Description
Summary:Integrated Gasification Combined Cycle is a technology which has been studied widely as a future clean energy system. As one important portion of it, syngas premixed combustion is crucial due to its immediate impact on the efficiency and emission. However, its control is challenging since turbulent combustion in the chamber is extremely complex due to the composition variability and structural complexity of the combustion devices. Deep study on the laminar premixed combustion of syngas is of great importance for revealing the real complex turbulent combustion process. In the present paper, recent progress in fundamental research on laminar spherically premixed flame propagations of syngas, including laminar flame speed, Markstein length, flame stretch, cellular flame structure and self-acceleration are presented. Detailed summaries and discussions for different stages of the flame propagation are given. In particular, laminar flame speed and wrinkled flame front due to intrinsic flame instability are emphasized. Furthermore, future prospects on laminar spherically premixed flame propagation of syngas mixtures are discussed. •Various stages of laminar spherically premixed flame propagation of syngas mixtures are reviewed systematically.•Important parameters including laminar flame speed and critical Peclet number are emphasized and discussed.•Suggestions on further research directions are highlighted according to the analysis on the present work.
