Abstract
Recently, research and development of micro gas turbine or fuel cell centered micro co-generation system is conducted actively. However, few studies were reported on the combined thermal efficiency based on the actual data measured all through the year. In this paper, we report actual data based combined thermal efficiency evaluation of micro gas turbine centered micro co-generation system especially focused on ambient temperature effect. Measurement was conducted at J-Power Chigasaki R&D Center where oil fueled Capstone 25Kw micro gas turbine was equipped as a central component. We calculated the combined thermal efficiency by counting total heat balance.
