摘要
采用正交试验法,考察影响准确分析煤质发热量的因素(充氧时间、样品重量、苯甲酸纯度、内外简水温之差),并进行准确度、精密度验证。其测定结果均满足要求。
Adopting cross tests, this paper investigates the factors influencing the heating value of coal, such as oxygen supplying period, sample weight, purity of benzoic acid and the temperature difference of water inside and outside of the barrel.The accuracy and precision of the test are verified, The test results are within the error of Chinese Standard.
