煤粉再燃煤焦异相还原NO_X的影响因素分析

Analysis of influential factors on NO_X heterogeneous reducion by char in coal reburning technology

煤粉再燃烧技术是低NOX燃烧技术中正在发展的较有前途的一种方法。本文从再燃烧降低NOX原理分析入手,分析了煤种、煤颗粒粒径、热解条件、反应条件、煤中金属氧化物等因素对煤焦异相还原NOX的影响及规律,为进一步研究提供参考。

Coal reburning ia a developing successful advanced technology for reducing NO_X in fired coal.Based on the priciple of reburning technology,the main influence factors of NO_X heterogeneous reduction by char,such as coal type,size of coal partiale,devolatilization atmosphere,reaction atmosphere,metal oxides in coal ashes,are analysised.This provides a sound basis for further research of NO_X heterogeneous reduction by coal char.
