This work presents result of visualisation of the characteristic combustion regimes of methane-air and syngas-air swirl-stabilized flames for an unconfined premixed burner (Re = 5000) and non-premixed combustion chamber (Re = 30000). Equivalence ratios were selected to have nearly equal values of the laminar flame propagation speed for the methane/air and syngas/air flames. Visualization for the premixed combustion for the model swirl burner revealed a similar shape of the flames for all mixtures. In contrast, during combustion of methane and syngas in the combustion chamber in the case of combustion in the combustion chamber, these differences in parameters cause completely visually diverse combustion modes.
