Aalborg XW
The Alfa Laval Aalborg XW is an exhaust gas economizer with gilled water tubes and forced circulation. Intended for waste heat recovery after diesel engines, it has a proven design that withstands vibrations and exhaust gas pulsation. It can be used in combination with a fired auxiliary boiler or a separate steam drum, which acts as a steam/water separator. The unit has a steam capacity of 0.2–17.0 tonnes and is available in two design pressures: 18 or 24 bar(g).
Exhaust gas economizer with forced circulation
- Reduce fuel consumption and emissions by recovering heat from engine exhaust gas
- Get the required capacity from a compact unit, thanks to an optimized tube design
- Connect one unit to multiple exhaust gas sources with an optional dividing wall system
The Aalborg XW is specially designed for waste heat recovery after diesel engines. However, its basic design is suited to numerous applications.
Reasons to choose the Aalborg XW
The Aalborg XW economizer has a reliable design that ensures stable operation and high steam output from the available waste heat.
Robust constructionThe Aalborg XW withstands vibrations and exhaust gas pulsation when recovering heat after large marine engines. |
Optimized tube designThe double-gilled tubes of the Aalborg XW, which create a large heat transfer surface, are spaced in a way that minimizes soot build-up.
|
Effective cleaning systemThe proven cleaning system of the Aalborg XW uses either steam or compressed air sootblowers to maintain thermal efficiency. |
Optional dividing wallsThe Aalborg XW can be supplied with a dividing wall system, which allows one economizer to handle several exhaust gas sources. |
Add-on heatingA superheater and preheater can be added to the basic Aalborg XW design. |
