燃煤电站飞灰中含碳量的测量

MEASURING CARBON CONTENT OF FLYING ASH FROM COAL BURNING POWER STATION

研究了用低能Υ射线反散射方法测量燃煤电站飞灰中含碳量的可能性。建立了含碳量与反散射强度关系的表达式。实验标定误差小于±0.55％。分析了产生误差的原因。

This paper studies the feasibility of measuring the carbon content of flying ash from coal burning power station by low energy gamma rays back-scatterring technique,An expression has been established for the relation between the carbon content and the back-scatterring intensity. Experimental calibration error is less than ±0,55％ (lσ). The sources of error are discussed.
