两大矿区准东煤结渣和沾污特性对比研究

A Comparative Study on Slagging and Fouling Characteristics of the Coal from Two Major Zhundong Mining Areas

通过燃烧试验研究了五彩湾矿区与将军庙矿区准东煤的结渣和沾污特性,结果表明五彩湾煤灰中Ca含量较高且较易结渣,将军庙煤灰中Fe含量较高且较易沾污,在燃烧利用中应区别对待。

Combustion experiments were conducted on the Zhundong coal respectively from Wucaiwan mining area and Jiangjunmiao mining area to study their slagging and fouling characteristics.Results show that the content of Ca in Wucaiwan coal ash is relatively high,and the coal has high tendency of slagging;whereas the content of Fe in Jiangjunmiao coal ash is relatively high,and the coal has high tendency of fouling.Above two kinds of coal should be treated differently in actual applications.
