Air swirler adds sufficient swirling to the inlet flow to generate central recirculation region (CRZ) which is necessary for flame stability and fuel air mixing enhancement. Therefore, designing an appropriate air swirler is a challenge to produce stable, efficient and low emission combustion with low pressure losses. A liquid fuel burner system with different radial air swirler with 280 mm inside diameter combustor of 1000 mm length has been investigated. Analysis were carried out using four different radial air swirlers having 30°, 40°, 50° and 60° vane angles. The flow behavior was investigated numerically using CFD solver Ansys Fluent. This study has provided characteristic insight into the formation and production of CO and pollutant NO inside the combustion chamber. Results show that the swirling action is augmented with the increase in the swirl angle, which leads to increase in the center core reverse flow, therefore reducing the CO and pollutant NO formation. The outcome of this work will help in finding out the optimum swirling angle which will lead to less emission. 2015-06-08T04:40:51Z 2015-06-08T04:40:51Z 2014 Article Jurnal Teknologi (Sciences and Engineering), vol. 69(2), 2014, pages 71-77 0127-9696 (P) 2180-3722 (O) http://www.jurnalteknologi.utm.my/index.php/jurnalteknologi/article/view/3110 http://dspace.unimap.edu.my:80/xmlui/handle/123456789/40141 en Penerbit UTM Press |
