| Abstract: | Limestone, CaSO 4 and bauxite are used to control heavy metals during coal combustion Absorbing efficiency is related to the sort and size of absorbents The test shows that CaO can reduce the emissions of Cd, Pb and Ni, CaSO 4 can absorb Cd, Pb, Co and Cu and bauxite can reduce all the five heavy metal elements The effects of adding absorbents to coal on the emissions of SO 2 and NO x are also considered |
