Patent ID: 10399046

Abstract:
A device for the injection and mixing of steam into a fluid stream. The device includes a cylindrically-shaped primary conduit having a longitudinal axis and circular cross-section for carrying the fluid stream. The primary conduit is provided with an inlet for accepting the fluid stream and an outlet for discharging the fluid stream along the longitudinal axis. A secondary conduit is joined to the primary conduit for discharging steam within the fluid stream along the longitudinal axis. A biscuit element is provided having upstream and downstream circular faces of diameters approximately that of the primary conduit's interior wall and having a geometric center coincident with the longitudinal axis and further having a plurality of openings through the biscuit each having a longitudinal axis substantially parallel to the longitudinal axis of the primary conduit and each of the openings having located therein a plurality of microtubes such that steam passing through the secondary conduit and fluid passing through the primary conduit pass through the microtubes and are mixed thereby.
