煤炭快速工业分析仪测试条件的研究

研究了测试条件对全自动工业分析仪测定煤炭的水分、灰分、挥发分的准确性,结果表明,气体流速、称样重量等分析结果的影响不大,而称样方式对分析结果影响较大。当采取控制样品在称量温度一致的措施后,仪器的分析精度大为提高。 Has studied the test condition to the completely automatic industry analyzer determination coal moisture,the ash content,the volatility share accuracy,finally indicated that the gas discharge rate,analysis result's and so on name the type weight influences are not big,but said that the quadrat type to analyzes the result influence to be big.When adopts the control sample after the weighing temperature consistent measure,instrument's analysis precision is the enhancement greatly
