The utility model content
The technical problems to be solved in the utility model provides a kind of firewood gasification furnace that secondary ignites of being convenient to carry out.
For solving the problems of the technologies described above, the firewood gasification furnace that is provided comprises body of heater, and its constructional feature is: dividing plate is housed in the body of heater, dividing plate is divided into upper cavity and lower chamber with body of heater, upper cavity is provided with fire door, and lower chamber is provided with ventilation opening, and the middle part of dividing plate is provided with through hole.
After adopting said structure, owing in the body of heater dividing plate is housed, dividing plate is divided into upper cavity and lower chamber with the body of heater inner chamber, and the middle part of dividing plate is provided with through hole, and upper cavity is the combustion chamber that holds faggot, when the combustion chamber needs secondary to ignite, only need open ventilation opening empties the intravital foreign material of cavity of resorption, can ignite, because the space of dividing plate below is big, it is quite convenient to ignite, so this firewood gasification furnace has and is convenient to carry out the advantage that secondary ignites.
The top of described upper cavity is provided with the bell of material mouth and sealing material mouth, the sidewall of upper cavity is provided with the air outlet, be equipped with on the top inner wall of upper cavity and stretch into upper cavity and open up and down trapping tube, the upper end of trapping tube uncovered with a material mouthful corresponding setting, fill out when putting faggot when opening bell secondary in body of heater, inside and outside the trapping tube, can form the flue gas interlayer, prevent to expect a mouthful air that enters and discharge along the air outlet.
As improvement of the present utility model, this firewood gasification furnace also comprises the purification air feeder that is communicated with upper cavity.The combustion gas of coming out in the auto-combustion chamber can purify the back and provides high-quality, stable combustion gas for burner by purifying air feeder.
Described purification air feeder comprises housing, is provided with decontamination chamber and air feeder in the housing, and the decontamination chamber is communicated with by pneumatic tube with described upper cavity, and the outlet of decontamination chamber is communicated with the import of air feeder.
As further improvement of the utility model, the wire group of irregular winding is housed in the decontamination chamber, and the bottom of decontamination chamber is communicated with the blow-off pipe that stretches out housing, after combustion gas enters the decontamination chamber, group filters through wire, and water that filters and tar etc. can be discharged by blow-off pipe.
As further improvement of the utility model, be connected with blast pipe on the pneumatic tube, can provide oxygen-rich air for burner, make combustion gas perfect combustion.
Described air feeder is an induced draft fan.
As further improvement of the utility model, be communicated with the air-supply duct that stretches out housing and combustion gas can be provided for burner on the induced draft fan, be communicated with smoke exhaust pipe on the air-supply duct.When not using, smoke exhaust pipe can be discharged flue gas.
