Abstract:

The numerical model of SCR denitrification system is established. Simulate the SCR system where installs mixer by the way of installing rectifier grille and three types of guide plates to analyze the changes of velocity, pressure and ammonia concentration before catalyst layer. The results indicate that setting rectifier grille and changing the guide plate size can make velocity and pressure of the whole flow are more stable. In plan 4, the deviation of ammonia concentration at the catalyst inlet section is 3.58%, avoid the phenomenon of ammonia escape and its satisfies the design requirements of SCR denitration system Keywords: SCR denitrification system; rectifier grille; guide plates; pressure drop
