氣體燃燒器Gas burner 發明領域Field of invention

本發明係關於一種氣體燃燒器,係具有環狀主燃燒器及配置於該主燃燒器之中央部的中央燃燒器者。The present invention relates to a gas burner having an annular main burner and a central burner disposed at a central portion of the main burner.

發明背景Background of the invention

習知有一種氣體燃燒器為人所知,其係於環狀主燃燒器之中央部設置中央燃燒器,而將燃料氣體與一次空氣的混合氣體分配供給至主燃燒器和中央燃燒器來使其燃燒(參照專利文獻1)。A gas burner is known which is provided with a central burner at the center of the annular main burner, and a mixed gas of fuel gas and primary air is supplied to the main burner and the central burner to make It burns (refer to Patent Document 1).

上述氣體燃燒器中,由中央燃燒器內部的分佈室放射狀地延伸的氣體供給通路,係連通至主燃燒器內部所形成的環狀分佈室,而供給至主燃燒器的混合氣體則透過氣體供給通路也供給至中央燃燒器。In the gas burner described above, the gas supply passage radially extending from the distribution chamber inside the central burner is connected to the annular distribution chamber formed inside the main burner, and the mixed gas supplied to the main burner is permeated through the gas. The supply passage is also supplied to the central burner.

【專利文獻1】日本實公昭61-26734號公報(第1圖、第2圖)[Patent Document 1] Japanese Patent Publication No. 61-26734 (Fig. 1 and Fig. 2)

惟,就經過主燃燒器將混合氣體供給至中央燃燒器之構造而言,主燃燒器分佈室內之混合氣體的一部分會產生朝向中央燃燒器之流動。因此,有主燃燒器之環狀分佈室整個周邊的混合氣體分佈不均之問題。However, in the configuration in which the mixed gas is supplied to the central burner through the main burner, a part of the mixed gas in the main burner distribution chamber generates a flow toward the central burner. Therefore, there is a problem that the mixed gas distribution around the entire circumference of the annular distribution chamber of the main burner is uneven.

有鑑於此,本發明之目的在於提供一種氣體燃燒器,其係可使混合氣體確實地分配分佈於主燃燒器及中央燃燒器,不論火力皆可得到良好燃燒。In view of the above, it is an object of the present invention to provide a gas burner which can reliably distribute a mixed gas to a main burner and a central burner, and can achieve good combustion regardless of fire power.

本發明係一種氣體燃燒器,包含有:環狀主燃燒器;中央燃燒器,係配置設於該主燃燒器之中央部者;氣體導入室,係隔著分隔壁相連設置於該中央燃燒器之下部者;筒狀喉部,係上游端與噴出燃料氣體之噴嘴相對向,可與燃料氣體一同取入一次空氣而開放,且下游端於前述氣體導入室之底部朝上開口;複數主燃燒器用氣體供給通路,係自前述氣體導入室朝水平方向放射狀地延伸而連接於前述主燃燒器,並將由前述喉部已導入至前述氣體導入室之燃料氣體和一次空氣之混合氣體供給至前述中央燃燒器者;及中央燃燒器用氣體供給通路,係自於前述分隔壁之下面開口的入口引入前述氣體導入室的混合氣體,並供給至前述中央燃燒器者,其特徵在於:在與前述分隔壁下面之前述喉部的下游端開口相對向之區域外側、且於彼此相鄰之前述主燃燒器用氣體供給通路之間,設有前述中央燃燒器用氣體的入口;在較前述中央燃燒器用氣體供給通路的入口水平方向外側且彼此相鄰之前述主燃燒器用氣體供給通路之間,設有供沿著前述分隔壁的下面流動之混合氣體碰碰撞的側面壁。The present invention relates to a gas burner comprising: an annular main burner; a central burner disposed at a central portion of the main burner; and a gas introduction chamber connected to the central burner via a partition wall a lower portion; the tubular throat is opposite to the nozzle for ejecting the fuel gas, and can be opened together with the fuel gas to open the air, and the downstream end is open upward at the bottom of the gas introduction chamber; the plurality of main combustion The gas supply passage for the device is radially extended from the gas introduction chamber and connected to the main burner, and the mixed gas of the fuel gas and the primary air introduced into the gas introduction chamber by the throat portion is supplied to the foregoing a central burner; and a gas supply passage for the central burner, which is introduced into the gas inlet chamber from an inlet opening at a lower surface of the partition wall, and supplied to the central burner, characterized in that The downstream end of the throat portion below the partition wall is open to the outside of the region and adjacent to the main burner gas adjacent to each other An inlet for the gas for the central burner is provided between the supply passages, and between the gas supply passages for the main burners which are adjacent to each other in the horizontal direction of the inlet of the gas supply passage for the central burner, are provided along the aforementioned The mixed gas flowing under the partition wall hits the side wall of the collision.

依據本發明,首先,當自噴嘴向前述喉部的上游端噴出燃料氣體時,周圍的空氣會因燃料氣體的流動而作為燃燒用的一次空氣被捲入喉部,燃料氣體和一次空氣的混合氣體會自喉部進入前述氣體導入室。According to the present invention, first, when the fuel gas is ejected from the nozzle toward the upstream end of the throat, the surrounding air is taken into the throat as a primary air for combustion due to the flow of the fuel gas, and the fuel gas and the primary air are mixed. Gas enters the aforementioned gas introduction chamber from the throat.

喉部之下游端於氣體導入室的底部朝上開口。因此,進入氣體導入室的混合氣體會碰撞到位於喉部下游端正上方之前述分隔壁的下面。碰撞到分隔壁下面之混合氣體會變為沿著分隔壁下面水平地擴散般之氣流,朝前述主燃燒器用氣體供給通路或前述中央燃燒器用氣體供給通路流動。The downstream end of the throat opens upward at the bottom of the gas introduction chamber. Therefore, the mixed gas entering the gas introduction chamber collides with the lower side of the aforementioned partition wall directly above the downstream end of the throat. The mixed gas that has collided under the partition wall becomes a gas stream that spreads horizontally along the lower surface of the partition wall, and flows toward the main burner gas supply passage or the central burner gas supply passage.

流向主燃燒器用氣體供給通路的混合氣體係通過主燃燒器用氣體供給通路而進入主燃燒器內。由於主燃燒器用氣體供給通路為放射狀地設置複數個,因此通過這些主燃燒器用氣體供給通路之混合氣體,會被有效率地引導到主燃燒器的內部,並在環狀主燃燒器的整個周邊均一地分佈。The mixed gas system flowing to the main burner gas supply passage enters the main burner through the main burner gas supply passage. Since a plurality of gas supply passages for the main burner are radially provided, the mixed gas passing through the main burner gas supply passages is efficiently guided to the inside of the main burner and is entirely throughout the annular main burner. The surroundings are evenly distributed.

另一方面,流向主燃燒器用氣體供給通路以外的混合氣體則流向中央燃燒器用氣體供給通路。此時,中央燃燒器用氣體供給通路的入口係設於彼此相鄰的主燃燒器用氣體供給通路之間,因此可防止朝向主燃燒器用氣體供給通路之混合氣體流因朝向中央燃燒器用氣體供給通路之混合氣體流而受到阻礙。On the other hand, the mixed gas flowing out of the main burner gas supply passage flows to the central burner gas supply passage. In this case, since the inlet of the gas supply passage for the central burner is disposed between the main burner gas supply passages adjacent to each other, it is possible to prevent the mixed gas flow toward the main burner gas supply passage from being directed toward the central burner gas supply passage. The mixed gas flow is hindered.

在此,本發明係將中央燃燒器用氣體供給通路之入口,設於與分隔壁下面之喉部下游端開口相對向之區域外側。藉此,自喉部下游端朝上流動的混合氣體,便不會直線地侵入中央燃燒器用氣體供給通路而不改變其流動方向,防止混合氣體過剩供給至中央燃燒器。Here, in the present invention, the inlet of the gas supply passage for the center burner is provided outside the region facing the downstream end opening of the throat below the partition wall. Thereby, the mixed gas flowing upward from the downstream end of the throat does not linearly intrude into the gas supply passage for the central burner without changing the flow direction thereof, and prevents the mixed gas from being excessively supplied to the central burner.

惟,由於中央燃燒器用氣體供給通路之入口在分隔壁的下面開口,因此特別是以大火力燃燒而混合氣體的流速比較快時,將無法大幅地改變流動方向,其大部分不會進入中央燃燒器用氣體供給通路而朝水平方向通過。However, since the inlet of the gas supply passage for the central burner is opened below the partition wall, especially when the flow rate of the mixed gas is relatively high when the combustion is performed with a large firepower, the flow direction cannot be greatly changed, and most of the gas does not enter the central combustion. The device passes through the gas supply passage and passes in the horizontal direction.

因此,本發明係設置前述側面壁,使朝向中央燃燒器用氣體供給通路的混合氣體碰撞側面壁。藉此,不進入中央燃燒器用氣體供給通路而朝水平方向通過的混合氣體,會碰撞到側面壁而改變流動方向,流向中央燃燒器用氣體供給通路。故,即使是以大火力燃燒而混合氣體之流速較快時,也可將足量的混合氣體可供給至中央燃燒器。Therefore, in the present invention, the side wall is provided such that the mixed gas toward the central burner gas supply passage collides with the side wall. As a result, the mixed gas that does not enter the central burner gas supply passage and passes in the horizontal direction collides with the side wall to change the flow direction, and flows to the central burner gas supply passage. Therefore, even when the flow rate of the mixed gas is high by the large fire power, a sufficient amount of the mixed gas can be supplied to the central burner.

如此一來,依據本發明,可將混合氣體確實地分配於主燃燒器和中央燃燒器而無過與不足分佈之狀況,無論火力皆可得到良好的燃燒。In this way, according to the present invention, the mixed gas can be surely distributed to the main burner and the central burner without excessive or insufficient distribution, and good combustion can be obtained regardless of the fire power.

又,本發明中,宜在與前述分隔壁下面之前述喉部下游端開口對應之位置,設置朝該開口***的***部。該***部係於其外周形成高低差。藉此,來自喉部的混合氣體會碰撞分隔壁下面的***部,變為沿著***部水平擴展的氣流後,藉由***部外周的高低差促進氣體朝前述主燃燒器用氣體供給通路及前述中央燃燒器用氣體供給通路之流動。故,來自喉部之混合氣體會經過主燃燒器用氣體供給通路及前述中央燃燒器用氣體供給通路,順暢地供給至主燃燒器及中央燃燒器,而可得到更良好的燃燒。Further, in the invention, it is preferable that a ridge portion that is raised toward the opening is provided at a position corresponding to the opening of the throat downstream end of the partition wall. The ridge portion is formed with a height difference on its outer circumference. Thereby, the mixed gas from the throat collides with the ridge portion under the partition wall, and becomes a gas flow extending horizontally along the ridge portion, and then the gas is supplied to the main burner gas supply passage by the height difference of the outer periphery of the ridge portion and the aforementioned The flow of the gas supply passage for the central burner. Therefore, the mixed gas from the throat passes through the main burner gas supply passage and the central burner gas supply passage, and is smoothly supplied to the main burner and the central burner, thereby achieving better combustion.

As shown in FIGS. 2 and 3, the central burner distribution chamber 14 and the gas introduction chamber 16 communicate with each other through the central burner gas supply passage 17 that penetrates the partition wall 11 up and down.

主燃燒器8係由外周壁18、於與外周壁同圓心之內側存有預定間隔而設置之內周壁19、載置於外周壁18和內周壁19的上緣而覆蓋主燃燒器8的外周壁18之環狀主燃燒器蓋20、以及一體地相連設置於前述喉部10且朝其外側伸出之圓盤狀底板21所構成。The main burner 8 is provided with an outer peripheral wall 18, an inner peripheral wall 19 provided at a predetermined interval from the inner side of the outer peripheral wall, and an outer periphery of the outer peripheral wall 18 and the inner peripheral wall 19 to cover the outer periphery of the main burner 8. An annular main burner cover 20 of the wall 18 and a disk-shaped bottom plate 21 integrally connected to the throat 10 and projecting outward are formed.

如第3圖所示,於主燃燒器8的外周壁18存有圓周方向的間隔,形成多個深度相異之溝槽。因此,如第2圖所示,當於主燃燒器8的外周壁18以及內周壁19上載置主燃燒器蓋20時,會形成由底板21、外周壁18、內周壁19及主燃燒器蓋20所包圍的空間,而可將此空間作為主燃燒器8的主燃燒器分佈室22。同時,主燃燒器8的外周壁18前述溝槽的上面會被主燃燒器蓋20覆蓋產生連通至主燃燒器分佈室22的孔洞,如第1圖所示,主燃燒器8的外周可劃分成多個焰孔23。As shown in Fig. 3, a circumferential gap is formed in the outer peripheral wall 18 of the main burner 8, and a plurality of grooves having different depths are formed.

The bracket 3 is composed of a base portion 28 that is coupled and fixed to the chassis 7, a support column portion 29 that is erected on one side of the base portion 28, and a holding portion 30 that is partially supported by the support column portion 29 and that holds the throat portion 10. The base portion 28, the support post portion 29, and the holding portion 30 are integrally formed of a metal block such as an aluminum alloy.

支架3的基部28內部形成有燃料氣體的氣體通路31,其上方安裝有連通於氣體通路31的噴嘴27。噴嘴27將燃料氣體朝垂直上方噴射。燃料氣體由噴嘴27向喉部10噴出時,該燃料氣體會捲入周圍空氣做為一次空氣並進入喉部,在喉部10內部及前述氣體導入室16生成燃料氣體和一次空氣之混合氣體。A gas passage 31 for fuel gas is formed inside the base portion 28 of the bracket 3, and a nozzle 27 that communicates with the gas passage 31 is attached thereto. The nozzle 27 sprays the fuel gas vertically upward. When the fuel gas is ejected from the nozzle 27 to the throat 10, the fuel gas is taken up into the ambient air as the primary air and enters the throat, and a mixed gas of the fuel gas and the primary air is generated inside the throat 10 and the gas introduction chamber 16.

又,形成氣體導入室16上部之前述分隔壁11的下面係形成有朝喉部10的下游端開口***之***部32。***部32設於與喉部10的下游端開口相對應的區域,且其周圍形成有高低差33。Further, a lower portion of the partition wall 11 forming the upper portion of the gas introduction chamber 16 is formed with a bulging portion 32 which is raised toward the downstream end of the throat portion 10. The ridge portion 32 is provided in a region corresponding to the opening of the downstream end of the throat 10, and a height difference 33 is formed around the ridge portion 10.

在此,詳細說明主燃燒器用氣體供給通路25及中央燃燒器用氣體供給通路17。Here, the main burner gas supply passage 25 and the central burner gas supply passage 17 will be described in detail.

如第2圖所示,主燃燒器用氣體供給通路25形成於連結部24之內部,且其底面藉由與喉部一體的底板21而閉塞。且,氣體導入室16與主燃燒器分佈室22藉由主燃燒器用氣體供給通路25連通,將混合氣體供給至主燃燒器分佈室22。As shown in Fig. 2, the main burner gas supply passage 25 is formed inside the connecting portion 24, and the bottom surface thereof is closed by the bottom plate 21 integrated with the throat. Further, the gas introduction chamber 16 communicates with the main burner distribution chamber 22 via the main burner gas supply passage 25, and supplies the mixed gas to the main burner distribution chamber 22.

如第3圖所示,與喉部10一體的底板21係在主燃燒器用氣體供給通路25底部之位置形成凹部34,使混合空氣之流動剖面面積較大。又,位於與彼此相鄰之連結部24之間對應之位置的底板21形成有貫通孔35,使中央燃燒器9之燃燒用二次空氣可流動。而,如同於第4圖使燃燒頭2上下翻轉顯示,主燃燒器8的內面側形成有複數凸部36。如第3圖所示,這些凸部36會卡合於底板21所形成之複數卡合孔37。As shown in Fig. 3, the bottom plate 21 integrated with the throat 10 is formed with a recess 34 at a position at the bottom of the main burner gas supply passage 25, so that the flow cross-sectional area of the mixed air is large. Further, the bottom plate 21 located at a position corresponding to the connection portion 24 adjacent to each other is formed with a through hole 35 through which the secondary air for combustion of the center burner 9 can flow. On the other hand, as shown in Fig. 4, the burner head 2 is turned upside down, and a plurality of convex portions 36 are formed on the inner surface side of the main burner 8. As shown in FIG. 3, the convex portions 36 are engaged with the plurality of engaging holes 37 formed by the bottom plate 21.

且,如第4圖所示,彼此相鄰之主燃燒器用氣體供給通路25之間設有中央燃燒器用氣體供給通路17的入口。如第4圖和第5圖所示,中央燃燒器用氣體供給通路17之入口位於***部32外側。因此,中央燃燒器用空氣供給通路17之入口係位於與分隔壁11下面之喉部10下游端開口相對向之區域的外側。再者,中央燃燒器用氣體供給通路17入口附近形成有兩面構成之側面壁38而包圍該入口之一側。側面壁38位於較中央燃燒器用氣體供給通路17入口靠水平方向外側,且位於彼此相鄰之主燃燒器用氣體供給通路25之間。Further, as shown in Fig. 4, the inlet of the central burner gas supply passage 17 is provided between the main burner gas supply passages 25 adjacent to each other. As shown in FIGS. 4 and 5, the inlet of the central burner gas supply passage 17 is located outside the ridge portion 32. Therefore, the inlet of the central burner air supply passage 17 is located outside the region opposite to the opening at the downstream end of the throat 10 below the partition wall 11. Further, a side wall 38 having two sides is formed in the vicinity of the inlet of the gas supply passage 17 for the center burner to surround one side of the inlet. The side wall 38 is located on the outer side in the horizontal direction from the inlet of the central burner gas supply passage 17, and is located between the main burner gas supply passages 25 adjacent to each other.

依據上述構成,參照第2圖,當由噴嘴27朝向喉部10上游端開口噴射燃料氣體時,燃料氣體會一面自周圍捲入空氣做為一次空氣一面進入喉部10,生成燃料氣體與一次空氣混合之混合氣體。該混合氣體自喉部10下游端開口進入氣體導入室16,碰撞分隔壁11下面。碰撞到分隔壁11下面的混合氣體脫離喉部10上緣與分隔壁11下面之間後會沿分隔壁11下面散佈,形成朝主燃燒器用氣體供給通路25之氣流和朝中央燃燒器用氣體供給通路17之氣流。According to the above configuration, referring to Fig. 2, when the fuel gas is injected from the nozzle 27 toward the upstream end of the throat 10, the fuel gas is introduced into the throat 10 as air once, and the fuel gas and the primary air are generated. Mixed gas mixture. The mixed gas is opened from the downstream end of the throat 10 into the gas introduction chamber 16 to collide under the partition wall 11. The mixed gas that has collided under the partition wall 11 is separated from the upper edge of the throat 10 and the lower surface of the partition wall 11 and then spreads under the partition wall 11 to form a gas flow toward the main burner gas supply passage 25 and a gas supply passage toward the central burner. 17 airflow.

此時,由於在與喉部10下游端開口對應之領域之分隔壁11的下面設有***部32,因此混合氣體在改變為沿著***部32水平地擴散的氣流後,會因***部32外周之高低差33,被朝主燃燒器用氣體供給通路25及中央燃燒器用氣體供給通路17引導並順暢地流動。At this time, since the ridge portion 32 is provided on the lower surface of the partition wall 11 in the field corresponding to the opening of the downstream end of the throat portion 10, the mixed gas is changed to the airflow horizontally diffused along the ridge portion 32, and the ridge portion 32 is formed. The height difference 33 of the outer circumference is guided to the main burner gas supply passage 25 and the central burner gas supply passage 17 and smoothly flows.

朝向主燃燒器用氣體供給通路25之混合氣體會通過主燃燒器用氣體供給通路25進入主燃燒器8的主燃燒器分佈室22,並以均等分佈之狀態流向各焰孔23。The mixed gas that has flowed toward the main burner gas supply passage 25 enters the main combustor distribution chamber 22 of the main combustor 8 through the main combustor gas supply passage 25, and flows to the respective flame holes 23 in a state of being uniformly distributed.

另一方面,流向主燃燒器用氣體供給通路25以外的混合氣體會流向中央燃燒器用氣體供給通路17。如第4圖所示,中央燃燒器用氣體供給通路17之入口設於彼此相鄰之主燃燒器用氣體供給通路25之間。藉此,可各自分別形成朝中央燃燒器用氣體供給通路17之氣流和朝主燃燒器用氣體供給通路25之氣流。因此,朝向主燃燒器用氣體供給通路25之混合氣體氣流幾乎不會受朝中央燃燒器用氣體供給通路17之混合氣體氣流影響,可對主燃燒器8供給充分量之混合氣體。On the other hand, the mixed gas flowing out of the main burner gas supply passage 25 flows to the central burner gas supply passage 17. As shown in Fig. 4, the inlet of the central burner gas supply passage 17 is provided between the main burner gas supply passages 25 adjacent to each other. Thereby, the airflow toward the central burner gas supply passage 17 and the airflow toward the main burner gas supply passage 25 can be formed separately. Therefore, the mixed gas flow toward the main burner gas supply passage 25 is hardly affected by the mixed gas flow toward the central burner gas supply passage 17, and a sufficient amount of the mixed gas can be supplied to the main burner 8.

又,如第5圖所示,中央燃燒器用氣體供給通路17之入口位於與分隔壁11下面之喉部10下游端開口相對向之區域的外側,因此自喉部10下游端向上流動的混合氣體不會不改變其流動方向而直線地侵入中央燃燒器用氣體供給通路17,可防止過剩供給混合氣體至中央燃燒器9。Further, as shown in Fig. 5, the inlet of the gas supply passage 17 for the center burner is located outside the region opposite to the opening at the downstream end of the throat 10 below the partition wall 11, so that the mixed gas flows upward from the downstream end of the throat 10. The gas supply passage 17 for the central burner is not linearly changed without changing its flow direction, and excessive supply of the mixed gas to the central burner 9 can be prevented.

再者,如第5圖所示,朝向中央燃燒器用氣體供給通路17之混合氣體會碰撞側面壁38,因此流動方向被改變而確實地流入中央燃燒器用氣體供給通路17之入口。藉此,即使是以大火力燃燒而混合氣體流速較快時,足量的混合氣體仍會通過中央燃燒器用氣體供給通路17進入中央燃燒器9的中央燃燒器分佈室14,以均等分佈的狀態流向各焰孔15。Further, as shown in Fig. 5, the mixed gas toward the central burner gas supply passage 17 collides with the side wall 38, so that the flow direction is changed and surely flows into the inlet of the central burner gas supply passage 17. Thereby, even if the mixed gas flow rate is fast with a large fire power, a sufficient amount of the mixed gas enters the central burner distribution chamber 14 of the central burner 9 through the central burner gas supply passage 17 to be uniformly distributed. Flows to the respective flame holes 15.

而,本實施形態如第4圖所示,側面壁38雖以兩面構成,但側面壁38之形狀不限於此,舉例言之,亦可形成沿著中央燃燒器用氣體供給通路17彎曲之半圓形狀。In the present embodiment, as shown in Fig. 4, the side wall 38 is formed on both sides, but the shape of the side wall 38 is not limited thereto. For example, a semicircular shape curved along the central burner gas supply passage 17 may be formed. .

又,本實施形態中,雖顯示設有4個連結部24而具有4個主燃燒器用氣體供給通路25,但連結部24及主燃燒器用氣體供給通路25的數量不限於4個。惟,若考慮由氣體導入室16均勻地供給混合氣體到主燃燒器分佈室22,連結部24及主燃燒器用氣體供給通路25的數量宜設置複數個。In the present embodiment, the four main burner gas supply passages 25 are provided in the four connection portions 24, but the number of the connection portions 24 and the main burner gas supply passages 25 is not limited to four. However, in consideration of uniformly supplying the mixed gas to the main burner distribution chamber 22 from the gas introduction chamber 16, the number of the connection portion 24 and the main burner gas supply passage 25 is preferably plural.

又,本實施形態中,雖顯示於分隔壁下面設置***部32,藉此在***部32外周設有高低差33,但只要可充分獲得自氣體導入室16朝水平方向擴散的混合氣體氣流,不設***部32亦可。Further, in the present embodiment, the ridge portion 32 is provided on the lower surface of the partition wall, whereby the height difference 33 is provided on the outer circumference of the swell portion 32. However, as long as the mixed gas flow diffused from the gas introduction chamber 16 in the horizontal direction can be sufficiently obtained, The ridge portion 32 may not be provided.
