초록 | The urea-selective catalytic reduction(SCR) system to reduce NOx emission needs the precise flowrate control to prevent ammonia slip, and the urea-water solution in the system is generally injected into the exhaust gas by the two-fluid nozzle with the adaptor that allows the carrier air supply. In this paper, the effects of carrier air supplying parameters on the variation of liquid flowrate in two-fluid nozzle were investigated by using the five times magnified nozzle adaptor model. The carrier air supplying positions and liquid-air supplying conditions were considered as the experimental parameters. The internal pressure of the adaptor and the flowrate issuing from the injection nozzle were measured at the liquid supplying pressure from 2 to 4 bar and carrier air supplying pressure from 1 to 3 bar. As the results from the experiment, the internal pressure of the adaptor and the flowrate issuing from the injection nozzle were varied with the carrier air supplying position and the differential pressure between the liquid-carrier air pressures. |
