Total Energy Applications for Ships Service Power

With the advent of high-speed, gas-turbine-powered naval vessels, new lighter weight concepts are required for service power. This paper demonstrates how a gas-turbine-driven ship service generator set can be used to supply multiple functions, including electrical power, thermal power, pneumatic power, and direct shaft-driven equipment. The thermal power can be used to perform heating, distillation plant operation, galley services, and air conditioning functions. The Canadian DDH 280 Class destroyer system is presented as an example of a total energy system. Heat recovery boiler and gas turbine characteristics are presented for 600-hp and 5000-hp marine gas turbines. A gas turbine total energy system is compared to a conventional diesel system without heat recovery.
