摘要:
为了探讨TG实验过程不同实验条件对煤氧化燃烧特性的影响,采用控制变量法对不同煤样粒度、不同升温速率、不同试样量条件下煤氧化燃烧过程进行了研究。通过TG/DTG曲线上的特征温度点将煤的氧化燃烧过程划分为五个阶段。结果表明:煤样粒度增加、升温速率增大都会使TG曲线向高温侧移动,对应的各特征温度值也都会升高;随煤样量增加,TG曲线在受热分解段及燃烧阶段向低温侧移动,煤样着火点温度T4降低。
Abstract:
In order to investigate the effect of different experimental conditions on the oxidative combustion characteristics of coal in the process of TG experiment, control variable technology was used to research the oxidative combustion process under different size, different heating rate and different sample quantity. The process was divided into five stages according to the characteristic temperature on the TG/DTG curves. The results showed that: with the increase of coal particle size and heating rate, TG curves move to the high-temperature side, each of the corresponding characteristic temperature value also increases; with the increase of coal sample quantity, TG curves move to the low-temperature side in thermal decomposition stage and combustion stage, and the coal ignition temperature T4 decreases.
