| Abstract:To comply with the Tier Ⅲ NOx legislations，based on the main engine of a 210 000 DWT bulk-cargo ship, the two NOx reduction technologies which are EGR and SCR are compared and studied. The technical characteristics, cost difference are analyzed, and based on the characteristics and system layout of this ship, it is believed that SCR has more advantages. The research offers reference for the seletion of NOx reduction technologies. |
