| Abstract: | The performance of urea-nozzle directly affects the work efficiency of SCR system.According to the requirements of the engineering discipline of main engine plants,anti-crystallization performance of two types nozzles were analyzed on engine test bench.The test results showed that under the condition of 500~800 kg/h engine exhaust flow,550℃exhaust temperature,100 ml/h urea injection flow rate,anti-crystallization performance of all nozzles meet the requirements.Meanwhile the performance comparison provides the basis for nozzle structure optimization and performance improvement. |
