Laminar Flame Velocity of Syngas Fuels Available to Purchase

The paper presents the experimental measurements of the laminar burning velocity of H₂-CO mixtures. Hydrogen (H₂) and carbon monoxide (CO) are the two primary constituents of syngas fuels. Three burner systems (nozzle, tubular, and flat flame) are used to quantify the effects of burner exit velocity profiles on the determination of laminar flame propagation velocity. The effects to N₂ and CO₂ diluents have been investigated as well, and it is observed that the effects of N₂ and CO₂ on the mixture burning velocity are significantly different. Finally, the burning velocity data of various syngas compositions (brown, bituminous, lignite and coke) are presented.
