.... To overcome combustion issues and instabilities of gas fired gas turbines due to the variability of gas incoming gas quality, a new sensor called NIRIS NG has been designed which analyzes the natural gas composition at the inlet of the turbine burners. The design of the NIRIS NG sensor boasts a short response...

... of natural gas, methane, and hydrogen were also taken into account -as major components of biogenic gas mixtures. It was found that the reaction behavior of the wood gasification product (N 2 , CO, H 2 , CO 2 , CH 4 ) is mainly determined by its H 2 content, besides CH 4 ; methane determines the kinetic...

... successfully recorded for ethylene at approximately 16 bar, 850K and at equivalence ratios between 2.6 and 3.3. Methane, natural gas and ethylene (0.5 < φ < 2.5) failed to auto-ignite within the test section. Model predictions were found to agree with the ethylene measurements, although improved...
