摘要

The burner branch (4) contains a burner and has an exhaust gas opening (30) conveying combustion products (28) from the exhaust gas branch (6). A first outer air pipe (34) with outer (40) and inner (42)end is radially positioned in the exhaust gas branch and has a circular passage (38). A second inner mixer pipe (60) has a second circular passage (70) with outer (62) and inner (64) end. A mixer plate(80) has a narrow part at the inner end near a pipe for producing a fluid connection between the first passage containing a flow-directer, and mixer pipe.
