摘要：Provided is a boiler having plurality of burners (19) arranged on a furnace wall(10) of a furnace (18), each burner (19) comprising: a cylindrical fuel nozzle (3) for injectinga mixture of fuel and carrier gas therefor into the furnace (18); one or more cylindrical airnozzles (8, 11) provided on the outer circumference of the nozzle (3) for injectingcombustion air into the furnace, and a wind box (12) for supplying combustion air to thenozzles (8, 11) in common. The wind box (12) is provided with openings (12a, 12b) throughwhich combustion air flows in from one direction perpendicular to the axial direction ofthe burner (19), and is partitioned by a partition wall (14) to form plurality of parallelflow paths for the air flowing in through the openings. Some of the plurality of flow pathsare connected to an upper part of the combustion air nozzle (8), and the other flowpaths are connected to a lower part of the nozzle (8). Each of the plurality of combustionair flow paths is independently provided with an air momentum deviation damper (15)and an air flow rate adjustment damper (17), such that the direction of the flame of theburner (19) can be changed between upward and downward directions inside the furnace(18) depending on a combustion condition such as a load.
