摘　　要：应用快速反应模型和ＳＩＭＰＬＥＣ算法对发生在１ 个简化煤粉炉炉膛还原区段中的天然气再燃烧还原烟气中的ＮＯｘ 反应过程进行了二维数值模拟，得到温度场和ＮＯ 的浓度场，并对模拟结果进行了简要的分析。Deoxidizing NO x contained in the flue gas by reburning it with natural gas is a practical way to reduce the emission of NO x. Using the fast reaction model, employing the SIMPLEC arithmetic, a 2 D numerical simulation of the above chemical reactions which happened in a PC boiler utility is achieved in this paper. The temperature field in the reactor and the concentration field of NO are obtained and a simple analysis of the computing results is given in the end. Figs 4, table 1 and refs 5.
