1) Ratio of the Lean and the Rich

燃料浓淡比
4) rich-lean combustion

浓淡燃烧
1.
Through the whole pre-mixed,adapting the ratio of N2,rich-lean combustion and so on,the result is that increasing the ratio of N2 and rich-lean combustion can successfully reduce the thermal NOx emission compared to the whole pre-mixed combustion,because of the major effect factors temperature and density of [O2],and there is a optional ¢r between 1 and 2 in rich-lean combustion.
通过完全预混合、预混合调整N2比例、浓淡燃烧等方法分别进行了数值模拟,结果表明:由于温度和氧气浓度是影响热力型NOx生成的主要因素,组织浓淡燃烧和增加N2比例能够达到降低热力型NOx生成的良好效果,并且组织浓淡燃烧,在¢r=1~2之间存在一个最优值。
