摘要
煤粉再燃烧技术是低NOx燃烧技术中经济有效,且较有前途的一种方法,而煤中的矿物质对NOx的还原有催化作用。从原理入手,分析了煤焦中矿物质的种类,存在形态,催化机理以及反应气氛对NOx还原的影响,为进一步研究提供参考。
Pulverized-coal reburning is a economical and easy practical method that is intensively developing in low NO. burning technology, in which the minerals in the coal will catalyze NOx deoxidize. Basedon the principles, the category, existing form, catalysis mechanism, of the coal char mineral, as well as the influence of reaction circumstances on NOx deoxidization, are analysised, to further provide reference for relevant research.
