摘要: 在实验室中采用管式炉进行不同直径煤粉颗粒的燃烧实验，通过在线实时测量燃烧过程中CO、NO排放浓度，研究富氧气氛下不同煤粉粒径配比对燃烧过程中CO、NO排放特性的影响。实验结果表明，随着煤粉中细颗粒质量分数增大，燃烧时CO峰值随着增大；细颗粒煤粉质量分数增加对NO峰值影响不大；NO总释放量随细颗粒煤粉质量分数增加而降低。
Abstract: The pulverized coal combustion experiments were conducted in the lab-scale tube furnace. The real-time on-line measurement system was adopted to measure the CO and NO emission concentrations during the combustion processes. The effects of different pulverized coal particle diameter ratio on CO and NO concentrations were investigated. The experiment results showed that the peak value of CO concentration increased with the increase of the fine particle mass fraction. The in-creasing of the fine particle mass fraction scarcely affected the peak value of NO concentration. While the total NO emission value decreased with the increase of the fine particle mass fraction.
