燃气轮机燃烧过程中污染物的生成机理
, PP. 10-15
Keywords: 燃气轮机,预混燃烧,化学反应动力学,污染物,生成机理
Abstract:
提出了一种新的适用于燃气轮机燃烧过程中污染物生成预测的化学反应机理,包含25种组分,75个基元反应。在激波管和预混燃烧条件下对该化学反应机理的着火延迟时间、火焰速度及反应物、主要中间产物及污染物生成特性进行了预测。结果表明,新机理预测结果与相关实验值及详细机理预测结果吻合较好，为化学反应动力学模型与多维cfd模型耦合计算燃烧和排放特性提供了可行途径。对燃气轮机燃烧室化学网络模型的分析结果表明，在贫燃预混燃烧条件下,zeldovich与n2o生成机理在no的形成过程中起主导作用。
