0504 Thermal Efficiency Analysis of 10kW Micro Gas Turbine-Solid Oxide Fuel Cell Hybrid System
Details
A micro gas turbine (μGT) and a fuel cell combined cycle power generation is considered as one of the distributed energy supply sources. This system drives μGT by using the high temperature exhaust of the solid oxide fuel cell and melted carbonate fuel cell. In this investigation, the thermal efficiency analysis of hybrid system, combined with 10kW class μGT and SOFC fueled by propane, was performed. It was demonstrated that the maximum in the thermal efficiency on load balance of SOFC and μGT. Optimization of load balance and fuel supply distribution was performed and the thermal efficiency of 58% was obtained in the part-load. Higher efficiency in part-load is preferable when the system is used for the micro grid and the emergency power supply.
