| Abstract | ||
| Combustion processes are the primary sources of air pollution. Measures are taken to reduce emissions from combustion processes. This paper is an experimental study of the effect of spray angles on the emission of pollutants from a continuous combustion chamber using the liquid fuels (gas oil). The angles of spraying studied are 30°, 45°, and 60°. The pollutants CO, SOOT, and NOx are measured. The results showed that the emissions at 45° were less than that at 30° at the corner of 30°. This reduction in emitted pollutants was due to the decrease in droplet diameter associated with the increase of the spray's angle. Better atomization and mixing in this case improved and the mixture is more homogeneous. However, this caused higher temperatures leading to increased rates of emission of SOOT and NOx. The greater the angle of the spray displays, droplets diameters decreased, and the amount of evaporation increased producing higher combustion temperature and decreased emission of CO. However, this caused an increase in SOOT and NOx emissions. | ||
