Abstract

he use of an Organic Rankine Cycle (ORC) for exhaust gas heat recovery from diesel generator sets allows the production of additional power, and thus supplies an additional energy demand in isolated locations. An energy model of the diesel generator was developed, which allows the determination of parameters such as the specific heat, mass flow rate, and exhaust gas temperature required for system design. R245fa was used as the ORC working fluid. A comparative analysis was performed between the use of conventional diesel generators and the diesel-ORC system in the case of a non-interconnected region in Brazil in terms of energy cost, specific fuel consumption, and electrical efficiency. The results show that a specific fuel consumption of 0.271 L/kWh is obtained with the diesel generator system, while that of the diesel-ORC is 0.248 L/kWh. The energy cost of the diesel-ORC system was 15.56 % lower than that of the diesel generator system.
