Laminar Flame Velocity of Syngas Fuels

In this present study, burning velocities of $H2–CO$ mixtures (primary constituents of syngas fuels) are measured. Impact of different burner systems, $H2$ concentration, and different measurement techniques on the burning velocities of $H2–CO$ mixtures are discussed. The burning velocities of $H2–CO$ mixtures increase as the $H2$ contents in the mixture increase. Even with different burner systems using different methods, the burning velocities are aligned in the lean condition, but at rich conditions, they deviate from each other. The burning velocities of actual syngas compositions (based on different sources of coal) are also measured and analyzed. It was found that the effect of carbon dioxide had a more dominating role compared with nitrogen on the burning velocities.
