Mitsubishi Heavy Industries, Ltd. (MHI) has been developing a Gas Turbine Combined Cycle (GTCC), which is more efficient and operable than conventional thermal power plants. The combustor of a large gas turbine has technological issues such as suppressing combustion instability and reducing NOx emissions, and it is important to evaluate the state of the flame in the combustor in order to solve these issues. In this report, we introduce "three-dimensional visualization of flame in gas turbine combustor", one of the measurement technologies we have developed to understand the flame distribution in a combustor.
