| 摘 要： | 研究了合山煤在O2 /CO2 方式下SO2 的生成特性 .结果表明在O2 /CO2 方式下 ,由于燃煤的燃烧特性和钙基吸收剂的煅烧分解特性不同于传统燃烧方式 ,SO2 的生成速度加快 ,生成量较空气气氛下大为减少 ,钙基吸收剂的脱硫率随温度升高而增加 ,表明O2 /CO2 方式有利于钙基吸收剂高温脱硫

| Abstract: | Systematical experiments on the emission of SO 2 of Heshan coal under different conditions are carried out. Compared with conventional air condition, the results show that SO 2 releases faster and the emission of total quantity of SO 2 decreases due to different combustion characteristic and chemical reaction of coal in CO 2/O 2 mixer. The results suggest that the desulfurization ratio of calcium based sorbent at high temperatures is more efficient in CO 2/O 2 mixer. |
