煤质工业分析仪校准方法

The Calibration Methods of Proximate Analyzer For Coal

煤质工业分析仪广泛应用于煤炭的分析检测,为了评估其计量性能,需要对其进行校准,但目前没有国家校准规范或检测方法。现根据煤质工业分析仪的性能特点,提出了控温性能,灰分、挥发分示值误差和重复性,以及外观、绝缘电阻和绝缘强度等通用技术要求的校准方法。实验证明该方法可以较为全面地对煤质工业分析仪计量性能进行评定。

Proximate analyzer for coal is broadly used for determination of coal,so it is very important to evaluate its performance,orderly,the calibration of the proximate analyzer is needed. But there is no national calibration specification or test method at present. On the basis of the function characteristics of proximate analyzer for coal,the authors have suggested the calibration methods of temperature control performance,indication error and repeatability of ash and volatile,and the general technical requirement which includes appearance,insulation resistance,and insulation strength. The experimental results prove that this method can comprehensive evaluate the metering performance of the proximate analyzer for coal.
