摘要
首先对粉煤灰的化学组成及火山灰特性做了说明,并简单介绍了利用粉煤灰脱硫脱氮原理.利用粉煤灰进行燃煤烟气净化时,具有工艺简单并能同时脱硫脱氮的优势.列举了几种利用粉煤灰脱硫及同时脱硫脱氮工艺.但是粉煤灰作为脱硫脱氮剂的反应机理尚不很明确,且在实际工程中应用效果不很理想,因此粉煤灰的利用尚需大量的实验研究.
This paper introduces the chemical composition and pozzolanic characteristic of fly ash. And the principle of desulfurization and denitrifaction of fly ash is introduced. It has advantages of simple craftwork and removalling SO2 and NOx simultaneously in the coal fired flue gas treatment. This paper particularizes several technics of desulfurization and denitrifaction. But it is not very clearly of fly ash as absorbent and its effect is not very good in the practical application. So it is necessary to study the application of fly ash further.
