An atmospheric fixed pollution source refers to a fixed emission source of atmospheric pollutants, including boilers, kilns, and exhaust pipes for residents' living in factories, enterprises, and food and beverage service units. Among them, boilers are one of the main emission devices of atmospheric fixed pollution sources. With the development of human production, the prosperity of life, especially the development of modern industry, agriculture, and energy, the harm caused by pollutants emitted by atmospheric fixed pollution sources to the environment has become increasingly obvious.

[0003] Currently, the main methods for detecting fixed pollution sources are the gravimetric method, and there are also light scattering, oscillating balance, and β-ray methods.
