Abstract:   The low efficiency of LPG stove is affected by the loss of the heat to the surrounding. The previous researches have used the reflector to capture the potential heat loss from the system. It has been shown that this technique can improve the efficiency of LPG stoves. Since the reflection of the heat radiation is emitted to all directions, some of them may still loss to the environment. Therefore, we propose the use of finned reflector as the heat radiation guide to the combustion area and the load. Our finned reflector is made from a plate of stainless steel in the shape of cutted cone. The efficiency is evaluated by boiling water test technique. The performance of the LPG stove with the finned reflector is compared to that one without reflectors and non-finned reflector. Based on the results of the test, it is found that the use of one line finned reflector can improve the efficiency of LPG stove by around 5.21% better than that one without reflector. The efficiency of our finned reflector is higher than non-finned reflector by 1.75%. Based on the test of temperature distribution is obtained also that the use of finned reflector can increase the area of complete combustion.
