| 摘 要： | 分级燃烧对高挥发分煤种以及同一煤种的细煤粉的NOx排放的降低效果更显著;对同一煤种,细煤粉飞灰含碳量较粗煤粉低,而且随着分级程度的增加,细煤粉的飞灰含碳量的增加幅度较粗煤粉小;在一次风喷口安装钝体稳燃器时可提高燃烧效率、降低NOx。

| Abstract: | The experimental results have shown that air-staging combustion has more remarkable effect on NOx reduction of high-volatile coal and fine pulverized coal. For the same coal, the unburned carbon decreased with increasing fineness, and with increasing air staging; for the fine pulverized coal, the increase in unborn carbon in fly ash is lower than for the coarse pulverized coal. It is also observed that the unburned carbonic fly ash and NOx emissions can be decreased by installing a bluff body in the primary air jet. |
