Alfa Laval - Aalborg OC-TCi

Aalborg OC-TCi

The Alfa Laval Aalborg OC-TCi is a space-saving marine boiler for vessels requiring small to medium amounts of steam or hot water. As a composite solution, it has both a fired section and an exhaust gas section, allowing it to be heated through combustion and/or waste heat recovery.

Space-saving composite boiler

  • Capacity in steam and hot water production: 750–8000 kg/h (fired section), 180–5000 kg/h (exhaust gas section)
  • Capacity in dual-fuel and boil-off gas application: 750–6500 kg/h (fired section), 180–5000 kg/h (exhaust gas section)
  • Future-proof operation on all marine fuels
  • Superior combustion and thermal efficiency
  • Digital services available to enhance performance and lower OPEX

Like all Alfa Laval Aalborg boilers, the Aalborg OC-TCi 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 composite boiler – heated through combustion and/or waste heat recovery – is ready for any marine fuel in current use or under discussion, including LNG and methanol.

Developed in-house, Alfa Laval Aalborg boiler solutions are tested and optimized at the Alfa Laval Test & Training Centre and thoroughly proven at sea. Our experts ensure high thermal efficiency and the correct steam balance for your vessel, as well as global access to boiler services. Choosing boiler connectivity lets you access our knowledge continuously, using it to safeguard uptime, enhance performance and lower your operating costs.

How it works

Preassembled and installed vertically, the Aalborg OC-TCi consists of a fired module with helix tubes and an exhaust gas module with smoke tubes. In the Aalborg OC-TCi Multiple Inlet version, the latter module is suitable for use with one main engine and two auxiliary engines. The boiler provides effective self-cleaning, thanks to its built-in TCi (Turbo Clean, intelligent) technology and its relatively high exhaust gas velocity compared to other composite boilers. It can also be fitted with a compact silencer to suit any type of diesel engine.

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.
