An inlet air flow temperature sensor includes a hollow body connected in fluid communication with an inlet air flow a temperature sensing device carried by the hollow body. The hollow body includes interior portions that define a tortuous path of air flow P. The tortuous path of air flow reduces water accumulation on the temperature sensing device. The inlet air flow temperature sensor may be used to sense temperature of an inlet air flow associated with an evaporatively cooled combustion turbine that has a combustion turbine air inlet to receive the inlet air flow. The evaporatively cooled combustion turbine may, in turn, be used to drive an electrical generator.

A power generating apparatus ′ includes an electrical generator ′ and a combustion turbine ′ for driving the electrical generator. The combustion turbine ′ may have a combustion turbine air inlet ′ for receiving an inlet air flow ′. The power generating apparatus ′ may also include an evaporative water cooler ′ for evaporating water into the inlet air flow ′ to cool the inlet air flow, and an inlet air flow temperature sensor ′ between the evaporative water cooler and the combustion turbine air inlet ′. The inlet air flow temperature sensor ′ may include a hollow body ′ connected in fluid communication with the inlet air flow ′, and a temperature sensing device ′ carried by the hollow body. The hollow body ′ may include interior portions to reduce water accumulation on the temperature sensing device ′ so that the temperature sensing device senses a drybulb temperature. The power generating apparatus ′ may also include a controller ′ for controlling the evaporative water cooler ′ based upon the sensed drybulb temperature to cool the inlet air flow ′ to any temperature between the sensed drybulb temperature and a saturation temperature.

A power generating system () includes a generator () and a combustion turbine () for driving the generator (). The combustion turbine () may have a combustion turbine air inlet () for receiving an inlet airflow (). The power generating system () may include an evaporative water cooler () or fogging evaporative system (′) for cooling inlet airflow (), and an inlet airflow temperature sensor () proximate or within the combustion turbine air inlet (). The inlet airflow temperature sensor () may sense a drybulb temperature of the inlet airflow () proximate the air inlet (). A controller (′) is provided for controlling the cooling of inlet airflow () across transient load conditions of the power generating system (′). This control may be based upon the sensed drybulb temperature used to calculate an approach temperature with respect to the inlet airflow (′) that is compared to an approach temperature setpoint based on load. The controller may adjust the flow rate of water of the fogging system (′) to maintain the calculated approach temperature within limits of the setpoint.
