燃煤硫污染及固硫研究

Study on SO_2 Pollutant from Coal Combustion and Fixed-sulphur Technology

从理论上探讨了在煤的燃烧过程中ＳＯ＿２的生成机理以及减少燃煤ＳＯ＿２污染的途径，并在此基础上，对影响燃煤固硫效益的主要因素——钙硫比，炉内温度，燃烧时间，固硫剂等进行了初步实验研究，确定了钙硫比的最佳值，掌握了固硫的规律，给出了废渣固硫剂的利用原则。

This paper discussed the technologies for the control of the emission of sulphurdioxide (SO_2) from the combustion of coal,The fixed-sulphur technology proved to be themost efficient.Simultaneously,the effect of the main parameters(i.e.calcium-sulphur ra-tio,temperature,combustion time,fixed-sulphur sorbent , etc.)on the fixed-sulphur effi-ciencv was studied as well.
