Energy saving and environment become important issues in power and propulsion generation industry. One of such examples is the marine transportation where a lot of energy from consumed fuel is wasted in exhaust and emissions are produced in vessel propulsion systems. The focus of this research is to look at a typical marine propulsion system where gas turbines are the prime movers and to investigate the potentials of a novel 3-stage gas turbine combined heat and power (CHP) system for marine applications. Such a CHP system may include a topping gas turbine Brayton cycle, an intermediate water Rankine cycle (WRC), and a bottoming organic Rankine cycle (ORC). In the system, gas turbine is connected with a generator to produce electricity, water Rankine cycle produces superheated steam driving steam turbine for electricity generation and/or for heating, and organic Rankine cycle is used to produce electricity by recycling low temperature energy. A thermodynamic model for the 3-stage CHP system is established to simulate the performance of the system at different power demand operating conditions. The developed performance simulation system has been applied to a typical model vessel propulsion system application. Based on the simulated results, it is evident that compared with a conventional 2-stage CHP cycle where only gas turbine topping cycle and water Rankine bottoming cycle are included, the introduction of the organic Rankine cycle can increase the power output by about 7% and improve the cycle thermal efficiency by about 3.52%.
