Constructed with smoke tubes, the Aalborg XS-TC7A is a compact and efficient exhaust gas economizer for installation after the auxiliary engines. When used in combination with a waste heat recovery system installed after the main engine, it significantly reduces the oil consumption of the oil-fi red boiler under most load conditions.
Since the operation of the auxiliary engines is not continuous, the economizer has been developed for varying loads. It features a specialized convection section, optimized to augment heat transfer through increased turbulence at the exhaust gas boundary layer. This allows increased steam production while reducing the economizer’s weight in comparison to other waste heat recovery systems.
Alfa Laval is today a world leader within the key technology areas of heat transfer, separation and fluid handling. Our company was founded on a single brilliant invention and innovation remains at the heart of everything we do.
