摘　　要：试验研究了不同一次风速和煤粉质量分数条件下微油点火燃烧器一级燃烧室的点火性能.研究结果表明,燃烧室中心温度随一次风速和煤粉质量分数的增加,呈先降低后增加的趋势;燃烧室中心线上的CO体积分数随一次风速的增加而增大,但随煤粉质量分数的增加而减小;燃烧室出口中心处的NOx体积分数随一次风速和煤粉浓度的增加则均呈现上升趋势.The primary combustion chamber ignition performance of tiny-oil ignition burners of different primary air velocity and pulverized coal concentration was studied.The results showed that the center temperature of the combustion chamber decreased at the beginning and increased with the increase of the primary air velocity and pulverized coal concentration.The center concentration of CO increases with the increase of the primary air velocity,but decreases with the increase of pulverized coal concentration.The center concentration of NOx increases with the increase of both primary air velocity and pulverized coal concentration.
