SIMPLIFIED METHOD  OF WATER COOLED EXHAUST SYSTEM  DESIGN AND PERFORMANCE ASSESSMENT

 

The  water  cooled  exhaust  systems  are  not  often  used  onboard  ships.  Prime  goal  is  to  lower temperature  of  exhaust  gas  from  main  propulsion  and  auxiliary  engines  to  the  defined  limit.  The design of such systems require detailed analysis of propulsion system operational parameters  to meet designer  expectations.  The  paper  outlines  the  cooled  exhaust  system  design  problems  in  specific application.  The simplified method of evaluation of  expected cooling water flow requirements has been  developed.  Based  on  marine  diesel  engines  test  bench  data,  the  results  of  short  analysis  of cooling  water  demand    for  two  different    diesel  engines    are  presented.      A  simplified  engineering approach  may  be  useful  for  assessment  of  exhaust  gas  cooling  system  performance  in  commercial application like rescue vessels wet exhaust design or  exhaust gas cleaning systems.
