三节炉测定煤中碳氢的影响因素分析

The Analysis of Influence Factor of Carbon Hydrogen Determination in Coal by Three Sections of Furnace

三节炉法是测定煤中碳氢值的重要方法。文章对三节炉测定煤中碳氢值的原理进行了阐述,对三节炉法测定煤中碳氢值的影响因素进行了分析,讨论了温度、气路系统、燃烧管的填充、空白值、煤样载体对碳氢值的影响。测定了煤样载体对五种煤样的碳氢值的影响。对碳氢值的测定有一定的指导意义。

It was an important method to measure the value of the carbon -hydrogen in coal by three sections of fur- nace. The principle of three sections of furnace method for the determination of carbon - hydrogen values in coal was ex- plained, and some influence factors in the carbon - hydrogen measurement of the coal were analyzed. The influence of temperature, gas path system, combustion tube filling, blank value, and coal carrier of hydrocarbon values were dis- cussed. The influences of coal carrier to five kinds of coals were measured. There was a great significance in improving the accuracv of carbon - hvdrozen values.
