| Summary: | Combustion of liquid fuel sprays produces NOx, CO and other emissions that have an adverse impact on the environment and humans. This study is conducted to produce low-emission combustion with the use of double radial swirler. Swirling flow burning will enhance the mixing of fuel and air to produce a flame that is more stable and efficient. In this study, weak swirler with an angle of 30º is set as a primary swirler and strong swirlers each with an angle of 40º, 50º and 60º are set as the secondary swirler. Combinations of these swirlers helped the mixing of fuel and air during combustion. The results show, the combination of swirlers 30º/60º produced the highest temperature profile, the best flames, more stable and shorter than other combinations. NOx emissions for the combination of swirlers 30º/60º at stoichiometric are 15.6% lower than the combinations of swirlers 30º/40º. Other emissions such as CO, also shows 8.4% of reduction in the combination of swirlers 30º/60º. These results indicated that double swirlers helped in reducing emissions during combustion and also producing an environmentally friendly combustion system. |
