Description
The Aalborg XS (formerly MISSION™ XS) economizer is designed for recovering heat from the exhaust gas of diesel engines for production of steam. The design is tailormade according to exhaust gas demand and temperature. The boiler has a high gas velocity so as to minimize fouling.
The economizer is carried out with the smoke tubes welded to the tube plates at both ends, and this robust design can, in emergency cases, withstand running dry. Type The Aalborg XS 2V comes with its own steam space and is able to operate independently from the oil-fired boiler/steam drum.
The Aalborg XS-7V is designed for forced circulation and operation together with an oil-fired boiler.
For compact and easy installation The Aalborg XS can be equipped with integrated silencer.
The sizes of the economizers depend on required steam capacity, amount of exhaust gas, temperature, and working pressure.
In connection with a thorough revision/ standardization of Alfa Laval Aalborg marine boiler product range, the exhaust gas economizers previously referred to as AQ-2 and AQ-7 have been renamed to Aalborg XS-2V (with steam space) and Aalborg XS-7V (without steam space). The abbreviation refers to eXhaust gas Smoke tube boiler, Vertical model. |
