areas for these devices vary

Measuring oxygen levels allows one to determine the purity of the oxygen coming out of the distillation tower, while measuring trace amounts of oxygen can help determine the purity of the nitrogen coming from that tower. Depending on the location where they are used, oxygen analyzers serve different functions, and they require different measurement principles as well as different explosion-proof ratings to meet the requirements of the surrounding environment.
