摘要：
Experiments with combustion of diluted liquefied petroleum gases used as a fuel premixed with air are performed. From the experiment results, one can see that low-heat-value gases are capable of stable burning in a porous media burner. Distributions of species concentrations and flame temperature are measured. Based on these data, the flame is found to be most stable if the equivalence ratio is equal to 0.8. To improve the burner performance, experiments with different characteristics of porous media are performed. Optimal parameters of porous media are confirmed by subsequent numerical simulations. It is demonstrated that the properties of combustion in the porous media burner are superior as compared to those in the free flame burner.
