Abstract:
1. In a device for the injection and mixing of steam into a fluid stream, said device comprising a substantially cylindrically-shaped primary conduit having a longitudinal axis and a substantially circular cross-section for carrying said fluid stream, said primary conduit being provided with an inlet for accepting said fluid stream and an outlet for discharging said fluid stream along said longitudinal axis, and a secondary conduit joined to said primary conduit for discharging steam within said fluid stream along said longitudinal axis, the improvement comprising a biscuit element of sintered tungsten having upstream and downstream circular faces of a diameter approximately that of said primary conduit's interior wall and having a geometric center coincident with said longitudinal axis and having a plurality of openings through said biscuit each having a longitudinal axis substantially parallel to the longitudinal axis of said primary conduit and said openings having located therein, mixing elements that induce a rotational angular velocity to said fluid stream passing therethrough and conically-shaped features extending from said circular faces and centered along said longitudinal axis at the geometric centers thereof.
