Depending on the initial thermodynamic state of the mixture, the autoignition time can vary between hundreds of microseconds and several seconds. In premixed gas turbine combustion, long residence times in the premixer are beneficial in order to achieve a homogeneous mixture. However, this perspective is in contradiction with the requirement of avoiding autoignition. It is obvious that the residence time needs to be shorter than the autoignition delay time for a safe operation, but still long enough to achieve a good mixing.

Since hydrogen possesses a large mass diffusivity, leading to the comparably low Lewis numbers, it can diffuse much more rapidly to the flame zone, leading to a local hydrogen enrichment and shifting of the local 54 Flashback Mechanisms in Lean Premixed Gas Turbine Combustion mixture composition. For planar laminar flames the combined reaction and heat and mass transport processes, and therefore, any Lewis number effects are already incorporated in the laminar flame speed SL. The wrinkling of the flame front by turbulence activates, however, a further effect associated with the Lewis number.

They distort the flame front and can cause oscillations in the heat release rate. At high pulsation levels, significant periodic undershoots of the ­ urner flow velocity below its time-averaged value can result. If the b ­frequency is low enough an upstream propagation of the flame may ­occur, which can take place in the boundary layer, or in the core flow. In regular o ­ peration, high pulsation levels must be avoided for further reasons. Thus, flashback due to combustion instabilities should not ­occur during stable combustor operation, and this mechanism gains ­importance in the case of unexpected combustion instabilities.
