Further, first impedor 33 with a plurality of through holes inserts and engages with an end 32a of first Road narrows 32.First impedor 33 is, stamped metal for example, ceramic post sintering metal or sintered metal net.In addition, the subject of mentioning here 20 is a kind of cylinders, for example for to have the burner flame tube 6 of zone of combustion or the transition piece 7 of its catchment, or is connected to by-pass pipe 11 on the sidewall, and is a kind of object of internal communication combustion vibration.

By above-mentioned structure, first casing 30 holds and the air of conduct in the fluid fine particle resonance of the vibration key element of the combustion vibration of the zone of combustion of burner flame tube 6 generation as the air vessel body.In addition, first Road narrows 32 are as connecting body, connecting object body 20 and first casing 30.In addition, first impedor passes the inside of first Road narrows 32 as weft element, and its through hole is as the outlet of the fluid fine particle of vibration with the air resonance of first casing, 30 inside.Like this, for the combustion vibration that the zone of combustion in burner flame tube 6 inside takes place,, can be caught by first impedor 33 effectively as the fluid fine particle of vibration key element by the propagation in subject 20; Therefore with first inner space 31 that links to each other by first Road narrows 32 in air resonate, and near first impedor 33, vibrate.By this vibration, the Oscillation Amplitude of suppression fluid particulate has reduced combustion vibration.Therefore, realize the stable minimizing of NOx.

In addition, among Fig. 1, one first Road narrows 32 are installed on first casing 30.Yet, much less, first Road narrows 32 more than two can be installed also.

Therefore, second embodiment of the present invention will be described with reference to Fig. 2.Second embodiment is characterised in that the special combustion vibration of considering first embodiment's medium and low frequency scope.When low-frequency range produces combustion vibration, need make according to the cross-section area in first embodiment's first Road narrows 32 to diminish.Yet, if do like this, to reduce the area at first impedor, 33 places inevitably, the capture rate that this just reduces fluid fine particle causes can not reducing combustion vibration fully on the whole.

Therefore, according to this embodiment, this stepped tubular body is as first Road narrows 32, and its inner circumferential promptly is stretched over the other end 32a from an end 32b near the center, and wherein the open area ratio the other end 32b of an end 32a is big.First impedor 33 inserts and engages with an end 32a.

Because like this, can make the inside of first Road narrows 32, just the cross section of the other end 32b diminishes, and simultaneously, the zone at first impedor, 33 places is enlarged, and increases the capture rate of the fluid fine particle of low-frequency range.Therefore, can reduce the combustion vibration of low-frequency range on the whole fully.

In addition, the horn-like object that enlarges gradually when inner circumferential can be obtained identical effect during as first Road narrows 32.

Secondly, with reference to Fig. 3 the third embodiment of the present invention will be described.The 3rd embodiment is characterised in that the reaction that produces among consideration second embodiment.As second embodiment, the open area ratio the other end 32b of one end 32a of first Road narrows 32 is big, just the volume when first Road narrows, 32 inside becomes big, each pressure surge between the space of space in first Road narrows 32 of being isolated by first impedor 33 and subject 20 does not produce sometimes and differs ("+" among the figure and "+").In this case, because fluid fine particle does not vibrate,,, can produce reaction near impedor 33 owing to can not reduce the interior combustion vibration of low-frequency range fully if do nothing.

Therefore, in this embodiment, first Road narrows 32 have the impedor 34 of a plurality of through holes, and its insertion also engages with the other end 32b.Identical with first impedor 33, impedor 34 is, stamped metal for example, ceramic post sintering metal or sintered metal net.

Construct as above-mentioned, the each pressure surge ("-" among the figure and "+") between first inner space 31 and first Road narrows, 32 inner spaces produces and differs.Therefore, thus, fluid fine particle vibrates near impedor 34 effectively.Therefore, although near the vibration of fluid fine particle first impedor 33 is insufficient, also can fully reduce the combustion vibration of low-frequency range.

In addition, when impedor 34 is placed on arbitrary position of the little end 32b of cross-section area in first Road narrows 32, rather than when the other end 32a, can obtain identical effect.

In other words, the structure of Fig. 9 and Figure 10 demonstration adopts by-pass pipe 11 as subject 20, according to above-mentioned first embodiment.In addition, the structure of Figure 11 demonstration adopts by-pass pipe 11 as subject 20, according to above-mentioned the 5th embodiment.

Here adopt by-pass pipe 11 to be that as the reason of subject 20 first inner space 31 needs certain size in order to reduce combustion vibration effectively, first Road narrows 32 need certain-length, and it is suitable having suitable adequate space near the by-pass pipe 11.Therefore, benefit is that first casing 30 is installed easily, thereby forms first inner space 31, and first Road narrows 32, fully guarantees effectively to reduce required first inner space 31 with certain size of combustion vibration, and first Road narrows 32 with certain-length.

In addition, according to above-mentioned first to the 8th embodiment, the shape of first Road narrows 32 and second Road narrows, 42 lateral cross section not only can be circular, and can be polygonal.

Then, with reference to figure the present invention the 9th to the 14 embodiment is described page number.Figure 12 is the vertical schematic section that shows according near the necessary part the gas turbine of ninth embodiment of the invention.In the drawings, identical mark is represented the part with Figure 47 same names and effect, will omit identical part.This is equally applicable to the tenth to the 14 embodiment of the present invention that hereinafter will describe.

Roughly identical according to the structure of the burner 3 of ninth embodiment of the invention with the structure used in the gas turbine that shows among Figure 47, but different in the following areas.Simply, as shown in figure 12, housing 150 is installed in the outside of the aft bulkhead of urceolus 8, forms the inner space with predetermined volume by the inner space of housing 150.In addition, housing 150 is connected on the aft bulkhead of urceolus 8 by the tubulose Road narrows 151 with predetermined length, Road narrows 150 have the end 151a that opening leads to urceolus 8, and just opening leads to the upstream region of zone of combustion, and the other end 151b opening leads to the inner space of housing 150.

Further, an end 151a of Road narrows 151 has the impedance with a plurality of through holes 152 that is inserted into and engages.Impedor 152 is, stamped metal for example, ceramic post sintering metal or sintered metal net.

Construct as above-mentioned, housing 150 holds the air that resonates with fluid fine particle as the air vessel body, the vibration key element of the combustion vibration that the fluid fine particle conduct takes place in the zone of combustion of burner flame tube 6 inside.In addition, Road narrows 151 connect urceolus 8 and housing 150 as connecting body.Yet impedor 152 passes the inside of Road narrows 151 as weft element, and its through hole is as the outlet of the fluid fine particle of vibration with the air resonance of first casing, 150 inside.In this way, for the combustion vibration that the zone of combustion in burner flame tube 6 inside takes place, fluid fine particle is diffused into the inside of urceolus 8 by burner flame tube 6 as the vibration key element; Can be caught by impedor 152 effectively; Then with housing 150 inner spaces in air resonance; Near vibration impedor 152.By this vibration, the Oscillation Amplitude of suppression fluid particulate has reduced combustion vibration.Therefore, the stable NOx that reduces.

Outlined arrow among the figure has shown compressed-air actuated the flowing by compressor 2 compressions.Pressurized air at first flows into the inside of housing 5; Then, behind the tubular space that the inner circumferential surface that passes by the periphery of burner flame tube 6 and urceolus 8 forms, about 180 degree that reverse make the inside that is introduced into burner flame tube 6 from rear portion side, then and burner flame tube 6 interior fuel carry out diffusive combustion and pre-mixing combustion.Therefore, the combustion gas of generation are discharged into the turbine 4 by transition piece 7 from its front end.

Secondly, with reference to Figure 13 the tenth embodiment of the present invention is described.The tenth embodiment is characterised in that the structure of having simplified according to the 9th embodiment's housing 150.This will make the inner space of housing 150 be in the pressure condition far above normal pressure.Yet, as shown in figure 12, when housing 150 self is installed in burner 3 outsides, just be lower than normal pressure, will produce significant pressure difference the inside and outside of housing 150, thereby the pressure-resistance structure of compression resistance difference is indispensable for housing 150.Therefore, can make housing 150 bigger than essential.

Therefore, according to this embodiment, housing 150 is installed in the inside of housing 5.In addition, in installation, only need crooked Road narrows 150 to make it to insert in the housing 5.Like this, housing 150 self is placed in the housing 5, and pressure of living in and inner space pressure are roughly the same, can not produce the pressure reduction between inside and outside.Therefore, housing 150 does not just need special pressure-resistance structure, does not need to make housing 150 bigger than essential.

Secondly, with reference to Figure 14 the 11st embodiment of the present invention will be described.The 11 embodiment is characterised in that and has changed the object that the end 151a opening according to the 9th and the tenth embodiment's Road narrows 151 leads to.

Simply, as shown in figure 14, an end 151a of Road narrows 151 leads to the inside of burner flame tube 6 from the upstream region part opening of the zone of combustion of burner flame tube 6 sidewalls.In addition, among Figure 14,, the housing 150 that is installed in the housing 5 is changed according to the tenth embodiment (referring to Figure 13).Yet, needless to say, can change (referring to Figure 12) according to the 9th embodiment.In this case, only need aft bulkhead or the sidewall of Road narrows 151 by urceolus 8 inserted and be connected on the inwall of burner flame tube 6.

Construct as above-mentioned, identical with the above-mentioned the 9th with the tenth embodiment, the air resonance in fluid fine particle and housing 150 inner spaces, vibration suppresses its Oscillation Amplitude near impedor 152.

In addition, the object that leads to of an end 151a opening of Road narrows 151 can be the sidewall of urceolus 8.

Secondly, with reference to Figure 15 and 16 12nd embodiment of the present invention will be described.The 12 embodiment is characterised in that the whole practicability of considering gas turbine, reduces combustion vibration.

Before describing related embodiment, will the general arrangement of the burner of gas turbine be described.Shown in Figure 15 and 16, gas turbine 1 has a plurality of burners 3 of installation, and main purpose is to provide rotating power to turbine 4 effectively.Specifically, with the equal angular same intervals each burner 3 is installed on the same circumference of relative main shaft J, this main shaft J directly connects air compressor 2 and turbine 4 (with 60 degree 6 burners being installed at interval among Figure 16).

The feature of related embodiment hereinafter will be described.With the concentric first ring-type body 130 of installing of main shaft J, be located at the outside of the aft bulkhead of each urceolus 8 with annular internal space.In addition, first Road narrows 131 of the tubulose of the first ring-type body 130 by having predetermined length are connected respectively on the aft bulkhead of each urceolus 8, each first Road narrows 131 has the end 131a that opening leads to each urceolus 8 inside, just opening leads to the upstream region of zone of combustion, and each the other end 131b opening leads to the inside of the first ring-type body 130.

Further, an end 131a of first Road narrows 131 has first impedor 132 with a plurality of through holes that is inserted into and engages.Identical with the impedor 152 according to the 9th to the 11 embodiment, first impedor 132 is, stamped metal for example, ceramic post sintering metal or sintered metal net.

As above-mentioned structure, the first ring-type body 130 is as the air vessel body, holds the air with the fluid fine particle resonance of the vibration key element of the combustion vibration that takes place as the zone of combustion in each burner flame tube 6 inside.In addition, each first Road narrows 131 connects each urceolus 8 and the first ring-type body 130 as connecting body.Yet each first impedor 132 passes the inside of first Road narrows 131 as weft element, and its through hole is as the outlet of the fluid fine particle of vibration with the air resonance of the first ring-type body, 30 inside.In this way, fluid fine particle can be caught by each first impedor 132 effectively as the vibration key element of the combustion vibration that the zone of combustion in each burner flame tube 6 inside takes place, resonate near vibration each first impedor 132 with the air of the first ring-type body, 130 inside that are connected by each first Road narrows 131.By this vibration, suppressed the Oscillation Amplitude of the fluid fine particle in each burner 3, reduced combustion vibration.Therefore, the stable NOx that reduces in the whole gas turbine, thus reduced the NOx in the waste gas.

Secondly, with reference to Figure 17 the 13rd embodiment of the present invention will be described.The 13 embodiment is characterised in that fluid fine particle is vibrated near each first impedor 132 according to the 12 embodiment effectively.Because the inner space according to the 12 embodiment's the first ring-type body 130 is a continuous space, can be created in the situation about differing of inner space generation pressure surge itself.In this case, fluid fine particle can not vibrate near each first impedor 132 fully, therefore, if do nothing, can not reduce combustion vibration fully.

Therefore, as shown in figure 17, the embodiment according to relevant installs first partition wall 135 respectively between each end 131b of each first Road narrows 131 in the first ring-type body 130.

As above-mentioned structure, for each first Road narrows 131, just the inner space for each burner 3, the first ring-type body 130 is separated by first partition wall 135 as a continuous space, produces differing of pressure surge in the space that separates separately thereby be suppressed at.Therefore, because fluid fine particle can vibrate fully effectively, can reduce combustion vibration fully near each first impedor 132.

Secondly, with reference to Figure 18 the 14th embodiment of the present invention will be described.The 14 embodiment is characterised in that and can reduces effectively according to the 12 and the 13 embodiment's combustion vibration.

Simply, as shown in figure 18, according to relevant embodiment, in the outside of the first ring-type body 130, become row that second concentric with main shaft J, as the to have annular inner space ring-type body 140 is installed in the mode identical with the first ring-type body 130.In addition, the second ring-type body 140 is respectively by having predetermined length, being connected on the first ring-type body 130 with second Road narrows 141 of each first Road narrows, 131 corresponding tubulose, second Road narrows 141 have be positioned at the first ring-type body, 130 sides, each end 141a that opening leads to the first ring-type body, 130 inside, have be positioned at the second ring-type body, 140 sides, each the other end 141b that opening leads to the second ring-type body, 140 inside.

Further, each end 141a of each second Road narrows 141 has second impedor 142 with a plurality of through holes that is inserted into and engages.Identical with first impedor 132, second impedor is, for example, and stamped metal, ceramic post sintering metal or sintered metal net.

As above-mentioned structure, near not only vibration each first impedor 132 of fluid fine particle, and resonate with air in the second ring-type body 140 that is connected by each second Road narrows 141, and each second impedor 142 near, vibrate, suppress its Oscillation Amplitude.Therefore, fluid fine particle is vibrated in a plurality of positions, thereby effectively reduce combustion vibration.

Among Figure 18,140 one-tenth row of the second ring-type body are arranged at the first ring-type body 130, and needless to say, can become row to install more than two.In this case, separately by the second above-mentioned Road narrows 140, be merely able to connect the second ring-type body 141 of adjacency.

In addition, for the purpose identical, in the second ring-type body 140, between each end 141b of each second Road narrows 141 the second partition wall (not shown) is installed respectively with the 13 embodiment.Do like this, for each second Road narrows 141, just the inner space for each burner 3, the second ring-type body 140 that passes through first Road narrows 131 is separated by second partition wall as a continuous space, thereby is suppressed at differing of each space segment generation pressure surge.Therefore and since fluid fine particle can be fully effectively near vibration each second impedor 142, combine (couple) with near the vibration of the fluid fine particle of each first impedor 132, reduce combustion vibration more up hill and dale.

Yet the object that an end 131a opening of each first Road narrows 131 leads to can be the sidewall of burner flame tube 6 or the sidewall of urceolus 8, as long as it is the part of the upstream region of zone of combustion.

In addition, according to above-mentioned the 9th to the 14 embodiment, the shape of the cross section of Road narrows 151 or first Road narrows 131 or second Road narrows 141 is not limited to circle, can be polygonal.

Secondly, according to figure the 15 to the 21 embodiment of the present invention will be described successively.Figure 19 is the longitdinal cross-section diagram according to the burner of fifteenth embodiment of the invention, and Figure 20 is the view in transverse section of the necessary part of burner.In addition, among the figure, identical mark represent with Figure 47 in have the part of same names and same function, will omit identical explanation.This is equally applicable to the 16 to the 21 embodiment of the present invention that hereinafter will describe.

The gas turbine that is applied to show among Figure 47 according to the 15 embodiment's burner 3.As Figure 19 and shown in Figure 20, transition piece 7 is connected to the front end of burner flame tube 6 (not shown) with zone of combustion, by the burner flame tube 6 and transition piece 7 structures one cylinder of downstream area.By-pass pipe 11 is connected on the sidewall of transition piece 7, and an end 11a opening leads to the inside of transition piece 7, and the other end 11b opening leads to the inside of the housing 5 that forms the cylinder periphery.

Further, by-pass pipe 11 has the plank model component 250 of cross setting therein, forms a plurality of through holes 251 on the plank model component 250.Plank model component 250 like this is not limited to have the sheet metal of the through hole 251 of break-through, stamped metal, and ceramic post sintering metal or sintering sintered metal net also are suitable for.

As above-mentioned structure, housing 5 is as the air vessel body, holds the air with the fluid fine particle resonance of the vibration key element of the combustion vibration that takes place as the zone of combustion in each burner flame tube 6 inside.In addition, by-pass pipe 11 connects transition piece 7 and housing 5 as connecting body.Yet plank model component 250 passes the inside of by-pass pipe 11 as weft element, and through hole 251 is as the outlet of the fluid fine particle of vibration with the air resonance of housing 5 inside.In this way, the fluid fine particle conduct can be propagated by transition piece 7 in the vibration key element of the combustion vibration of the zone of combustion of burner flame tube 6 inside generation; Then the end 11a from by-pass pipe 11 is introduced into, and is caught effectively by each through hole 251 of plank model component 250; Resonate with the air in the housing 5 that is connected by by-pass pipe 11, by each through hole 251 vibration.By this vibration, suppressed the Oscillation Amplitude of fluid fine particle, reduced combustion vibration.Therefore, realize the stable NOx of minimizing.

In addition, among Figure 19, a plank model component 250 is installed in by-pass pipe 11, and needless to say, can be become row to install more than two.

Secondly, with reference to Figure 21 to Figure 25 A and 25B the 16th embodiment of the present invention will be described.The 16 embodiment is characterised in that:

At first, do not damage by-pass pipe 11 original functions and reduce combustion vibration;

Secondly, in the different frequency scope, can respond easily various combustion vibrations.

First feature request by-pass pipe 11 has original function, and from the inside that housing 5 is introduced cylinder (transition piece 7), the concentration of regulating combustion gas is just regulated the function that bypass air flows with bypass air.This is because when keeping with the 15 embodiment's identical construction, plank model component 250 makes bypass air mobile insufficient as an obstacle, causes the irrealizable such a case of by-pass pipe 11 original functions.

Second feature is for because in the corresponding zone of the lateral cross section with by-pass pipe 11 of plank model component 250, the inhibition responsiveness of the various frequency ranges of combustion vibration is determined that by the ratio (hereinafter often being called " aperture efficiency ") that through hole 251 accounts for opening area therefore the frequency range according to combustion vibration suppresses the situation that responsiveness is significantly worsened.

Therefore, according to relevant embodiment, as shown in figure 21, plank model component 250 laterally slides relative to by-pass pipe 11 and moves (arrow X among the figure).As shown in figure 22, plank model component 250, roughly the same with the size of the lateral cross section 11c of by-pass pipe 11, have and form the through hole area A1 that the ratio account for opening area differs from one another, A2......, further, have the penetrating region B of the formation of penetrating, the size of this penetrating region B and lateral cross section 11c is roughly the same.In addition, among Figure 21, through hole area A2 is bigger than the aperture efficiency of through hole area A1.

Yet by-pass pipe 11 has the by-pass valve 12 that contiguous plank model component 250 is installed.Identical with plank model component 250, laterally (arrow Y among Figure 21) slip is mobile in by-pass pipe 11 for by-pass valve 12.Specifically, because at the same circumference of relative gas turbine 1 main shaft, a plurality of burners 3 are installed with same intervals, angle, by-pass valve 12, as shown in figure 23, have with the concentric ring-like plate of the main shaft of gas turbine 1 as support plate part 12a, mounting support plate portion 12a makes the by-pass pipe 11 that passes each burner 3.Support plate part 12a have respectively form wherein with each by-pass pipe 11 corresponding through hole 12b, be fixed with the bar 12c that radially gives prominence to and be connected to by-pass valve adjusting mechanism 13 (referring to Figure 47) at the periphery of support plate part 12a.

Therefore, by operation by-pass valve varistructure 12, bar 12c is circumferentially moving, and like this, support plate element 12a is circumferentially sliding and rotating, and just slides at horizontal (the arrow Y among Figure 21) relative to each by-pass pipe 11 and moves.

With reference to Figure 24 A and 24B and Figure 25 A and 25B, the operating condition of the burner 3 of above-mentioned structure will be described hereinafter.At first, in order to regulate flowing of bypass air, this is by-pass pipe 11 original functions, shown in Figure 24 A and 24B, and the mobile plank model component 250 that slides, and select to make the corresponding area coincidence of cross section of penetrating region B and by-pass pipe 11.The by-pass pipe 12 that slides is in this case regulated the degree that by-pass pipe 12 opens and closes, thereby regulates flowing of bypass air, and this is by-pass pipe 11 original functions.

For example, when closing by-pass pipe 11, when bypass air stops to flow into, slide and select plank model component 250 to make the corresponding area coincidence of cross section of penetrating region B and by-pass pipe 11, simultaneously, slip by-pass valve 12 makes it not cover through hole 12b.(referring to Figure 24 A).Equally, when opening by-pass pipe 11 fully, when bypass air flowed into fully, slip by-pass valve 12 made the corresponding area coincidence of cross section of through hole 12b and by-pass pipe 11.(referring to Figure 24 B).In addition, when regulating the medium inflow of bypass air, only regulate opening rate, it is regional accordingly that through hole 12b is partly covered with the cross section of by-pass pipe.

When reducing combustion vibration, shown in Figure 25 A and 25B, the mobile by-pass valve 12 that slides, and selection makes the corresponding area coincidence of cross section of through hole 12b and by-pass pipe 11.Simply, by-pass pipe 11 is in the position of opening fully.The plank model component 250 that slides in this case selects to make the through hole area A1 suitable with the frequency range of various combustion vibrations, the corresponding area coincidence of cross section of A2...... and by-pass pipe 11.For example, Figure 25 A shows the situation of selecting through hole area A1, and Figure 25 B shows the situation of selecting through hole area A2.Like this, guarantee the responsiveness of the combustion vibration of blanketing frequency scope, thereby reduce combustion vibration.

Therefore, can not damage the original function of by-pass pipe, reduce the combustion vibration of different frequency scope really.

Secondly, with reference to Figure 26 and Figure 27 the 17th embodiment of the present invention will be described.The 17 embodiment is characterised in that identical with the 16 embodiment, does not damage the original function of by-pass pipe, reduces combustion vibration, simultaneously, responds the various combustion vibrations of different frequency scope easily, further simplified structure.

Simply, as Figure 26 and shown in Figure 27, according to related embodiment, removal is according to the 16 embodiment's by-pass valve 12, as an alternative, except through hole area A1, beyond A2...... and the penetrating region B, plank model component 250 has the roughly the same and no through hole area C that do not have through hole 251 of size of the cross section 11c of formation and by-pass pipe 11.

As above-mentioned structure, when regulating bypass air and flow, the plank model component 250 that suitably slides, and select to make through hole area A1, A1......, penetrating region B and do not have through hole area C and the corresponding area coincidence of by-pass pipe 11 cross sections.Like this, regulate the degree that by-pass valve 12 opens and closes, thereby regulate flowing of bypass air, this is by-pass pipe 11 original functions.

On the other hand, when reducing combustion vibration, slip plank model component 250, and select to make the through hole area A1 suitable with the various frequency ranges of combustion vibration, A2 is with the corresponding area coincidence of the cross section of by-pass pipe 11.Like this, guarantee the responsiveness of the combustion vibration of blanketing frequency scope, thereby reduce combustion vibration.

Therefore, identical with the 6th embodiment, do not damage the original function of by-pass pipe, determine to reduce the combustion vibration of different frequency scope, in addition, do not need to install separately to resemble the such by-pass pipe of the 16 embodiment 12.In other words, because the function of by-pass pipe 11 is shared by plank model component, benefit is simple in structure.

Secondly, with reference to Figure 28 the 18th embodiment of the present invention will be described.The 18 embodiment is characterised in that in the burner 3 according to the 15 to the 17 embodiment, can regulate the degree that reduces combustion vibration.This is because the degree that reduces combustion vibration is changing in the distance L between the plank model component 250 from the opening end (Figure 19, the end 11b of Figure 20 and Figure 26) to the housing 5 of by-pass pipe 11.

Therefore, according to relevant embodiment, cylindrical elements 255 axially outstanding and that have a predetermined length insert and with an end 11b who engages by-pass pipe 11.Make cylindrical elements 255 outstanding like this, make distance L roughly extend to the top of cylindrical elements 255 from plank model component 250.Therefore, because the overhang by regulating cylindrical elements 255 can the free adjustment distance L, the minimizing degree of the combustion vibration that can regulate fluctuates according to distance L.Therefore, this setting can reduce combustion vibration fully.

Secondly, with reference to Figure 29 the 19th embodiment of the present invention will be described.The 19 embodiment is characterised in that, in the burner 3 according to the 15 to the 18 embodiment, the air that is used to cause the resonance of fluid fine particle vibration is the air in the housing 5, and according to relevant embodiment, the air in the bypass 11 also are used for like this.

Simply, according to related embodiment, as shown in figure 29, an end 11a of by-pass pipe 11 has the partition wall 260 of installing in its vicinity and crossing wherein, and partition wall 260 has the outstanding pipe 261 that penetrates partition wall 260 and penetrate its at least one surface.Further, in outstanding pipe 261, the impedor 262 with a plurality of through holes is inserted into and engages.For impedor 262, for example, can use stamped metal, ceramic post sintering metal or sintered metal net.

As above-mentioned structure, by-pass pipe 11 holds and the air of conduct in the fluid fine particle resonance of the vibration key element of the combustion vibration of the zone of combustion of each burner flame tube 6 inside generation as the air vessel body.In addition, partition wall 260 and outstanding pipe 261 connect transition piece 7 and by-pass pipe 11 as connecting body.Yet impedor 262 passes the inside of outstanding pipe 261 as weft element, and its through hole is as the outlet of the fluid fine particle of vibration with the air resonance of by-pass pipe 11 inside.In this way, combustion vibration for the generation of the zone of combustion in burner flame tube 6, fluid fine particle is propagated by transition piece 7, then the end 11a from by-pass pipe 11 is introduced into, the impedor 262 that is highlighted in the pipe 261 is caught effectively, then with 11 the other end 11b that is connected by outstanding pipe 261 from partition wall 260 to by-pass pipe the space in air resonate, near impedor 262, vibrate.By this vibration, suppressed the Oscillation Amplitude of fluid fine particle, reduced combustion vibration.Therefore, the stable NOx that reduces.

In addition, in Figure 29, a partition wall 260 is installed an outstanding pipe 261 and an impedor 262, yet needless to say, can become row to install more than two.

Secondly, with reference to Figure 30 the 20th embodiment of the present invention will be described.The 20 embodiment is characterised in that and can reduces effectively according to the combustion vibration in the 19 embodiment's the burner 3.

Simply, according to related embodiment, as shown in figure 30, a plurality of partition walls 260 are configured to row, and each in these partition walls 260 provides outstanding pipe 261 and impedor 262.Like this, fluid fine particle and the air resonance of giving prominence to by each in each space of managing between 261 partition walls that are connected 260, vibration suppresses its Oscillation Amplitude near each impedor 262.Therefore, can vibrate fluid fine particles in a plurality of positions, thereby reduce combustion vibration effectively.

Secondly, the 21st embodiment of the present invention will be described.The 21 embodiment is characterised in that, reduces effectively according to the combustion vibration in the 15 to the 20 embodiment's the burner 3.Figure 31 shows this example of structure.

In Figure 31, except the plank model component 250 according to the 15 to the 18 embodiment, by-pass pipe 11 has the casing 230 of the sidewall outer that is installed in it, and the cavity in the casing 230 forms the inner space 231 with predetermined volume.In addition, casing 230 is connected on the sidewall of by-pass pipe 11 by the tubulose Road narrows 232 with predetermined length, and Road narrows 232 openings lead to the inside and the inner space 231 of bypass duct 11.

In addition, Road narrows 232 have the impedor with a plurality of through holes 233 that is inserted into and engages.With according to the 19 identical with second embodiment's impedor 262, impedor 233 is, stamped metal for example, ceramic post sintering metal or sintered metal net.

As above-mentioned structure, combustion vibration for the generation of the zone of combustion in burner flame tube 6, fluid fine particle is not only in through hole 252 internal vibrations of plank model component 250, and resonate with the air of the inner space 231 that is connected by Road narrows 232, and near the impedor 233 of Road narrows 232, vibrate, thereby suppress its Oscillation Amplitude.Therefore, reduce combustion vibration more fully.

In addition, among Figure 31, as the basis, add as the casing 230 of the feature member of related embodiment etc. according to the 15 to the 18 embodiment's structure.Yet much less, can on structure, add according to the 19 to the 20 embodiment.Equally, the object that connects by Road narrows 232 is not limited to the wall surface of by-pass pipe 11, also can be the wall surface or the transition piece 7 of burner flame tube 6.

Secondly, with reference to figure the 22 to the 31 embodiment of the present invention will be described.Figure 32 is the longitdinal cross-section diagram according to the necessary part of the burner of the 22nd embodiment of the present invention, and Figure 33 is the resonator of burner of circumferential section and expansion and the cross section projection drawing of first casing.In addition, in the drawings, identical mark represents to have the part with Figure 47 same names and identical function, will omit identical part.This is equally applicable to the 23 to the 31 embodiment of the present invention that hereinafter will describe.

The gas turbine that is applied to show among Figure 47 according to the 22 embodiment's burner 3.As shown in Figure 32, by having transition piece 7 construct column that are connected to burner flame tube 6 front ends, and this cylinder have with cylinder in combustion gas produce the zone of combustion F of combustion vibration.On the sidewall of boundary's transition piece 7, an end opening leads to the inside of transition piece 7 to by-pass pipe 11 in succession, and the other end opening leads to housing 5 (not shown) of the outer surface that forms cylinder.

Periphery around near the sidewall the zone of combustion F in the transition piece 7 is installed resonator 320 (hereinafter often being called " acoustic resonator (acoustic liner) "), by the sidewall of acoustic resonator 320, the sidewall of front bulkhead and aft bulkhead and transition piece 7 forms cavity 321.Yet, on the sidewall of transition piece 7, form a plurality of sound absorption holes 322 from its inner penetrated cavity 321, be evenly distributed.

In addition,, first casing 330 is installed, is made the position adjacent and along the sidewall of transition piece 7 in the outside of acoustic resonator 320 front bulkheads as Figure 32 and shown in Figure 33.By front bulkhead, the sidewall of first casing 330, the sidewall of the front bulkhead of acoustic resonator 320 and transition piece 7 forms first inner space 331 with predetermined volume.In addition, the front bulkhead of acoustic resonator 320 is provided with first Road narrows 332 of giving prominence to, have predetermined length towards first inner space 331, first Road narrows 332 have the end 332a that opening leads to the cavity 321 of acoustic resonator 320, and the other end 332b opening leads to first inner space 331.

As above-mentioned structure, first casing 330 holds and the air of conduct in the fluid fine particle resonance of the vibration key element of the combustion vibration of the low-frequency range of the zone of combustion of burner flame tube 6 inside generation as the air vessel body.In addition, acoustic resonator 320 and first Road narrows, 332 usefulness connect shell, connect the transition piece 7 and first casing 330.Yet the sidewall of transition piece 7 passes the inside of acoustic resonator 320 as weft element, and further, through hole 332 is as the outlet of the fluid fine particle of the low-frequency range of vibration with the air resonance of first casing, 330 inside.In this way, for the combustion vibration that takes place at zone of combustion F, fluid fine particle is as the vibration key element of the combustion vibration of high-frequency range and the air resonance in the cavity 321 in the acoustic resonator 320, and hole 322 vibrations of passing through to absorb sound, thereby suppresses its Oscillation Amplitude.

On the other hand, fluid fine particle resonates by the air in cavity 321 and first Road narrows 332 and first inner space 331 as the vibration key element of low-frequency range, and by 322 vibrations of sound absorption hole, thereby suppress its Oscillation Amplitude.In this way, can not consider frequency range and reduce Oscillation Amplitude, therefore, the stable NOx that reduces.

In addition, in Figure 32 and Figure 33, first casing 330 is installed one first Road narrows 332, yet much less, can install more than two.

Secondly, with reference to Figure 34 and Figure 35 the 23rd embodiment of the present invention will be described.The 23 embodiment is characterised in that and has avoided among the 22 embodiment to combustion vibration the particularly reaction of the combustion vibration of high-frequency range.This be because except expection with acoustic resonator 320 in cavity 321 in air resonance; fluid fine particle is also sometimes by the resonance of the air in first Road narrows 332 and first inner space 331; in this case; the 322 inner fluid particulates vibration of sound absorption hole becomes insufficient, has reduced the effect that reduces the combustion vibration of high-frequency range.

Therefore, according to related embodiment, as showing in Figure 34 and 35 that first Road narrows 332 have first impedor 333 with a plurality of through holes that is inserted into and engages with an end 332a.First impedance 333 is, stamped metal for example, ceramic post sintering metal or sintered metal net.

As above-mentioned structure, first impedor 333 has played the effect of barrier, thereby the air in the inhibition and first inner space 331 resonates.Like this, guaranteed that the air in the cavity 321 with acoustic resonator 320 resonates, therefore, fluid fine particle can vibrate effectively by sound absorption hole 322, thereby suppresses its Oscillation Amplitude.In addition, for the combustion vibration of low-frequency range, guaranteed with first inner space 331 in air resonate, fluid fine particle is used as first impedor 333 of impedance and catches effectively, in its vicinity the vibration, thereby suppress its Oscillation Amplitude.

Secondly, with reference to Figure 36 and Figure 37 the 24th embodiment of the present invention will be described.The 24 embodiment is characterised in that, has considered the combustion vibration of the 23 embodiment's medium and low frequency scope especially.When in low-frequency range generation combustion vibration, the section area according to the 22 embodiment's first Road narrows 332 is diminished.Yet if do like this, the zone at first impedor, 333 places unavoidably also will diminish, and this can reduce the ratio of catching fluid fine particle, causes on the whole reducing combustion vibration fully.

Therefore, according to related embodiment, as Figure 36 and shown in Figure 37, first Road narrows 332 adopt this stepped shaft tubular body, and its inner circumference promptly is stretched over the other end 332a by an end 332b near the center, and an end 332a open area ratio the other end 332b is big.One end 332a has first impedor 333 that is inserted into and engages.

Owing to adopt this mode, can make the sectional area in first Road narrows 332, just the other end 332b diminishes, and can enlarge the area at first impedor, 333 places simultaneously, increase the ratio of the fluid fine particle of catching low-frequency range, thereby help to reduce combustion vibration on the whole.Therefore, can reduce the combustion vibration of low-frequency range on the whole fully.

In addition, the horn-like object that inner circumference enlarges gradually can be used as first Road narrows 332, can obtain same effect.

Secondly, with reference to Figure 38 and Figure 39 the 25th embodiment of the present invention will be described.The 25 embodiment is characterised in that the reaction that consideration produces according to the 24 embodiment.According to the 24 embodiment, because the open area ratio the other end 332b of an end 332a of first Road narrows 332 is big, in other words, because it is big that the volume of first Road narrows 332 becomes, can not produced differing of each pressure surge usually between first Road narrows, 332 inner spaces of first impedor, 333 isolation and the cavity 321 in the acoustic resonator 320.In this case, because fluid fine particle does not vibrate,, can produce the such reaction of combustion vibration that can not reduce low-frequency range fully near first impedance 333 if do nothing.

Therefore, according to related embodiment, as Figure 38 and shown in Figure 39, an end 332b of first Road narrows 332 has first impedor 334 with a plurality of through holes that is inserted into and engages.Identical with first impedor 333, impedor 334 is, stamped metal for example, ceramic post sintering metal or sintered metal net.

As above-mentioned structure, owing to produce differing of each pressure surge between the space in first inner space 331 and first Road narrows 332, for fluid fine particle is vibrated near impedor 334 effectively, by doing like this, although fluid fine particle can not vibrate fully, can reduce the combustion vibration of low-frequency range fully near first impedor 333.

Yet, in any side of an end 332b littler impedor 334 is installed than the cross-section area of the other end 332a of first Road narrows 332, also can obtain same effect.
