Description
Technical field
The present invention relates to a kind of punch forming metal burning device and manufacture method thereof that the fuel gas that is pre-mixed and Air mixing gas are supplied to burner port and make it to burn, form by the punch process metallic plate.
Background technology
In the past, as punch forming metal burning device, have a kind of by thin-wall metal plate punch process is become the warpage state, and formation has the flat fuel element (for example, opens flat 1-144616 communique or open flat 3-64314 communique in fact with reference to real) of gaseous mixture path and the combustion head that is connected with this gaseous mixture path.Wherein, be formed with the burner port of a plurality of slit pore shapes at the front end face of described combustion head.
In fact opening the disclosed technical characterictic of flat 1-144616 communique is: the front end face of combustion head is arranged to the chevron that is made of 2 inclined-planes, and forms the burner port of described slit pore shape on each inclined-plane.In addition, in fact open the disclosed technical characterictic of flat 3-64314 communique and be: be formed on the burner port of slit pore shape of the front end face of combustion head relatively, the position is provided with the cowling panel parallel with air-flow under it.
At this, in order to develop new punch forming metal burning device, imagination is at the real real cowling panel of opening flat 3-64314 communique of combustion head superordinate of opening the chevron of flat 1-144616 communique, and the real enhancing prismatic of opening flat 1-144616 communique of utilization becomes this cowling panel.For example, can form punch forming metal burning device shown in Fig. 6～Fig. 8 and Fig. 9 (a).In Fig. 6, the downstream (upper end side of Fig. 6) that is illustrated in the 210 gaseous mixture paths 240 that connect from the aperture forms the punch forming metal burning device of combustion head 230.The cross sectional shape of described combustion head also is to form the chevron that is made of the 1st inclined-plane 231 and the 2nd inclined-plane 232 as shown in Figure 7, and is formed with the burner port 261 of slit pore shape on each inclined-plane.That is, form the burner port face 250 of chevron.Symbol 30 expression decompression wall components among Fig. 8, this decompression wall components 30 is installed in the mode that coats its combustion head 230 from the outside for punch forming metal burning device as shown in Figure 6.On the combustion head 230 of such chevron, as shown in Figure 8 relatively the gaseous mixture of cowling panel 270 parallel supplies from two burner ports 261.261 of width (left and right directions of Fig. 8) both sides of chevron combustion head along the oblique ejection of left and right directions.Its result diffuses to form 2 independently internal flames 510,510 in both sides slightly to the left and right from each burner port shown in Fig. 9 (a), flame envelope 520 is comprising 2 and extending upward with some the state of swelling for the left and right directions width with flame.Promptly, flame envelope 520 is not to extend to the direction of advancing parallel with cowling panel merely, and extends upward with the state that expands along left and right directions with the result who contacts, the flame envelope 520 of auxiliary air by increase gaseous mixture from each burner port 261,261 along the oblique ejection gaseous mixture of left and right directions.
In addition, also consider to utilize the real enhancing prismatic of opening flat 1-144616 communique to become cowling panel, and combustion head is not made as chevron and is made as smooth shape, and form the burner port of 2 slit pore shapes for this smooth combustion head.That is, the burner port face is formed tabular surface.In this case, shown in Fig. 9 (b), independently internal flame 511,511 is along direction of advance (top) extension of the gaseous mixture that parallels with cowling panel 270 from 262,262,2 of each burner ports, and flame envelope 521 extends merely upward with the state that comprises these 2 internal flames 511,511.At this moment, the situation of the chevron of expansion ratio Fig. 9 of the root of flame envelope 521 (a) is little, and the width stenosis of the left and right directions of flame envelope 521 is narrow.
But, in the punch forming metal burning device of these schemes, following bad phenomenon is arranged.That is, this punch forming metal burning device is set at various combustion apparatus (for example, gas water heater), but along with the maximization of this combustion apparatus etc., pursue the wide combustion range of width.When burning with ceiling capacity, gas ejection flow velocity is further accelerated, its result will produce the problem of lifting (lifting) or oscillatory combustion, if burn with least energy, then produce the problem red or distortion of burning owing to flame is overheated.Especially in described two kinds of schemes, because 2 internal flames 510,510,511,511 contact at root, and separate, so the adhesion between 2 internal flames is tended to die down in front.Like this, even in any one of described two schemes, when keeping the wide wide combustion range of degree to change quantity combusted, existing condition such as gaseous mixture has change just can not keep the bad phenomenon of the flame instability of internal flame 510,510 slightly.And, if can not keep the mixing ratio of stable state, fuel gas and primary air temporarily to change the formation deviation, then easily produce the not phenomenon of the stable formation that can not keep flame that dispels.And, because the deviation of described mixing ratio, make described 2 internal flames, 510,510,511,511 mutual its retentivity variation of interference engagement, and cause the result of flame instabilityization, easily produce the bad phenomenon that whole burner forms the oscillatory combustion that resonance makes a noise.
And, also consider to append to be used for to remove and do one's utmost to reduce the countermeasures such as software of the generation usefulness of bad phenomenon, but the exploitation, installation etc. that must append new parts or software like this cause manufacturing cost to go up by the control burning at the special parts of the absorption vibration of these bad phenomenon or exploitation.
