摘要
采用数值模拟的方法,对高温空气多级点火燃烧器进行数值试验研究。模拟结果大致反映了该燃烧器内煤粉气流的分级着火过程。同时针对原结构燃烧器一级筒内存在的煤粉颗粒轨迹贴近底部壁面的问题,提出优化结构,并运用数值模拟方法确定优化方案。
Numerical simulation method is used to investigate the high-temperature air ignition multistage combustor. The process of pulverized coal ignition in every stage can be imaged from the simulation results. The former combustor has the problem that coal particles abrade the bottom wall in the first stage barrel, and the solution of this problem using the simulation method is given.
