用固体吸附剂控制燃煤重金属排放及其对SO_2、NO_x的影响

STUDIES ON EXPERIMENTS OF USING SOLIDSORBENT TO CONTROL HEAVY METAL DURING COAL COMBUSTION

用石灰石、硫酸钙、铝土矿对燃煤重金属排放进行控制，发现三种吸附剂对某些有毒重金属有吸附作用，吸附效率与吸附剂种类、粒径大小有关。同时添加吸附剂后对ＳＯ２。

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
