The Alfa Laval Aalborg XS-7V is a robust smoke-tube economizer. Easy to install, operate and maintain, it reduces the use of the fired marine boiler by recovering heat energy that otherwise would be lost through the exhaust gas. The Aalborg XS-7V is similar to the Aalborg XS-2V, but it shares a steam space with the fired boiler instead of having its own steam space. Its proven design includes a dual-inlet option, which creates high installation flexibility.
Easy steam production with dual-inlet flexibility
- Simple and reliable design based on smoke tubes
- Easy improvement of Carbon Intensity Indicator (CII)
- Short payback time (typically 1–2 years) through up to 25% fuel savings on the fired boiler
- Reduced wear and maintenance on the fired boiler
- Dual-inlet option allowing connection of two engines to one economizer
