Laminar burning velocities of gas mixtures

Vishwanath Reddy Ardha, University of Texas at El Paso


In this study, burning velocities of hydrogen-carbon monoxide (H 2-CO) mixtures, which are primary constituents of syngas fuels, are measured. The effect of different burner systems, H2 concentration, and different measurement techniques on the burning velocities of H2 -CO mixtures is also discussed. The burning velocities of H2-CO mixtures increase with the increase in H2 content in the mixture. When compared with different burner systems using different methods, the burning velocity data almost coincide in the lean condition, but at rich condition the data stray away from each other. The burning velocities of actual syngas compositions (based on different sources of coal) are then measured and analyzed to determine the effects of diluents on the burning velocities of syngas mixtures. As diluents, carbon dioxide (CO2) plays a dominating role on the burning velocity when compared to nitrogen (N2). Finally, the burning velocities of H2-methane (CH4) mixtures are measured to determine the effect H2 on the burning velocities of H2-CH4 mixtures.
