压力下各种因素对煤粒着火温度的影响

Effects of Various Factors on the Ignition Temperature of Coal Particles under Pressure

利用自行研制的双炉膛加压热重分析仪进行了 8种煤的加压着火试验。研究了各种因素 ,如煤粒粒径、氧浓度、加热速率、挥发分含量等在压力下对煤粒着火温度的影响 ,得到了一些新的结论。

With the newly designed dual chamber pressurized thermogravimetric analyzer (PTGA) the ignition experiments of eight kinds of coal particles were performed under pressure.The effects of various factors (such as particle size,oxygen concentration,heating rate,volatile content,etc.)on the ignition temperature under pressure is studied experimentally and some new conclusions were obtained.
