炉内燃烧器射流组组合特性分析

Analysis of the Jet Flow Group Combination Characteristics of a In-furnace Burner

以某燃油火烧炉为具体研究对象,调整燃烧器的几种主要组合方式,对炉内三维湍流燃烧场特性进行数值模拟,得到了燃烧器射流组组合特性对炉内空气动力场的影响规律,并将模拟计算的结果与实验结果比较.计算数据与实测结果吻合较好,这对于确定燃烧器组合工况、设计试验方案具有实际意义,为室内火烧炉运行工况的调节提供了理论参考依据。

With an oil-fired boiler serving as a concrete object of study,the in-furnace three-dimensional turbulent flow combustion field characteristics were numerically simulated by adjusting several main combination modes of the burners and the regularity of the jet flow group combination characteristics of the burners influencing the in-furnace aerodynamic field was obtained.A comparison of the simulation calculated results with the test ones shows that the calculated data are in relatively good agreement with th...
