[0002] The flue gas monitoring sampling structure is a device used to monitor and collect pollutants in the flue gas generated during the combustion process. The working principle of the flue gas monitoring sampling equipment is to introduce the flue gas into the sampling pipeline through the sampling probe, and use the sampling fan to extract the flue gas into the analytical instrument for analysis. The sampling pipeline usually includes components such as the inlet, filter and cooler, which are used to remove particulate matter in the flue gas and reduce the flue gas temperature to protect the normal operation of the analytical instrument. The flue gas monitoring sampling equipment can be used to monitor a variety of pollutants generated during the combustion process, such as sulfur dioxide, nitrogen oxides, particulate matter, heavy metals, etc. It has important application value in industrial production, environmental protection, safety monitoring and other fields. It can be used to detect and evaluate the emission level of combustion equipment, as well as to optimize and control the combustion process.
