摘　　要：在沉降炉中进行了石灰石的脱硫特性研究。表明用20%O2+80%CO2的混合气体作助燃气时比用空气作助燃气时有较好的脱硫效果,并能减少NOx的排放,是一种新的能同时控制CO2,SO2和NOx三种污染物的好方法。The desulfurization characteristics of pulverized limestone have been studied with the help of a drop-tube furnace. Tests show that a combustion assisting gas mixture of 20% O2 and 80% CO2 is not only more favourable for desulfurization than air, but in addition helps to diminish the emission of NOx and is thus helpful for simultaneously getting the three pollutants i.e. CO2, SO2 and NOx, under control.
