Abstract:In SCR system, the velocity of flue gas field varies with the load, forming a gradient flow field. The characteristics of gradient flow field have important influence on the physical deactivation of catalyst. Through CFD simulation in this paper, it was found that the relative standard coefficients of flow field with characteristic flow velocity were 10.03%, 12.48% and 14.37% respectively. The uniformity of flow field deteriorated with the increase of flow velocity, and the alternating flow field was more like… Show more
