Abstract: A 3D simulation method was used to simulate the flow and combustion of micro-lobed burner and splitter burner, and the influence law of equivalence ratio between methane and oxygen on combustion characteristics was studied. The results showed that the streamwise vortices and augmentation in the mixing area between methane and oxygen could improve the mixing between fuel and oxidant, which can thus strengthen combustion to increase the combustion efficiency and temperature. Besides, although the combustion efficiency and temperature of micro-lobed burner are higher than that of the splitter burner, the combustion temperature and efficiency differences between these two burners at the same position go down as equivalence ratio decreases.

Key words: micro-lobed burner, splitter burner, equivalence ratio, temperature distribution, combustion efficiency
