Aalborg OL
The Alfa Laval Aalborg OL is a high-capacity, fired marine boiler for producing large amounts of steam or hot water. Available in two design pressures, it has a top-fired design that maximizes heat transfer and minimizes pressure loss. Ready for the fuel transition, the OL can use oils, biofuels and one alternative fuel of your choice. Additionally, it can be configured as an electric hybrid. These options can be implemented directly, or the boiler can be prepared for their installation later.
High-capacity fired boiler with multi-fuel and hybrid options
- Produce 12,500–45,000 kg/h of steam or hot water with high fuel efficiency
- Safely manage boil-off gas while producing 10,000–55,000 kg/h of steam
- Rely on trouble-free uptime, secured through robust design and user-friendly control
- Advance decarbonization by configuring for your choice of alternative fuels
- Take advantage of shore power or surplus electricity on board through hybrid operation
The Aalborg OL is a future-proof choice that lets you transition to LNG, methanol or ammonia – whenever the time is right for you. Hybrid and hybrid-ready options add to its flexible configuration, along with the choice of 9 or 18 bar(g) design pressure.
Like all Alfa Laval Aalborg marine boilers, the Aalborg OL draws on over 100 years of experience with boilers, burners and thermal applications on board. At the same time, it comes prepared for the future. This large-capacity boiler is ready for any marine fuel in current use or under discussion, including LNG and methanol.

Kako radi
Top-fired and available in two different design pressures, the Aalborg OL is a vertical, two-drum cylindrical boiler. Straight tubes connect the water and steam drums directly, which ensures safe circulation with no risk of overheating and subsequent tube burnout.
The furnace is built with membrane walls, which are constructed from gastight polygonal panels that make it resistant to gas pulsations. Containing only a minimum of refractory material, it is shaped to provide optimal combustion conditions. The convection section consists of straight pin tubes with bent pins, which provide a high coefficient of heat transfer and ensure low pressure loss. Circulation is promoted by downcomers placed outside the membrane walls.
Design data
Steam and hot water production
- Design pressure: 9 or 18 bar(g)
- Capacity: 12,500 – 55,000 kg/h*
- Burner recommendation: Alfa Laval Aalborg KBSD pressure-atomizing burner
*Gas valve train (GVT) required for boilers exceeding 45,000 kg/h capacity, necessitating a suitable indoor space for installation. Steam production capacity for boil-off gas (BOG) applications may vary depending on supply gas pressure to the system.

Aalborg marine boiler solutions for LNG as fuel
Alfa Laval Aalborg dual-fuel boilers are more than an efficient solution for your steam and hot water needs. Able to handle both free flow and methane mixed with inert gas, they provide safe, effective ways to manage boil-off gas (BOG) and simplify operations connected with tank inspection.
Aalborg marine boiler solutions for Methanol as fuel
Built on a century of thermal expertise, Alfa Laval Aalborg boilers are prepared to run on methanol, thanks to our future-proof MultiFlame burner concept. Adding to our already extensive combustion knowledge, we are now conducting large-scale methanol testing at the Alfa Laval Test & Training Centre.
Alfa Laval Test & Training Centre
Reliability is paramount in equipment for LNG use. Alfa Laval achieves it not only through years of experience but also through extensive testing at the Alfa Laval Test & Training Centre. This unique facility has an entire section dedicated to ensuring safe, efficient gas operations.
