??Currently, 60㎾ class gas turbine - fuel cell hybrid power generation system is being developed by Korea Aerospace Research Institute. Because of connection problems between gas turbine and fuel cell, the combustor is necessarily to have flame stability and wide flamability range at the starting stages. Furthermore, in order to enhance the efficiency of the whole system, high combustion efficiency and low pressure loss are required. It also should satisfy the temperature limitations of turbine blade by supplying sufficiently low and uniform thermal energy. In the present study, for the optimization of the combustor, its stability characteristics are tested with change of various operating conditions such as injector shape, swirler air mass flow rate etc.
