Abstract:Based on the technical characteristics of marine low speed marine diesel engines, a type of low pressure SCR system was designed and bench test was carried out. The test results show that this SCR system boasts obvious NOx reduction, very little NH3 escape, and could meet with relative emission regulations. Besides, with the SCR system, the exhaust gas pressure drop value can meet the design requirement, and it has very little influence on the fuel oil consumption. |
