热探针法测定烟草导热系数的实验研究

Experiment Study on Measuring the Thermal Conductivity of Tobacco by Heat Probe

烟草的霉变炭化是烟草储存过程中主要敌害之一。烟草的燃烧与其他可燃物的燃烧有所不同 ,主要以阴燃为主 ,烟堆垛或烟捆、烟包在一定的温度、湿度下内部就会阴燃炭化 ,并逐步扩大 ,造成不必要的浪费和损失。烟草内部阴燃扩展过程中热传导起主导作用 ,烟草的导热系数是非常重要的参数。文章介绍了用热探针法测量烟草导热系数的原理和方法 ,该方法可直接用于烟草企业对烟草导热系数的测量。

It will make the tobacco mildew during a long storage in some environment. Smolder is main combustion form of tobacco. In ill storage condition, the inner of tobacco bales will mildew then smolder. The conduction is important in the progress of smolder development from tobacco inner. In the article, we gave the theory and methods of measuring the tobacco conduction coefficient by heat probe.
