Abstract: Embodiments provide a method and apparatus to lower the temperature and heat content of the ambient air at the inlet to a gas combustion turbine to enhance power generation. Embodiments can use multiple, staged direct contact air chillers, variable flow secondary water chilling systems, constant flow primary water chilling systems with water chilling units arranged for parallel chilled water flow, and a coolant water circulation system used for heat rejection with open cooling towers. Alternatives can use a chilled water thermal storage system, and/or waste heat to drive at least part of the water chilling process. With the included apparatus a method to allow adiabatic air chilling is available for operation during periods of lower ambient air conditions when needs for power augmentation may not be as great.

Abstract: A method and system for enhancing power generated by a gas turbine system. The system may include a turbine inlet cooling system and a wet compression air fogging system. Air entering the gas turbine system is cooled by the turbine inlet cooling system and the wet compression air fogging system. The wet compression air fogging system may increase the mass flow rate of the air entering the gas turbine system at the compressor.

Abstract translation: 实施例提供了一种降低气体燃烧涡轮机入口处的环境空气的温度和热含量以增强发电的方法和装置。 实施例可以使用多个分级的直接接触空气冷却器，可变流量二次水冷却系统，具有用于平行冷却水流的排水单元的恒流一次水冷却系统，以及用于具有开放式冷却塔的排热的冷却水循环系统。 替代方案可以使用冷冻水热存储系统和/或废热来驱动至少一部分水冷却过程。 使用附带的设备，在较低的环境空气条件期间允许绝热空气冷却的方法可用于操作，当需要功率增加时可能不是那么大。
