The specific embodiment
Existing heat resisting cast steel burner made is because being subject to the restriction of its material and processing method, must be divided into burner body and burner nozzle, but owing to connecting the thermal deformation repeatedly of the flange surface of burner body and burner nozzle, will produce the distortion of flange part, or, produce sealing deteriorated, cut off the fuel gas causing, the leakage of combustion air.The inventor etc. concentrate on studies, found that, by changing burner into stainless steel that burner body and burner nozzle are become one structure by the partitioning scheme of heat-resistant cast steel, even if can provide, repeatedly carrying out continually, under the environment for use of operation-stop, also thering is the igniter of thermal stress.
Table 1 is the result that the effect of material change is compared.Due to the material of burner is changed to the stainless steel that burner body and burner nozzle are structure as a whole by heat resisting cast steel, can not produce the fuel leakage that the distortion by flange part causes.And, by by the wall thickness reduction of burner, nozzle, alleviated the distortion of residual stress and burner.Consequently, even if form, repeatedly carrying out continually under the environment for use of operation-stop the burner that also can use for a long time.
[table 1]
And then the angle that the discharging jet of fuel gas and combustion air is crossed is mutually studied, found that, by being below 60 degree by this angle initialization, can reduce the temperature of spray nozzle part, there is the effect that prevents that spray nozzle part from cracking.Below, by table 2 and Fig. 4, describe.
Table 2 is to test with the experiment burner that burner width is 500mm is set in combustion furnace, evaluates the result of durability.The opposite face of the burner in stove is laid iron plate, forms burner and accepts the photothermal structure from below.Iron plate temperature be with the equal 1300 ℃ of conditions of common sintering machine operation, with the condition of 1350 ℃ of the situation of supposition sintering machine operation change under, repeatedly heat up, the assigned temperature of 30 minutes keeps, cooling, to observe the damage status of burner.
By burner is changed into the welded structure of thinner stainless-steel sheet by the segmenting structure of existing heat-resistant cast steel, thermal deformation disappears.In common sintering machine operation, raw materials for sintering layer surface temperature (the interior temperature of stove while being equivalent to test) is 1300 ℃, in common job area, can prevent that crackle from producing by burner material being set as to stainless steel.Known, even the change due to sintering machine operation, make temperature in stove rise to 1350 ℃, also can be by the angle that the discharging jet of fuel gas and combustion air crosses be mutually crossed to the acute angle of 60 degree, 40 degree from 90 previous degree, thereby reduce spray nozzle part temperature, thus, can reduce the crackle frequency of spray nozzle part.As shown in table 2, with respect to testing under 90 degree 3 times, crack, while being 6 times under 60 degree, crack, while being 10 times under 40 degree, crack, durability improves.Finding, is below 60 degree by the angle initialization that the discharging jet of fuel gas and combustion air is crossed mutually, can reduce the temperature of spray nozzle part, so have the effect that prevents that spray nozzle part from cracking.
[table 2]
Fig. 4 represents apart from the distance of burner nozzle and the relation of flame temperature.Along with the angle initialization that the discharging jet of fuel gas and combustion air is crossed is mutually acute angle, temperature is that 1300 ℃ of above flame parts are elongated, must lengthen the distance between burner and heating surface.If the angle that discharging jet crosses is mutually the scope of 30 degree～60 degree, the temperature till from burner nozzle to 100mm can significantly decline, and therefore, is suitable for reducing spray nozzle part temperature, prevents that spray nozzle part from cracking.
If the angle deficiency mutually crossing of discharging jet 30 degree, burner flame length grows to over 850mm, causes burner hood to maximize, and energy loss increases, and is not therefore preferred version.
Preferably, the burner that stainless steel Plate Welding processing is made of the present invention is arranged a plurality of uses on the width of sintering machine.By arrange a plurality of burners on width, Temperature Distribution in the time of can be with reference to operation, the burning condition of sintering machine width is carried out other change, adjusted, even if there is the operating conditions such as distribution change of raw material layer thickness, change, also can adjust the Temperature Distribution on width.
In the present invention, preferably, thermal expansion is set between a plurality of burners and absorbs surplus.As long as the size of thermal expansion surplus is provided in the interior temperature atmosphere of ignition furnace in operation, the end of the burner of adjacency is close to because of thermal expansion,, in operation, can not occur to attract ambient air from this expansion space, make the situation of ignition flame confusion reigned.
In addition, burner uses stainless-steel sheet and thin-walled property, thereby makes burner lightweight, therefore, can simplify burner supporting structure, and engineering is set also becomes easy.
Below, one embodiment of the present invention is described.
In Fig. 2, a part for sintering machine supporting plate and igniter is expressed as to section.Bb represents burner body, and Bt represents burner termination, and F represents flame, and L represents the distance from burner front end to raw materials for sintering layer surface.Fuel gas supply pipe 8 and air supply pipe 9 are arranged on the width integral body of supporting plate, possess a plurality of burners of fuel gas pipe 6 and combustion air pipe 7 with the gap arrangement of thermal expansion surplus, be configured to and fuel gas supply pipe 8 and air supply pipe 9 almost parallels.Flue 6 and gas supply pipe 8 are connected via short tube 10, and in addition, air hose 7 and air supply pipe 9 are connected via short tube 11.Fuel gas supply pipe 8 and air supply pipe 9 are supported by beam 26.
