摘要

通过分析中速磨煤机入口一次风量测量误差原因

采用分风道测量来改善通过风道型文丘里管内介质流态和调整温度测点位置的方法

达到了消除测量偏差的目的

Abstract

The causes of inlet primary air flow measurement error occurred on medium speed coal mills are analysed. Two methods have been used for eliminating the said measurement error

the one is application of sub-duct measurement to improve the medium flow condition in air-duct type venturi-tube

and the other is adjustment of measuring points position. In this way

the goal of eliminating said measurement error is achieved.
