摘　　要：对一种普通气体燃烧器和两种采用分级进料技术的新型气体燃烧器进行了燃烧的数值模拟研究,同时进行了数值模拟的可靠性实验。数值计算结果表明,结构差异是燃料气和助燃空气的流场组织不同的原因,表现为不同的燃烧火焰形状及温度分布。模拟结果对于新型气体燃烧器的设计具有指导意义。Numerical simulation was made on the combustion of three kinds of gas burners including a common gas burner and two kinds of new burners used by step-feeding technology. At the same time,the experiment was made to make sure the validity of numerical simulation. The numerical simulation results indicate that the flow of fuel and air varies with different structures, and as the result is the difference of flame shape and temperature distribution. The simulation results can play a directional role in the new design of gas burner.
