摘要：This paper discusses the performance investigations of a porous radiant burner (PRB) used in LPG cooking stove. Performance of the burner was studied at different equivalence ratios and power intensities. Thermal efficiency was found using the water-boiling test described in IS: 4246:2002. The newly designed PRB showed a maximum thermal efficiency of about 71%, which is 6% higher than that of the conventional burners. Influence of ambient temperature on the thermal efficiency of the PRB was also investigated. Using a PRB of 80 mm diameter at the operating conditions of 0.68 equivalence ratio and 1.24 kW power intensity, the thermal efficiency was found to increase from 61% at 18.5 oC to 71% at 31 oC ambient temperature. The CO and NOx emissions of the PRB are in the range of 9 to 16 ppm and 0 to 0.2 ppm, respectively, while the respective values for the conventional burner are in the range of 50 to 225 ppm and 2 to 7 ppm.
