Effect of the ember element in increasing the efficiency of LPG stoves

The purpose of this study is to attempt to increase the efficiency of LPG stoves by using an ember element made of woven nickel wire arranged in layers. It is supposed that high-temperature embers are able to burn more fuel around the wire, thereby increasing the area of complete combustion. Testing was conducted by means of a boiling water test and the number of ember layers varied from one to four. It was found that the use of elements of fire without reflectors could increase efficiency by 8.32%, with the highest efficiency being with the use of a single layer ember element of the fire, of 61.71%. However, the use of elements of fire in the finned heat reflectors causes efficiency to decrease, as the pattern to put elements of fire interfere with the reflectivity. This means the heat reflection is blocked by the pattern and trapped between the reflector and pattern elements. As a result, the heat energy from the reflector reflection cannot be forwarded to the combustion zone. The test results also show that the temperature distribution from ember element use can increase the area of complete combustion.
