Patent ID: 6923003

Claim:
A power generating apparatus comprising: an electrical generator; a combustion turbine for driving said electrical generator and having a combustion turbine air inlet for receiving an inlet air flow; an evaporative water cooler for evaporating water into the inlet air flow to cool the inlet air flow; a plurality of spaced-apart inlet air flow temperature sensors between said evaporative water cooler and the combustion turbine air inlet, and each of said plurality of spaced-apart inlet air flow temperature sensors comprising a hollow body connected in fluid communication with the inlet air flow, and a temperature sensing device carried by said hollow body, said hollow body comprising interior portions defining a tortuous path of air flow therethrough to reduce water accumulation on said temperature sensing device so that said temperature sensing device senses a drybulb temperature; and a controller for controlling said evaporative water cooler based upon the sensed drybulb temperatures from said plurality of spaced-apart inlet air flow temperature sensors.
