针对准二维狭缝燃烧系统,进行了扩散燃烧、预混燃烧、空气部分预混燃烧以及稀氧部分预混/富氧补燃(ODPP/OESC)等燃烧技术的排放特性对比;并进行了稀氧部分预混/富氧补燃技术中不同预混氧浓度、不同补燃氧浓度、不同预混当量比以及不同补燃位置火焰的燃烧特性以及污染物的生成特性的对比分析.研究结果表明,ODPP/OESC的燃烧工艺,能够有效地实现燃烧过程中高效率和低排放的双优化,随着预混当量比的增大以及后期补燃位置的增大,快速型NOx生成比重明显增大.“,”A quasi-two-dimensional slit jet experimental diagnostic systems are constructed used to explore emission characteristics of different combustion technologies which include diffusion combustion,premixed combustion,partially premixed combustion and oxygen-diluted partially premixed/oxygen-enriched supplemental combustion.Combustion and emission characteristics are researched about the different conditions of ODPP/OESC.The results show that ODPP/OESC could achieve high efficiency and low emissions.With the increase of premixed equivalence ratio and the afterburning position,the proportion of the prompt NOX generation capacity significantly increases.
