Abstract

DOI: 10.26471/cjees/2018/013/009

The release ratios of mercury and arsenic during the combustion of two coal gangues with and without addition of CaO were studied at 600-1000°C. The experimental results showed that more mercury and arsenic released from two coal gangue samples with the increase in treatment temperature. At the same temperature, the release ratio of mercury was significantly higher than that of arsenic. The release ratio of arsenic decreased obviously after adding CaO, which indicates that CaO had a significantly inhibition effect on the release of arsenic. On the other hand, the CaO has a limited inhibition effect on the release of mercury during coal gangue combustion because of the release ratio of Hg slightly decreased after adding CaO.
