Niigata University and TERI collaborated in developing a biomass gas turbine system with an enhanced fuel applicability for rural villages in south Asia. This paper describes a mixed and standard type gas turbine system for this purpose. The mixed type gas turbine employs a regenerated Brayton cycle with a secondary combustor to burn various fuels. The thermodynamic analysis revealed that the mixed type gas turbine system has a capability to achieve the thermal efficiency between a regenerated Brayton cycle and a complete external fired system. An experimental test was done using mixtures of bio diesel fuel and kerosene. It demonstrated that the engine performance changed only slightly with regard to the mixture ratio. In the experiment, a prototype biomass gas turbine was able to achieve the 600 W power generation. The mixed fuel with the mixture ratio of bio fuel up to 60 % was confirmed to be applicable to the current gas turbine system.
