Title (EN) SEALING OF AIR HEATERS BY DEFORMING SECTOR PLATES
(FR) ETANCHEITE DES RECHAUFFEURS D'AIR REALISEE AU MOYEN DE PLAQUES DE DEFORMATION A SECTEURS
Abstract:
(EN) A sealing structure for an air preheater is provided for maintaining a constant clearance between the drum (48) and deformable sector plates (176). Deflection governing struts or beams (120) extend across the sector plates (176) and bend in a manner which corresponds with the change in shape which the drum (48) undergoes when its temperature changes. The outer ends of the struts are connected to an outer ring (110) engages with the drum via guides (100). As the drum (48) deforms so that its ends assume approximately partial spherical curvatures in response to increased temperatures, the struts (120) are likewise deformed. The deformation of the sector plates (176) is controlled by the more rigid struts (120).
(FR) Est présentée une structure d'étanchéité pour réchauffeur d'air, destinée à maintenir un espace constant entre le tambour (48) et les plaques déformables à secteurs (176). Les rayons ou les lattes responsables de la déflection (120) s'étendent sur les plaques à secteurs (176) et se courbent de sorte à correspondre au changement de forme que subit le tambour (48) lors des changements de température. Les extrémités externes des lattes sont connectées à un anneau externe (110) qui s'engage avec le tambour par des guides (100). Lorsque le tambour (48) se déforme de sorte que ses extrémités prennent la forme approximative de courbes sphériques partielles en réponse à l'augmentation de température, les lattes (120) sont également déformées. La déformation des plaques à secteurs (176) est commandée par les lattes les plus rigides (120).
