未燃烧煤粉对焦炭粉化性能的影响

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后气反应一小时后焦炭样的粉化情况，得出的主要结；（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。

Effects on Unburnt Pulverized Coal on Coke Pulverization Properties

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.
