| 제목 | CFD Simulation of the Hybridization of Urea-SNCR with SCR in a Pilot-Scale Flow Reactor |
| 초록 | In recent years there has been a considerable growth and development in flue gas control technologies capable of reducing NOx emissions to the low levels required by current legislation. The hybrid SNCR-SCR technology is expected to provide a cost effective method of NOx reduction while balancing capital and operating costs. In this study, the hybridization of urea-based SNCR with SCR in a pilot-scale flow reactor is investigated through the experimentation and computational fluid dynamics (CFD) simulation. The pilot system is installed with a 150kW LPG burner. The V2O5-WO3/TiO2 monolith honeycomb is used as a catalyst in the SCR zone. A reduced SNCR chemistry using urea-water solution is implemented into a turbulent reacting flow CFD model. The model is combined with the discrete phase model to account for the interaction between flue gas and the droplets of urea solution. An Arrhenius-type reduced model is used for the surface chemistry of SCR process. The simulation resultsshow a good agreementwith the experimental data of NO reduction and NH3 slip obtained from the hybrid SNCR-SCR process in the pilot-scale flow reactor. |
