原煤样燃烧热的测定研究

The raw coal sample determination of the heat of combustion research

利用XRY-1A型氧弹式燃烧仪的原理和装置，通过标准物质苯甲酸对仪器的水当量W’的测定，计算得原煤样的燃烧热。实验结果表明．标准物质苯甲酸和原煤样均能燃烧完全，燃烧成功率达98％；雷诺校正图处理后，原煤样的燃烧热为-17．91KJ／g（文献值-26．54-27．92KJ／g），较文献值低。

Using XRY - 1 type a principle and device of oxygen bomb combustion type instrument, through standard material benzoic acid to measuring instrument of water equivalent W ＇calculated heat of combustion of coal sample. The experimental results show that the standard material benzoic acid and raw coal sample can complete combustion, burning the success rate of 98%; Renault correction chart after processing, the heat of combustion of coal sample for -17.91KJ/g （the literature value of 26.54--27.92 KJ/g）.
