Karakteristik Pembakaran Premixed dari Campuran FAME (Fatty Acid Methyl Ester) dan Solar Murni

Abstract

This study aims to determine the effect of adding pure diesel fuel into FAME (Fatty Acid Methyl Ester) in the premixed combustion process, on changes in temperature and flame color. The experiment was carried out by burning a mixture of FAME oil and pure diesel oil, with the mixed  percentage of FAME and pure diesel fuel are 70%:30%, 80%:20%, 90%:10%, dan 95%:5%. From the analysis that has been done, it can be concluded that the smaller the equivalence ratio, the temperature will increase. This happens because the air added in the combustion process is perfectly mixed with the fuel, so that the heat generated is greater and the temperature also increases. In addition, it can also be seen that the temperature at point 1 is higher than point 2. This indicates that point 1 is the final combustion zone, where the fuel has burned out. The color of the flame will also become bluer when the equivalence ratio is getting smaller
