Lean pre-mixing burner for combustion chamber, has main air-ring channel with integrated swirl units that are designed as aerodynamic profiled and/or formed air guide vanes that divert air stream into channel in preset angle

摘要

The burner has a central support burner and a main air-ring channel (4) surrounding the support burner. The channel has integrated swirl units for mixing an axial main air stream with liquid fuel introduced into the stream. The swirl units are designed as aerodynamic profiled and/or formed air guide vanes (5), which divert the air stream into the main air-ring channel in an angle of 40 to 60 degrees towards stream direction.
