Description
The forced circulation economizer is designed for recovering heat from the exhaust gas of diesel engines.
The Aalborg XC (formerly MISSION™ XC) consists of an effective, compact convection section built up as concentric bare tube coils connected to the inlet and outlet headers with integrated inlet and outlet boxes. The robust construction is designed to withstand gas pulsations. Cleaning of tubes is accomplished by sootblowing during service or, for use in ports, water washing either through the inspection door in the uptake or by means of an integrated water washing device.
In connection with a thorough revision/standardization of Alfa Laval's marine boiler product range, the exhaust gas economizer previously referred to as AV-9 has been renamed to Aalborg XC. The abbreviation refers to eXhaust gas Coil tube boiler.
Additional equipment
For control of the steam capacity the Aalborg XC economizer can be fitted with an internal by-pass system.
For compact and easy installation the Aalborg XC can be provided with integrated silencer.
