A mixing assembly for gaseous flows at different tempera- tures, in particular for heterogeneous exothermic synthesis reactors, comprising an air space (11) for collection of a hot gas flow (A), an annular opening (12) for outlet of the hot gas flow (A) from the air space (11) and a perforated distributor (13) for a cooling gas flow (B) arranged below the air space (11), calls for a constant thickness of the air space (11) in correspondence of the annular opening (12) and a ratio between 0.2 and 1 of the width of the annular opening (12) to the thickness of the air space (11). The present mixing as- sembly allows compensation for local variations in the flow rate of the hot gas flow (A) leaving the air space (11).
Un ensemble de mélange, destiné à des flux gazeux de températures différentes concernant notamment des réacteurs pour synthèse exothermique hétérogènes, comprend un volume gazeux (11) destiné à collecter un flux gazeux chaud (A), une ouverture annulaire (12) de sortie de ce flux gazeux chaud (A) hors de ce volume (11), et un distributeur perforé (13) destiné à un flux gazeux de refroidissement (B), disposé au-dessus de ce volume (11). Cet ensemble implique une épaisseur constante de ce volume (11) communiquant avec l'ouverture annulaire (12), ainsi qu'un rapport variant de 0,2 à 1 entre la largeur de l'ouverture annulaire (12) et l'épaisseur du volume gazeux (11). Cet ensemble de mélange permet de compenser les variations locales du débit du flux gazeux chaud (A) sortant du volume (11).
