Jaafar mshaiful@unimap.edu.my Radial swirler Orifice plate NOX reduction CO emissions Link to publisher's homepage at http://www.utm.my/ This paper presents the effect of inserting swirler outlet orifice plate of different sizes at the exit plane of the flat blade radial air swirler in liquid fuel burner system. 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 280 mm inside diameter combustor of 1000 mm length. Tests were conducted using commercial diesel as fuel. Fuel was injected at the back plate of the 60o 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 15 percent was achieved for orifice with 0.7 area ratio compared to area ratio of 1.0. Other emissions such as carbon monoxide increased with decreasing in orifice area ratios. This implies that good combustion was achieved using smallest area ratios of orifice plate. 2011-08-05T02:59:50Z 2011-08-05T02:59:50Z 2008-12 Article Jurnal Mekanikal, (26), 2008, pages 96-106 0127-3396 http://eprints.utm.my/8531/1/MSAIshak2008-The_Influence_Of_Orifice_Insertion.pdf http://hdl.handle.net/123456789/13386 en Universiti Teknologi Malaysia (UTM) |
