摘要
研究了合山煤燃烧过程中挥发分的析出机理，并与惰性气氛中煤的热解机理进行了比较，发现两者是有所不同的。计算了残焦的反应性，结果表明残焦反应性与成焦条件有关，并且在煤焦的整个燃尽过程中是变化的，这种变化与焦中残存的挥发分、活性基等密切相关。
The evolving mechanism of the volatile during the combustion of Heshan-produced coalis studied. And compared with that of the pyrolysis of Heshan-produced coal in an inert at-mosphere. It has been found that they are different.Experiments were performed in a droptube furnace. The reactivity of the residual char has been calculated.It is shown that the re-activity is heavily dependent on the forming conditions of the char and it varies during thecombustion; Owing to the variation of the residual volatile and active radical.
