Aalborg OS

Aalborg OS is a standard preassembled boiler. High performance is ensured by the use of the optimally designed pin-tube elements.


The Aalborg OS (formerly MISSION™ OS) is supplied as a standard, preassembled boiler unit. Aalborg SO is a vertical cylindrical boiler made of mild steel has an integrated control panel.

High performance is ensured by the use of the optimally designed pin-tube elements.

These elements are also used for support of the top plates of the furnace and boiler. The inclined mounting of the burner provides good combustion with all grades.

Πως δουλεύει

We recommend the use of Alfa Laval Aalborg oil-fired burners for our Aalborg OS boilers as they are designed and optimised together, the burner forming an integrated part of the boiler.

Alfa Laval Aalborg rotary cup burner-
Aalborg KBE

The Aalborg KBE rotary cup burner is an optimized, standardized design of Alfa Laval's well-proven Aalborg KB burner. With the electronic air/fuel ratio control, an extremely precise combustion control is achieved. The Aalborg KBE burner is compact and low weight, and the control system user-friendly and safe.

  • Capacity range: 0.3 – 0.97 MWe
                              150–1,300 kg/h

Alfa Laval Aalborg pressure atomizing burner-
Aalborg KBOG-E

Based on the proven Aalborg KBO-E modulating pressurejet burner, the Aalborg KBOG-E is a reliable dual-fuel burner that meets the growing demand for fuel flexibility onboard the world’s fleet. When used with small capacity Aalborg OS and OC boilers, it is suitable for firing liquefied natural gas (LNG) as an alternative to heavy fuel oil (HFO) and marine gas oil (MGO) onboard LNG carriers as well as other commercial vessels, such as tankers, bulk carriers and container ships carrying LNG bunker tanks.

The Aalborg KBOG-E dual fuel burner is designed to fit small
Aalborg OS and Aalborg OC boilers ranging in steam capacity
from 1.6 - 6.5 t/h and 0.75 - 5.0 t/h, respectively.
