Characterization of syngas laminar flames using the Bunsen burner configuration

Abstract : 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<4<1.2) and mixture compositions (1%<%H2<100%). As a result, a flame speed correlation established for lean syngas flames with 0.6<4<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.
