Title (EN) AIR-COOLED CONDENSER SYSTEM
(FR) SYSTÈME À CONDENSEUR REFROIDI PAR AIR
Abstract:
(EN) An air-cooled condenser system for steam condensing applications in a power plant Rankine cycle includes an air cooled condenser having a plurality of interconnected modular cooling cells. Each cell comprises a frame-supported fan, inlet steam header, outlet condensate headers, and tube bundle assemblies having optionally finned tubes extending between the headers. The tube bundle assemblies may fabricated into an A-shaped tube structure. The tube bundles are self-supporting without support from any part of the frame between top and bottom tubesheets of each bundle. The condensate headers may be slideably mounted to the frame for thermal expansion/contraction. Steam circulating in a closed flow loop on the tube side from a steam turbine is cooled in each cell by ambient air blown through the tube bundles, thereby forming liquid condensate returned to the Rankine cycle. The present design further provides a longitudinal and vertical thermal expansion restraint system.
(FR) Un système à condenseur refroidi par air destiné à des applications de condensation de vapeur pendant un cycle de Rankine d'une centrale électrique comprend un condenseur refroidi par air pourvu d'une pluralité de cellules de refroidissement modulaires interconnectées. Chaque cellule comprend un ventilateur supporté par une armature, un collecteur de vapeur d'entrée, des collecteurs de condensat de sortie et des ensembles faisceaux tubulaires comportant éventuellement des tubes à ailettes s'étendant entre les collecteurs. Les ensembles faisceaux tubulaires peuvent être fabriqués en une structure tubulaire en forme de A. Les faisceaux tubulaires sont autoportants, sans support depuis une quelconque partie de l'armature entre les plaques tubulaires supérieure et inférieure de chaque faisceau. Les collecteurs de condensat peuvent être montés de manière coulissante sur l'armature en vue d'une dilatation/contraction thermique. La vapeur circulant dans une boucle d'écoulement fermée sur le côté du tube à partir d'une turbine à vapeur est refroidie dans chaque cellule par l'air ambiant soufflé à travers les faisceaux tubulaires, ce qui forme un condensat liquide renvoyé au cycle de Rankine. La présente invention concerne également un système de limitation de dilatation thermique longitudinale et verticale.
