Abstract
To improve energy utilization of ship integrated energy system, while reducing energy consumption and pollution, the paper takes the thermodynamic system of the main engine as an example, establishes a model with the aid of thermal economic analysis method, and analyses the influence of scavenge air temperature and maximum firing pressure on the mechanical efficiency. And so the curves of mechanical efficiency changes with scavenge air temperature and maximum firing pressure and the optimal point are obtained. Results show that optimization can make the price of energy drop about 3.2%, while improving the system energy efficiency and economy. The method has a certain reference value for the design and management of the ship.
