Experimental Study And Numerical Simulation Of A Novel Oxygen-fuel Burner

A burner assembly is provided for combining oxygen and fuel to produce a flame.The burner features has a direct impact on the furnace aerodynamic field and the combustion state.To design burners generally have to consider many aspects of notes, including:a good flow field, ignition easily,stable flame and so on.Therefore, the burner design and experiment is important to maintain a good operation of the combustion equipment.Generally before the new burner ignition test we have to perform a cold burner experiment and numerical simulation to study the flow characteristics.In this paper, a1.5MW petroleum coke Oxygen-fuel burner was studied.We use the temperature labeling method to study the flow characteristics in the cold test, and the numerical simulation is calculated through the commercial simulation software FLUENT.Should be noted that, here the temperature labeling method is performed by Spraying liquid carbon dioxide into a certain wind pipe.then the liquid carbon dioxide evaporation endothermic and cool of this wind.Temperature measurement by infrared camera.The infrared camera can capture the transient temperature field.Finally, MATLAB and other software are used to handle the temperature field pictures and test data.By comparison, the Cold tests and numerical simulations show similar results.This shows that this temperature labeling method is feasible and the calculation model used in the numerical simulation is appropriate.
