| 摘 要： | 燃烧过程中煤氮的热迁移特性决定着NOx的生成与最终排放量,并对控制和治理燃煤过程中NOx污染具有重要指导意义。将煤氮的热迁移过程分为挥发分氮及焦炭氮2个不同热迁移路径进行讨论,归纳了在燃烧过程中挥发分氮及焦炭氮热迁移的特性及相关影响因素。最后提出了"定量解析煤氮热迁移过程"这一国际学术难题的研究突破口。

| Abstract: | The heat transfer characteristics of nitrogen in coal determine the generation of NOx and its final emission amount in combustion process，which has great significance in controlling and governing the NOx pollution during combustion process． In this paper，the heat transfer process was divided into two different heat migration paths，volatile nitrogen and coke nitrogen． It was also summarized the heat transfer characteristics and related factors of volatile nitrogen and coke nitrogen in the combustion process． At the end，a breakthrough of the “quantitative analytical thermal migration process of nitrogen in coal”was achieved，which is an international academic puzzle． |
