Aalborg OC-TCi
The Aalborg OC-TCi is a marine composite boiler that produces steam through fuel combustion and/or exhaust gas waste heat recovery. With its high efficiency and its ability to utilize existing thermal energy, it can reduce environmental impact while providing reliable heating for marine operations. Thanks to its “ready boiler” concept, it is also prepared for today’s and tomorrow’s emission-reducing fuels, including LNG, biofuels and methanol.
Self-cleaning marine composite boiler with multi-fuel capabilities
- High fuel efficiency and exhaust gas waste heat recovery (up to three sources) that positively influence carbon footprint
- Easy upgrading to operate on new fuels as vessels decarbonize
- Easy installation and maintenance due to modular construction – fewer components and less weight
- Easy operation thanks to straightforward and user-friendly design
- Steam capacity: oil-fired side 1200–6500 kg/h, exhaust gas side 300–5000 kg/hr
The Aalborg OC-TCi is a marine composite boiler with decarbonization and the fuel transition in mind. Besides operating on today’s fuels, including low-sulphur fuels, biofuels and LNG, our marine boiler is designed for compatibility with methanol and the other emission-reducing fuels that will appear over time. Alfa Laval’s “ready boiler” concept provides a future-proof platform, allowing the existing burner and boiler pressure section to be adjusted as needed.
Because the Aalborg OC-TCi can also produce steam through exhaust gas waste heat recovery, it significantly reduces carbon footprint. Fuel is saved through the boiler’s exceptional thermal efficiency, which is ensured in part by self-cleaning TCi (Turbo Clean, intelligent) technology. But the Aalborg OC-TCi can utilize exhaust gas waste heat that already exists on board, which means even less fuel is burned. Since up to three engines can be connected to the same Aalborg OC-TCi unit, the solution saves space compared to standalone economizers.

Application
Typically used to generate steam for HVAC and engine room consumers, the Aalborg OC-TCi boiler can also function as a steam drum for one or more exhaust gas boilers. Additionally, it is approved for boil-off gas (BOG) management on vessels that use LNG as fuel.
Design for our marine boiler
The Aalborg OC-TCi boiler is delivered with a preassembled Aalborg burner built on Alfa Laval's innovative MultiFlame (MF) concept: MF PA or MF SAS. Both boiler and burner are engineered and produced in-house to ensure the highest reliability. The compact design is standardized but customizable, which means easy, time-saving installation.
Aalborg OC-TCi boiler
A fired section with helix tubes provides a large heat transfer area with high efficiency. For waste heat recovery, the boiler has 1–3 exhaust gas sections with smoke tubes, allowing it to utilize exhaust gas heat from up to three engines.
Aalborg MF PA burner
The Aalborg MF PA is a side-fired, pressure-atomizing burner that supports conventional fuels and gas fuels like LNG.

Aalborg 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.
Marine equipment and 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
As the marine industry decarbonizes, reliability is paramount in any fuel-related equipment. Alfa Laval ensures reliability with new fuels by combining long experience and deep fuel insights with extensive testing at the Alfa Laval Test & Training Centre. The facility’s unique 2800 m2 testing space plays a key role in many fuel research projects.
