Gas Turbines For Marine Applications: Exergy Analysis For an Improved Gas Turbine

In marine applications, the gas turbine is usually driving the propellers of ships or a ferry. The major advantage of gas turbines over conventional steam turbines or marine diesel main engines is their excellent power to weight ratio. However, the increasing price of fuel determined a lot of ship companies to return to old marine diesel engines. Fuel cells power systems have attracted attention due to their potential for high efficiencies, low emissions, flexible use of fuels and quiet operation. These benefits recommend fuel cells for the marine use. This paper deals with the exergy analysis applied to gas turbines in order to assess exergy losses in processes developed in the combustion chamber and in a fuel cell replacing it, in order to measure thermodynamic efficiency. It is found that exergy losses in the improved gas turbine are lower compared to the traditional one. This means that the gas turbine having a fuel cell instead of a combustion chamber presents a lower energy demand and works environmentally sensitive.
