| 摘 要： | 以石灰石为脱硫剂在粉粒喷动床内的半干湿法烟气脱硫是一种新的烟气脱硫过程。本文研究了操作条件对烟气脱硫效率的影响。结果表明，随着Ca/S的增加、饱和接近度及石灰石粉体直径的减小，烟气脱硫的效率提高。考虑到石灰石较之消石灰作为脱硫剂在价格和来源上的优势及本烟气脱硫过程所取得的较高效率，以石灰石为脱硫剂在粉粒喷动床的半干湿法烟气脱硫是一种可提供的烟气脱硫过程。

| Abstract: | We tride to use limestone to remove SO_2 from flue gas in a new semidry FGD process with a powder-particle spouted bed since limestone is more easily available and several times cheaper than hydrated lime. This paper reported the effects of operating parameters on SO_2 removal. The experimental results showed that SO_2 removal efficiency of limestone was considerably enhanced in the present process by increasing Ca/S molar ratio and decreasing the approach to saturation temperature and sorbent size. Thus, the present process with limestone as SO_2 sorbent may be an attractive alter native to other FGD technologies in terms of removal efficiency, price and availability of sorbent. |
