摘要
大气中空气动力学直径在2.5μm以下的粒子对人体健康和生态环境的危害性极大,而燃烧过程中产生的烟炱是空气中可吸入颗粒物的主要来源之一。阐述了烟炱生成与排放方面研究的新进展;通过对碳氢燃料在空气中燃烧时烟炱的生成和氧化进行分析,讨论了火焰温度、流场结构等因素对烟炱的生成和排放的影响,为减少高温空气燃烧过程中的烟炱排放量提供了研究基础。
Abstract The inhalable particulate matter in the atmosphere, which aerodynamic diameter is less than 2.5μm, does much harm to human health and the environment. The soot generated from combustion processes is the main composition of the inhalable particulate matter in the air. The latest investigations about soot generation and emission were introduced. The effects of flame temperature, operation parameters and flow field on soot emission were discussed. The results would be benefit to study on decreasing soot emission in the high temperature air combustion.
