Enhancement of Combustion of Liquid Fuel on Porous Burner using Porous Emitter

Abstract

Abstract

Ability in the enhancement of combustion of diesel oil on porous burner (PB) installed porous emitter (PE) at the exit of burner was examined in this research paper. PE was constructed by lower than PB with distance of 18 cm. The pebbles carefully chosen in the same size like the solid sphere homogeneously and differently had two average diameters (d), i.e., 0.62 and 1.05 cm, were adopted as porous media. Three structures of porous burner were experimented. First structure was only PB whereas two structures else were PB with PE having different two size of d_PE. From study, it was found that the stable flame was located between two porous sections which was the region of three-way swirling air supplying. A better combustion was achieved by the burner installed PE because a higher temperature profile and a lower level of CO from this burner type. Moreover, it was observed that the enhancement of combustion in the case of PE for       d_PE = 1.05 cm. was better than the case of d_PE = 0.62 cm.
