✦ Synopsis

Fly ash was used as an additive, and the effect of it on desulfurization by lime at 400Β±8008C was studied experimentally. The conversion rate of Β―y ashΒ±lime to calcium sulfate was found to be greater than that when using lime alone. One reason is that Β―y ash can act as a support medium for lime, thereby increasing its dispersion and extending its effective reaction surface area. Fly ash with a high iron or its oxides is likely to have some ability to absorb particles of lime on its surface.
