A combined cycle power plant system and methods of operation so as to minimize consumption of cooling water utilizes exhaust from a combustion turbine to generate steam for power generation in a steam turbine topping cycle. The exhaust steam from the steam turbine topping cycle is utilized to vaporize an organic working fluid in an organic working fluid bottoming cycle, where vaporized organic working fluid expanded across a turbine generates additional power. Exhaust gas from the organic working fluid bottoming cycle is condensed utilizing an air-cooled heat exchanger. Heat exchange bundles of the air-cooled heat exchanger are preferably arranged horizontally relative to the ground to maximize efficiency. Turbine inlet cooling is employed at the combustion turbine to recapture energy lost in the system. A thermal energy storage tank may be utilized in conjunction with the turbine inlet cooling to supply chilling water to the system.

Process utilizing high performance air-cooled combined cycle power plant with dual working fluid bottoming cycle and integrated capacity control

A method for cooling inlet air to a gas turbine is provided. For example, a method is described including passing inlet air through a cooling coil that includes an opening for receiving the inlet air and that is operably connected to a gas turbine power plant. The gas turbine power plant may include at least one gas turbine, and at least one gas turbine inlet which receives the inlet air. The method may further include passing circulating water through a water chiller at a first flow rate to reduce the temperature of the circulating water, the water chiller including a conduit through which the circulating water is capable of passing and passing the circulating water having the first flow rate through the cooling coil in an amount sufficient to lower the temperature of the inlet air. Additionally, the method may include reducing the flow rate of the circulating water passing through the water chiller, passing the circulating water through a water chiller at a second flow rate to reduce the temperature of the circulating water, the second flow rate being lower than the first flow rate, and passing the circulating water having the second flow rate through the cooling coil in an amount sufficient to lower the temperature of the inlet air.A method and system for cooling inlet air to a gas turbine is provided. In order to maintain a desired level of efficiency for a gas turbine plant, water is passed through a chiller to lower the water temperature. The cooled water is then circulated through coils disposed in the inlet air of the gas turbine, thereby cooling the inlet air to the gas turbine. The system may include a thermal energy storage tank for storing chilled water prior to circulation through the coils. The system may also utilize an air temperature set point selected to achieve a desired output or to meet load requirement for the gas turbine plant. The temperature or flow rate of the cooled water may be adjusted to achieve the selected air temperature set point.

System and method for chilling inlet air for gas turbines

High performance air-cooled combined cycle power plant with dual working fluid bottoming cycle and integrated capacity control

A modular data center is constructed utilizing two building modules, wherein each of two modules includes a computer rack disposed therein which computer rack is spaced apart from an exterior wall to define an exterior access space and spaced apart from an interior opening to define an interior access space. When the two building modules are joined so that the openings abut one another, the interior access spaces of the two modules form a contiguous space between the two computer racks, which space satisfies access requirements for each computer rack. The interior access space between the two computer racks may be enclosed to form an environment that can be separately cooled from the remainder of the modular data center. A method provides two building modules, each containing a computer rack, which modules are joined so that the access spaces for the computer racks overlap, wherein a portion of the computer rack access space of one module forms part of the computer rack access space of the other module.
