EGR boiler from Alfa Laval is ready for testing
Exhaust Gas Recirculation (EGR) has firmly shown its ability to comply with Tier III NOx limits, which will enter into force in January 2016. Over 1000 hours of EGR operation have now been achieved aboard the Maersk Cardiff, a container newbuild from A.P. Moller-Maersk with a two-stroke MAN B&W 6S80ME-C9 engine. Developed by MAN Diesel & Turbo, the EGR process already relies on Alfa Laval's PureNOx, which provides the vital cleaning of the scrubber water. Now Alfa Laval is cooperating with MAN Diesel & Turbo to implement an EGR boiler, which could potentially add major energy benefits to the secure emission compliance. Having demonstrated reliable compliance with Tier III NOx legislation, as well as the potential for fuel savings in Tier II operation, the vessel's EGR installation will soon be expanded with another remarkable technology: a pressurized EGR boiler from Alfa Laval. "We have shown that EGR works smoothly and that it complies fully with the NOx limits appearing in 2016," says Michael Witt, Head of Retrofit Development R&D at MAN Diesel & Turbo. "Together with Alfa Laval and A.P. Moller-Maersk, we are now looking beyond compliance to optimize the system and to utilize opportunities for energy savings." The reasons ...
