Description
Technical field
The utility model belongs to boiler manufacturing technology field, is a kind of biomass liquid fuel boiler-burner specifically.
Background technology
At present, in city, 10 tons of following coal-burning boiler capacity are little, and quantity is many, and smoke evacuation flue dust is large, and pernicious gas is many, is one of primary pollution source in city, is badly in need of eliminating.And existing oil burning boiler and burning gas boiler cost are higher, especially use cost is too high, makes user be difficult to accept.Therefore, oil burning boiler and gas fired-boiler are not easy spread.
The specific requirement that China's proposition in this year will " be accelerated the coal-burning boiler that renovates, implement coal-burning boiler energy-saving Environmental-protection comprehensive and promote engineering, eliminate 50,000 arcolas for 2014, eliminate backward boiler 200,000 steam ton to the end of the year 2015 ".Reducing under the background of consumption of coal proportion and superseded small scall coal-fired boiler, how by these small scall coal-fired boilers by the upgrading of technological innovation, making it to become can source clean, efficiently utilize heat resource equipment, this is the object that present patent application will reach.
Summary of the invention
The problems referred to above that the utility model exists for solving prior art, and a kind of biomass liquid fuel boiler-burner is provided, as the burner special of biomass liquid fuel or the outfit of light-hydrocarbon fuel boiler, pollute littlely, the thermal efficiency is high, and it is simple in structure, cost is low, is suitable for coal-fired boiler reform.
The purpose of this utility model is achieved through the following technical solutions:
A kind of biomass liquid fuel boiler-burner, comprise burner body, it is characterized in that, fixed leg in the middle of described burner body comprises and the protecting tube of overcoat form tool housing with dissection, 4 biomass liquid fuel carrier pipes are at least set vertically in the interlayer of described housing, at every biomass liquid fuel carrier pipe, overlap an air delivery pipe outward, between described biomass liquid fuel carrier pipe and air delivery pipe, form air delivery passage, the outlet of biomass liquid fuel carrier pipe one end is for directly sealing nozzle to porous; The outlet of described air delivery passage one end is the oblique porous sealing nozzle around biomass liquid fuel carrier pipe outlet periphery.
Improvement to technique scheme: the air flow of described oblique porous sealing nozzle ejection becomes cross-like with the flow direction of the described fuel directly spraying to porous sealing nozzle.
Further improvement to technique scheme: the inclined hole ejection flow direction of air and the angle of turbulent burner axis of described oblique porous sealing nozzle are 6-8 degree, the air of the inclined hole ejection of described oblique porous sealing nozzle is eddy flow with the fuel of the described straight straight hole ejection to porous sealing nozzle and mixes.
Further improvement to technique scheme: described protecting tube is metal circular tube, described fixed leg is metal solid cylinder, the dead in line of described protecting tube and fixed leg.
Further improvement to technique scheme: described biomass liquid fuel carrier pipe is metal circular tube, described air delivery pipe is metal circular tube, the dead in line of described biomass liquid fuel carrier pipe and air delivery pipe.
Further improvement to technique scheme: described air delivery pipe is fixed on described fixed leg.
Further improvement to technique scheme: described air delivery pipe is fixed on protecting tube madial wall.
The utility model advantage and good effect is compared with prior art:
Burner body of the present utility model is that coaxial solid inner tube and outer tube suit forms tool sleeve pipe with dissection, and 4 biomass liquid fuel carrier pipes are at least set in described interlayer, and the outlet of biomass liquid fuel carrier pipe is for directly sealing nozzle to porous; Described interlayer is airflow pipe, and airflow pipe exit is oblique porous sealing nozzle around biomass liquid fuel carrier pipe outlet periphery.The air flow of described oblique porous sealing nozzle ejection becomes cross-like with the flow direction of the described fuel directly spraying to porous sealing nozzle, and the air of oblique porous sealing nozzle ejection is eddy flow with the fuel directly spraying to porous sealing nozzle and mixes.Sufficient combustion, can further improve the thermal efficiency.
Accompanying drawing explanation
Fig. 1 is the cut-away view of a kind of biomass liquid fuel boiler-burner of the utility model;
Fig. 2 is the structural representation of a kind of biomass liquid fuel boiler-burner of the utility model exit end face.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1, Fig. 2, the embodiment of a kind of biomass liquid fuel boiler-burner of the utility model, fixed leg 4 in the middle of burner body comprises forms tool housing with dissection with the protecting tube of overcoat 1,4 biomass liquid fuel carrier pipes 3 are at least set vertically in the interlayer of described housing, outside every biomass liquid fuel carrier pipe 3, overlap an air delivery pipe 2, between described biomass liquid fuel carrier pipe 3 and air delivery pipe 2, form air delivery passage.
The outlet of biomass liquid fuel carrier pipe 2 one end to porous sealing nozzle 6, directly has some straight hole 6-1 for directly on porous sealing nozzle 6.Outlet in air delivery passage one end is the oblique porous sealing nozzle 5 around biomass liquid fuel carrier pipe 2 outlet peripheries, on the ring surface of oblique porous sealing nozzle 5, has the inclined hole 5-1 that forms angle with turbulent burner axis.
Particularly, the air flow of described oblique porous sealing nozzle 5 ejections becomes cross-like with the flow direction of the described fuel directly spraying to porous sealing nozzle 6.Be conducive to mix, improve efficiency of combustion.
Preferably, the inclined hole 5-1 ejection flow direction of air and the angle of turbulent burner axis of described oblique porous sealing nozzle 5 are 6-8 degree, and the air of the inclined hole 5-1 ejection of described oblique porous sealing nozzle 5 is eddy flow with the fuel of the described straight straight hole 6-1 ejection to porous sealing nozzle 6 and mixes.Can make fuel combustion abundant, further improve the thermal efficiency.
