Mixing and/or vaporisation device

摘要

The device (7) has a set of blades (8) arranged in a circumferential direction in distributed manner, where each blade projects inwardly from an outer wall (9). Each blade has a profile (10) in an area adjoining the outer wall in an axial direction (14). A discharge edge (12) of the profile has an offset (16) in the circumferential direction in relation to a leading edge (11). The profile has an angle of incidence (17) in relation to the axial direction at the leading edge and at the discharge edge, where the incidence angle lies in a range from minus 10 degrees to plus 10 degrees.
