氮氧化物排放控制技术分类

摘要

综观国内外NOx排放控制技术，根据其在燃烧过程中产生所处的位置，可分为三类：燃烧前控制技术、燃烧控制技术和燃烧后控制技术。后两者是目前研究和应用最广的NOx排放控制技术。文中详细分析了各种控制技术的原理、NOx清除效率及优缺点等。%According to where the gases are produced, NOx emission control techniques applied at home and abroad can be classiifed into those before, during and after combustion, with the latter two most extensively researched and widely adopted. This paper has analyzed the mechanisms of different NOx emission control techniques, their NOxremoval efifciencies, their advantages and disadvantages.
