摘　　要：挥发分析出对煤焦燃烧动力学的影响陈鸿，张小可，孙学信，韩才元（华中理工大学煤燃烧国家重点实验室武汉４３００７４）Ｉ．Ｗ．Ｓｍｉｔｈ（ＣＳＩＲＯＤｉｖｉｓｉｏｎｏｆｃｏａｌａｎｄＥｎｅｒｇｙＴｅｃｈｎｏｌｏｇｙ，Ｓｙｄｎｅｙ，Ａｕｓｔｒａｌｉａ）关键词...The mechanisms of volatile evolusion were different when coal combust in oxygen atmosphere and pyrolysis in inert atmosphere. At the first period of combustion, parts of volatile give out and combust homogeneously, residual volatile combust together with char heterogeneously. Physical and chemical changes during combustion eg. changing of activie sites, the volatile in the char, etc, had great effects on the reactivity of chars. Because of these effects,intrinsic active energy of chars raised gradually during the last period of combustion. The intrinsic active energy of a electric carbon which had the similar pore structure with these chars didn't change at the same time.
