[0002] At present, China's sulfur dioxide and carbon dioxide emissions are ranked first and second in the world respectively. The main reason for the serious air pollution is the coal-based energy structure, and 70% of China's power generation industry is coal-fired. The flue gas emitted by coal-fired power plants contains smoke, carbon dioxide, sulfur dioxide, nitrogen oxides and a small amount of carbon monoxide. The smoke directly affects the environmental quality of the atmosphere. Carbon dioxide, sulfur dioxide, nitrogen oxides, etc. are all acidic gases and are the main factors in the formation of acid rain.

[0003] Therefore, the environmental monitoring of pollution sources should be done first. In the process of monitoring atmospheric pollution sources, collecting flue gas samples is an important task.
