RE: GAS-L: Flame speed in producer gas.
At the Technical University of Denmark we have determined the laminar flame speed of producer gas and mixtures of producer gas and natural gas. This was done applying a spherical combustion bomb containing a mixture of fuel and air. Electrodes located at the center of the bomb ignited this mixture and the laminar flame speed was calculated from a measured pressure-time history. For a producer gas with the composition CH4=2%, CO=15%, H2=35%, N2=30% and CO2=18, the laminar flame found to be 2.0 m/s @ lambda=1.0 and 1.1 m/s @ lambda=1.25. Further details about the determination of the flame speed and the flame speed of mixtures of producer gas and natural gas can be found in the SAE paper 1999-01-1571. In the SAE paper 2000-01-2824 we have reported different fuel properties of mixtures producer gas and natural gas (as e.g. flame speed) deduced from combustion engine experiments.

Subject: GAS-L: Flame speed in producer gas.
I'm looking for the flame speed of producer gas. Does someone know
the values or where I can find them. I can find the flame speed of H2 and
CO, but I don't know how calculate the flame speed for the mixture.
