The utility model discloses a boiler flue gas cyclic utilization system, provide fresh air's forced draught blower, dust remover including the boiler, in being used for to the boiler and be used for drawing forth the flue gas draught fan of flue gas, be provided with the circulation flue on near the flue in flue gas draught fan, the other end of circulation flue is connected with the hybrid chamber, and the hybrid chamber still is provided with the air outlet of being connected with the forced draught blower and is used for the air inlet of fresh air intercommunication. The utility model discloses simple structure, not only effective recycling the heat that carries in a large amount of flue gases, the flue gas of drawing forth draught fan part is retrieved to the flue gas of retrieving the circulation part be the heat medium, carries again and participate in the burning in the boiler, before the reentrant boiler, can get into fresh air intensive mixing in the hybrid chamber of boiler, has increased the temperature that gets into the pot furnace air, has reduced the some energy consumption of here. The utility model discloses use draught fan exhaust part flue gas to carry out heat exchange as heat medium, flue gas through the entrance point of dust remover, make the partial flue gas of circulation reach the higher temperature.
