what are the causes of natural gas boiler sulfur dioxide

Flue gases and combustion product hazards from heating

Sulfur Oxides. Natural gas contains very little sulfur and as a result, produces very low SO2 emissions. The most common additive to add odor to natural gas is Mercaptan (CH3SH : Methanethiol). WHAT TO EXPECT WHEN NATURAL GAS IS FIRED IN A COAL-FIRED BOILER ⇧ Furnace exit gas temperature (FEGT) is likely to increase

Natural Gas Fired Boilers

1.4.3 Emissions3-4 The emissions from natural gas-fired boilers and furnaces include nitrogen oxides (NOx), carbon monoxide (CO), and carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), volatile organic compounds (VOCs), trace amounts of sulfur dioxide

What kind of pollution does a biomass burner emit? - PFPI

Jul 28, 2020 · This is caused by the formation and condensation of sulfur acid. The acid is formed in the combustion process from the sulfur introduced into the system with the fuel. The hot exhaust gases pass through several steam drums in the HRSG and release heat to produce superheated steam.

» Processing Natural Gas NaturalGas.org

Part of the reason natural gas is now so prevalent is that it burns cooler than fuel oils and has no nitrogen in it, making it inherently a lower producer of NOx. Refineries have been mandated to reduce levels of sulfur, nitrogen and other pollutants in order to reduce emissions. Post-combustion control

Sulfur Smell in the House? 6 Things to Do ASAP - Bob Vila

Sulfur dioxide. SO2 is a colorless gas with a pungent odor and is primarily associated with oil- and coal- burning appliances. At low levels of exposure, SO2 can cause eye, nose, and respiratory tract irritation. At high exposures, it can cause the airways to narrow, leading to chest tightness and breathing problems.

Heating System Emissions - Natural Gas Efficiency

The combustion of fuels containing sulfur (primarily oils and coals) results in pollutants occurring in the forms of SO2 (sulfur dioxide) and SO3 (sulfur trioxide), together referred to as SOx (sulfur oxides). The level of SOx emitted depends directly on the sulfur content of the fuel.

The Danger of Sulfur in a Gas Turbine - Identifying Threats

Natural gas from some wells contains significant amounts of sulfur and carbon dioxide. This natural gas, because of the rotten smell provided by its sulfur content, is commonly called sour gas. Sour gas is undesirable because the sulfur compounds it contains can be extremely harmful, even lethal, to breathe.
