Abstract
A pressure vessel bypass valve forms a bypass system for enabling a part of the air compressed by a compressor to directly flow into a combustor while preventing the part of the air from flowing through a humidification tower and a recuperator. A turbine bypass valve forms another bypass system for enabling a part of a humidified air to be discharged to an exhaust duct after a heat exchange between the humidified air and a turbine exhaust gas is performed in the recuperator while preventing the part of the humidified air from flowing through a turbine. A turbine control system controls the bypass valves to be opened and closed in accordance with increase and decrease of the load.
