Evaluation of Topping and Bottoming Cycle Hybrid Power Plants With MCFC-Micro Turbine

Abstract

The increasing use of electronic appliance has put a strain on the existing electrical supply system. The growing trend of distributed generation could result in small turbo generators being used in the home or rural area. Because small turbo-generator is ideally suited for coupling with a Molten Carbonate Fuel Cell (MCFC) stack, a high efficiency and flexible hybrid system representing a new total energy concept for the distributed power market is presented. This paper presents hybrid concept of bottoming and topping cycle MCFC-micro turbine system. The simulation models for micro turbine, MCFC stack and hybrid system are established. Based on an existing 10kW MCFC stack, we carried out the simulation on hybrid system. The results of the simulation are presented and discussed with particular regards to the selection of design point of different configurations of Hybrid System and design point performance of topping cycle and bottoming cycle Hybrid System.
