Abstract:In order to solve the problems of large workload,long cycle,and high trial and error cost in traditional testing method of low pressure selective catalytic reduction(SCR)reaction equipment for ships,a method combing CFD simulation and experimental verification was adopted.Obtaining the optimal design plan before prototype testing,which means meeting the requirements for denitrification efficiency while optimizing the total pressure drop of the system,can greatly improve the efficiency and accuracy of the design,reduce the number of tests,and shorten the research and development cycle.This method plays an important guiding role in the design of SCR reaction equipment products. |
