Natural gas burns cleaner than other fossil fuels producing half the carbon dioxide as coal and about a third less than oil. It also emits fewer amounts of toxic chemicals like nitrogen oxides and sulfur dioxide. The flue gas cleaning systems consisted of multicyclones for the removal of coarse particles. Dry wood fuel that consisted of
The sulfur in the natural gas may then be burned by the end user with the formation of sulfur dioxide (SO2), typically in low ppm or even ppb levels. Once the natural gas reaches saturation, any additional pressure drop and/or cooling will result in additional deposition. This can be a very big problem for cryogenic facilities such as LNG plants.
Combustion of standard fossil fuels (natural gas and ASTM Grade Oil) in commercial and industrial boilers results in the following nine emissions; carbon dioxide, nitrogen, oxygen, water, carbon monoxide, nitrogen oxide, sulfur oxides, volatile organic compounds, and particulate matter.
Coal pollution mitigation is a process whereby coal is chemically washed of minerals and impurities, sometimes gasified, burned and the resulting flue gases treated with steam, with the purpose of removing sulfur dioxide, and reburned so as to make the carbon dioxide in the flue gas economically  recoverable, and storable underground (the latter of which is called "carbon capture
