MAN Energy Solutions has launched its Exhaust Gas Recirculation (EGR) electrical turbo blower ETB40 for which its already secured its first order.

CMD has already placed its first order for the new blower, which makes up an important component of several MAN B&W two-stroke 7G60ME-C9.5 main engines ordered for newbuild vessels.

“Our development of the ETB series is a strategic decision and a significant addition to our existing, proven EGR technology that will play an important role in maintaining IMO Tier III emission standards,” said Ralph Klaunig, Vice President and Head of Turbocharger and Exhaust Gas Systems Sales, MAN Energy Solutions.

“This will enable customers to achieve sustainable value creation in the transition towards a carbon-neutral future.”

Industry first

Individual ETB40 units will be installed aboard each vessel as part of the main-engines’ integrated EGR system.

The order represents the first time that CMD has employed EGR technology for compliance with IMO Tier III regulations, having previously commissioned several successful Selective Catalytic Reduction applications.

The blower is a core component of MAN Energy Solutions’ high-pressure EGR system that raises the exhaust-gas pressure in order to overcome the pressure difference exhaust gas and scavenging air receiver. In addition, the blower actively controls the recirculated exhaust gas flow during the EGR flow by varying the blower speed.

This helps ensure IMO Tier III compliance in emission-controlled areas (ECAs) and potentially also in IMO TIER II mode with the new Eco EGR feature (officially acknowledged by DNV GL).

Since May 2015, two ETB18 prototypes have run successfully on an 82,000-dwt bulk carrier equipped with a MAN B&W 6S60ME-C 8.2 Tier III engine.

The ETB40 passed its Factory Acceptance Test on 17 October 2018.
