The invention relates to two channel injector energy saving burner. Its features are that it combines tangential injector with venturi one; eddy flow cylinder is set in the mixing chamber. Thus the invention can form turbulent flame with great combustion intensity under the action of two stage injector and eddy flow cylinder without blower. It can combine the advantages of diffusion combustion and premixed combustion, improve the mixture of flue gas and air, reduce heat dissipation, increase flame temperature, and reduce the discharge of the nitric oxides and carbon monoxide.
Description
Technical field
The present invention relates to a kind of fuel gas buring equipment, particularly a kind of small-sized fully-premixed gas burner belongs to the combustion apparatus technical field.
Background technology
The burner that uses in the present existing technology mostly is air blast burner, its air blast not only produces noise, consume a certain amount of electric energy, and the excess air in when burning is more, increased radiation loss, reduced the thermal efficiency of burner, the more combustion flame temperature not high (being about 900 ℃) that also can cause of excess air.
Summary of the invention
The purpose of this invention is to provide a kind of double passage ejection energy-saving burner, make this burner under the situation that does not dispose pressure fan, by the double passage ejection technology, enough air capacities can be provided, thereby reach the reduction radiation loss, improve flame temperature, reduce noise and save the investment of pressure fan and the purpose of operating cost.
Technical scheme of the present invention is as follows:
A kind of double passage ejection energy-saving burner, the venturi injector that contains gas-air mixing chamber, combustion chamber and be arranged on the mixing chamber bottom, the outlet of described venturi injector extend into mixing chamber inside, it is characterized in that: tangential injector is set in the side of gas-air mixing chamber, the whirlwind tube of band expanding section is set in this mixing chamber, on described cyclone wall, is provided with flow deflector.
The height H of gas-air mixing chamber of the present invention
2Be 90～120mm, outlet diameter D
2Be 100～130mm, the whirl cylinder diameter D that it is inner
3Be 70～100mm, height H
3Be 50～80mm.
Technical characterictic of the present invention also is: the angle β of flow deflector on the described whirl cylinder and barrel circumference is 30～60 degree.
On the basis of technique scheme, venturi injector outlet diameter D of the present invention
4Be 70～100mm, insert the depth H of mixing chamber
5Be 40～60mm.The throat diameter D of described combustion chamber
1Be 100～120mm, tapering α is 5～10 degree, and the degree of depth is H
190～120mm.
The present invention compared with prior art, have the following advantages and the high-lighting effect: 1. the present invention is owing to increased tangential injector, itself and venturi injector make up, and the air capacity of injection is higher than single-stage venturi injection, can form to have the very turbulent flame of high combustion intensity.Under the situation that pressure fan is not installed, this burner can provide enough air capacities, has reduced the excess air coefficient of burner, has saved the investment and the operating cost of pressure fan, has reduced noise, has guaranteed the high efficiency of burning.The air of 2. tangential injection enters whirl cylinder, under the effect of flow deflector, makes the air-flow rotation, and and the combustion gas-air mixture of venturi injector injection in mixing chamber, mix flame combustion temperature height, no tempering, not over-emitting black exhaust fully.3. the combustion chamber is made by nonmetal high temperature resistant heat storage material, combustion gas-air mixture to full premix carries out sufficient preheating, it is taken fire when arriving combustion chamber throat, the major part of flame in the cone space of the combustion chamber first half, a large amount of heat loss through radiation when having avoided the open type diffusion combustion.Flame temperature is very high, and the heat loss through radiation amount is less, so efficiency of combustion is higher.This burner has improved about 20% than the thermal efficiency of normal burner, and central temperature is brought up to more than 1000 ℃.4. nitrogen oxide and carbon monoxide emission have been reduced.The present invention is because its unique secondary injection, eddy flow mixing and secondary wind preheating technology, improve combustion gas and Air mixing situation, reduced excess air coefficient, reduced radiation loss, improved flame temperature, the nitrogen oxide of burner and the discharge capacity of carbon monoxide are reduced.

The specific embodiment
Further specify concrete structure of the present invention and preferred forms below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of double passage ejection energy-saving burner embodiment provided by the invention, and this burner contains venturi injector 1, gas-air mixing chamber 2, combustion chamber 3, the whirl cylinder 5 of tangential injector 4 and band expanding section; Described venturi injector is arranged on the bottom of mixing chamber, and axial arranged, is used to provide partly-premixed air; Venturi injector outlet diameter D
4Be 70～100mm, stretch into the depth H in the mixing chamber
5Be 40～60mm.Tangential injector 4 is arranged in the side of gas-air mixing chamber, and remaining premix air is provided, and generally adopts the structure of 2 symmetric arrangement; Because the negative pressure that internal-external temperature difference produces, the air that tangential injection is advanced mixes fully with the axial flow that certain included angle and venturi injector injection advance.Whirlwind tube 5 is arranged in the mixing chamber, comprises facade and conical surface two parts, and its barrel is provided with the flow deflector of evenly arranging vertically 6, and this whirlwind tube and venturi injector are arranged on the same center line.Whirl cylinder diameter D
3Be 70～100mm, height H
3Be 50～80mm.The angle β of flow deflector on the described whirl cylinder and barrel circumference is 30～60 degree.Owing to increased tangential injector 4 and in mixing chamber, increased flow deflector 6 on whirl cylinder 5 and the whirl cylinder, formed the secondary injection mode of venturi injection and tangential injection, the injection air capacity is higher than single-stage venturi injection, and because the air rotation that the whirl cylinder in the mixing chamber advances tangential injection makes combustion gas and Air mixing more abundant; And the air that tangential injection advances can also play the effect of preheated fuel gas-air mixture, cooling and mixing chamber, improved efficiency of combustion, makes this burner not use pressure fan also can provide enough power, and can prevent tempering.
Combustion gas and air enter combustion chamber 3, the height H of gas-air mixing chamber through air after fully mixed and the preheating in mixing chamber
2Be generally 90～120mm, outlet diameter D
2Be generally 100～130mm; The special refractory material of combustion chamber 3 liners, when burner operation, the temperature of refractory material raises rapidly, make follow-up combustion gas-air mixture reach ignition temperature when arriving the inner certain altitude in combustion chamber and take fire, and has avoided the radiation loss that burning produces in the open spaces externally.By experiment as can be known, the height of its combustion chamber of burner of different capacity is different with throat diameter.The throat diameter D of combustion chamber
1Be generally 100～120mm, tapering α is 5～10 degree, and the degree of depth is H
190～120mm.
