The abbreviation N  is commonly used as a reference to all oxides of nitrogen and the examples of oxides of nitrogen are NO, N  and O. These emission gases mostly come from the combustions of fossil fuels and biofuels in industrial activities and also in road traffics globally. N  as a pollutant deserves special attention because of its various issues on human’s health and environment. Some of these issues are global warming, acid rain, ozone layer depletion and photochemical smog. To address these issues, some studies are concentrating on the reduction of NO emission from the combustion process. This paper describes a study in the effects of swirling flow generated by using a radial swirler on flame characteristics that is related to the emission of NO. The radial swirlers used in this study have the angles of 40°, 50° and 60°. Diesel is used as a fuel in this study. The results show that all radial swirlers used have different effects on the flame characteristics. From all these radial swirlers, the one with an angle of 60° produces flame with high temperature, short flame length with blue colour and wide spread. The results also show a short time residence during combustion process that could reduce the formation of CO and N .Â
