Burner

摘要

A burner (20) comprising: a first pipe section (30) having a discharge port (32) that discharges combustion gas formed therein; a second pipe section (40) that extends inside the first pipe section (30) towards the discharge port (32) and into which mixed air flows from the opposite side to the discharge port (32); a third pipe section (50) arranged inside the first pipe section (30), having the second pipe section (40) interpolated therein, and having an opening end positioned on the discharge port (32) side; a blocking section (51) that blocks the opening end; a coupling wall section (41) that blocks the gap between the first pipe section (30) and the second pipe section (40); a partitioning wall (55) coupled to the first pipe section (30) and the third pipe section (50) and having a communication path (56) formed in the partitioning wall (55) that communicates between the discharge port (32) side and the opposite side of the discharge port (32), relative to the partitioning wall (55); and an ignition unit (62) arranged on the discharge port (32) side relative to the partitioning wall (55), which ignites the mixed air.
