The present invention provides a humid air turbine having a compressor, a humidificator for generating humid air by adding moisture to compressed air supplied from the compressor, a combustor, a turbine, a recuperator for effecting heat exchange between exhaust from the turbine and the humid air, an economizer for effecting heat exchange between exhaust from the recuperator and water, and a system for supplying the water heated by the economizer to the humidificator. The humid air turbine includes a temperature measurement device for measuring the temperature of gas discharged from the economizer, and a control device for adjusting the amount of moisture to be supplied to the humidificator in accordance with a temperature signal from the temperature measurement device. The present invention assures low NOx of combustor and flame stability before and after water addition to the humid air turbine.

What is claimed is: 1. A humid air turbine having a compressor for compressing air, a humidificator for generating humid air by adding moisture to compressed air supplied from the compressor, a combustor for generating combustion gas by allowing the humid air and fuel to mix and burn, a turbine driven by the combustion gas, a recuperator for effecting heat exchange between exhaust from the turbine and the humid air, an economizer for effecting heat exchange between exhaust from the recuperator and water, and a system for supplying the water heated by the economizer to the humidificator, the humid air turbine comprising:a control device for adjusting an amount of water to be supplied from the economizer to the humidificator so that a temperature of the combustion gas in the combustor remains substantially constant at a preset load increase rate, when the water supply to the humidificator begins.
