Abstract
The utility model relates to a flame-tube type oil burner for the industrial furnace, which is composed of a flame tube, an outer shell, an oil nozzle, etc. The utility model is characterized in that the combustion-supporting air entering the flame tube has two flowing directions, and the combustion-supporting air enters the flame tube from a plurality of parts according to a definite proportion, thus the oil fuel is guaranteed to be sufficiently vaporized and mixed, the effect of the sufficient combustion is reached, the tube wall of the flame tube is effectively protected, and the flame tube forms no coke and does not exceed the temperature. The utility model has the advantages of simple structure, simple manufacturing technique, low requirement on the material quality, easy ignition, fast temperature increase, high combustion effect (the combustion effect reaches 99.5%), little pollution, low noise, etc., and is suitable for combusting various kinds of gas fuel and coal fines.
Description
The utility model relates to continuous internal combustion flame burner.
Chinese patent (CN85200213) discloses a kind of used for industrial furnace fuel oil burner, its combustion air mainly on the annular space from the burner inner liner and the flame tube plate institute's perforate enter in the burner inner liner, because the distribution of air-flow is not an optimal proportion, and also there is weak point on the flow direction, therefore, often there is Mars to occur in this burner burner hearth, especially in external condition (oil temperature, oil pressure, blast) when not satisfying specification requirement, Mars is more, causes burning insufficient.In addition, slight little coking phenomenon is arranged on burner inner liner, the air-flow protection measure is capable inadequately.
The purpose of this utility model is exactly to overcome the shortcoming that existing burner exists, and provides a kind of manufacturing process simple, easy for installation; air flow direction is reasonable; it is appropriate respectively to flow to the gas dosage, makes air can finish the vaporization of mist of oil and fully burning, can protect the burner of burner inner liner again reliably.
Burner of the present utility model has been done rational selection on distribution amount and air flow direction scheme.Air divides two kinds to flow to a plurality of positions and enter burner inner liner by a certain percentage.A kind of be the bottom direct-axis of burner inner liner to spraying into, its air inflow accounts for 3%～15% of total air inflow; Second kind is to be nested from adjacent two cylinders of burner inner liner that direct-axis is to spraying into along the burner inner liner internal face the annulus space that poststack constituted, and its air inflow accounts for 60～85% of total air inflow; Radially spray into the third hole that is from flame tube wall to be bored, its air inflow is 20～40% of total air inflow.
In the utility model, owing to strengthened the footpath aweather, thus strengthened the backflow of flame, the temperature of vaporizing zone is increased, the axial velocity of vaporizing zone " air-flow " lowers to some extent, and the burning of mist of oil is more abundant.Simultaneously, because the distribution of axial flow amount adjusts, and burner inner liner annular space air inlet place set up guide frame, makes gas more favourable to the autoprotection of burner inner liner, avoided coking phenomenon.The utility model is also simplifying manufacturing process, and some structural improvement have been done in the convenient installation aspect of using.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the schematic diagram of expression burner inner liner welding manner;
Fig. 3 is the expanded view of Fig. 2.
Fig. 1 has provided an embodiment of the present utility model.The utility model mainly is made up of burner inner liner, shell (3), end plate (8), atomizer (10), injector sleeve (12), inner flange (1), inlet scoop (5), igniter plug (9) etc. as shown in the figure.Burner inner liner is formed by the unequal cylinder of a plurality of diameters (4) phase intussusception, adjacent two cylinder intussusception length L are 15～25 millimeters, each cylinder inner surface is intussusception length L ' be 30～50 millimeters not, the drum diameter that has annular space (tube inside radius and little tube outer radius is poor greatly) to form burner inner liner between adjacent two cylinders increases flare from oil inlet end gradually to the flame end, and the annular space between adjacent two cylinders also increases to the flame end gradually from oil inlet end.Have inner groove (20) on the described injector sleeve (13), and have the radial hole (18) of linking up described inner groove (20) and burner housing inner chamber, atomizer and injector sleeve have annular space e between (12).On described flame tube plate (13), have 1～4 annulate shaft to aperture (17).Burner inner liner near the cylinder of flame tube plate (13) near the base plate place have one the ring radial hole (19), on 1～3 pitch circle tube of burner inner liner flame end, respectively have a ring radial hole (15), and cylinder the closer to the flame end, open on it that radially the aperture is big more, spacing is big more between the Kong Yukong.
If the radial hole area summation of being opened on annular space area summation+flame tube wall between two cylinders on the air inlet gross area of the present utility model=(the axial aperture area of opening on the annular space area+flame tube plate (13) between atomizer and the injector sleeve)+burner inner liner.Then on 3～15% burner inner liners that the axial aperture area sum of opening accounts for the air inlet gross area on annular space area between atomizer and the injector sleeve and the flame tube plate (13) mutually between two cylinders of intussusception annular space area summation account for 60～85% of total air inlet area, open radial hole area summation on the flame tube wall and account for 20～40% of total air inlet area
In the utility model, in order to reduce the air intake resistance, there is an air intake guiding circular arc (16) in the annular space import department on every pitch circle tube of burner inner liner.As shown in Figure 1, inlet scoop in the utility model (5) has a hypotenuse with air guide flame end, and the burner inner liner center line overlaps with outer casing centerline.
Shown in Fig. 2,3, each cylinder of burner inner liner of the present utility model adopts the some rivet welding to connect, and promptly on the circumference of outer cylinder one end that is nested, contacts with the inner cylinder that matches towards a plurality of grooves (21), and make it and the inner cylinder solid welding, and open a corresponding air inlet compensate opening (22) at each groove.
As shown in Figure 1, igniter plug (9) is loaded on the oil spout end of burner inner liner in the utility model by the hole of being opened on the hole of being opened on the Shell Plate (8) and the flame tube plate (13).Injector sleeve (12) is welded in the medium pore of flame tube plate, and places the medium pore of end plate of outer cover (8), by circular nut (11) burner inner liner and shell is fixed.In the utility model, inner flange (1) plays supporting and connects burner inner liner and shell, and this flange can move axially.In order to be suitable for different furnace chamber installation requirements, the utility model has also disposed tube outer loose flange (2).In addition, disposing one on the inlet scoop can be for the inlet scoop flange (6) that usefulness is installed.In the utility model, burner inner liner shell (3), inlet scoop all available common iron or corrosion resistant plate manufacturings such as (5).
Make model machine according to the utility model, reach following effect through on probation: when charge oil pressure at 1MPa, heavy oil temperature is about 130 ℃, blast is when 300 millimeter of water, the black furnace igniting emits little cigarette time no longer than 5 seconds; Namely enter normal combustion, rear is smokeless, no oil droplet, and efficiency of combustion reaches 99.5%, and flame temperature can be adjusted between 1000 ℃～1300 ℃, and skin temperature is not super Cross 150 ℃, the burner inner liner temperature is no more than 600 ℃.
