Description
Technical field
The utility model relates to the special external combustion apparatus of biomass solid formed fuel of a kind of Industrial Boiler and stove, specifically a kind of Biomatter gasifying direct combustion burner.
Background technology
The external biomass burner used in existing Industrial Boiler and stove mostly is biomass semi-gasification combustor, adopt feed on side, blowing down First air is oxygen debt burning in combustor, and thermal-flame heats with spraying in boiler to burn away after Secondary Air mixing oxygenating at nozzle again.Have following weak point: 1, combustor furnace volume is little, and fuel tolerance is bad, its combustion temperature is higher, easy coking, use the high-quality Wooden Biomass fuel that ash is few, ash fusion point is high; 2, require higher to operating personnel, feed and primary and secondary air will coordinate appropriate guarantee combustor normal table to burn; 3, fuel blows floating burning in combustor, and a large amount of ashes enters burning spout and boiler with flame to the greatest extent, and make the easy coking of port, stove internal flue easily blocks; The whirlwind back-fire relief dedusting of the supporting complexity of the higher need of the initial smoke content of boiler export and bag pulse dedusting carry out process to flue gas can qualified discharge.
Utility model content
The purpose of this utility model is to provide a kind of efficiency of combustion high, fuel-saving Biomatter gasifying direct combustion burner, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of Biomatter gasifying direct combustion burner, comprise burner body, described burner body is configured with spiral feeder, and burner body upper end is provided with material-falling hopper, and the discharging opening of spiral feeder is positioned at above material-falling hopper; Burner body inside is provided with vaporizer, and the discharging opening of material-falling hopper is positioned at vaporizer top; Burner body side is provided with the blower fan that once gasifies, and the air outlet of the blower fan that once gasifies is positioned at vaporizer; Offer burning spout on the upside of burner body front end, burner body side is provided with overfire air fan again, and the air outlet of overfire air fan is positioned at burning spout-base, overfire air fan and burning spout connection.
As further program of the utility model: the described air outlet once gasifying blower fan is positioned at vaporizer bosom formation center on the lower side gasification structure.
Compared with prior art, the beneficial effects of the utility model are: the utility model is reasonable in design, and structure is simple, convenient operation and maintenance, and only need adjust first and second air quantity can regulate boiler load, and feed keeps material level automatically.Gasification temperature is 500 ~ 700 DEG C, can not coking in stove, and the larger herbaceous biomass fuel of ash also can gasification, and combustion, more can make full use of various biomass resource.Efficiency of combustion reaches more than 98%, and supporting horizontal internal combustion boiler, boiler overall thermal efficiency reaches more than 87%.The initial smoke content of boiler export is extremely low, adopts gasification direct-combustion sectional combustion mode, and ignition temperature is in 900 ~ 1000 DEG C, and effectively reduce the generation of nitrogen oxide, fume emission reaches the discharge standard of gas fired-boiler completely, more environmental protection.Adopt all-sealed structure, gasification i.e. burning, without Cemented filling, does not produce leakage, port can maintain enough ignition temperatures, there will not be flame-out situation, when blower fan stops, residual air can maintain low baking temperature burning until no longer produce fuel gas at port, safer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-spiral feeder, 2-material-falling hopper, 3-vaporizer, 4-once gasifies blower fan, 5-overfire air fan, and 6-burns spout.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of Biomatter gasifying direct combustion burner, comprises burner body, and described burner body is configured with spiral feeder 1, and burner body upper end is provided with material-falling hopper 2, and the discharging opening of spiral feeder 1 is positioned at above material-falling hopper 2; Burner body inside is provided with vaporizer 3, and the discharging opening of material-falling hopper 2 is positioned at vaporizer 3 top; Biomass solid formed fuel by spiral feeder 1 send into material-falling hopper 2 flow automatically again supplement drop down onto in vaporizer 3.Burner body side is provided with the blower fan 4 that once gasifies, and the air outlet of the blower fan 4 that once gasifies is positioned at vaporizer 3; Offer burning spout 6 on the upside of burner body front end, burner body side is provided with overfire air fan 5 again, and the air outlet of overfire air fan 5 is positioned at bottom burning spout 6, and overfire air fan 5 is communicated with burning spout 6.The blower fan 4 that once gasifies is sent into appropriate air fuel is gasified at internal cleavage in vaporizer 3, and the gasification burning of generation catches fire immediately at burning spout 6 place that burner outlet is special the Secondary Air mixed combustion produced with overfire air fan 5.
Because gasification air quantity is few, gasification wind speed is very low and will be filtered by the gap of biological plasmid in stove, therefore gasification burning is quite pure, and remaining a small amount of ash accumulates in the greatest extent burner base and regularly clears out and do not enter boiler with combustion gas, and the initial smoke content of boiler export is less than 30 milligrams of/cubic metre of flue gases.Efficiency of combustion is high, and biomass solid formed fuel fully gasifies and converts high-temperature combustible gas body in gasification combustor, and efficiency of combustion reaches more than 98%.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
