Two-Substance Atomizing Device

摘要

A two-substance atomizing device for atomizing a fluid in a gas stream includes: a fluid supply branch including a nozzle orifice; a gas supply branch configured concentrically about the fluid supply branch; a concentric second gas branch branching from the gas supply branch and disposed upstream of the nozzle orifice, the nozzle orifice terminating in the gas supply branch; an axially symmetric mixing channel disposed in axial extension of the fluid supply branch and including a discharge orifice; an annular injection orifice in communication with the gas supply branch and disposed near the discharge orifice; and an adjustment device configured to adjust a cross section of the injection orifice.
