... Abstract Carbon dioxide emissions in gas turbine power generation can be reduced by adding an increasing amount of hydrogen to the existing natural gas-fueled combustion systems. To enable safe operation, more insight on how H 2 addition affects turbulent flame speed and other important flame...

... compositions, but do not capture the pressure sensitivity of S T,GC . We suggest that these pressure effects are more fundamentally a manifestation of non-quasi-steady behavior in the mass burning rate at the flame leading points. syngas hydrogen pressure turbulent flame speed global consumption...

... The turbulent flame speed (S T ) is proposed to be an indicator of flashback propensity for hydrogen-rich fuel gases at gas turbine relevant conditions. Flashback is an inevitable issue to be concerned about when introducing fuel gases containing high hydrogen content to gas turbine engines...

... There is an obvious lack of data and understanding of the behavior of turbulent flames at high temperature and high pressure, especially concerning hydrogen containing fuels. Among the many relevant parameters, the turbulent flame speed “ S T ” is one of the most interesting for scientists...

... H 2 /CO mixture properties upon turbulent flame speeds — a number of prior studies have noted that different fuels, with the same laminar flame speed and combusted in the same turbulent flow, can have widely different turbulent flame speeds. This effect is believed to be due to flame speed...

... The present experimental study focuses on flame characteristics and turbulent flame speeds of lean premixed flames typical for stationary gas turbines. Measurements were performed in a generic combustor at a preheating temperature of 673 K, pressures up to 14.4 bars (absolute), a bulk velocity...
