| 摘 要： | 本文以GRI 3.0数据库为基础,结合CHEMKIN模块软件中敏感性分析的方法对煤粉再燃燃烧过程进行了数值模拟研究.通过对整个全模型反应方程进行分析,可以把整个反应机理模型主要分为碳氢组分转化反应机理和含氮组分转化反应机理两大类.本文重点对含氮组分转化反应机理进行了分析.在模拟的基础上,对含氮组分HCN、HNCO、NHt、NCO等转化反应进行了分类,系统地讨论了燃烧过程中含氮组分转化反应对NO的敏感性分析,清晰地揭示了含氮组分生成与还原NO的途径以及作用大小,为实际超细煤粉再燃燃烧技术提供了一定的理论依据.

| Abstract: | In this paper,on the basis of GRI3.0 data base,numerical simulation of coal reburning combustion processes using sensitive analysis method of CHEMKIN were discussed.Analyzing from the whole reaction mechanism model,the model could be divided into two parts:hydrocarbon trans- forming mechanism and nitrogen components transforming mechanism.And the latter was chosen to be analyzed here.The transforming reactions on nitrogen components(HCN,HNCO,NH_i and NCO et al)were classified,the sensitive analysis on nitro... |
