摘要
通过实验分析曹妃甸港堆存的3种不同煤质吐哈煤在70d内发热量、挥发分的变化情况,判断其氧化趋势.实验表明,挥发分随储存时间延长没有明显减小的趋势;发热量随储存时间延长有明显减小的趋势,且在30～40 d内下降幅度最大,各粒度级的氧化趋势没有明显区别.
Abstract
In order to determine the oxidation trend,the changes in calorific value and volatile content of three kinds of Tuha coal with different coal qualities stored in Caofeidian Port were analyzed by experiments.The experimental results show that the volatile matter has no significant decreasing trend with the extension of storage time.The calorific value decreased significantly with the extension of storage time;and the decrease was the largest in 30 to 40 days,while there was no significant difference in the oxidation trend of each particle size.
