英文摘要As a kind of fuel with low-carbon emissions, hydrogen-rich syngas has a large resource potential and is a promising alternative energy resource. A series of experiments in a constant volume combustion bomb are carried out to investigate the effects of turbulence and diffusional-thermal (DT) instability on a hydrogen-rich syngas turbulent premixed flame. The flow field in the constant volume combustion bomb is calibrated, and the turbulent flow field's homogeneity and isotropy were investigated. The effects of different speeds of fan (1366-4273 rpm), hydrogen fractions (55%-95%), pressures (1.0-3.0 bar), and equivalence ratios (0.6-1.0) on the hydrogen-rich syngas turbulent premixed flame are studied. According to the analyses, the flow field in the experimental device exhibits good homogeneous and isotropic characteristics. With the increase of turbulence intensity, equivalence ratio, hydrogen fraction, or pressure, the turbulent flame propagation speed increases gradually. As the hydrogen fraction increases or the equivalence ratio decreases, the effective Lewis number decreases, and the effect of DT instability on the flame increases. The research in this article is crucial for the clean and efficient utilization of hydrogen-rich syngas and the design of related burners. In this work, a stable and uniform isotropic turbulent flow field is established. The flame evolution and propagation speed of hydrogen-rich syngas are evaluated. The influence of turbulence intensity, equivalence ratios, pressures, and hydrogen fractions on flame propagation characteristics are studied and the influence of diffusional-thermal instability on flame propagation speed is analyzed.image (c) 2023 WILEY-VCH GmbH
