NOx Reduction by Combination of Charge Air Moisturizer and Exhaust Gas Recirculation on Medium Speed Diesel Engines
NOx emission from diesel engines is a principal toxic ingredient of environmental pollutants. Thus NOx from diesel engines has been limited by the global and local regulations which have been becoming more stringent in connection with the recent environmental problems. IMO(International Maritime Organization) Tier III regulation which requires to reduce NOx by 75% from the current Tier II regulation(20% reduction from Tier I regulation) will be effective in 2016. Several methods such as combustion optimization, EGR (Exhaust Gas Recirculation), water addition and high pressure turbo charger etc. have been developed to reduce NOx. Each method is not enough to abate NOx to comply with the IMO Tier III regulation, but combination of the NOx reduction methods is able to satisfy the regulation. Hyundai Heavy Industries Co., Ltd.(HHI) has developed charge air moisturizer( ChAM) which humidifies charge air with water vapor and has also tested EGR system for NOx reduction. HHI has enhanced NOx reduction efficiency by combination of the EGR and the ChAM systems on a medium speed diesel engine, and has confirmed that NOx emission was kept under the IMO Tier III regulation. The combination of the EGR and the ChAM system can be a candidate as the main NOx reduction technology to comply with the IMO Tier III regulation.
