MIXING ASSEMBLY FOR GASEOUS FLOWS AT DIFFERENT TEMPERATURES, IN PARTICULAR FOR HETEROGENEOUS EXOTHERMIC SYNTHESIS REACTORS

摘要

A mixing assembly for gaseous flows at different temperatures, 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 assembly allows compensation for local variations in the flow rate of the hot gas flow (A) leaving the air space (11).
