- Integration with digital monitoring enhances operational performance
What Happened
Shipping companies and marine engineers are increasingly implementing smart heat recovery systems onboard vessels. These systems capture unused thermal energy generated by engines and convert it into usable power for onboard operations.
The development comes amid growing pressure from regulatory bodies to lower greenhouse gas emissions and improve energy utilization across fleets.
Key Details
Smart heat recovery in ships involves capturing excess heat from sources such as exhaust gases, engine cooling systems, and auxiliary machinery. This heat is then reused for power generation or heating purposes.
Core Components
- Exhaust gas economizers
- Heat exchangers
- Waste heat boilers
- Digital monitoring and control systems
Working Mechanism
- Heat generated by engines is captured through heat exchangers
- Thermal energy is transferred to secondary systems
- Recovered heat is used for electricity generation or onboard heating
Typical Applications
| Application Area | Function |
|---|---|
