Tests were carried out with three different orifice plates with area ratios (orifice area to swirler exit area ratio) between 1.0 to 0.7 using 280mm inside diameter combustor of 1000mm length. Tests were conducted using commercial diesel as fuel. Fuel was injected at the back plate of the 45° vane angle swirler outlet using central fuel injector with single fuel nozzle pointing axially outwards. The aim of the insertion of orifice plates was to create the swirler pressure loss at the swirler outlet phase so that the swirler outlet shear layer turbulence was maximised to assist with fuel/air mixing. In the present work, orifice plate with smaller area ratios exhibited very low NOx emissions for the whole operating equivalence ratios. NOx reduction of more than 20% was achieved for orifice with 0.7 area ratio compared to area ratio of 1.0. Other emissions such as carbon monoxide increased with decrease in orifice area ratios. This implies that good combustion was achieved using smallest area ratios of orifice plate. 2008-09-15T02:09:19Z 2008-09-15T02:09:19Z 2006 Article Journal of Engineering Research and Education, vol. 3, 2006, pages 60-69. 1823-2981 http://hdl.handle.net/123456789/2199 http://www.unimap.edu.my/ en Kolej Universiti Kejuruteraan Utara Malaysia
