Abstract
The utility model provides a burner for a bell type annealing furnace, which is mainly composed of a base, an air pipeline, a gas pipeline, a cyclone and a burning chamber, wherein, the cyclone and the burning chamber are cast by high temperature alloy. The circumference of a gas jet hole A of the cyclone is provided with a plurality of air vortex seams C which form alpha angles with a shaft line of the cyclone, and a plurality of air dividing holes E which are parallel with the shaft line of the cyclone. The edge of the cyclone is provided with a plurality of rib pieces, and a circular seam B is formed between the edge of the cyclone and the inner wall of the burning chamber. The utility model has the advantages of sufficient mixing of the gas and the air, complete burning, high heat efficiency, convenient installation and operation, long service life, etc.
Description
The utility model relates to the burner that a kind of combustion gas heat-treatment furnace is used, especially a kind of bell-type annealing burner.
At present, the bell-type annealing burner mainly is made up of base, air duct, gas pipeline, cyclone and combustion chamber, wherein cyclone adopts the corrosion resistant plate punching press to be welded mostly, not only size, shape are difficult to reach designing requirement, and under hot conditions, use the damage that also deforms easily, the service life of having reduced burner for a long time; Structurally the hybrid mode that air and combustion gas are adopted is more single again, or is spiral-flow type, or is shunting, makes the efficiency of combustion of combustion gas can not get improving, and has both influenced the thermal effectiveness of flat cold-rolled sheet, has wasted fuel again.In addition, because the combustion chamber is to adopt refractory material to make, compare all differently on material and manufacture craft with cyclone, both situations that just can occur not conforming to unavoidably on dimensional accuracy have also brought some inconvenience for the integral installation of burner like this.
The purpose of this utility model is to provide a kind of bell-type annealing burner that the multiple hybrid mode of air and combustion gas is rolled into one, so as to reach air, coal gas mixes abundant thermal efficiency height, the burner integral installation is convenient, the purpose of long service life.
Another purpose of the present utility model is to provide a kind of bell-type annealing burner of igniting automatically of being convenient to.
The purpose of this utility model is to realize like this, a kind of bell-type annealing burner mainly is made up of base, air duct, gas pipeline, cyclone and combustion chamber, wherein cyclone and combustion chamber are to be formed by the high temperature alloy casting, around the gas jet orifice A of cyclone, have several air swirls that become the α angle with the axis of cyclone and stitch C, and the air tap hole E parallel with the axis of cyclone, and the edge at cyclone has several muscle sheets, makes the edge of cyclone form annulus B between the inwall of combustion chamber.
This reality is novel installs an igniter in air duct, have a fire hole D in the side of cyclone and with the corresponding position of igniter simultaneously.
The utility model is owing to the pith that will influence air, gas flow, flow velocity and direction all concentrates on the cyclone by adopting high temperature alloy cast-in-block mode, not only make the precision height, integral installation is convenient, and have air, combustion gas mixing is abundant, thermal efficiency height, heat-resisting ability is strong, advantages such as long service life.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a front view of the present utility model;
Fig. 2 is the front view of cyclone in the utility model;
Fig. 3 is the vertical view of Fig. 2;
Fig. 4 is the B-B cutaway view of Fig. 3.
As shown in Figure 1, bell-type annealing burner of the present utility model, mainly formed by base 5, air duct 2, gas pipeline 3, cyclone 1 and combustion chamber 6, wherein cyclone 1 and combustion chamber 6 are to be formed by the high temperature alloy casting, having several axis with cyclone 1 around the gas jet orifice A of cyclone 1 becomes the air swirl at α angle to stitch C, and the airport E parallel with the axis of cyclone 1, and the edge at cyclone 1 has several muscle sheets 11, makes the edge of cyclone 1 form annulus B between the inwall of combustion chamber 6.The quantity of air swirl seam C is 10-18, with between the parallel air tap hole E apart from one another by distribution.Shown in Fig. 2,3,4, combustion gas is by the oblique ejection of fuel gas hole A, and the angle of gas jet orifice A axis and cyclone 1 axis is β=30-60 °, combustion gas is divided into the multithread thigh sprays at a certain angle, has increased combustion gas and Air mixing area, accelerates burning.Air divides three parts by cyclone 1 ejection, and a part makes it form swirling eddy by eddy flow seam C ejection, increases the mixing intensity with combustion gas, plays the effect of the retention flame simultaneously; A part makes air form many threads thigh by parallel split-flow hole E ejection, improves the axial velocity of air-flow, has increased the contact area with combustion gas, promotes conflagration; Sub-fraction is air film ring B ejection by the circumferential weld between cyclone 1 and the combustion chamber 6 in addition, and it is more abundant that air and combustion gas mixing are got, and improved burning velocity, has the cooling combustion locular wall simultaneously, the effect that increases the service life.Eddy flow stitches C center line and cyclone axis angle α=35-65 °, through the air spiral ejection of eddy flow seam C.Axis or the coincidence parallel with the axis of cyclone 1 of parallel split-flow hole E and air film seam B makes the abundant mixed combustion of combustion gas and air, and heat sent combustion chamber 6.
As shown in Figure 1, the utility model is installed an igniter 4 in air duct 2, has a fire hole D in the side of cyclone 1 and with igniter 4 corresponding positions simultaneously, has automatic igniting convenience, reliable characteristics.
