Abstract: A fuel arrangement for a combustion apparatus, comprises at least one passage for the flow of fluid, the passage being of substantially annular cross section, being defined by a radially inner wall and a radially outer wall and having an inlet region and an outlet region. The inlet region incorporates a plurality of vanes adapted to modify a flow pattern of a fluid entering the inlet region, such that fluid passing from the inlet region to the outlet region has a composite flow pattern having both an axial component and a rotational component about the longitudinal axis of the passage.
