| Abstract | ||
| The combustion of the kerosene sprays inside a swirl type combustor is studied. To decrease the exhaust emissions such as NOx, NO and S02, Natural Gas (NG) or Liquefjed Petroleum Gas (LPG) fuels are added to the combustion air with different ratios. The effects of different percentages of NG (10, 20, 30 and 40%), different percentages of LPG (1, 2, 3 and 4%), and thermal load (70, 100 and 130 kW) on the flame characteristics were investigated. Also, a comparison between addition of NG and LPG was carried out. During the experimental study, the air to fuel mass ratio and air swirl number are kept constants at 30 and 0.5, respectively. The experimental results show that, as the NG percentage increases from 10 to 40%, the flame lengths and the flame temperatures were decreased, so that, NOx, NO, C02 and SOz concentrations were decreased, while CO and O2 concentrations were increased. Also, as the LPG percentage increases, the flame lengths and the flame temperatures were decreased, so that, NOx and NO, COz and SO2 concentrations were decreased, while COand O2 concentrations were decreased. | ||
