Research on the Physical and Chemical Properties of Coal Ash Drained off from Yuntianhua Group Co.,Ltd |

| Abstract: | In this paper,the physical and chemical properties of coal ash drained off from power plant of Yuntianhua Group Co.,Ltd., were systematically tested by modern analytic technology.Higher content of Fe 2O 3 is a character of chemical properties of Yuntianhua coal ash,residual carbon has a lower content.The components of mineral phase are not complex,but mullite are not discovered which formed at the high temperature,and tiny glass pearls are also hardly existed.The particle of coal ash appears as abnormal crumb figure and the average granular diameter is minute,leading to higher water demanded ratio.The kinds of microelements and radioelements are abundant,which fit the national standard and will not pollute environment. |
