| 摘 要： | 利用TG-DTA-FTIR联用技术，测定煤升温氧化过程不同阶段起始温度、吸氧量、放热量、释放气体初温与成分以及燃点等参数，提出了用某个温度下煤的吸氧量或在整个氧化阶段总吸氧量来表示煤的自燃倾向性高低的不合理性；给出了用100~200 ℃温度段的吸氧速率q′T指标进行煤自燃倾向性高低评判方法.

| Abstract: | Introduced the combined technology of TG-DTA-FTIR to measure the following parameters at different phases： the moisture content of coal， the initial temperature， the quantity of absorbed oxygen， the quantity of released heat， the initial temperature and component of released gas and ignition point and so on.Advanced that it is irrational to show the susceptibility of spontaneous combustion of coal with the quantity of absorbed oxygen at some temperature or the total absorbed oxygen at some oxidation phase. Gave the estimated method that showed the susceptibility of spontaneous combustion of coal with the absorbed rate of oxygen （q′T) at 100~200 ℃. |

| Keywords: | combined technology of TG-DTA-FTIR oxidation process coal's spontaneous susceptibility |
