Title (EN) PFBC POWER PLANT
(FR) CENTRALE ELECTRIQUE A COMBUSTION SUR LIT FLUIDISE PRESSURISE
Abstract:
(EN) A PFBC power plant with a combustor (3) enclosed within a pressure vessel (1). The combustor (3) is formed as a polygonal prism with, for example, hexagonal cross section. The bed section (3a) of the combustor (3) accommodates a steam generator constructed from at least three groups (23) of plane tube discs (24), in which groups (23) the discs are oriented parallel to opposite side walls in the combustor (3). Each tube disc (24) may comprise both evaporation and superheater tubes (25a, 25b, 25c) which may comprise tubes in several parallel planes. In a preferred embodiment, each group (23) of tube discs (24) fills up a parallelepipedic space in the lower part (3a) of the combustor (3).
(FR) Centrale électrique à combustion sur lit fluidisé pressurisé avec brûleur (3) enfermé dans une cuve sous pression (1). Le brûleur (3) a la forme d'un prisme polygonal, par exemple de section transversale hexagonale. La partie lit (3a) du brûleur (3) comporte un générateur de chaleur construit à partir d'au moins trois groupes (23) de disques en tube plat (24), les disques étant orientés parallèlement à deux parois opposées du brûleur (3). Chaque disque en tube (24) peut comporter à la fois des tuyaux d'évaporation et des tuyaux surchauffeurs (25a, 25b, 25c) disposés sur plusieurs plans parallèles. Dans un mode d'exécution préférentiel, chaque groupe (23) de disques en tube (24) remplit un espace parallélipipédique dans la partie basse (3a) du brûleur (3).
