Research on Simulation of Urea-SCR Injection System for Marine Diesel Engine

Abstract:

The mixing degree of ammonia and exhaust gas has significant effect on the NO_x conversion efficiency of SCR (selective catalytic reduction) system. It is essential to investigate the structure of urea nozzle since it considerably impacts the atomization of urea water solution. This paper simulated the process of urea spray by the software FIRE and analyzed the influence of spray characteristics such as nozzle hole number, nozzle hole chamfering as well as the spray angle on the atomization of urea water solution. Simulation results can indicate the optimal nozzle for a certain circumstance which is beneficial to the engineering design.
