摘要
为了弄清楚高炉内未燃烧煤粉(简称UPC)对焦炭性能的影响,我们在实验炉内做了纯焦炭恒温处理,气化反应以及焦炭层喷吹UPC后气化反应一小时后焦炭样的粉化情况,得出的主要结论:(a)同一温度条件下,纯焦炭气化反应一小时粉化最严重,而焦炭层喷吹UPC后粉化程度降低;(b)同一温度条件下,随着焦炭层喷吹UPC量的增加,气化反应后焦炭的强度提高,粉末量减少。
In order to clarify the effect of unburnt pulverized coal (UPC) on coke pulverization properties. A series of fundamental experiments were carried out at laboratory furnace. The main results obtained are as follows: (a)Under the same temperature,coke fines increases remarkably with the progress of gasification for an hour, but after UPC was injected into coke layer, coke fines decreases; (b) Under the same temperature, Strength of coke increases after the reaction and coke fines decreases as the amount of UPC being injected into coke layer increases.
