Study on Mechanism of Desulphurization of Coal Water Slurry in Flue

摘要：

There is 30 percent of water in coal water slurry, and it contributes to the reaction between desulfuzrizers and sulfur dioxide which form sulphate and also reduces the sulfur dioxide emission. These reactions vary from each other a lot due to the distinctions of flue gases temperatures which decreased sharply when passing through the dust cleaner. Before entering the cleaner, the flue gases temperature is above the dew point, thus the water vapor can enhance the activity of the desulfurizers and pulverize them efficiently as well. After the cleaner, however, the temperature fall below or draw near to the dew point, and thus it would produce water drops or liquid film inevitably. Most of the desulfurization reaction is ion reaction in liquid state.
