Aalborg XS-7V

The Aalborg XS-7V economizer is designed for utilisation of exhaust gas from the diesel engines for production of steam. The design is tailormade according to exhaust gas demand and temperature.

Exhaust gas economizer

The economizer is carried out with the smoke tubes welded to the tube plates at both ends, and this robust design can, in emergency cases, withstand running dry.

The Aalborg XS-7V is designed without steam space and is built with the tubes welded to the tube plates at both ends and they can, in emergency cases, withstand running dry.

The sizes of the economizers depend on required steam capacity, amount of exhaust gas, temperature, and working pressure.
