Abstract

The utility model discloses a strong hot-air double-hearth high-temperature boilling furnace including a furnace body, hearths, a high pressure fan, a fire stop wall, the hearths provided at the bottom of the furnace body and between the front wall and fire stop wall of the furnace body, a discharge pipe of the high pressure fan communicated with the hearth, also including combustion-aid wind pipe, auxiliary hearth, auxiliary fire stop wall, auxiliary wind pipe, the auxiliary fire stop wall provided behind the fire stop wall, the auxiliary hearth provided between the fire stop wall and the auxiliary fire stop wall, one end of the auxiliary wind pipe communicated with the discharge pipe of the high pressure fan and the other end communicated with the auxiliary hearth, one end of the combustion-aid wind pipe communicated with the discharge pipe of the high pressure fan, and the other end communicated with the inner wall of boiler above the hearth. The present utility model can fully burn the coal in the boiler, which greatly improves the burning efficiency of the boiling boilers.

Description

Heat-flash wind twin furnace height of bed temperature fluidized bed furnace
Technical field
The utility model relates to a kind of device that utilizes fire coal to act as a fuel to produce high temperature hot gas, particularly a kind of heat-flash wind twin furnace height of bed temperature fluidized bed furnace.
Background technology
At present, be generally fluidized bed furnace for dryer provides the equipment of high-temperature hot-air in cement production process, it comprises body of heater, siege, high pressure positive blower, flame shield, and siege is arranged on the bottom of body of heater, siege is between the antetheca and flame shield of body of heater, and the discharge pipe of high pressure positive blower and siege be communications and liaison mutually.Because this fluidized bed furnace has only single siege, fire coal is carried out disposable burning, and the air quantity distribution is reasonable inadequately, therefore is difficult to guarantee coal-fired completing combustion, thereby causes the efficiency of combustion of fluidized bed furnace low.
The utility model content
The technical problems to be solved in the utility model provides a kind of heat-flash wind twin furnace height of bed temperature fluidized bed furnace, and it can make coal-fired fully burning in stove.
For solving the problems of the technologies described above, the utility model heat-flash wind twin furnace height of bed temperature fluidized bed furnace, it comprises body of heater, siege, high pressure positive blower, flame shield, siege is arranged on the bottom of body of heater, siege is between the antetheca and flame shield of body of heater, the discharge pipe and the siege of high pressure positive blower link, also comprise combustion-supporting airduct, auxilliary siege, auxilliary flame shield, auxilliary airduct, auxilliary flame shield is arranged on the back of flame shield, auxilliary siege is arranged between flame shield and the auxilliary flame shield, one end of auxilliary airduct and the discharge pipe of high pressure positive blower link, its other end and auxilliary siege link, and the discharge pipe of combustion-supporting airduct one end and high pressure positive blower links, its other end and siege top inboard wall of furnace body is communications and liaison mutually.
Because be provided with the combustion-supporting airduct of air intake on inboard wall of furnace body above the siege, it can constantly send into fresh air in stove, thereby fire coal is fully burned on siege.Simultaneously owing to be provided with auxilliary siege in the back of flame shield and link by the discharge pipe of auxilliary airduct with blower fan, the unburnt coal grain of part enters with high-temperature hot-air and assists siege and burn in siege.Therefore fire coal can be fully burned in stove, thereby has improved the efficiency of combustion of fluidized bed furnace greatly.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
1. high pressure positive blowers in the accompanying drawing, 2. combustion-supporting airduct, 3. coal feeding pipe, 4. discharge pipe, 5. siege, 6. body of heater, 7. flame shield, 8. auxilliary airduct, 9. auxilliary siege, 10. auxilliary flame shield, 11. hot wind outlets.
The specific embodiment
In the accompanying drawing, siege 5 is arranged on the bottom of body of heater 6, and siege 5 is between the antetheca and flame shield 7 of body of heater 6.The discharge pipe 4 and the siege 5 of high pressure positive blower 1 link.Auxilliary flame shield 10 is arranged on the back of flame shield 7, and auxilliary siege 9 is arranged between flame shield 7 and the auxilliary flame shield 10.One end of auxilliary the airduct 8 and discharge pipe 4 of high pressure positive blower 1 links, its other end and auxilliary siege 9 link.Combustion-supporting airduct 2 one ends link with the discharge pipe 4 of high pressure positive blower 1, the inwall of its other end and siege 5 top bodies of heater 6 communications and liaison mutually.The rear wall of body of heater 6 is provided with hot wind outlet 11.During work, coal-fired fall into siege 5 burnings from coal feeding pipe 3, under the effect of air and flue gas about strenuous exercise, the very fast and spent coal of fire coal of newly going into stove mixes, and is heated burning rapidly.Meanwhile, because combustion-supporting airduct 2 is sent constantly into fresh air, make the stove internal combustion abundant.The unburnt coal grain of part enters auxilliary siege 9 with high-temperature hot-air and burns, and its time of staying 40-75 second, therefore unburnt coal grain is fully burned.The high-temperature flue gas that the last coal-fired afterburnt produces discharges out of the furnace by hot wind outlet 11, enters in the drying plant.
