Description
Technical field:
The present invention relates to the improvement of straw burning furnace structure.
Background technology:
Present straw burning device has multiple, but great majority are continued to use the burning form of coal stove, is difficult to performance straw burning characteristic, and therefore, efficiency of combustion is not high.
Summary of the invention:
The present invention is exactly at the problems referred to above, and a kind of straw burning and high gasifying stalk combustion furnace of efficiency of combustion of being more suitable for is provided.
For achieving the above object, the present invention adopts following technical scheme, the present invention includes body of heater, is the combustion chamber in the body of heater, and its structural feature is that the bottom of combustion chamber is the slag baffle plate that falls with air vent, and the outlet at bottom place of the slag baffle plate that falls is the screw rod of slagging tap; The furnace wall with air vent of combustion chamber is with being secondary air duct between the furnace body shell; The outlet of combustion chamber is the eddy flow spout with helical blade; The feeding mouth place of combustion chamber is provided with electric heater, electric heater with in have feeding spiro rod, on have a Bunker conveying pipeline link to each other, be provided with ignition air duct in the feeding spiro rod.
Beneficial effect of the present invention:
1, efficiency of combustion height:
The air vent of the present invention by the slag baffle plate that falls enters a wind in the combustion chamber, reach the secondary wind that enters the combustion chamber by the air vent on the furnace wall, make fuel in the combustion chamber, form strong vortex, at this moment, fuel fully mixes with air, has not only prolonged burning time, and, make full combustion of fuel, improved efficiency of combustion;
2, igniting is simple:
When the present invention lights a fire, utilize the electric heater heating fuel, the ignition air duct in feeding spiro rod feeds micro-wind then, makes ignited fuel, and therefore, ignition process is simple;
3, fan-out capability is strong:
Because exit of the present invention is provided with the eddy flow spout with helical blade, the whirlwind of the height of sending rotation, high-temperature is easier to heat heated equipment;
4, deslagging is effective:
The present invention adopts the screw rod deslagging of slagging tap, and makes the residue of stalk be not easy to accumulate, and discharge at any time also helps simultaneously good combustion efficiency;
5, be widely used:
Because combustion efficiency of the present invention is good, can be widely used in the improvement of various stoves, its operating cost is lower by 40% than coal-burning boiler, than oil burning boiler low 70%.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1;
Fig. 4 is that the K of Fig. 1 is to view.
The specific embodiment:
The present invention includes body of heater 13, is combustion chamber 12 in the body of heater 13, and the bottom of combustion chamber 12 is the slag baffle plate 2 that falls with air vent 3, and outlet at bottom 1 place of the slag baffle plate 2 that falls is the screw rod 21 of slagging tap; The furnace wall with air vent 10 14 of combustion chamber 12 is with being secondary air duct 16 between body of heater 13 housings 15; The outlet of combustion chamber 12 is the eddy flow spout 17 with helical blade 25; The feeding mouth place of combustion chamber 12 is provided with electric heater 9, electric heater 9 with in have feeding spiro rod 5, on have a Bunker 6 conveying pipeline 7 link to each other, be provided with ignition air duct 4 in the feeding spiro rod 5.
Air pump 19 links to each other with secondary air duct 16 by pipeline 20; Air pump 19 links to each other with the ignition air duct in the feeding spiro rod 54 by the pipeline 18 with switch valve 22.
Be the deslagging better effects if, can be provided with three screw rods 21 of slagging tap in the bottom of the slag baffle plate 2 that falls; Slagging tap screw rod 21 and feeding spiro rod 5 all can be by 23 driving of same motor.
Outside the bottom of body of heater 13, slag baffle plate 2 places that fall relatively are provided with blower fan 24; Fall air vent 3 air-supply of slag baffle plate 2 of 24 pairs of blower fans.
The top of body of heater 13 is provided with form 11, so that observe the combustion case in the combustion chamber 12.
Below in conjunction with a description of drawings course of action of the present invention:
Send into stalk fuel by Bunker 6, it is sent in the combustion chamber 12 through feeding spiro rod 5; Start electric heater 9, stalk fuel is heated when being preheated to 300 ℃-400 ℃, open switch valve 22 and be blown into micro-wind, the stalk of the dark combustion of gasifying is blown out naked light, thus the fuel in the ignition combustion chamber 12.At this moment, close electric heater 9, open feeding spiro rod 5 simultaneously, blower fan 24 is sent into a wind in the combustion chamber 12 by the air vent 3 on the slag baffle plate 2 that falls.Secondary wind is sent into 20-36KPa by air pump 19 and is pressed wind-force, and the pressure air of secondary wind is preheating to 90 ℃-380 ℃ through furnace wall 14, adopts ejector principle, tangentially enters combustion chamber 12 by air vent 10, forms the vortex that moves downward; In the decline process, combine, send by eddy flow spout 17 with volatilization gas and fuel in the flame; Under cyclonic action, unburnt particle and soot particle are separated in the flame, fall into slag baffle plate 2, by screw rod 21 outputs of slagging tap.
