| Summary: | Combustion industries for many decades dealing with the issues in reducing the emissions without affecting the performance of combustion. The present study aims
to investigate the performance of swirler mechanism which combining between both axial and radial types to reduce emissions and increase the mixing process via the nonpremixed method. Each of axial and radial swirler consisted with 8 blades vane. Swirl angle for radial swirler is 35° and inclination angle for axial swirler is 15°. The swirler is
designed using Solidworks software package and CFD analysis was then performed using ANSYS Fluent software package. The fuel used is liquefied petroleum gas (LPG)
gas which contained 30% propane and 70% butane. The turbulence model standard kepsilon was used in this study. The result found that the combined swirler was capable
to reduce CO emission as the complete reaction into CO2 component was higher. This is due to the broader region of temperature and higher velocity magnitude produced
by the combined swirler. However, the maximum temperature result for axial swirler was higher than the combined swirler. As a recommendation, the inclination blade angle in the axial swirler of the combined swirler should be increased to increase the temperature value. |
