Abstract
An air cooled heat exchanger, such as a combustion turbine intercooler or rotor cooler or an air cooled condenser, utilizes a pressurized gas fluid entraining misting device that evaporatively cools conduits carrying the cooled fluid medium. Evaporative cooling liquid is entrained in the pressurized gas where it is atomized for evaporative cooling of the heat exchanger conduits. In some exemplary embodiments of the invention the misting device is a jet pump or ejector that entrains a supply of non-pressurized cooling liquid. In other exemplary embodiments of the invention the misting device is a misting emitter that entrains a supply of pressurized cooling liquid.
