摘要
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 prime T) at 100 - 200°C.
