Title
(EN) AIR PREHEATER WITH SEMI-MODULAR ROTOR CONSTRUCTION
(FR) PRECHAUFFEUR D'AIR A CONSTRUCTION DE ROTOR SEMI-MODULAIRE
Abstract
(EN)
The rotor (14) for a rotary regenerative air preheater is fabricated from a combination of shop assembled rotor sector modules (56) and field assembled components so as to eliminate the double plate diaphragms (34) of conventional modular rotors (14). The shop assembled modules (56) comprise one or more sectors (58, 60) and the field assembled components fit between the spaced shop assembled modules (56) spaced around the rotor hub (36). The support gratings (66) between the diaphragm plates (68) support modular heat exchange baskets (22) which are loaded into the rotor (14) radially from the periphery.
(FR)
Le rotor (14) pour un préchauffeur d'air regénératif rotatif est fabriqué à partir d'une combinaison de modules (56) de secteurs de rotor assemblés à l'usine et de composants assemblés sur le site, de manière à supprimer les diaphragmes (34) à doubles plaques de rotor modulaires classiques (14). Les modules (56) assemblés à l'usine comprennent un ou plusieurs secteurs (58, 60) et les composants assemblés sur le site s'insèrent entre les modules (56) assemblés à l'usine espacés autour du moyeu (36) du rotor. Les grilles de support (66) entre les plaques de diaphragme (68) supportent des paniers à échange de chaleur (22) qui sont chargés dans le rotor (14) de manière radiale à partir de la périphérie.
