Abstract

An inlet device for an air/gas flow, particularly for the admission of said flow into a centrifugal fan (2) of a pre-mixing burner apparatus, comprises flow conveying means (6) arranged for conveying the flow of air and/or gas to the intake section (5a) of the fan,wherein the conveying means (6) are of the centripetal flow type and comprise a plurality of stator conveying ducts (7) extending in directions having a predominant radial component with respect to the axis of rotation (X) of the fan and are angularly spaced from one another along a circumferential profile concentric with the axis.
