An air cooled condenser, and methods of manufacturing and field assembly of air cooled condensers in which one half of the primary heat exchanger coils are shop fitted with a length of steel configured to quickly and easily mate, during field assembly, with an opposing primary heat exchanger coil of standard configuration, thereby reducing material, shipping, and handling costs, improving positioning and orientation of HECs during assembly, and reducing the requirement for expensive field welding.

A heated flue includes a flue section configured to be fluidly coupled to an exhaust outlet of a boiler. At least one heater is mechanically coupled to the flue section to heat an exhaust gas flowing within. A sensor is mechanically coupled to the flue section or disposed within the flue section. The sensor is configured to measure a parameter of the exhaust gas flowing within. A controller is operatively coupled to the at least one heater and the sensor. The controller is configured to control a temperature of the exhaust gas based on the parameter. A method to vent a condensing boiler into a non-condensing rated stack is also described.

The present invention provides a power plant whose motive fluid is geothermal fluid, comprising: a high-pressure steam turbine to which geothermal fluid is supplied to produce power; a high-pressure condenser to which the geothermal fluid exhausted from the high-pressure turbine after being expanded therein is supplied and condensed, said high-pressure condenser being configured with a port through which non-condensable gases contained in the geothermal fluid supplied to the high-pressure turbine are extractable in an extraction process and further configured to use heat being released during condensation of the high-pressure steam turbine exhaust to vaporize the steam condensate produced therein for producing low pressure steam without non-condensable gases; and a low-pressure steam turbine for producing power from said low-pressure steam without non-condensable gases supplied from said high-pressure condenser.

Modular air cooled condenser apparatus and related methods are disclosed. An example mechanical draft modular air cooled condenser includes a first condenser bundle panel, a second condenser bundle panel, a third condenser bundle panel, and a fourth condenser bundle panel. The example condenser also includes a fan positioned to create a draft to flow over the first, second, third, and fourth condenser bundle panels.

Modular flow control systems include several differently-shaped structures to achieve desired flow characteristics in fluid flow. Systems include one or many plates held in desired positions by a retainer within the flow. The plates are uniquely shaped based on their position, or vice versa, to shape flow in a desired manner. The plates may fill an entire flow area or may extend partially throughout the area. Plates can take on any shape and are useable in systems installed in any type of flow conduit. When used in a PCCS upper manifold in a nuclear reactor, a chevron plate directly below the inlet divides flow along the entire upper manifold. Perforated plates allow flow to pass at ends of the PCCS upper manifold. The plates can be installed along a grooved edge during an access period and held in static position by filling the length of the PCCS upper manifold.

Large scale field erected air cooled industrial steam condenser having heat exchanger bundles constructed with an integral secondary section positioned in the center of the heat exchanger, flanked by identical primary condenser sections. A bottom bonnet runs along the bottom length of the heat exchanger bundle, connected to the bottom side of the bottom tube sheet, for delivering steam to the bottom end of the primary condenser tubes and for receiving condensate formed in those same tubes. The tops of the tubes are connected to a top bonnet. Uncondensed steam and non-condensables flow into the top bonnet from the primary condenser tubes and flow toward the center of the heat exchanger bundle where they enter the top of the secondary condenser section tubes. Non-condensables and condensate formed in the secondary section tubes enter a secondary bottom bonnet inside the primary bottom bonnet and are withdrawn from the secondary bottom bonnet via outlet nozzle. Each cell of the ACC is fed by a single riser which delivers its steam to an upper steam distribution manifold suspended from and directly below the bundle support framework.
