摘要
采用详细化学反应机理并运用良好搅拌反应器模型,通过化学反应动力学模型的数值计算,就典型的4种天然气组分进行了多种工况下的燃烧特性与NOx排放特性研究。计算结果表明:助燃剂中氧含量对着火时间非常敏感,氧含量较高,着火时间提前;低氧和富燃燃烧方式均可减少NOx排放。
Adopting detailed chemical reaction mechanism and good stirred reactor model,the combustion characteristics and NOx emission of 4 types of natural gas were investigated by numerical simulation using chemical reaction model.The results show that oxygen content in the air is very sensitive to ignition time of natural gas.Also,both the way of low oxygen and rich fuel is effective to decease NOx emission.
