The inverse diffusion flame is formed in the combustor of a partial-combustion-type gas reformer for tar reduction in the producer gas formed by the gasification of the woody biomass. Pyrolysis and polymerization of tar occur simultaneously at the vicinity of the inverse diffusion flame. Soot forms during the polymerization of tar. In this study, to reveal the effect of changing the diluent of oxidizer on the formation of soot and polycyclic aromatic hydrocarbons (PAHs), laser induced incandescence (LII) and laser induced fluorescence (LIF) were at domain of laminar inverse diffusion flame. Results show that carbon dioxide addition to the oxidizer makes the flame sharp and soot and PAHs decreased.
