基于CO_2气体释放法的煤燃烧特性研究

A new lowcost apparatus used to study the character of coal combustion in place of thermograimetric analyzer was developed based on the CO2 release In order to prove the new idea, CO2 concentration of four coal samples during ignition, combustion and burnout was measured by means of the apparatus developed by the authors The characters of special machanism based on the relation between the temperature and CO2 concentration (tCO2), also the derivative curve DtCO2 were obtained The change of CO2 can indirectly estimate the coal combustion characters

球墨铸铁管锌层质量检测方法比对分析

针对球墨铸铁管锌层质量检测方法国家标准GB/T17456.1-2009不适用球墨铸铁管成品的检测和球墨铸铁管成品锌层质量检测的迫切需求,通过文献调研和检测实践,介绍了几种常见的球墨铸铁管锌层质量的检测方法原理、过程及设备,进行了检测实践并对检测结果进行了比较分析,建议在修订球铁管锌层质量检测国家标准中纳入相关检测方法,为球墨铸铁管成品的锌层质量检测提供依据。

煤燃烧特性的EGA与TGA法比较研究

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 。
