Design

The Aalborg XWi has the same heat transfer features as a

traditional exhaust gas boiler with forced circulation, but its

special design eliminates safety risks, heat losses, continuous

maintenance needs and pump operating costs.

The heating surface of the Aalborg XWi is made up of gilled

water tubes as standard, with a construction that minimizes soot

build-up. In addition, the system can be equipped with optimized

steam sootblowers. Design pressure and boiler capacity can be

optimized according to specific needs.

The boiler can be designed with its own integrated steam

drum, or with a separate steam drum. There are no operational

connections to fired boilers, which means more redundancy, but

still considerably less piping. The boiler’s own dedicated water

circulation system eliminates the risk of water hammering.
