[0002] Flue gas is a mixture of gas and smoke, and is the main cause of atmospheric pollution in residential areas. The composition of flue gas is very complex. The gas includes water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons and nitrogen oxides, etc. The smoke includes fuel ash, coal particles, oil droplets and high-temperature cracking products.
