[0002] Flue gas monitoring refers to the process of monitoring and analyzing pollutants in flue gas. It is usually used in the fields of industry, environment, and public health to ensure that flue gas emissions comply with relevant regulations and standards, protect human health and the environment. Flue gas monitoring usually uses gas analysis instruments and sensors to measure the concentration of pollutants in flue gas, such as sulfur dioxide, nitrogen oxides, particulate matter, etc. The monitoring results can be used to evaluate the compliance of emissions, formulate improvement measures, and provide a basis for environmental management and policy making.

[0007] The front end of the reinforcement rod is set to an arc structure and is adapted to the outer wall of the dust prevention cover.

[0008] Specifically, the dust prevention cover is a mesh structure, which can filter particulate matter or dust in the flue gas and does not affect the operation of the flue gas monitoring sensor.
