The Effect of Wire Mesh on Premix Combustion with Butane Fuel in Bunsen Burners

Combustion is an important process in a variety of industrial, laboratory and household applications, and the use of devices that control the characteristics of the fire is essential. Bunsen burner is one of the common laboratory equipment used to produce flames in experiments and heating processes. Wire mesh is placed above the Bunsen burner to control air flow and has a crucial role in premix combustion by affecting efficiency, stability and heat distribution. In this study, an experimental investigation will be carried out on Bunsen burners using wire mesh 30, 40, and 50. Furthermore, parameters such as flame stability, flame height, and combustion speed will be measured. The results of this study indicate that the looser the wire mesh density, the burning speed tends to decrease. When using wire mesh 30, the value of the combustion velocity reaches 3.09 cm/s. Meanwhile, when using wire mesh 50, the value of the combustion velocity increased to 3.24 cm/s. This indicates that the wire mesh is getting tighter, air and fuel flow can move faster, thus increasing the combustion velocity. In addition, the density of wire mesh also affects the high flame produced. By using wire mesh 30, the flame height reached 29.69 mm, while using wire mesh 50, the flame height reached 21.56 mm. This shows that the higher the wire mesh density, the flame tends to be more stable and has a smaller height.
