采用数值模拟方法对火电厂SCR系统的预报具有经济、快捷和实用的优点。本文在总结国内外大量文献资料的基础上,对数值模拟技术在烟气SCR脱硝中的应用进行了综述。并把SCR模拟的发展归纳为:非均相动力学模型;均相反应速率模型;催化剂单孔道反应数值模拟;系统流场的数值模拟。在此基础上,提出了三维流动和详细反应的耦合是今后SCR模拟的一个重要发展方向。

Abstract:

Numerical simulation for selective catalytic reductionSCRsystem of power plant is of economicefficient and practical advantages. Based on literature investigationthe application of numerical simulation technology in flue gas denitration is reviewed. The development of mathematical models for SCR reaction is summarizedincluding kinetics and rate order based models. The numerical simulation for SCR system and catalyst channels is discussed. The coupling of three-dimensional turbulent flow and SCR reaction is proposed as an important development direction for SCR simulation.
