The biomass material of stalk class can generate a kind of liquid fuel, popular bio oil or the bio-oil of being called by the fast pyrogenation reaction.Present bio-oil can replace fossil liquid fuels such as heavy oil, crude oil and diesel oil as a kind of reproducible liquid fuel and be applied on boiler and the kiln.The fluid combustion device of Cun Zaiing is primarily aimed at that above-mentioned fossil fuel designs in the market, its atomizing type mainly comprises two kinds: 1, mechanical atomization, 2, medium atomization, and utilize the rapid evaporation characteristic of fossil liquid fuel and realize the burning of oil droplet.Because the bio-oil calorific value is at 15～18MJ/kg, moisture is near 25%, and contains a lot of macromolecular organic matters, belongs to the liquid fuel that calorific value is on the low side, viscosity is bigger than normal, is not easy to realize combustion by evaporation fast.In sum, directly utilize burner now, it is bad surely to fire effect, and bio-oil can not be realized completing combustion and cause oil gun nozzle, steady combustion dish and furnace chamber that coking phenomenon easily takes place, and causes environmental pollution big, and bio-oil can not normally be used.
The utility model content:
Technical problem to be solved in the utility model is: the deficiency that is intended to overcome above-mentioned existing liquid-fuel burner, select the good air dielectric atomizing oil atomizer gun of a kind of atomizing effect for use, appropriate design is surely fired wind and secondary wind, make the oil gun exit form a steady combustion zone, after the bio-oil oil droplet that atomizing is good passes through steady combustion district, the time of staying increases and realizes its gasification, contacts rapidly with secondary wind and realizes fast and completing combustion.
The utility model technical scheme:
A kind of bio-oil burner, concrete structure is the inlet that atomized oil gun one end of internal-mixing has pressure-air and bio-oil, the other end stretches in the burner of tubular, be linked with blower inlet on the barrel of burner, steady combustion dish is installed in the burner, described steady combustion dish is made up of inner cylinder, outer cylinder and the flow deflector that is installed between inner cylinder, the outer cylinder, described inner cylinder is set in outside the atomized oil gun, outer cylinder is enclosed within the front end of inner cylinder, forms annular chamber between described outer cylinder and the burner barrel.
Described each flow deflector is intervally arranged and staggers superimposed in adjacent flow deflector top mutually.
The length that described flow deflector is superimposed with each other is greater than 10mm.
Described atomized oil gun atomized spray angle is less than 50 °.
The utility model selects for use pressure-air as atomizing medium, the high-pressure air pressure scope is at 0.2～0.5Mpa, bio-oil oil pressure scope: 0.3～0.6Mpa, bio-oil and pressure-air enter interior realization of atomized oil gun of described internal-mixing fully to be mixed, by the ejection of rifle mouth, bio-oil (Kg/h) and atomizing air (m
3/ h) in (5-7): 1 ratio proportioning; Air blast provides the burning air distribution, enters in the tubular burner air quantity (m of air blast
3/ h) ratio with bio-oil oil mass (Kg/h) is (5-10): 1, the air blast air intake is split into secondary wind and steady combustion wind after entering the tubular burner, secondary wind sprays from described annular chamber, described steady combustion wind is from ejection between the flow deflector and form swirling eddy, and the flow proportional of secondary wind and steady combustion wind is 1: (1-2).
Bio-oil burner of the present utility model, select the internal-mixing atomized oil gun for use, and appropriate design surely combustion dish and secondary wind structure, make steady combustion dish exit form the steady combustion district of a strong flame, the bio-oil oil droplet is in steady combustion district's rotation, increase the time of bio-oil oil droplet evaporation gasification, and realized bio-oil to stablize and burning fully.The burner that adopts this structure has extraordinary combustion efficiency to the liquid fuel of low heat value, easily coking, and this burner structure is simple, convenient disassembly, realize control automatically easily, be to promote this low heat value of bio-oil, substitute the fossil liquid fuel and have great importance but have liquid fuel renewable, environment protection significance.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of steady combustion dish of the present utility model.
The specific embodiment:
Referring to Fig. 1,2.A kind of bio-oil burner, atomized oil gun 1 one ends of internal-mixing have the inlet of pressure-air 2 and bio-oil 3, the other end stretches in the burner 4 of tubular, be linked with blower inlet 5 on the barrel of burner 4, steady combustion dish 6 is installed in the burner 4, described steady combustion dish 6 is made up of inner cylinder 7, outer cylinder 8 and the flow deflector 9 that is installed between inner cylinder 7, the outer cylinder 8, described inner cylinder 7 is set in outside the atomized oil gun 1, outer cylinder 8 is enclosed within the front end of inner cylinder 7, forms annular chamber 10 between outer cylinder 8 and burner 4 barrels.Each flow deflector 9 is intervally arranged and staggers superimposedly in adjacent flow deflector 9 tops mutually, and the length that is superimposed with each other is greater than 10mm.Atomized oil gun 1 atomized spray angle＜50 °.
As shown in Figure 1, utilize the bio-oil burner to carry out the method for bio-oil burning, select for use pressure-air as atomizing medium, the high-pressure air pressure scope is at 0.2～0.5Mpa, bio-oil oil pressure scope: 0.3～0.6Mpa, bio-oil and pressure-air enter interior realization of atomized oil gun of described internal-mixing fully to be mixed, by the ejection of rifle mouth, bio-oil (Kg/h) and atomizing air (m
