无烟煤影响焦炭热性能的试验研究

Study on the influence of anthracite on thermal property of coke

以高炉顶部加入粒煤为背景,研究无烟煤的加入量对不同焦炭反应性和反应后强度的影响。结果表明:高炉顶装无烟煤后,焦炭的反应性降低、反应后强度提高;焦炭气化反应速度和表观活化能均降低。

Discusses the addition of anthracite and the influence of anthracite on the reactivity and the strength after reaction of different coke. The result shows that the reactivity grows lower and the strength after reaction to coke increases. The rate and the apparent activity energy of gasification reaction of coke are lower than that under the condition of no anthracite.
