Abstract:
Apparatus for introduction of a first fluid into a second fluid, that flows in a conduit, comprising:a first member with a pass-through canal for said second fluid; at least one longitudinally extending chamber that extends around at least a main part of the periphery of the pass-through canal; a wall between an inner part of the chamber and the pass-through canal; means for supplying the first fluid to said chamber from a pressurized source for sustaining a higher pressure in the chamber than in the pass-though canal; and at least one series of continuous apertures, each aperture being formed as an elongated slot, having a first rounded end, a second rounded end opposed to the first rounded end, and parallel side walls disposed between the first and second rounded ends, and having a longitudinal axis, each of the apertures extending through said wall, through which the first fluid can be introduced and mixed into the second fluid that flows through said pass-through canal by a pressure differential between a fluid pressure in said chamber and fluid pressure in said pass-through canal.
