Pressure oscillation characteristics of n-butanol/kerosene mixture in non-premixed combustor

  • 摘要: 为探索生物混合燃料在燃气轮机燃烧室内的应用,将丁醇掺混入航空煤油中,根据燃烧室的实验结果构建熵波对流模型,定量分析其不同体积分数对燃烧室内压力振荡频率的影响。实验结果表明:在燃烧室进口压力1.98 MPa、温度600 K和油气比0.03下,随着丁醇所占体积分数增大,燃烧室内压力振荡频率逐渐下降,而幅值变化无明显规律。熵波对流模型结果与实验吻合较好,通过分析表明,不同燃料组分热值变化引起的对流时间改变,是燃烧室压力振荡频率变化的主要原因,为控制燃烧室内压力振荡提供了参考。
