Study on the effect of Mg~(2+) and Na~+ on the fusibility of coal ash with high ash fusion point

Adjustment of coal ash fusibility of high fusion point coal has been attracted by attention of many researchers in coal gasification and combustion.The effect of Mg2+ and Na+ on the fusibility behavior of the high fusion temperature coal ash from Yangquan Guzhuang was studied in this paper,using the method of adding different amount of MgO and Na2CO3(5%~25%) to the coal ash.The result shown that the ash fusion temperature monotonically decreases...
