大同烟煤增压富氧燃烧过程中硫、氯和氟的析出特性
Investigation on sulfur, chlorine and fluorine releasing characteristics during pressurized oxy-fuel combustion of Datong bituminous coal
摘要
Abstract
The release behavior of sulfur, chlorine and fluorine during pressurized oxy-fuel combustion was investigated by a pressurized thermogravimetric analyzer ( PTGA) combined with Fourier transform infrared ( FT-IR) spectroscopy, in which the influence of presus re on the rle ease cha racteristics was mailn y focused on.The results show that the changes in pressure have a remarkable effect on the mgi ration and transformation of sulfur, chlorine and fluorine.The conversion of pyrite to COS increases with the rise in pressure, which leads to an increase in SO2 yield, but at 3 MPa, the SO2 yield drops somewhat.Besides, the increase of CO partai l pressure at higher rp essure promotes the COS generatoi n, leading to an increase in COS yield.Beac use the release of chlorine is close reltae d to the volatile yield, thei ncrease of volait le yield at higher pressure makes more orgnai c chlorine release and conversion to HCl.Moreover, the ne hanec d burning rate and combustion tempre ature by volatiles at higher pressure accelerate the mineral fluorine resolving, and more HF is formed.Also, the hydrolytic reca tions are strengthened at higher pressure, which results in an incresa e of HF yield.关键词
