煤燃烧特性的EGA与TGA法比较研究

Contrasts between gas release and thermogravimetric analysis on coal combustion characters

为了研制出能够在研究煤的燃烧特性方面替代热重分析仪而成本又低廉的煤质分析仪器 ,通过研究煤样在热重分析条件下着火、燃烧直至燃尽期间的CO2 质量变化规律 ,得出了采用检测煤样燃烧时CO2 气体生成的变化情况同样可判断出煤样燃烧特性的结论 。

To develop a new apparatus with low cost, the author studied the CO 2 evolvement rules during coal combustion by means of thermogravimetry analysis. It is concluded that coal combustion characters can be estimated after the rate of CO 2was engendered and a theoretic basis for the new apparatus is provided.
