Waste heat recovery
Save up to 14% on energy use and carbon emissions with Alfa Laval boiler technology that recovers waste heat from your main and auxiliary engines.
From waste heat to added value
- Recover heat from both main and auxiliary engines
- Meet your steam needs in port and at sea
- Systems can boost propulsion
- Leverage overlooked heat sources, for example to superheat steam, to meet energy needs and emissions regulations
- Integration optimizes recovery and savings
Waste heat recovery solutions for any vessels
Our Aalborg waste heat recovery solutions can improve the energy efficiency of any vessel. Our extensive experience lets us design and install systems that maximize energy gains without any compromise in onboard safety.

Alfa Laval Test & Training Centre
At our Test & Training Centre, our marine equipment and applications are tested on the scale of an oceangoing ship – but with the control and convenience that cannot exist at sea. The full-size Gas Combustion Unit (GCU) accurately replicates marine environments, facilitating continuous solution innovation.

Further potential in auxiliary exhaust
Recovering heat energy from auxillary engine exhaust, for example, can do more than meet steam needs in port. For vessels whose long-stroke main engines produce cooler exhaust, it can also provide a needed boost in steam production an route.
Not limited to serving onboard equipment, today's wate heat recovery systems can even be constructed to provide a boost in propulsion.
