Summary of the invention:
The purpose of this invention is to provide a kind of biomass burner that is applicable to the industrialization continuous burning.Technical solution of the present invention is a kind of biomass burner; Comprise vaporizer and combustion chamber; It is characterized in that: be provided with feeder in the vaporizer outside and be communicated with the bottom of vaporizer, feeder be provided with helical blade spool on the sprocket wheel that is provided with on sprocket wheel and the speed reducer output shaft relative, the top of feeder housing be provided with charging aperture with above the feed bin discharging opening be communicated with; Housing top at the feeder discharging section has fire hole, and its aperture is furnished with cover plate; The vaporizer of combustion chamber and its side in abutting connection with and be communicated with; On the wall of combustion chamber, be provided with crater, wind distributing hole; Be provided with broken slag tapping equipment in the burning chamber shell bottom, the helical blade of this broken slag tapping equipment is the discontinuous helical blades of a plurality of mutual disconnections, stretches in the below of combustion chamber fire grate in this discontinuous helical blade; Bottom at the external end head of broken slag tapping equipment housing has slag notch, and the sprocket wheel that on the axle of this broken slag tapping equipment, is provided with on sprocket wheel and another speed reducer output shaft is relative.The discontinuous helical blade of said broken slag tapping equipment be provided with gripper shoe with screw propulsion surface in the opposite direction.In the pipe tap of distributing device axle rotational support between feed bin and feeder, this axle is provided with blade, the outer end on this be provided with sprocket wheel and feeder the axle on another sprocket wheel relative.The present invention and prior art relatively have the remarkable advantage of continuous burning.
Description of drawings:
Fig. 1 is the front view of biomass burner of the present invention, and Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment:
In conjunction with above-mentioned accompanying drawing the present invention is described in detail, the crater of burner according to supporting boiler design different shapes, if coal-fired manual boiler, the shape of crater can be done squarely or oval and be connected with the fire door of boiler is corresponding; If coal-fired chain furnace, the coaling machine of need dismantling, the shape of crater can be made phase that coaling machine is connected with boiler in specie, substitutes coaling machine and is connected with boiler; If fuel oil, gas fired-boiler, the fuel-firing gas-firing combustor of need dismantling, the shape of crater can be done combustion chamber butt joint circular and oil-burning gas-fired boiler.Boiler does not have air-introduced machine, needs to install air-introduced machine additional at the smoke position of boiler.The discharging opening of feed bin 6 is connected with feed pipe, and the blade 10 on the distributing device places this feed pipe, and feeding screw 9 is communicated with above-mentioned feed pipe; The body of this feeding screw is communicated with the vaporizer 3 in its left side; The top of this body is provided with fire hole, and the aperture is provided with cover plate 11, and vaporizer is communicated with the combustion chamber 12 in its left side; Side in the combustion chamber is provided with crater 13 and docks with coal-burning boiler (also can be fuel oil or gas fired-boiler) coal feed point; Be provided with broken slag tapping equipment 1 in the bottom, combustion chamber and be communicated with the combustion chamber, the helical blade of this broken slag tapping equipment is the bottom that the discontinuous helical blade of disconnection places the combustion chamber, for rigidity and the intensity that strengthens blade; The back side in the blade direction of advance is provided with gripper shoe, has slag notch 14 in the bottom, outer end of broken slag tapping equipment housing.The sprocket wheel that the axle of broken slag tapping equipment is provided with on sprocket wheel 15 and the speed reducer output shaft is relative.The sprocket wheel that the axle of feeder is provided with on sprocket wheel 4 and another speed reducer output shaft is relative.Another sprocket wheel that the axle of distributing device is provided with on sprocket wheel 5 and the feeder axle is relative, and biomass burner of the present invention is provided with two motors and drives above-mentioned two reductors respectively.Be provided with the air distribution chamber in the housing of vaporizer, the inboard in air distribution chamber and the outside be uniformly distributed with wind distributing hole and blast pipe respectively with vaporizer and atmosphere, aid distributing pipe can be provided with many assembly airduct according to the big I of vaporizer.
Operation principle of the present invention is; Biomass fuel is after feeder is sent into feed bin; Start feeder driven by motor reductor and make feeder begin to rotate through sprocket wheel, the sprocket wheel on the feeder drives the sprocket rotation on the distributing device, makes biomass fuel under the effect of distributing device blade, get into feeder equably; Under the promotion of feeder packing auger blade, biomass fuel gets into vaporizer.After the fuel of vaporizer gathers to a certain degree, close the feeder motor, open the fire hole cover plate; With hand fuel is drawn out a little, put into the fuel position of drawing out after lighting with an amount of combustibles, close the fire hole cover plate; Open boiler induced-draft fan, open the feeder motor after a while.Fuel vaporizer behind gasification, and combustion progressively by charing, the fuel after the charing progressively gets into the combustion chamber under the promotion of feeder blade, fall into fire grate 16 tops.Get into the carbonized fuel of combustion chamber and the fuel gas that forms in vaporizer gasification back, behind many places air distributions such as flame-observing hole 8, fire door 2, wind distributing hole 7, form second-time burning, burned flame gets into boiler furnace through crater, substitutes coal, oil, combustion gas acting.Biomass fuel is behind gasification, and combustion; Forming ash content or slag gradually in the combustion chamber accumulates on the fire grate; Behind ash content and slag formation certain altitude; Open broken mucking machine motor, make ash content and slag under the effect of broken helical blade, it is anti-to fall into ash after being released slag notch 14 gradually from the fire grate of bottom, combustion chamber below.
The present invention's existing steam coal layer thickness control technology capable of using can be controlled the ash content height automatically, accomplishes the automation control of slagging tap.The motor of air-introduced machine and feeder is replaced with buncher, can controls two rotating speed of motor, reach the purpose of automatic control burner output heat energy according to boiler pressure or boiler leaving water temperature.
