| 摘 要： | 为了进一步全面评价O2/CO2煤粉燃烧特性,在前期实验基础上,通过数值模拟方法对空气、O2/CO2两种气氛下煤粉燃烧及污染物形成特性进行数值模拟,从而更充分了解O2/CO2燃煤过程火焰形成、传热和污染物形成特性,以便为合理组织流场、控制温度、获取合理的燃料和氧浓度分布状态及O2/CO2燃烧过程新燃烧器的设计提供必要的指导。

| Abstract: | Based on earlier experiments, this paper compares characteristics of coal combustion and pollutant formation under O2/CO2 atmosphere with conventional air by numerical simulation.It focuses particularly on the combustion fundaments， such as flame temperature, heat transfer, and NOx formations.The results showed that coal combustion under O2/CO2 atmosphere excelled combustion under conventional air.And the obtained data are necessary for reasonably organizing flow field, controlling flame temperature and adopting appropriate O2 concentration, which help to design new oxy-fuel combustor. |
