Heat Recovery Heat Exchangers for Energy Recovery of Exhaust Gases from Ship Engines

Heat recovery heat exchangers capture heat from the exhaust gases emitted by marine engines and transfer this heat to other fluids such as seawater or hot water for heating or power generation.

By recovering heat from the exhaust gases, fuel consumption can be reduced, thereby improving the overall energy efficiency and economy of the engine.

By recovering and utilising the heat from the exhaust gases, the emission temperature can be lowered, thus reducing the emission of harmful gases and meeting environmental requirements.

Applications

Power Generation: Recovered heat is used in steam generators to drive turbine generators to provide the ship's electrical needs.

Preheating fuel: Use the heat of exhaust gases to preheat heavy oil or other fuels to improve fuel flow and combustion efficiency.

Provide hot water: Provide hot water for the crew to meet domestic needs.

Design Considerations

Material selection: Corrosion and high temperature resistant materials need to be selected to suit the marine environment and exhaust gas characteristics.

Heat exchange efficiency: The design should maximise heat exchange area and fluid flow to improve heat recovery efficiency.

Maintenance and Cleaning: The design should be easy to access and clean to prevent dirt accumulation from affecting performance.
