摘要:
 选择性催化还原(SCR)系统的三维数值模型通常不单独考虑内、外扩散.本文建立描述电站SCR反应器内烟气流动、传热传质、复相催化反应的三维数值模型.在复相催化反应的模拟中,对内、外扩散及本征动力学分别进行了考虑.计算结果与试验数据吻合良好.建立的模型可用于电站SCR系统中,氨氮摩尔比大于1的状态下,组分浓度场、温度场、速度场的分析.研究为SCR系统三维数值模型的进一步完善提供了新的思路.
Abstract:
 A 3-D numerical model describing flue gas flow,heat and mass transfer,and heterogeneous catalytic reaction in a selective catalytic reduction(SCR) system of a power station was developed. Inter-phase transfer,intra-phase transfer and intrinsic reaction were respectively analyzed in the simulation of heterogeneous catalytic reaction.Good agreement between the experimental results and numerical prediction was obtained. The model can be used to investigate the distributions of species concentration,velocity and temperature in a power station SCR system when NH3 to NO molar ratio is greater than unity. The study sheds new light on further improvement of the numericalsimulation for SCR system.
