Abstract

This study was conducted to analyze the flame characteristics, which is generated through the combustion process according to air/propane mixture ratio and initial pressure as well as increasing the area of flame kernel generation by connecting high capacity capacitor to a standard ignition device. The experiment method involved constant volume combustion chamber system featuring a standard ignition device connected to amplified ignition device and the flame kernel and flame propagation were observed through the spark generated between the electrodes of spark plug. Also, ANSYS Fluent program was used to suggest interpretive results in order to analyze the characteristics of chemical reaction generated within the flame. Experiment conditions included initial pressure being configured at 2, 3, and 4 bar along with air/propane mixture ratio configured at excess air factor (λ) = 1.0, 1.2, and 1.4. Experimental results showed that amplified ignition increased the flame kernel generation compared to standard ignition and was able to decrease the rate of loss for flame propagation speed compared to that of standard ignition as initial pressure and excess air factor increased. In conclusion, the amplified flame can reduce flame instability by increasing the reaction zone rather than the standard flame even if the initial pressure increases. In addition, it is considered that the thermal expansion on the flame front can be increased by the amplification of ignition energy.
