Pollutant emission is becoming a serious environmental issue nowadays. Stringent legislations were introduced in several countries to limit the permissible levels of pollutant particle emission in major combustion systems such as burners and furnaces that have been widely used in industrial application. In this study, a numerical study of laminar coflow diffusion flame was performed in a model combustor using the commercial software, ANSYS Fluent 19.1. The main focus of this study is to understand the effect of the variation of flow characteristics in the coflow diffusion flame on the prediction of NOx and soot emissions. Comparison study of the pollutant formation was performed with different hydrocarbon gaseous fuels (methane, ethylene, ethane, propane and n-butane) with detailed high-temperature reaction mechanisms. In addition, Moss-Brookes model was adopted to obtain the soot emission data. Variation of the flow characteristics on the pollutant formation was performed by examining the change in fuel ...
