Özet

LPG (Liquefied Petroleum Gas) is a colorless, odorless, combustible gas that is heavier than air, obtained by distillation of crude oil in refineries or by separating from natural gas, liquefied under a certain pressure. LPG consists of hydrocarbons such as propane (C3H8), butane (C4H10), and their isomers or mixtures. LPG is more preferable due to its low carbon emission and its higher heat value and efficiency, and it is also more environmentally friendly than other fuels. It is widely used in residences, industry, and vehicles as fuel and because of these advantages, the consumption of LPG increases over the world.

In this study, the combustion characteristics of cold flow and flame in a household cooker have been experimentally investigated. The flame temperature, gas flow velocity, and combustion emissions of LPG in the household cookers for two flow rates (maximum and minimum) under laboratory conditions were measured. The pressure of LPG used in the study is 2-3 bar and consists of a mixture of 70% butane and 30% propane. The domestic cooker has three different sizes of cookers, and each cooker is called according to the diameters of the flame outlet as Cooker 1, Cooker 2, and Cooker 3, respectively. The outer diameter of the Cooker 1 is 8 cm, the outer diameter of the Cooker 2 is 7 cm, and the that of the Cooker 3 is 5 cm. Within the scope of the investigation, the fixed flame exit point was determined in each cooker, and the temperatures, velocities, and emissions of gas flows were measured based on the reference point. The measurement range is from the point where the exit point (0 cm) to 3 cm (including 3 cm) range with 0.5 cm intervals. The horizontal, vertical, and diagonal measurements starting from the exit point of the flame were performed at maximum flow and minimum flow rate. The results are presented in the following graphical figures.

In our household cooker, Cooker 1 is 0.6 lt/min at maximum flow rate and is 0.2 lt/min at minimum flow. When Cooker 2 is 0.25 lt/min at the maximum flow rate, and at minimum flow 0.1 lt/min; Cooker 3 is 0.2 lt/min at the maximum flow rate and 0.1 lt/min at minimum flow.
