【摘要】 选取SiO2、Al2O3、Na2O、Fe2O3和CaO等5种成分作为实验样品的组成成分。利用国标GB/T219-1996的方法观测样品的熔点,分析CaO对其他4种成分熔融特性的影响。得出CaO具有助熔的作用,是组成低熔点共熔体的重要组成部分的结论。采用这一规律可以改变和控制煤灰的熔融特性,从而优化锅炉运行。更多还原

【Abstract】 Silicon dioxide, alumina, sodium oxide, ferric oxide and calcium oxide make up of the experimental materials. Sample’s melting point is to be observed according to the method of GB/T219-1996. Calcium oxide’s influence on the melting characteristic of the main materials in the coal ash is to be analyzed through melting point. The conclusion is that calcium oxide is a kind of matter, which can assist others to melt. This can change coal ash’s melting characteristic, and the merit can optimize boiler’s running.更多还原
