Working principle

The Aalborg XS-2V and XS-7V are installed after a vessel’s

main or auxiliary engines. When the exhaust gas passes over

the economizer’s heating surface, the waste heat energy in

the gas is absorbed for the production of steam. Dry running

is possible in the event of an emergency.

The two models differ in how produced steam is handled:

• The Aalborg XS-2V is a full exhaust gas boiler with its own

steam space, which can operate independently from the

fired boiler.

• The Aalborg XS-7V is designed for forced circulation

and is used in connection with one or more fired boilers,

which act as the steam space.
