In the present work, the effect of porosity and loading height on the performance of the domestic gas burners, using LPG as fuel, is studied extensively through experimentation. Water Boiling Test (Version 4.2.3) as per the recommendations of International Organization for Standardisation International Workshop Agreement (ISO-IWA) is adopted to determine the thermal efficiency of the domestic gas stove. It is observed that, by increasing the number of holes in intermediate and innermost rows by about 96% and 73%, the pitch gets reduced by 58% and 65% respectively. Due to increased porosity, the thermal efficiency in hot and cold phase is increased by about 30% and in simmer phase the thermal efficiency is increased by about 26%. In addition to this, it is also observed that there exists an optimum height for keeping the container over the gas burner (loading height) up to which the thermal efficiency increases and beyond that, the thermal efficiency drops significantly. The optimum loading height for cold and hot phase is 14.1, and 14.6 mm respectively for the LPG cookstove used in present work (1–3 kW). The thermal efficiency at cold and hot phase, while running the gas stove with stand (11.25 mm) is reduced by about 18.5 and 16.5% respectively compared to the optimum loading height of 14.1 and 14.6 mm respectively.

在目前的工作中，通过实验广泛研究了孔隙率和装载高度对以液化石油气为燃料的家用燃气燃烧器性能的影响。根据国际标准化组织的建议，采用水沸腾测试（4.2.3版）来确定家用燃气灶的热效率。观察到，通过将中间行和最里面的行中的孔数增加大约96％和73％，间距分别减小了58％和65％。由于孔隙率的增加，热相和冷相的热效率提高了约30％，而immer火相的热效率提高了约26％。除此之外，还观察到，存在用于使容器保持在燃气燃烧器上方的最佳高度（装载高度），热效率增加到该高度，超过该高度，热效率显着下降。对于当前工作中使用的LPG炉灶，最佳的冷态和热态加载高度分别为14.1和14.6 mm（1-3 kW）。与最佳装载高度分别为14.1和14.6 mm相比，在运行带有支架（11.25 mm）的燃气灶时，冷热阶段的热效率分别降低了约18.5和16.5％。
