Investigation of natural gas flame temperature influenced spiral port on axial burner

This research focuses on the design of the inverse diffusion flame burner (IDF) that affected the natural gas flame temperature by studying numerical model. In order to enhance the flame temperature by the simulation study, the obtained simulation results were compared to the previous experimental study with less than a 10% difference. In this research, there are four types of the air and fuel ports, which consist of inner and outer spiral air ports, inner spiral fuel ports, and combinations ports, for the study of the flame temperature, flame characteristics and, flow characteristics of air and fuel. The obtained results showed that the outer spiral air port with the inner spiral fuel port designed affected the best mixing between air and fuel and the highest flame temperature (1,362.37 °C). Therefore, this study could enhance the natural gas flame temperature to higher than previous research burner by outer spiral air port and inner spiral fuel ports IDF axial burner.
