摘　　要：某台1000MW超超临界锅炉燃烧器的布置对(NOx)的影响,在燃烧调整过程中,通过改变燃烧配风,调整煤粉分配浓度,得出煤粉燃烧器出口煤粉浓度、燃烧器分级配风比例对(NOx)排放规律的影响,为燃煤锅炉采用浓淡分离和分级燃烧技术实现低(NOx)燃烧奠定了基础。The influence of burner arrangement to NOx emission for the 1 000 MW ultra super critical boiler. During the combustion commissioning, by changing the combustion air distribution, PF con- centration get the relations of the OFA ratio to NOx emission, Establish the foundation of achieving low- NOx combustion with the technic of rich- lean combustion and staged combustion.
