Abstract
This work aims to analyze the performance of two different configuration porous burner made of silicon carbide operating with premixed combustion of LPG (liquefied petroleum gas). One of the configurations has a decrease of porous media downstream area. The other configuration remains the same, but both have two-layer porous media with different porosities and pore length. The main parameters discussed are the flame stability, the temperature profile in the porous medium and the radiation efficiency for the same equivalence ratio. This study indicated that the temperature profile and flame stability had the same behavior but the temperature on the surface had a difference for an operating range. The radiation efficiency decayed for the burner with smaller downstream area and bigger length, since thermal radiation is directly proportional to area.
