An analytical study and numerical simulation of the pyrolysis chemism and the release of volatiles of micronized coal, accompanying NOx reduction during its recombustion in EFR, has been conducted.

对立式管式携带炉内再燃还原NO过程中超细煤粉热解化学机理及挥发份的释放进行了值模拟研究。

The calculation of carbon content of unconsumed pulverized coal in the dust under different PCI rate was carried out based on microscopic and chemical analysis results.

据岩相显微化学的结果,计算了宝钢高炉不同煤比操作条件下,炉尘中未消耗煤粉中的碳含量。

Increased reaction time, smaller coal particle size and increased reburn fuel fraction lead to higher NO reduction rate.

所以,在使煤粉成为超细粉的基础上,利用低挥发烟煤作为再燃燃料是具有可行性的。
