TWO-MATERIAL ATOMIZING DEVICE

摘要

A two-material atomizing device for atomizing a liquid in a gas stream, comprising a liquid supply (1) with a nozzle opening (3), a gas supply (4) arranged around the liquid supply, the nozzle opening ending in the gas supply, a rotationally symmetrical mixing channel (5) as an axial extension of the liquid supply and having an outlet opening (6), a concentric gas branch (8) from the gas supply (4) upstream of the nozzle opening (3) and an annular injection opening (11) at the outlet opening (6), which is connected to the gas branch. The object is to propose a universally usable two-material atomizing device that also allows adaptation to boundary conditions changing during continuous operation. The object is achieved by means for adjusting the cross section of the injection opening (11) being provided.
