ABSTRACT:
A mixing apparatus for mixing a vaporized liquid fuel with air to develop a combustible air/fuel mixture is described. A finned swirl inducing member having a centrally located aperture is positioned downstream from a metering venturi and upstream from a plain tube mixing section. The centrally positioned aperture is sized and spaced to allow passage of a stream of vaporized liquid fuel delivered to the low pressure zone formed by a metering venturi. The fin members of the swirler are operative to cause a swirl of the air stream passing through the metering venturi. The swirling air stream prevents any direct contact between the vapor stream and the relatively cool side walls of the mixing section while causing mixing action between the interiorly constrained vaporized liquid fuel stream and the inner portions of the air swirl.
