Study of the functional parameters of the freshwater generation system, as an integral part of the waste heat recovery system for a tanker ship

Abstract

A ship needs fuel for both travel and on-board operations. In the most general case, the fuel is converted on board the ship into energy in the form required for its end use: mechanical power for propulsion, electrical power for auxiliary board systems and thermal power for thermal needs. In this paper, I propose to deal with both elements of theoretical calculation and real elements of the operation of the freshwater generation system from the main engine of the ship. I chose to treat this system because it is the main subassembly of the residual heat recovery system from the main engine through cooling water. In the theoretical calculation, The results of the paper will be focus on calculation of the geometric and functional parameters of the fresh water generator. In the final part of the chapter, I will refer to the real parameters of the freshwater generation system where I will draw operation diagrams to highlight as concretely as possible the operation of this system on board the ship.
