Patent ID: 7757475

Claim:
A gas turbine equipment utilizing high humidity, comprising a humidifying means for humidifying compressed gas for combustion, a heat recovery means for recovering exhaust heat from a gas turbine or said compressed air so as to heat humidifying water in said humidifying means, a recuperator for recovering exhaust heat from the gas turbine and heating the compressed gas for combustion, which has been humidified by said humidifying means, a dehumidifying means for dehumidifying and recovering moisture in the exhaust gas having passed through said recuperator, and an exhaust gas reheater for heating the exhaust gas after dehumidification, wherein said gas turbine equipment further comprises: a temperature measuring means for measuring a temperature of the exhaust gas passing through said exhaust gas reheater; a heating temperature adjusting means for adjusting a heat value applied to the exhaust gas by said exhaust gas reheater; and arithmetic processing means for controlling said heating temperature adjusting means, in accordance with a temperature of the exhaust gas measured by said temperature measuring means, so as to increase the temperature of the exhaust gas heated by said exhaust gas reheater to or over a predetermined value.
