EFFICIENCY INCREASE IN SHIP'S PRIMAL ENERGY SYSTEM USING A MULTISTAGE COMPRESSION WITH INTERCOOLING

ABSTRACT
This paper focuses on an analysis of the potential increase of efficiency in ship's primal energy system using a turbocharger with multistage compression with intercooling, and diverting a greater flow of exhaust gases to power turbine of waste heat recovery system (WHR). Analysis of potential efficiency increase has been made for various stages of compression for a 100 % main engine load, and an analysis of five stage compression with intercooling for a main engine load between 50% and 100%.
