摘要
利用高分子选择性气体分离膜对空气进行分离，从而得到含氧量≥28％的富氧空气用于工业燃烧，是一种节能效果好、经济效益高、可较少环境污染的高效燃烧技术。但是，这一燃烧新技术在应用最为广泛的动力机械－内燃机上却基本未得到研究和应用。本文通过对气体膜分离原理和内燃机燃烧过程的分析、研究，论证了富氧燃烧技术在内燃机燃烧中的应用可行性及其在内燃机节约能源、减少排污、提高性能等方面所存在的优越性。
The oxygen-enriched combustion is a new type of efficient combustion technique of low emission and energy consumption. In this technique, macromolecular membranes are used to conduct selective separation of air in order to produce oxygen-enriched air (the oxygen content greater than 28%) for industrial combustion processes. Based on a thorough analysis and investigation of the fundamentals of the macromolecular-membrane separation technique and the combustion process in diesel engines, the engineering feasibility of applying the oxygen-enriched combustion technique to diesel engines was discussed in detail in this presentation. It was concluded that applying this new combustion technique will improve the performance of diesel engines, reduce emissions and energy consumption.
