Detailed description of the invention
Existing heat resisting cast steel burner is because being limited by its material and processing method, it is necessary to be divided into combustion
Burner main body and burner nozzle, but owing to connecting the anti-of the flange surface of burner body and burner nozzle
Re-heat deforms, it will produce the deformation of flange part, or, the deterioration of generation sealing, cut-out cause
Fuel gas, the leakage of combustion air.The present inventor etc. are concentrated on studies, it was found that pass through
Change into making burner body and burner nozzle be integrally forming by the partitioning scheme of heat-resistant cast steel by burner
The stainless steel of structure, using the teaching of the invention it is possible to provide even if under the use environment that operation-stopping is repeated continually,
Also there is the igniter of thermal stress.
Table 1 is the result effect that material changes compared.Due to by the material of burner by heat-resisting
The rustless steel that cast steel is changed to burner body and burner nozzle is structure as a whole, will not produce by flange
The fuel leakage that the deformation in portion causes.And, by by burner, the wall thickness reduction of nozzle, alleviating
Residual stress and the deformation of burner.Even if operation-stop being repeated continually as a result of which it is, formed
Under use environment only, it is also possible to the long-time burner used.
[table 1]
And then, the angle mutually crossed the discharging jet of fuel gas and combustion air is studied,
It was found that by being less than 60 degree by this angle initialization, it is possible to reduce the temperature of spray nozzle part, have anti-
The effect that only spray nozzle part cracks.Hereinafter, illustrated by table 2 and Fig. 4.
Table 2 is to arrange the experimental combustion device that burner width is 500mm in experiment combustion furnace, evaluates
The result of durability.The opposite face of the burner in stove lays iron plate, formed burner accept under
The photothermal structure of side.Iron plate temperature be the 1300 DEG C conditions equal with common sintering machine operation,
Under conditions of suppose 1350 DEG C of situation of sintering machine operation variation, be repeated intensification, 30 minutes
Assigned temperature keeps, cooling, to observe the damage status of burner.
By being changed burner into relatively thin stainless-steel sheet by the segmenting structure of existing heat-resistant cast steel
Welded structure, thermal deformation disappears.In common sintering machine operation, raw materials for sintering layer surface temperature
(being equivalent to in-furnace temperature during test) is 1300 DEG C, in common job area, it is possible to by burning
Equipment matter is set as that rustless steel prevents crackle from producing.Understand, even if due to the variation of sintering machine operation,
In-furnace temperature is made to rise to 1350 DEG C, it is also possible to by making the discharging jet phase of fuel gas and combustion air
The angle crossed mutually crosses to 60 degree, the acute angle of 40 degree from previous 90 degree, thus reduces spray nozzle part temperature
Degree, thereby, it is possible to reduce the crackle frequency of spray nozzle part.As shown in table 2, test relative under 90 degree
3 times and crack, be to crack when 6 times under 60 degree, when being 10 times under 40 degree produce split
Stricture of vagina, durability improves.I.e. find, by the discharging jet of fuel gas and combustion air is mutually crossed
Angle initialization be less than 60 degree, it is possible to reduce spray nozzle part temperature, prevent spray nozzle part from producing so having
The effect of crackle.
[table 2]
Fig. 4 represents the relation of the distance away from burner nozzle and flame temperature.Along with by fuel gas and combustion
The angle initialization that the discharging jet of burning air mutually crosses is acute angle, and temperature is the flame portion of more than 1300 DEG C
Divide elongated, it is necessary to lengthen the distance between burner and heating surface.If the angle that discharging jet mutually crosses is 3
0 degree～the scope of 60 degree, then from burner nozzle to 100mm till temperature can significantly decline, because of
This, be suitable for reducing spray nozzle part temperature, prevent spray nozzle part from cracking.
If the angle mutually crossed of discharging jet is less than 30 degree, then burner flame length grows to more than 850
Mm, causes burner hood to maximize, and energy loss increases, and is therefore not preferred scheme.
Preferably, the burner processing of stainless steel Plate Welding made of the present invention is at sintering machine
Multiple use is arranged on width.By arranging multiple burner in the direction of the width, it is possible to reference to making
Temperature Distribution during industry, carries out other change, an adjustment, i.e. to the burning condition of sintering machine width
