摘　　要：介绍了我国烟气脱硝技术的现状,重点分析了SCR烟气脱硝技术的特点,指出流场优化是SCR烟气脱硝技术的一个关键因素,而数值模拟方法是实现低耗资、快速、全面预测流场数据的途径。在评述本领域数值模拟方法的应用历程和现状的基础上,分析了对SCR烟气脱硝系统的非均相化学反应考虑不全面,以及缺乏足够的模型试验结果验证模拟结果等问题,解决这些问题是今后发展的方向。The present situation of flue gas denitration technology in China is introduced, focusing on the a- nalysis of the characteristics of the SCR flue gas denitration technology. It is pointed out that the flow field optimization is a key factor of SCR flue gas denitration technology,numerical simulation is fit for the realization of low cost, fast and comprehensive prediction of the flow field data. On the basis of reviewing of application history and status of the numerical simulation method in the field, analysis is made of the problems in the uncomprehensive consideration of SCR system heterogeneous chemical reaction and the lack of enough model test results to verify the simulation results. The future development will be oriented to find out the solutions to these problems.
