Orthogonal design of a small gas burner

Abstract

This paper focus on orthogonal design of a small gas burner which burns clean gas fuels such as natural gas (methane), hydrogen. In order to optimize the structure of the gas burner, several burners with different sizes are presented and discussed in this paper, by comparing the Computational Fluid Dynamics (CFD) simulation results of the combustion characteristic basing on the orthogonal design method. The burner structure is optimized basing on the CFD simulation. The CFD simulation results show that the optimized burner gets the better performance and higher temperature at the outlet than other structures.
