煤干馏过程中膨胀行为的研究

Research of expansion behavior in coal carbonization process

对7种单种煤进行膨胀行为试验,结果表明单种煤在干馏过程中有两段膨胀行为,黏结性越差的煤膨胀性能越小,胶质层最大厚度Y值和膨胀性能最大值呈正相关关系。

This paper conducts experiments for expansion behavior of 7 types of individual coal,and the result shows that there are two stages of expansion behavior for individual coal in carbonization process. The poorer is the caking property of coal,the lower is the coal expansion property. There is a positive correlation between the maximum thickness Y value and the expansion property.
