Description Paper from the AFRC 2015 conference titled Air staged double swirl low NOx LPG burner
Abstract Due to the environmental concern and the realization of the harmful effects of pollutants emerging from combustion systems burning fossil fuels, new strategies have been developed in the design of combustion equipment. These strategies must take into account reduction of the levels of NOx, CO and UHC while maintaining high combustion efficiency, wider stability limits and safety. The present work aims at providing a comprehensive experimental study of the flame characteristics of a staged double swirl low NOx gaseous burner. This burner configuration is a replacement of the traditional coaxial burner having a central fuel jet with a single coaxial swirler. The proposed configuration allows for better control of the degree of mixing and charge stratification by varying the swirl angles, inlet momentum ratio and equivalence ratio of the annular and outer streams. The scope of this experimental program is divided into three distinct stages, namely; the flame stability (stage 1), exhaust emissions (stage 2) and in-flame measurements (stage 3).
