摘　　要：针对一种强引射放空火炬,应用Fluent软件对辅助引射器和火炬头的流动特性进行了数值模拟研究。基本型计算表明,辅助引射器的引射系数为3.25,火炬头的引射比为0.77。正交分析表明,辅助引射器优化参数组合为:混合管道扩张角4°、喉部环空间隙7.5 mm、燃气入口直径7 mm、空气入口直径60 mm,优化结构引射系数为6.30;火炬头优化参数组合为:筒体扩张角7°、防风罩间隙207 mm、辅助引射器数量8、主放空管深度242 mm,优化结构引射比为0.89,引射性能提高16%。Regarding the release flare with strong ejection,the Fluent software was adopted to simulate flow characteristics of the auxiliary ejector and flare head.The basic model calculation shows that,the auxiliary ejector’s ejection coefficient is 3.25,and the flare head’s ejection ratio is 0.77.Orthogonal analysis of the auxiliary ejector’s optimum structural parameters indicates that,the parameter combination are as follows:a 4°mixing pipe expansion angle,a 7.5 mm throat annular space gap,a 7 mm gas inlet diameter,a 60 mm air inlet diameter and a 6.30 ejection coefficient of the optimized structure.The optimized parameters of the flare head are as follows:a 7°cylinder expansion angle,a 207 mm wind shield gap,8 auxiliary ejectors,a 242 mm depth of main vent pipe,a 0.89 ejection ratio of the optimized structure and a 16%injection performance increased.The research results provide a useful exploration for increasing oxygen to improve combustion efficiency and reduce the generation of black smoke in the flare.
