Abstract: A jet nozzle includes a single-piece body having a water inlet with a first inlet channel coaxial with a first inlet axis, a gas inlet with a second inlet channel coaxial with a second inlet axis, and an outlet coaxial with an outlet axis, the single-piece body defining a fluid passageway from the first inlet channel to the outlet. A channel wall having a water channel is positioned in the fluid passageway between the first inlet channel and the outlet, the water channel being coaxial with the outlet axis and having a diameter that is smaller than a diameter of the first inlet channel. The second inlet axis is substantially perpendicular to and intersects the outlet axis at a point within the water channel.
