Cruise waste heat recovery
Effective waste heat recovery significantly improves the fuel efficiency of a cruise ship’s heating system. Waste heat is recovered directly from the engine exhaust gas and converted into steam, rather than being lost to the atmosphere. Alfa Laval’s natural circulation waste heat recovery boilers use a full-system delivery approach tailored to your needs.
