Compact marine boiler economizer for auxiliary engines
When operating marine vessels, significant energy is wasted as heat from auxiliary engines. Reclaiming this heat can greatly enhance fuel efficiency and lower your vessel’s CO2 emissions.
Recovers waste heat for steam production
The Alfa Laval Aalborg Micro is a compact marine boiler economizer that capitalizes on waste heat from auxiliary or smaller main engines. It is designed to work with an existing oil-fired boiler to improve fuel efficiency and reduce emissions. By using an external steam space, this lightweight economizer is versatile and easy to install. On DFDS ferries, it has demonstrated remarkable fuel savings and a reduction in CO2 emissions by around 900 tonnes annually. It supports capacities from 500 kW to 5 MW and significantly reduces wear and maintenance on the oil-fired boiler. The Aalborg Micro’s compact design allows for easy retrofit, often achieving a payback time of 1-2 years. The system also features an internal damper for dynamic management of pressure drop.
