Using CFD for SCR Design
For the last several years, Computational Fluid Dynamics (CFD) modeling has been successfully used in Southern Company as one of the design and analysis tools to retrofit Selective Catalytic NOx Reduction (SCR) systems to existing coal-fired steam power plants. SCR technology is the most effective method to reduce NOx emissions by at least 75% ~ 90%. CFD has been integrated in many aspects of design and engineering processes and has provided values and benefits unattainable by either physical flow models or field tests. This paper will summarize two selected CFD applications that were proved to be essential in the SCR optimization processes.
