摘要

利用一维热态实验炉分别对不同粒度煤粉燃烧时

NOx 排放特性随煤种、过量空气系数、温度的变化规律进行了研究。研究结果表明 :NOx 的排放浓度与煤粉粒度存在一个煤粉粒度临界值

当煤粉粒度小于临界值时

随煤粉粒度的减小

NOx 的排放浓度减小 ;当煤粉粒度大于临界值时

随煤粉粒度的减小

NOx 的排放浓度增大 ;煤粉超细化后

褐煤、烟煤的NOx 的排放浓度明显减少

贫煤、无烟煤则变化不大。

Abstract

The regularity of NO

emission performance along with coal sort

excess air ratio and temperature variation during combustion of different particle size for pulverized coal in onedimensional hotstate experimental furnace has been respectively studied. Results of study show that there is a critical value of pulverized coal particle size existing between NO

emission concentration and the said particle size. When the said particle size to be smaller than the said critical value

the NO

emission concentration to be reduced along with reduction of the particle size; when the particle size to be greater than the said critical value

the NO

emission concentration to be increased along with the reduction of the particle size. After the pulverized coal being ultrafinely subdivided

the NO

emission concentration for brown coal and bituminous coal is obviously reduced

but for lean coal and blind coal

the variation of NO

emission concentration to be very small.
