Feasibility of mini combined cycles for naval applications

Abstract: The objective of energy production with low environmental impact will have, in the near future, high potential of development also for naval applications. The containment of pollutant emissions can be achieved by the combined use of an innovative mini gas-steam combined cycle with thermal energy cogeneration to feed the ship thermal utilities, in place of the current Diesel engine application, and liquefied natural gas as fuel (LNG). The present work is focused on the definition of the architecture of the plan… Show more

“…Inland-distributed generation in the context of the growing amount of renewable energy systems on the grid [1] and key applications such as clean water production via desalinization [9] would benefit from the use of compact combined heat and power (CHP) GT units, from both economic and performance perspectives. A similar need for compact machinery has been observed in the fields of aircraft propulsion [10] and naval onboard energy generation [11,12], where such machines are seen as valid options for compact layouts. Indeed, radial turbomachines benefit from their small overall dimensions, while maintaining interesting performance at low size [4,5,13].…”

“…The water temperature at the economizer inlet had been considered equal to 90 • C. The values of gas turbine exit temperature and mass flow rate (546 • C and 23.96 kg/s, respectively) were obtained again from the in-house developed code for cycle analysis, considering the cycle parameters (pressure ratio, components efficiencies) and the cycle thermal balances. The component efficiency values were determined from statistical analyses of data presented in the literature for machines of similar size to that of the present application and from previous works by the authors [26,27].…”

“…If considerable thermal power demand exists onboard, COGES plant cogeneration efficiency is further improved due to the large amount of thermal power available in gas turbine exhaust gas. In these cases, even when power requirements are contained, COGES plants can be adopted to increase cogeneration efficiency [22,23]. In particular, Barsi et al [24] proved that mini-GT cycles can be a valuable choice to cover thermal and electrical generation demand onboard medium size cruise and Ropax ships due to their competitive cogeneration efficiency.…”
