摘要
通过试验和数理统计分析,对煤工业分析中灰分的测定方法进行了改进探讨,并采用煤样灰分曲线实验对改进的条件进行论证。论证结果表明,改进条件下工业分析测定结果的准确性和重现性均良好。
Improvement of ash content determination in proximate analysis of coal are discussed by test and mathematical statistics analysis.The conditions of improvement are proved by means of ash content curves test of coal.It showed that accuracy and repeatability of determination results in proximate analysis are good under the condition of improvement.
