摘要

In this paper, the development and performance tests of a novel porous radiant burner (PRB) used for LPG domestic cooking application are presented. The thermal efficiency of the burner was measured using the water boiling test described in BIS: 4246:2002. In order to optimize the porosity of the burner, burners having different porosities viz, 80%, 85% and 90% were tested at different equivalence ratios and wattages. The reported maximum efficiency is about 75% which is 10% higher than that of the maximum thermal efficiency of the conventional LPG domestic cooking stoves (metallic) available in the Indian market. The measured CO and NO_x emissions are in the range of 10-160 mg/m~3 and 0-0.9 mg/m~3, while the respective values of the conventional LPG domestic cooking stoves are in the range of 250-650 mg/m~3 and 4-7 mg/m~3. Within the range of equivalence ratios (0.5-0.7) and wattages (1.3 -1.7 kW) tested, the PRB showed a steady operation without any flash back with the thermal efficiencies well above 72%.
