【摘要】 以水泥分解炉为对象,分析了分解炉内NOx产生与分解机制,采用数值模拟方法对分解炉内NOx生成还原过程(燃料N析出、挥发份NOx生成、焦炭NOx生成、NOx同相还原、NOx异相还原)进行了模拟研究,并开发了分解炉NOx生成与还原模拟计算机辅助试验平台,为低NOx分解炉的设计开发及运行调整提供了理论分析工具。更多还原

【Abstract】 The process of NOx formation and reduction in cement precalciner was analyzed,and the mathematical models(fuel nitrogen emission dynamics,volatile-NOx formation dynamics,Char-NOx formation dynamics,homogeneous deoxidize dynamics and heterogeneous deoxidize dynamics) were used to simulate the process of NOx formation and reduction in precalciner.Based on these works,the numerical simulation method was combined to develop the Computer Aided Test Platform for NOx Simulation in Precalciner,which could provide an experimental platform for design and development of low-NOxprecalciner.更多还原
