Title (EN) TUBE SHEET ASSEMBLY
(FR) ENSEMBLE DE PLAQUES TUBULAIRES
Abstract: front page image
(EN)THIS invention relates to a tube sheet assembly. In particular the invention is concerned with a tube sheet assembly for a waste heat boiler employed in a chemical process plant and which makes use of metal ferrules for protecting the inlets of the exchange tubes of the tube sheet. The tube sheet assembly is characterized therein that at least one thermal insulator is located inside an inlet opening of a tube sheet of the tube sheet assembly, and covers a portion of a respective ferrule of the tube sheet assembly, thereby providing thermal insulation between the tube sheet and the ferrule.
(FR)La présente invention porte sur un ensemble de plaques tubulaires. En particulier, l'invention porte sur un ensemble de plaques tubulaires pour une chaudière à récupération de chaleur utilisée dans une usine de traitement chimique et qui utilise des férules métalliques pour protéger les entrées des tubes d'échange de la plaque tubulaire. L'ensemble de plaques tubulaires est caractérisé en ce qu'au moins un isolant thermique est situé à l'intérieur d'une ouverture d'entrée d'une plaque tubulaire de l'ensemble de plaques tubulaires, et recouvre une partie d'une férule respective de l'ensemble de plaques tubulaires, fournissant ainsi une isolation thermique entre la plaque tubulaire et la férule.
