Characterization of syngas laminar flames using the Bunsen burner configuration
Laminar flame speeds of syngas mixtures (H2/CO/Air) have been studied using the Bunsen flame configuration with both straight and nozzle burners. The flame surface area and flame cone angle methodologies, respectively based on the OH (*) chemiluminescence and Schlieren imaging techniques, have been performed to extract flame speeds for a wide range of equivalence ratios (0.3 < φ < 1.2) and mixture compositions (1% < %H 2 < 100%). As a result, a flame speed correlation established for lean syngas flames with 0.6 < φ < 1.0 and 10% < %H2 < 70% is proposed. A particular attention has been devoted to the development and validation of the OH (*) chemiluminescence methodology with the identification of important parameters governing the measurement accuracy. © 2010 Professor T.
