煤燃烧CO2 O2是与减缓大气中CO2上升相关的几种有前途的新技术之一。在煤燃烧与循环CO2，从系统中排出的NOx的量减少到不到三分之一的空气中燃烧。这一结果与燃料-N向NOx的转化率降低和火焰区再循环NOx的减少有关。CO2浓度、再循环NOx的还原以及燃料-N和再循环NOx之间的相互作用对再循环CO2燃烧系统最终NOx排放的减少的影响已被分离为适当的NOx还原机制。
Coal combustion with CO2O2is one of several promising new technologies associated with mitigating the CO2rise in the atmosphere. In coal combustion with recycled CO2, the amount of NOxexhausted from the system is reduced to less than one third of that with combustion in air. This result is associated with decreased conversion of fuel-N to NOxand reduction of recycled NOxin the flame zone. The effects of CO2concentration, reduction of recycled NOx, and interaction between fuel-N and recycled NOxon the decrease of the final NOxexhausted from the coal-combustion system with recycled CO2have been separated for appropriate NOx-reduction mechanisms.
