发明名称 Power plant air cooled heat exchanger or condenser with pressurized gas entrained cooling liquid mister
摘要 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.

主权项 1. A liquid mist and air cooled heat exchanger system, comprising: an enclosure including therein: a heat exchange conduit for passage of a heated fluid medium that is to be cooled;wherein the heat exchange conduit is one of a gas turbine compressor bleed conduit and a power plant condensate conduit downstream of a HRSG;a pressurized gas misting device for introducing a gas-entrained liquid cooling mist in heat transfer communication with the heat exchange conduit, the pressurized gas misting device including: a misting device housing, for passage of pressurized gas flow there through;a gas inlet in the misting device housing, for receipt of the pressurized gas flow;a cooling liquid inlet downstream of the gas inlet, for introducing cooling liquid in communication with the pressurized gas flow;an entrainment zone in communication with gas inlet and the cooling liquid inlet, for entraining the cooling liquid within the pressurized gas flow;a misting outlet downstream the entrainment zone, for dispersing gas entrained cooling fluid mist into the enclosure, the cooling fluid mist transferring heat from the heated fluid medium through the heat exchange conduit; a pressurized gas supply coupled to the gas inlet; and a cooling liquid supply coupled to the cooling liquid inlet.
