Modular heat exchange baskets (40) for rotary regenerative air preheaters have radially extending tie bars (52) which are positioned at each of the top and bottom side edges of the basket (40) and which tie together the inboard (46) and outboard (48) end frames. These tie bars (52) are located inside of the side edges (30) of the heat exchange plates (14) such that the plates (14) extend out beyond the tie bars (52). This reduces the bypass gap (36) between baskets (40).
L'invention porte sur des enceintes (40) modulaires d'échangeurs de chaleur destinées à des préchauffeurs d'air rotatifs à régénération, ces enceintes comportant des barres de raccordement (52) s'étendant axialement et positionnées au niveau de chaque bord latéral supérieur et inférieur de l'enceinte (40), et qui raccordent les structures terminales intérieure (46) et extérieure (48). Ces barres de raccordement (52) sont placées à l'intérieur des bords latéraux (30) des plaques (14) d'échange thermique de sorte que celles-ci (14) dépassent les barres (52) de raccordement. Ceci permet de réduire l'intervalle (36) de dérivation entre les enceintes.
