Description
The Aalborg XW (formerly MISSION™ XW) is a water tube, forced circulation exhaust gas boiler/economizer. It is specially designed for heat recovery from diesel engine exhaust gas but the basic design suits numerous applications.
The heating surface is made of double gilled tubes with a spacing which minimizes soot build-up. It is supplied with an efficient cleaning system with steam or compressed air sootblowers.
A design with single gilled tubes is also available.
The economizer can be supplied with a dividing wall system for connection of several exhaust gas sources to one boiler.
The Aalborg XW may be used in conjunction with an oil-fired auxiliary boiler or a separate steam drum, in both cases acting as a steam/water separator.
In connection with a thorough revision/ standardization of Aalborg Industries' marine boiler product range, the exhaust gas economizer previously referred to as AV-6N has been renamed to Aalborg XW. The abbreviation refers to eXhaust gas Water tube boiler.
