锥形量热计研究木材临界辐射能流和点燃温度

Using cone calorimeter to study timber’s critical heat flux and ignition temperature

锥形量热计不但可以直接测量出材料的某些燃烧特性数据(如热释放速率、质量损失率、点燃时间等),而且可以根据所测得的数据间接得出材料的其它燃烧特性数据。笔者介绍了一种从锥形量热计测得的数据推导临界辐射能流和点燃温度的方法。

Cone Calorimeter can not only directly determine some flammability properties of materials such as heat release rate, mass loss rate, ignition time and so on, but also can indirectly educe other flammability properties of materials based some determined data. This article recommends a method which can deduce critical heat flux and ignition temperature from the data determined by cone calorimeter.
