Gas turbines have an avoidable characteristic in which the power output decreases due to an increase in ambient temperature. Because of heavy electric power demand in summer, the characteristic is critical issue. For decreasing the inlet temperature efficiently, the mist atomization technology was paid attention to. The reason for this is that the technology has efficient air cooling ability with highly-efficient evaporation properties due to minute mist particles. Gas turbine at Higashi Niigata thermal power station has unique inlet air path. The unique path was intended to be utilized for the mist evaporations. In this study, model experiments were conducted for evaluation of the mist atomization effectiveness. At the same time, numerical analysis for the inlet air path was also conducted in order to determine to an optimal position of atomization nozzles. Then, the designed mist atomizing system was installed into the actual commercial plant, 4-4GT at Higashi Niigata thermal power station, and the power output increase was obtained successfully.
