gas boiler sulfur dioxide emissions

Smoke emission and control of fuel gas boiler - Ningbo

Emissions of SO2 from natural gas-fired boilers are low because pipeline quality natural gas typically has sulfur levels of 2,000 grains per million cubic feet. However, sulfur-containing odorants are added to natural gas for detecting leaks, leading to small amounts of SO2 emissions. Boilers combusting unprocessed natural gas may have higher SO2 emissions due to higher levels of sulfur in the natural gas.

Boiler Combustion | CleanBoiler.org

After leaving the boiler and passing through a rotational air-heater, the combustion gas enters a reactor, which is a special-purpose variation of the boiler flues vertical segment. Further reduction of sulfur dioxide contents occurs in the reactor due to the introduction of an alkaline water solution and the combustion gas being cooled down.

Sulfur Dioxide Scrubber: pH Control | Yokogawa America

The sulfur dioxide emission value can reach 200 mg/Nm3 or less. Sulfur dioxide emissions from natural gas-fired boilers can generally meet national requirements. The emission control of nitrogen oxides is controlled by combustion, and the flame combustion temperature, excess air coefficient, or the increase of the flue gas recirculation system are used to achieve the emission standards through the burner.

For example, requirements on limit the amount of sulfur in diesel (or #2 oil) for both transportation use as well as for stationary use in boilers. Common non-standard fuels such as Wood, off-gasses from digesters and waste oil have their own specific regulations and the variation in the fuel supply requires specific site analyses.
