Air current bed boiler

The utility model discloses an air current bed boiler belongs to boiler energy saving and consumption reduction technical field. Including drum (1), furnace (2), preceding downtake (3), back downtake (16), convection gas pass I (21), convection gas pass II (23), turn flue (11) and combustor (20), install combustor (20) the top of furnace (2), furnace (2), convection gas pass I (21) and convection gas pass II (23) are article style of calligraphy structure, constitute the flue gas passageway, convection gas pass I (21) and convection gas pass set up convection gas pass partition wall (22) between II (23). This air current bed boiler adopts anti - fever formula, article style of calligraphy flue, and angled pipe formula air current bed structure for the simple compactness of boiler overall structure is made simply, has saved the consumptive material, has reduced area, reduces the work load of on -the -spot required installation, and makes the boiler combustion stable, is difficult for the coking, has improved boiler efficiency by a wide margin.
