Abstract

In the present paper, the waste heat recovery (WHR) installations used for the production of saturated steam and electric power for the cases of a two-stroke and a four-stroke engine ship propulsion plant are investigated. The examined waste heat recovery system is considered to be of the single steam pressure type with an external heat exchanger for the heating of feed water entering into the boiler drum. The option of using the engine air cooler for heating the feed water was also examined. The waste heat recovery installation was modeled under steady state conditions and the derived WHR installation parameters for various engine loads are presented an analyzed. Furthermore, using the simulation results, the improvement of energy efficiency design index (EEDI) of a typical merchant ship is calculated and the impact of the WHR on the ship EEDI is discussed.
