Air pollution is the main cause of global warming effect that is a main issue nowaday in the modern era. Today almost all goods are transported via sea by using ships worldwide. Diesel engine is used mostly as their prime mover. Among all types of vehicles in the world, ship is the the biggest producer of air pollution based on the quantity of fuel consumption. According to MARPOL 73/78 Annex VI, air pollution must be prevented either by utilizing exhaust gas from the engine
Thermodynamically and mechanically, the maximum efficiency of diesel engine is around 60%. While the rest 40% remains as wasted heat, and approximately 25-30% of it is in the form of exhaust gas. There are possibilities to reuse this heat for certain system on the ship.
In this study, storage calorifier is studied as the part of wasted heat recovery system. The aim of this study is to design storage calorifier on board PKR (perusak kawal rudal) ship, and to conduct technical studies on the designed domestic system. The methodology that is used is thermodynamic calculation based design and software based design using HTRI Software. The results will be compared to determine the performance of the system and then used to acquire the economic analysis from saving fuel oil of auxiliary engine. One of the final results is comparison between software based and calculation based design, with the obtained over design is 6.13 %. Heat Exchanger Research Inc. (HTRI) 6.0 the results obtained are not too much difference. From calculation based design, the obtained area is 640.076 ft2 while the obtained area of software based design is 494,406 ft2 . For Overall Coeeficient from manual calculation be obtained 6.5 btu/ft2.h.F and from HTRI software is 6.96 btu/ft2.h.F. For over design from calculation manual and htri software is 6.13 %. The economic analysis results that is after using the storage calorifier, fuel consumption of auxilary engine at 50%MCR can save 139659 liter/years.
