Waste Heat Recovery
While heat recovery systems successfully capture a portion of the waste heat in exhaust gases, additional opportunity remains in the exhaust gases exiting recovery units. Exhaust gases exiting waste heat recovery systems have temperatures ranging anywhere from 250°F [121°C] to 1,800°F [982°C].

Waste heat recovery on ships
The objective of this heat exchanger is to recover low-medium waste heat from the exhaust gases to a boiler feed water (BFW) to reduce the energy required to achieve the boiling temperature. The heat is reused in the same process to pre-heat the water/steam sent to the steam turbine or to preheat the fuel inlet.

The heat flux rates over the entire tube length of the WHB should be evaluated, especially the turbulent en-trance area near the end of the ferrules. The heat flux should not exceed 50% of maximum nucleate-boiling flux at design, and 65% for maximum service conditions. These limits will keep the tube wall within 18°F of the water boiling ...

What are Waste Heat Recovery Boilers?
Waste heat recovery boilers operate on the same principle as a typical boiler but take the energy from exhaust gases rather than their burner. The hot exhaust gases come from a process furnace and enter a large chamber. The gases then move over pipes containing cold water, and heat travels to the lower temperature water and …
