摘要
根据GB/T212—2008《煤的工业分析方法》中的规定,在测定挥发分时,通过实验对比,无烟煤中水分随着煤的变质程度加深而呈规律性变化。从泥炭、褐煤、烟煤到年轻无烟煤水分逐渐减少,从年轻无烟煤到老年无烟煤的水分又逐渐增加。由于煤中水分过高和煤的氧化增重,导致挥发分测定值产生负值,影响挥发分的测定结果。
High analyzing water content and oxidation weight growth of coal samples lead the numeric values of to be negative. In response to this situation, Analyze the factors that affect the determination of volatile matter and put forward a series of solutions.
