Aalborg AV-6N

Aalborg AV-6N is a robust and highly efficient boiler with gilled water tubes which is designed to improve a plant’s overall efficiency by maximizing exhaust gas heat recovery. It is intended for steam and/or hot water production.

AV6N boilers 640x360

Aalborg AV-6N boiler is constucted to recover heat from diesel engines, gas engines or other sources.

The boiler’s compact and flexible design, which makes it easy to install, also allows cleaning during operation, which minimizes engine shutdowns and increases plant availability.

Natural circulation is used in the standard steam configuration with resulting advantages for reliability, safety and energy efficiency, although traditional forced-circulation models are available if specifically requested.

Designed with extended heating surface, AV-6N is compact and cost-effective. The possibility of cleaning during operation minimises the need for engine shutdowns and increases the overall plant availability.
