natural gas boiler sulfur dioxide emission coefficient

How much carbon dioxide is produced when different fuels

The amount of CO 2 produced when a fuel is burned is a function of the carbon content of the fuel. The heat content or the amount of energy produced when a fuel is burned is mainly determined by the carbon (C) and hydrogen (H) content of the fuel. Heat is produced when C and H combine with oxygen (O) during combustion. Natural gas is primarily methane (CH 4), which has a higher energy content

relative to uncontrolled boilers. Sulfur Oxides - Emissions of SO2 from natural gas-fired boilers are low because natural gas typically contains less than 0.1 percent sulfur. Sulfur-containing mercaptan, however, is added to natural gas for detection purposes, leading to small amounts of SO2 emissions. Particulate Matter -

Are there CO2 emissions from natural gas? | HowStuffWorks

The burning of fossil fuels -- like coal, oil and natural gas -- releases gases into the air, mainly carbon dioxide, sulfur dioxide, methane and nitrous oxide. These also exist naturally in the Earths atmosphere to help hold in heat; however, scientists believe burning fossil fuels is causing an increase in these gases, which is leading to

40 CFR § 72.2 - Definitions. | CFR | US Law | LII / Legal

Natural gas contains 20.0 grains or less of total sulfur per 100 standard cubic feet. Additionally, natural gas must either be composed of at least 70 percent methane by volume or have a gross calorific value between 950 and 1100 Btu per standard cubic foot.

Boiler Emissions 101 - Boiler Service | Boiler Parts

Emissions of SO 2 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 SO 2 emissions. Boilers combusting unprocessed natural gas may have higher SO 2 emissions due to higher levels of sulfur in the natural gas.
