CFD APPLICATIONS ON SELECTIVE CATALYTIC NO_x REDUCTION (SCR) SYSTEMS

摘要

For the last several years, CFD modeling has been successfully used in Southern Company as one of the design and analysis tools to provide engineering insight to retrofitting Selective Catalytic NO_x Reduction (SCR) systems to coal-fired steam power generation plants. SCR technology is the most effective method for reducing NO_x emissions by at least 75% ～ 90%. This paper will summarize a few selected CFD applications that were proved to be essential in the SCR design and optimization processes. For validation purposes, some of the CFD results, such as pressure drop, were compared with the available measurement data from the scaled physical flow models. They generally agreed well.
