30 thg 6, 2016 - Impact of fuel composition on gas turbine performance. . Fuel gas with a large amount of inert components (such as CO2 or N2) has a low Wobbe index, while substances with a large amount of heavier hydrocarbons have a high Wobbe index. Pipeline quality natural gas has a Wobbe index of about 1220. General Electric heavy-duty gas turbines have the ability to burn a wide classification of gaseous fuels as . Gas Composition to C6+ (gas chromatography). Other compounds present can be carbon dioxide (CO2) with up to a few percent and nitrogen (N2), commonly a few percent but up to 10%. The composition of the natural gas will influence the heating value as well as the combustion characteristics. turbines within E.ON's UK gas turbine fleet has shown clear trends in pollutant emissions and combustion dynamics with changing fuel composition. These. Gas turbine thermal performance is dependent on many external conditions, including fuel gas composition. Variations in composition cause changes in output . Gas turbine thermal performance is dependent on many external conditions, including fuel gas composition. Measured performance must be corrected to . The quality and composition of fuel burned in a gas turbine impacts the life of the turbine, particularly its combustion system and turbine section. The fuel . U.S. natural gas composition is expected to be more variable in the future. Liquefied . variability on pollutant emissions for premixed gas turbine conditions. composition.
