Abstract: The present invention relates to an air-cooled condenser apparatus for condensing a steam flow exiting a turbine from for example a power plant. The air-cooled condenser apparatus comprises a series of condenser modules, each module having a series of compact delta-type heat exchanger units and a series of fans. The air-cooled condenser apparatus further comprises a series of independent frame structures FRS(m) wherein the number of frame structures has a lower limit depending on the number of modules. The invention further relates to a method for manufacturing an air-cooled condenser apparatus comprising steps of manufacturing the delta-type heat exchanger units in the factory, placing the units in a container for transportation and erecting the air-cooled condenser apparatus at a site of installation.

Abstract: The present invention relates to a V-shaped heat exchanger for condensing exhaust steam from a turbine. The V-shaped heat exchanger comprises primary, secondary and tertiary single-row condensing tubes placed in a V-shaped geometry. A steam supply manifold supplies the exhaust steam to lower ends of the primary tubes and steam that is not condensed in the primary tubes is collected at upper ends of the primary tubes and transported to the secondary tubes using top connecting manifolds. Steam that is not condensed in the secondary tubes is further transported to the tertiary tubes using a bottom connection manifold. The tertiary tubes are coupled at their ends with an evacuation manifold for evacuating non-condensable gases.

Abstract: Air-cooled condensers and air-cooled condenser streets for condensing exhaust steam from a turbine are disclosed. An example air-cooled condenser street includes one or more rows of V-shaped heat exchangers. Each row includes a main steam manifold to introduce exhaust steam into tube bundles that are placed in an inclined position such that condensate formed in the bundles flows back by gravitation to the main steam manifold. Top steam manifolds are connected to the upper end of respectively each of the tube bundles of the air-cooled condenser street. The series of parallel top steam manifolds are forming a support assembly for supporting one or more fan decks. The fan decks support a plurality of fans to induce an air draft in the V-shaped heat exchangers.

Abstract: The present invention relates to an air-cooled condenser (1) for condensing steam. The air-cooled condenser comprises one or more roof-shaped heat exchanger assemblies (51,52,53,54,55,56). A plenum space (60) is located between a top boundary delineated by the one or more roof-shaped heat exchanger assemblies (13,14) and a bottom boundary delineated by a deck cover (17). A ducted fan (5) is provided for generating an air-flow. The air-cooled condenser according to the invention comprises an air-flow diffuser (8) having an air inlet side connected to an upper side of the cylindrical duct (7) of the ducted fan and an air outlet side coupled with the deck cover such that, when in operation, an air-flow generated by the fan is flowing through the air-flow diffuser before entering the plenum space via a deck opening (18) in the deck cover. The cross sectional area and the height of the air-flow diffuser are optimized to reduce the electrical power consumption of the fan.
