| Zusammenfassung: | The invention discloses a multi-stage combustion control clean combustion system which comprises a first incineration device, a dust removal device, a second incineration device, a heat recovery device and a chimney which are sequentially connected through flues; the flue between the heat recovery device and the chimney is connected with a backflow header pipe; the backflow header pipe is branchedinto a first backflow branch pipe communicating with the first incineration device and a second backflow branch pipe communicating with the second incineration device; and the incineration temperature of the first incineration device is kept at 650-1000 DEG C, the temperature of gas at an outlet of the second incineration device is kept at 900-1300 DEG C, and the dust content of gas at an outletof the dust removal device is smaller than 10 mg/Nm . The multi-stage combustion control clean combustion system is simple in structure, low in pollution and high in energy efficiency, the incineration temperature of all stage |
