摘要： 为了确定在不同粒度条件下空气流量对煤氧化程度的影响，通过程序升温法，测定了色连3号矿五种粒径煤样在不同空气流量下O2、CO以及活化能的变化差异。结果表明，0～0.9mm的小粒径煤样耗氧量对空气流量变化反应较为敏感，且小粒径低空气流量的煤样反应活化能最低|在干裂温度120℃前后空气流量不同，CO产生速率会出现突变点。
关键词: 程序升温, 空气流量, 煤粒径, 活化能
Abstract: This paper compare the changes of O2, CO and activation energy of five kinds of Se Lian coal samples under different air flow by temperature programming. The experimental result indicated that the oxygen consumption of 0-0.9mm small size coal sample more sensitive about the air flow change, and small size coal sample with low air flow rate have minimum activation energy. Different air flow will rise a turning point of CO production rate at the cracking temperature about 120℃. This paper have a positive instruction to determinate the coal spontaneous combustion and the air flow rate of coal at low temperature oxidation experiment.
