Effect of the ember element in increasing the efficiency of liquefied petroleum gas stoves

Abstract

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 can burn more fuel around the wire, thereby increasing the area of complete combustion. Testing was conducted by means of a Water Boiling Test (WBT) 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.

Mid‐infrared multiline absorption tomography for in situ analysis of thermochemical structure in natural gas‐fired cooker flame

“…However, conventional probing methods are not sensitive to detecting the small differences between the optimal design process and various operating conditions. Regarding the thermochemical parameters, temperature and CO 2 concentrations are two key parameters that are strongly related to combustion efficiency and carbon emission 4–6 .

[4][5][6] Thermocouples are frequently used for flame temperature measurements due to its operation convenience and relatively low cost. 7 Although the fine-gage thermocouple enables minimally intrusive measurements, quantitative corrections are required to account for the radiative and conduction heat loss.…”
