The Alfa Laval Aalborg i-OC is a high-performance composite boiler, capable of generating

steam through the firing of oil and/or the recovery of waste heat from engine exhaust gas.

Its modular design comprises one oil-fired section and one–three exhaust gas sections.

One of the exhaust gas sections is connected to the main engine, while the two other

exhaust gas sections are optional and can be connected to one or two auxiliary engines.

Application

Able to work with multiple heat sources, the Aalborg i-OC offers reliable production of steam

while sailing and during port stays. As a composite boiler, it demands considerably less space

than having both oil-fired and exhaust gas boilers on board. In addition, it has a smaller

footprint and weighs less than older composite boiler designs. At its operating pressure of 

7 bar(g), the Aalborg i-OC can produce up to 2500 kg/h of steam with its oilfired section

and up to 1000 kg/h with its exhaust gas sections.
