Abstract
The utility model relates to a burner, the structure of which is that the circumference of a spray head at the front end of a casing is provided with a plurality of tangential oil gas spray holes with different rotary angles, the middle part of the spray head is provided with a flow dividing cone and an atomizing chamber in the casing is communicated with an oil gas spraying hole. An oil gas assembly is arranged at the back end of the casing, and a rotary flow accelerator is arranged in an oil inlet hole which is arranged on the oil gas assembly. A plurality of flow guiding oil holes which are arranged in a tangential way are arranged on the rotary flow accelerator. The circumference of the oil gas assembly is provided with a plurality of tangential air inlet holes with different rotary angles. Oil spray holes are positioned at the middle position of the oil gas assembly, and are communicated with flow guiding oil holes. The utility model has the advantages that the rotary flow accelerator causes fuels to be changed into fog by the low pressure from 0.05 MPa to 0.08 MPa, the fog and the airflow at the air inlet holes of the oil gas assembly are mixed to form a vaporized shape, different requirements for the burning capacity can all be satisfied under the condition of lower pressure, the burning capacity can reach 50 to 2000 kg/h, the stable burning can be realized under the condition of hypoxia, the fume exhaust temperature is lowered, the heat efficiency is improved, and the burning for various fuels can be switched to realize the single burning and the mixing burning for oil, gas and coal water slurry. The utility model has the characteristics of environment protection, energy saving and high safety.
Description
Technical field
The utility model relates to a kind of burner that is applied to fields such as thermal power plant, oil, chemical industry, metallurgy and industrial boiler, heating furnace, ceramic stove, heating.
Background technology
Similar products at home and abroad generally adopts mechanical atomization at present, and the form of using high pressure 1.5-4.0Mpa reduces the purpose that viscosity reaches atomizing to improve fuel oil temperature.The shortcoming of its existence is: because the charge oil pressure height brings unsafe factor to oil pipeline, improve temperature, waste energy, increase equipment investment; It is the both vapor compression air atomizing that a kind of form is arranged again, and fuel nozzle is that the form of utilizing airflow strikes to shear oil stream realizes atomizing mostly in the market, and this kind mode air consumption is big, and working pressure is higher, generally all in the 0.6-1.5Mpa scope.More than several atomised forms all ubiquity phenomenons such as cold conditions is difficult for lighting, over-emitting black exhaust, coking, obstruction, be subjected to the influence of system pressure fluctuation easily to cause fire-putting-out emergency, oil can be gone here and there and be gone in the tracheae when oil pressure is higher than air pressure, meeting oil sealing when air pressure is higher than oil pressure, cause fire-putting-out emergency, single mouth burning capacity is restricted (can not finish high-power burning).Combustion instability.
Summary of the invention
The purpose of this utility model is a kind of multifunctional low-voltage classification eddy flow burner that provides for the problem that solves the prior art existence.
Multifunctional low-voltage classification eddy flow burner is characterized in that: housing 5 front ends are provided with shower nozzle 1, and the shower nozzle circumference is provided with the tangential oil-gas jetting hole 3 that several anglecs of rotation do not wait, and the shower nozzle middle part is provided with branch flow cone 2, also is provided with oil gas squit hole 4 on the shower nozzle; Be provided with the spray chamber 6 of Lavalle shape in the housing, spray chamber 6 communicates with oil gas squit hole 4; Oil gas assembly 11 is contained in housing 5 rear ends, on the oil gas assembly, be provided with eddy flow accelerator 12 in the fuel feed hole, on eddy flow accelerator 12, be provided with the water conservancy diversion oilhole 14 of several arranged tangential, water conservancy diversion oilhole 14 communicates with fuel feed hole 13, is provided with the tangential admission hole 10 that several anglecs of rotation do not wait on oil gas assembly circumference; Nozzle opening 7 is positioned at oil gas assembly centre position for having the spray orifice of the angle of flare, communicates with water conservancy diversion oilhole 14; Be provided with the six side's plate mouth 8 and the binding threads 9 that this device can be fixed on the multi-form burner in the housing rear end.
The utility model has the advantages that: it has changed traditional atomization method, and working pressure is low, is 0.05-0.8MPa, all can satisfy the needs of different burning capacitys under lower pressure condition, and burning capacity can reach 50-2000Kg/h.Because atomization is good, excess air coefficient is low, air coefficient is less than 1.05, can realize smooth combustion under the hypoxia condition, reduce exhaust gas temperature, improve the thermal efficiency, reduce the growing amount, the discharge capacity that reduce harmful substance in the combustion process, especially fuel is easily lighted under cold conditions-10 ℃ condition, no black smoke, safety, environmental protection, energy-conservation multiple effect have been played in stifled noncoking.The utility model can switch single fire and the multifuel combustion that the various different fuels of burning are realized oil, gas, water-coal-slurry.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Operation principle of the present utility model is: fuel is through fuel feed hole 13, water conservancy diversion oilhole 14, the eddy flow accelerator 12 of flowing through, it is vaporific that fuel is formed, various atomizing medium (the compressed air that enter with air admission hole 10 from oil gas assembly 11 circumference, steam, combustion gas, air blast etc.) phase blending, form rotation at a high speed in the spray chamber 6 in housing 5 through oil gas squit hole 4, the oil-gas jetting hole 3 rotation ejections of arranged tangential on the shower nozzle 1, under the effect of minute flow cone 1, form uniform distribution field by required different jet angle, make the proportioning of fuel and gas more reasonable through blending in many ways, improve burning velocity.
