Desulfurization Performance Study on Many Kinds of Load-Modification Fly Ash

Sulfur dioxide is a kind of toxic and harmful gas, and will pollute atmosphere environment if exhausted directly. There are a lot of desulfurization methods so far. The desulfurization efficiency including many kinds of fly ash containing bag dust remover, electric dust remover and wet dust remover mixed with calcium hydroxide in the same mixture ratio, same hydrogen temperature and same hydrogen time is studied in this paper. The results indicate that the desulfurization efficiency between the modification fly gas with bag dust remover and with electric one is similar, and they are more efficient than wet dust remover, but less efficient than activated carbon. Meanwhile, the desulfurization mechanism of modification fly gas is analyzed briefly in this paper.
