TASK 1.

Characterisation of different technical and operational systems to meet the SOx and NOx emission limits

2. Detailed description of influence of different exhaust gas treatment systems regarding the heat recovery potential

3. Appointment of exhaust gas heat recovery potential in an example

4. Evaluation of results

1. Different EGTS Installment = Different WHRS Potential
2. Scrubber Influence WHRS
3. WHRS + EGTS = Improvable

Hypothesis

 EGTS does not affect WHRS

SLIDE 10

38oC to be used on WHRS systems since 300 degree is needed for NOx Scrubber 40oC to be used on WHRS systems 250oCelsius or more difference because the EGTS Coolant temperature which is too high Recommended 94,71oC to be used on WHRS systems The number of requirement for SOx Scrubber is same with Class’ Rules. With the chance to improve it. Will be discussed next.

SLIDE 11

Using Better Heat Resistance Material

SLIDE 12

Shorter Pipe to Reduce Heat Loss

SLIDE 13

Putting Consideration into Chemical Products

SLIDE 14

No Regulation for Minimum Temperature.. Acid Rain -> Non-Acid Material Reducing 180 degree to 70 degree We can boost up WHRS from 11% to 18.26% If this possible than EGTS installation will boost up WHRS possibility

Using the Acid-Free Material on Scrubber Piping System
