摘要/Abstract

摘要：

介绍了氨法脱硫的原理、主要的脱硫工艺以及实际应用情况。实践表明，大型锅炉采用氨法脱硫效率高，投资省，用电量少，可生产硫酸或硫酸铵。烟气即使不降温，直接进入脱硫塔，也可达到较高的脱硫效率。通过对多种工艺的比较，为燃煤烟气脱硫技术的选择提供参考。

Abstract:

The principle, main desulphurization process and actual application of the desulphurization by ammonia are described. Practice shows that the desulphurization by ammonia for large capacity boilers is characterized by high efficiency, less investment and less electric power consumption, and sulfuric acid or ammonium sulfate can be produced. Even if the temperature of flue gas is not reduced and it is sent directly into desulphurization tower, the higher desulphurization efficiency can be obtained. Through the comparison of many kinds of processes, a reference is provided for the selection of flue gas desulphurization technology for coal firing.
