Abstract (en)
[origin: EP2233836A1] The swirl generator (31) has outer wall (39) enclosing central fuel distributor (37) and bounding axial flow channel (41) for combustion air. Swirl vanes extend in radial direction to outer wall to give tangential flow component to flowing combustion air. A separating wall (42) encloses central fuel distributor, and is positioned radially within outer wall to divide flow channel into radially inner channel segment (43) and radially outer channel segment (45). The radially inner channel segment allows combustion air to pass without giving tangential flow component to combustion air. An independent claim is also included for the flashback preventing method for use in burner.
