To investigate the effects of the fuel properties on the blow-off characteristics of diffusion flames, systematic experiments using H_2,C_2H_2,C_2H_4,C_3H_8,C_4H_<10> and city gas as fuel and concentric cylinders as burner were carried out. As a result, it was evidenced that the effect of fuel properties bring to the term "S_<u0max>/δ_<min>" as the 1st report equation, though the exponents of (S_<u0max>/δ_<min>) in the equation should be modified to 0.57 instead of 0.5. S_<u0max> and δ_<min> mean to the maximum burning velocity and the minimum quenching distance of the related fuel-air mixture respectively. If the fuel is a mixture of extremely different diffusivities, the blow-off is hardly predicted by this equation because of superior diffusion of lighter component.
