A method and apparatus for introduction of a first fluid into a second fluid, that flows in a conduit. A first member with a pass-through canal for said second fluid, is at least partially encircled by a chamber with a wall between the inner part of the chamber and the pass-through canal, and a pressurized source of first fluid which is to be supplied into the chamber. At least one series of apertures is distributed about the periphery of the wall, extending there through, such that the first fluid is introduced through the apertures to be mixed into the second fluid based upon the pressure differential between the pressure in the chamber and the pressure in the pass-through canal. At least a portion of the apertures may be selectively blocked or closed to regulate the flow of the first fluid into the pass-through canal.

1. 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.
