SCR脱硝反应器内流场均匀性分析及优化设计

Study on SCR Denitration Reactors' Flow Field Uniformity and Its Optimal Design

文章对某600MW机组拟定的烟道及SCR脱硝反应器内的流场进行数值模拟及分析,针对流场分布不均匀的问题提出了三种导流板位置布置方案,使得出口速度达到均匀。对不同导流板布置方案的模拟及分析表明:导流板可以明显改善SCR反应器内流场均匀性,采用在三个部位添加导流板的方式,是使SCR脱硝反应器内流场均匀的最佳方案。

Based on a numerical simulation analysis of the flue pipe and SCR denitration reactor＇s flow field of a certain 600MW power set, this article, proposes three schemes guide plates serve to improve SCR denitration reactors＇ flow field guide plates in three places serves as the optimal way to maintain the for guide plate layout, which indicates that uniformity significantly and that installing uniformity.
