Compact marine boiler economizer for auxiliary engines
Efficiently reclaim waste heat from auxiliary engine exhaust to boost steam production, reduce fuel consumption, and meet stringent environmental standards, making it a critical component for enhancing marine vessel energy efficiency.
Recovers Waste Heat for Marine Steam Production
The Aalborg Micro from Alfa Laval is a compact marine economizer engineered for efficient waste heat recovery in maritime applications. Integrated after auxiliary engines, it utilizes a forced convection mechanism to absorb exhaust heat and convert it into steam, optimizing marine steam systems while minimizing emissions. Suitable for marine power generation and ship propulsion, it addresses energy reclamation and exhaust gas cooling challenges. With a capacity of up to 5 MW and adaptable installation, it offers significant fuel savings and environmental benefits. Its lightweight design facilitates easy retrofitting on vessels, and the internal damper system allows dynamic pressure management. The Aalborg Micro significantly lowers CO2 emissions, making it an eco-friendly solution for shipping companies, ferry operators, and maritime transport businesses seeking to enhance energy efficiency and sustainability.
