Description

【発明の属する技術分野】
本発明は、水素ガスの触媒による酸化反応熱を発生させる水素燃焼器の水素供給パイプに関する。
【０００２】
【従来の技術】
従来の水素燃焼器としては、水素ガスと空気の混合ガスを触媒に触れさせて酸化発熱させ、この熱を熱源として取り出すようになっており、水素ガスは空気流の供給通路に配置した水素供給パイプから噴出させて混合ガスを生成するようになったものがある（例えば、特許文献１参照。）。
【０００３】
この場合、水素供給パイプは空気流の供給通路の断面内を略直径方向に横切って配置され、その横切った部分に水素ガスを噴出させる水素噴出孔を形成してある。
【０００４】
【特許文献１】
特開２００２−１２２３１１号公報（第７頁、図１３，図１６）
【０００５】
【発明が解決しようとする課題】
しかしながら、かかる従来の水素燃焼器の水素供給パイプは、水素噴出孔から噴出した水素ガスが空気流と効率良く混ざり合うように、空気流の流速や流量等を考慮して水素噴出孔の数や形成位置が調整される。
【０００６】
このため、水素噴出孔の数や位置を含めた構造が複雑となり、そのシミュレーションや実験を繰り返し行って決定する必要があり、水素供給パイプの水素噴出部分の形成コストが嵩むことになる。
【０００７】
また、水素ガスを空気流中に効率良く混合するために、水素噴出孔を空気流に対向させる方向に形成してあり、これによって空気流の動圧に抗して水素ガスを噴出させる必要があるため、水素ガスの供給圧力を高めることになり、ひいては水素ガスの供給経路の気密構造の精度を高める必要が生ずる。
【０００８】
そこで、本発明はかかる従来の課題に鑑みて、空気流に対する水素噴出部分の配置方向に工夫を凝らすことにより、水素噴出孔の構成を簡単にし、かつ、水素ガスの供給圧力の低下を可能とする水素燃焼器の水素供給パイプを提供することを目的とする。
【０００９】
【課題を解決するための手段】
かかる目的を達成するために本発明の水素燃焼器の水素供給パイプにあっては、空気流の供給通路（３０）に水素供給パイプ（４０）を配置して、この水素供給パイプ（４０）から噴出する水素ガスを空気流中に混入して混合ガスを生成し、この混合ガスを混合器（１０）で更に撹拌した後に、下流側に配置した燃焼触媒で酸化反応させて発熱させるようにした水素燃焼器において、前記水素供給パイプ（４０）の先端部（４０ａ）に設けた水素噴出部分（４１）を、前記供給通路（３０）の側面側から内部に突設させ、前記供給通路（３０）の略中心部で空気流の流れ方向の上流側に指向して配置するとともに、この水素噴出部分（４１）に設ける水素噴出孔（４２）を空気流に対して略直角方向となる放射状に形成したことを特徴とする。
【００１０】
請求項２の発明は、請求項１記載の水素燃焼器の水素供給パイプにおいて、水素噴出部分（４１）の先端部にテーパ部分（４３）を形成したことを特徴とする。
【００１１】
請求項３の発明は、請求項１または２に記載の水素燃焼器の水素供給パイプにおいて、水素噴出部分を混合器の上流側に配置した状態で、水素供給パイプを混合器の内部に配置したことを特徴としている。
【００１２】
請求項４の発明は、請求項１ないし３に記載の水素供給パイプにおいて、水素噴出孔の孔径は水素供給パイプを流れる水素ガス流れに対し、流れ方向に設けられた水素噴出孔の径より流れに対抗する方向に設けられた噴出孔の径が大きいことを特徴としている。
【００１３】
【発明の効果】
このように構成した請求項１に記載の発明によれば、水素供給パイプの先端部に設けた水素噴出部分を、空気流の供給通路の略中心部で空気流の流れ方向に沿って配置したことにより、この水素噴出部分に設ける水素噴出孔を空気流に対して直角方向となる放射状に形成できるようになり、放射状の水素噴出孔から噴出した水素ガスを空気流と効率良く混合させることができる。
【００１４】
従って、水素噴出部分では複数の水素噴出孔を周方向に略等間隔をもって単に放射状に形成すればよく、水素噴出孔の構成を簡単にして水素噴出部分の形成コストを低廉化できるとともに、水素噴出孔は空気流に対して略直角となるため、この水素噴出孔に空気流の動圧が作用することがないため、水素ガスの供給圧力を低減して供給経路の構造を簡素化することができる。
【００１５】
請求項２に記載の発明によれば、請求項１の発明の効果に加えて、空気流の上流方向に指向させて配置した水素噴出部分の先端部にテーパ部分を形成したので、空気流はこのテーパ部分に沿って水素噴出部分を滑らかに流れるため、水素噴出孔の上流側で渦流発生を抑制でき、水素噴出孔から噴出した水素ガスと空気流とを効率良く混合させることができる。
【００１６】
請求項３に記載の発明によれば、請求項１，２の発明の効果に加えて、水素噴出部分を混合器の上流側に配置した状態で、水素供給パイプを混合器の内部に配置したことにより、水素供給パイプと混合器との間に設けられる間隔を無くすことができるため、水素燃焼器の全体長を短縮して装置全体を小型化することができる。
【００１７】
請求項４に記載の発明によれば、請求項１ないし３の発明に加えて、水素噴出孔の孔径は水素供給パイプを流れる水素ガス流れに対し、流れ方向に設けられた水素噴出孔の径より流れに対抗する方向に設けられた噴出孔の径を大きくしたことにより、水素流れの慣性力の働く方向の流出抵抗を大きくし、慣性力の働かない側の流出抵抗を小さくしたので水素噴出孔から水素ガスを均等に噴出できる。
【００１８】
【発明の実施の形態】
以下、本発明の実施形態を添付図面を参照して詳細に説明する。
【００１９】
（第１実施形態）
図１〜図５は本発明の第１実施形態を示す水素燃焼器の水素供給パイプで、図１は水素燃焼器の水素供給パイプから電気加熱触媒に至る要部を示す断面図、図２は混合器および電気加熱触媒を透視図法で示す斜視図、図３は電気加熱触媒の斜視図、図４は水素供給パイプの水素供給部分を示す断面図、図５は図４中Ａ−Ａ線に沿った断面図である。
【００２０】
水素燃焼器は、水素ガスを燃料として燃焼熱を発生させる装置であり、水素供給源（圧縮水素タンク）から供給される水素ガスと送風機からの空気とを、図１，図２に示すように混合器１０で均一な混合ガスとし、これを電気加熱触媒２０で加熱燃焼した際に発生する燃焼ガスを、この電気加熱触媒２０の下流側に配置した図外の燃焼触媒に送って、この燃焼触媒を触媒反応に十分な温度に加熱するようになっている。
【００２１】
そして、十分に加熱された燃焼触媒で更に混合ガスを酸化反応させて高熱の燃焼ガスを発生し、この燃焼ガスを図外の熱交換器に通して熱交換媒体（純水）と熱交換し、この熱交換媒体によって燃焼媒体で発生する燃焼熱を取り出すようになっている。（特開２００２−１２２３１１号公報参照）
前記混合器１０は、図１，図２に示すように水素ガスと空気の混合ガスが導入される空気流の供給通路としての円筒状のケーシング３０内に、複数（本実施形態では３枚）の第１，第２，第３混合板１１，１２，１３を、それぞれの面方向がケーシング１の中心軸と直角を成すように配置しつつ、各混合板１１，１２，１３間に適宜間隔を設けて取り付けることにより構成してある。
【００２２】
図２に示すように、混合ガスの導入方向に対して最上流側（図中左側）に配置した第１混合板１１は、中央部に大径Ｄ１の開口部１１ａを設けたドーナツ形状に形成するとともに、中間部に配置した第２混合板１２は周囲に４個の中径Ｄ２の開口部１２ａを設けて形成し、そして、最下流側（図中右側）に配置した第３混合板１３は小径Ｄ３の開口部１３ａを多数（本実施形態では１８個）設けて形成してある。例えば、ケーシング３０の内径５７．５ｍｍに対して、Ｄ１は３５ｍｍ、Ｄ２は１９ｍｍ、Ｄ３は９ｍｍとする。
【００２３】
そして、図中左方から流入した混合ガスは、第１混合板１１の開口部１１ａを通過した後、第２混合板１２の開口部１２ａで分流され、更に第３混合板１３の開口部１３ａによって細分流される間に、混合ガスは攪拌されて水素ガスと酸素とがむら無く混合されて電気加熱触媒２０に供給される。
【００２４】
電気加熱触媒２０は、図３に示すように白金（Ｐｔ）１％、残部アルミナ（Ａｌ２Ｏ３）からなる触媒を担持した平板２１と波板２２を重ねて巻回して、複数箇所をロー付けした後にケーシング３０に圧入して構成し、平板２１と波板２２との間に混合ガスを通過させる多数のセル２３を形成してある。
【００２５】
そして、電気加熱触媒２０の中心部に一方の電極２４を取り付けるとともに、外周部に他方の電極２５を取り付け、これら両電極２４，２５間に電流を印加することにより、電気加熱触媒２０を発熱させるようになっている。
【００２６】
一方の電極２４は、図２に示すように電気加熱触媒２０から混合ガスの導入方向（図中左方）に一旦延設した後に、その先端部を絶縁部材２６を介してケーシング３０の外方へと取り出してあり、また、他方の電極２５は、絶縁部材２７を介してケーシング３０の外方へと取り出してある。
【００２７】
ここで、この第１実施形態ではケーシング３０の混合器１０を経て電気加熱触媒２０に供給する混合ガスを生成するために、図１に示すように混合器１０の上流側に間隔Ｓを設けて、水素ガスをケーシング３０の空気流中に噴出する水素供給パイプ４０を配置するようになっている。
【００２８】
水素供給パイプ４０の先端部４０ａには、図４にも示すように先端を閉塞板４１ａによって閉止した円筒状の水素噴出部分４１を密接嵌合して固定してあり、この水素噴出部分４１に複数の水素噴出孔４２を形成することにより構成してある。
【００２９】
水素供給パイプ４０は、ケーシング３０の下方から内方へと径方向に挿入し、その挿入した先端部４０ａ近傍を空気流の上流側に湾曲させつつ略直角に折曲することにより、水素噴出部分４１をケーシング３０の略中心部に位置させるとともに、空気流の流れ方向（図中左右方向）に沿うように配置してある。
【００３０】
また、前記水素噴出孔４２は、図５に示すように円筒状の水素噴出部分４１の外周に等間隔をもって４箇所設けることにより、これら水素噴出孔４２が空気流に対して略直角方向となる放射状を成す。水素噴出孔４２は上方が小さく、下方が大きくなっている。
【００３１】
そして、図外の水素供給源から水素供給パイプ４０を介して水素噴出部分４１に供給された水素ガスは、水素噴出孔４２からケーシング３０の空気流中に噴出されて混合ガスとなり、この混合ガスを混合器１０によって更にむら無く混合した後に電気加熱触媒２０に供給するようになっている。
【００３２】
以上の構成によりこの第１実施形態の水素燃焼器にあっては、水素供給パイプ４０の先端部４０ａに設けた水素噴出部分４１を、ケーシング３０の略中心部で空気流の流れ方向に沿って配置するとともに、この水素噴出部分４１の外周に設けた水素噴出孔４２を空気流に対して直角方向となる放射状に形成したので、水素噴出孔４２から水素ガスを空気流中に放射状に噴出させることができるため、水素ガスと空気とを効率良く混合させることができる。
【００３３】
従って、水素噴出部分４１では複数の水素噴出孔４２を周方向に略等間隔をもって単に放射状に形成すればよく、水素噴出孔４２の構成を簡単にして水素噴出部分４１の形成コストを低廉化できる。
【００３４】
また、水素噴出孔４２は空気流に対して略直角となるため、この水素噴出孔４２に空気流の動圧が作用することがないため、水素ガスを低圧によっても空気流中に噴射できるため、水素ガスの供給圧力を低減して供給経路の構造を簡素化することができる。
【００３５】
また、水素噴出孔４２は、水素ガス流れ方向に相当する水素噴出部分４１の上方が小さく下方が大きくなっているため、水素供給パイプ４０を流れて水素噴出部分４１に流入した水素ガスは慣性力により上方の水素噴出孔４２に下方の水素噴出孔４２より多くの圧力がかかるが、下方の水素噴出孔４２の孔径が大きいので水素ガスが噴出しやすいため、水素噴出孔４２全体から水素ガスを均等に噴出できる。
【００３６】
（第２実施形態）
図６は本発明の第２実施形態を示し、前記第１実施形態と同一構成部分に同一符号を付して重複する説明を省略して述べる。
【００３７】
図６は水素供給パイプの水素供給部分を示す断面図で、この第２実施形態の水素供給パイプ４０は、水素噴出部分４１を空気流の上流方向に指向させて配置し、その先端部にテーパ部分４３を形成するようになっている。
【００３８】
従って、この第２実施形態にあっては、空気流はテーパ部分４３に沿って水素噴出部分４１を滑らかに流れるため、水素噴出孔４２の上流側で渦流発生を抑制でき、水素噴出孔４２から噴出した水素ガスと空気流とを効率良く混合させることができる。
【００３９】
（第３実施形態）
図７は本発明の第３実施形態を示し、前記第１実施形態と同一構成部分に同一符号を付して重複する説明を省略して述べる。

【００４１】
勿論、この第３実施形態にあっても、水素噴出部４１の外周に等間隔をもって水素噴出孔４２を４箇所設け、これら水素噴出孔４２が空気流に対して略直角方向となる放射状を成している。

（第４実施形態）
図８は本発明の第４実施形態を示し、前記第１実施形態と同一構成部分に同一符号を付して重複する説明を省略して述べる。

【００４４】
即ち、この第４実施形態では水素供給パイプ４０を、第１混合板１１と第２混合板１２との間に配置し、水素噴出部分４１を第１混合板１１の開口部１１ａ（図２参照）を通して空気流の上流側に配置するようになっている。
【００４５】
従って、この第４実施形態にあっては、水素供給パイプ４０を混合器１０の内部に配置したことにより、水素供給パイプ４０と混合器１０との間に設けられる間隔Ｓ（図１参照）を無くすことができるため、水素燃焼器の全体長を短縮して装置全体を小型化することができる。
【００４６】
勿論、この第４実施形態では水素供給パイプ４０を混合器１０の内部に配置した場合にも、水素噴出部分４１を混合器１０の上流側に配置してあるので、混合器１０の上流側で混合ガスを生成できるため、混合器１０による混合ガスの攪拌機能を十分に享受することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a hydrogen supply pipe of a hydrogen combustor that generates heat of oxidation reaction by a catalyst of hydrogen gas.
[0002]
[Prior art]
As a conventional hydrogen combustor, a mixed gas of hydrogen gas and air is brought into contact with a catalyst to generate heat of oxidation, and this heat is taken out as a heat source. Hydrogen gas is supplied to a hydrogen supply passage arranged in an air flow supply passage. There is one in which a mixed gas is generated by being ejected from a pipe (for example, see Patent Document 1).
[0003]
In this case, the hydrogen supply pipe is disposed across the cross section of the air flow supply passage in a substantially diametrical direction, and a hydrogen ejection hole for ejecting hydrogen gas is formed in the crossing portion.
[0004]
[Patent Document 1]
Japanese Patent Laid-Open No. 2002-12211 (Page 7, FIGS. 13 and 16)
[0005]
[Problems to be solved by the invention]
However, the hydrogen supply pipe of such a conventional hydrogen combustor has the number of hydrogen ejection holes and the number of hydrogen ejection holes in consideration of the flow velocity and flow rate of the air flow so that the hydrogen gas ejected from the hydrogen ejection holes is efficiently mixed with the air flow. The formation position is adjusted.
[0006]
For this reason, the structure including the number and positions of the hydrogen ejection holes becomes complicated, and it is necessary to repeat the simulation and experiment to determine the structure, which increases the cost of forming the hydrogen ejection portion of the hydrogen supply pipe.
[0007]
Further, in order to efficiently mix the hydrogen gas into the air flow, the hydrogen ejection holes are formed in the direction facing the air flow, and thus it is necessary to eject the hydrogen gas against the dynamic pressure of the air flow. For this reason, the supply pressure of the hydrogen gas is increased, and as a result, it is necessary to improve the accuracy of the airtight structure of the supply path of the hydrogen gas.
[0008]
Therefore, in view of such conventional problems, the present invention makes it possible to simplify the configuration of the hydrogen ejection holes and reduce the supply pressure of hydrogen gas by devising the arrangement direction of the hydrogen ejection portion with respect to the air flow. An object of the present invention is to provide a hydrogen supply pipe for a hydrogen combustor.
[0009]
[Means for Solving the Problems]
In order to achieve this object, in the hydrogen supply pipe of the hydrogen combustor of the present invention, a hydrogen supply pipe (40) is disposed in the supply path (30) of the air flow, and the hydrogen supply pipe (40) The hydrogen gas to be ejected is mixed into the air flow to generate a mixed gas, and this mixed gas is further stirred in the mixer (10), and then is oxidized by a combustion catalyst arranged on the downstream side to generate heat. In the hydrogen combustor, a hydrogen ejection portion (41) provided at a tip portion (40a) of the hydrogen supply pipe (40) is projected from the side surface side of the supply passage (30) to the inside, and the supply passage (30 ) In the center of the air flow direction upstream of the flow direction of the air flow, and the hydrogen jet holes (42) provided in the hydrogen jet portion (41) are arranged radially in a direction substantially perpendicular to the air flow. Characterized by the formation
[0010]
The invention of claim 2 is the hydrogen supply pipe of the hydrogen combustor according to claim 1, characterized in that a tapered portion (43) first end portion of the hydrogen ejecting portion (41).
[0011]
According to a third aspect of the present invention, in the hydrogen supply pipe of the hydrogen combustor according to the first or second aspect, the hydrogen supply pipe is disposed inside the mixer in a state where the hydrogen ejection portion is disposed upstream of the mixer. It is characterized by that.
[0012]
According to a fourth aspect of the present invention, in the hydrogen supply pipe according to any one of the first to third aspects, the diameter of the hydrogen ejection hole is larger than the diameter of the hydrogen ejection hole provided in the flow direction with respect to the hydrogen gas flow flowing through the hydrogen supply pipe. The diameter of the ejection hole provided in the direction which opposes is large.
[0013]
【The invention's effect】
According to the invention described in claim 1 configured as described above, the hydrogen ejection portion provided at the tip of the hydrogen supply pipe is arranged along the air flow direction in the substantially central portion of the air flow supply passage. As a result, the hydrogen ejection holes provided in the hydrogen ejection portion can be formed in a radial direction perpendicular to the air flow, and the hydrogen gas ejected from the radial hydrogen ejection holes can be efficiently mixed with the air flow. it can.
[0014]
Therefore, it is only necessary to form a plurality of hydrogen ejection holes radially at substantially equal intervals in the circumferential direction at the hydrogen ejection part, thereby simplifying the configuration of the hydrogen ejection holes and reducing the formation cost of the hydrogen ejection part. Since the holes are substantially perpendicular to the air flow, the dynamic pressure of the air flow does not act on the hydrogen ejection holes, so that the supply pressure of the hydrogen gas can be reduced and the structure of the supply path can be simplified. it can.
[0015]
According to the second aspect of the present invention, in addition to the effect of the first aspect of the invention, since the tapered portion is formed at the tip of the hydrogen ejection portion arranged in the upstream direction of the air flow, the air flow is Since the hydrogen ejection portion flows smoothly along the taper portion, vortex generation can be suppressed on the upstream side of the hydrogen ejection hole, and the hydrogen gas ejected from the hydrogen ejection hole and the air stream can be mixed efficiently.
[0016]
According to the invention described in claim 3, in addition to the effects of the inventions of claims 1 and 2, the hydrogen supply pipe is arranged inside the mixer in a state where the hydrogen ejection portion is arranged on the upstream side of the mixer. As a result, the space provided between the hydrogen supply pipe and the mixer can be eliminated, so that the entire length of the hydrogen combustor can be shortened and the entire apparatus can be downsized.
[0017]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0019]
(First embodiment)
1 to 5 are hydrogen supply pipes of the hydrogen combustor showing the first embodiment of the present invention, FIG. 1 is a cross-sectional view showing the main part from the hydrogen supply pipe of the hydrogen combustor to the electric heating catalyst, and FIG. FIG. 3 is a perspective view of the electric heating catalyst, FIG. 4 is a cross-sectional view showing the hydrogen supply portion of the hydrogen supply pipe, and FIG. 5 is taken along line AA in FIG. FIG.
[0020]
A hydrogen combustor is a device that generates combustion heat using hydrogen gas as a fuel. As shown in FIGS. 1 and 2, hydrogen gas supplied from a hydrogen supply source (compressed hydrogen tank) and air from a blower are used. A uniform mixed gas is produced by the mixer 10, and the combustion gas generated when this is heated and burned by the electric heating catalyst 20 is sent to a combustion catalyst (not shown) disposed downstream of the electric heating catalyst 20, and this combustion is performed. The catalyst is heated to a temperature sufficient for the catalytic reaction.
[0021]
Then, the mixed gas is further oxidized with a sufficiently heated combustion catalyst to generate a high-temperature combustion gas, and this combustion gas is passed through a heat exchanger (not shown) to exchange heat with a heat exchange medium (pure water). The heat of combustion generated in the combustion medium is taken out by this heat exchange medium. (See JP 2002-12211 A)
As shown in FIGS. 1 and 2, a plurality of the mixers 10 (three in this embodiment) are provided in a cylindrical casing 30 as an air flow supply passage through which a mixed gas of hydrogen gas and air is introduced. The first, second, and third mixing plates 11, 12, and 13 are arranged at appropriate intervals between the mixing plates 11, 12, and 13, while their surface directions are perpendicular to the central axis of the casing 1. It is comprised by providing and attaching.
[0022]
As shown in FIG. 2, the first mixing plate 11 disposed on the most upstream side (left side in the figure) with respect to the introduction direction of the mixed gas is formed in a donut shape having an opening 11 a having a large diameter D <b> 1 at the center. At the same time, the second mixing plate 12 disposed in the middle part is formed by providing four openings 12a having a medium diameter D2 around the third mixing plate 13 disposed on the most downstream side (right side in the figure). Is formed by providing a large number (18 in this embodiment) of openings 13a having a small diameter D3. For example, with respect to the inner diameter of the casing 30 of 57.5 mm, D1 is 35 mm, D2 is 19 mm, and D3 is 9 mm.
[0023]
And the mixed gas which flowed in from the left in the figure passes through the opening 11a of the first mixing plate 11, and then is diverted by the opening 12a of the second mixing plate 12, and further, the opening 13a of the third mixing plate 13. While the gas is subdivided by the above, the mixed gas is stirred and the hydrogen gas and oxygen are mixed evenly and supplied to the electric heating catalyst 20.
[0024]
Electrically heated catalyst 20, platinum (Pt) 1% as shown in FIG. 3, by winding superposed the remainder alumina (Al 2 O 3) plate-21 catalyst carrying consisting and corrugated 22, row a plurality of locations A plurality of cells 23 are formed between the flat plate 21 and the corrugated plate 22 and allow the mixed gas to pass therethrough.
[0025]
And while attaching one electrode 24 to the center part of the electric heating catalyst 20, attaching the other electrode 25 to an outer peripheral part, and applying an electric current between these both electrodes 24 and 25, the electric heating catalyst 20 is made to generate heat. It is like that.
[0026]
As shown in FIG. 2, one electrode 24 is once extended from the electric heating catalyst 20 in the mixed gas introduction direction (left side in the figure), and then its tip end is disposed outside the casing 30 via the insulating member 26. The other electrode 25 is taken out of the casing 30 through an insulating member 27.
[0027]
Here, in the first embodiment, in order to generate a mixed gas to be supplied to the electric heating catalyst 20 through the mixer 10 of the casing 30, an interval S is provided on the upstream side of the mixer 10 as shown in FIG. A hydrogen supply pipe 40 for ejecting hydrogen gas into the air flow of the casing 30 is arranged.
[0028]
As shown in FIG. 4, a cylindrical hydrogen ejection portion 41 having a distal end closed by a closing plate 41 a is closely fitted and fixed to the distal end portion 40 a of the hydrogen supply pipe 40. A plurality of hydrogen ejection holes 42 are formed.
[0029]
The hydrogen supply pipe 40 is inserted into the casing 30 in the radial direction from the bottom to the inside, and the vicinity of the inserted tip 40a is bent toward the upstream side of the air flow while being bent at a substantially right angle, whereby a hydrogen ejection portion 41 is positioned substantially at the center of the casing 30 and is arranged along the air flow direction (left and right direction in the figure).
[0030]
Further, as shown in FIG. 5, the hydrogen ejection holes 42 are provided at four positions on the outer periphery of the cylindrical hydrogen ejection portion 41 at equal intervals, so that the hydrogen ejection holes 42 are substantially perpendicular to the air flow. Radial. The upper part of the hydrogen ejection hole 42 is small and the lower part is large.
[0031]
Then, the hydrogen gas supplied from the hydrogen supply source (not shown) to the hydrogen ejection portion 41 via the hydrogen supply pipe 40 is ejected from the hydrogen ejection hole 42 into the air flow of the casing 30 to become a mixed gas. Is further uniformly mixed by the mixer 10 and then supplied to the electric heating catalyst 20.
[0032]
With the above configuration, in the hydrogen combustor according to the first embodiment, the hydrogen ejection portion 41 provided at the distal end portion 40a of the hydrogen supply pipe 40 is arranged at the substantially central portion of the casing 30 along the air flow direction. Since the hydrogen ejection holes 42 provided on the outer periphery of the hydrogen ejection portion 41 are radially formed in a direction perpendicular to the airflow, hydrogen gas is ejected radially from the hydrogen ejection holes 42 into the airflow. Therefore, hydrogen gas and air can be mixed efficiently.
[0033]
Accordingly, in the hydrogen ejection portion 41, the plurality of hydrogen ejection holes 42 may be simply formed radially at substantially equal intervals in the circumferential direction, and the configuration of the hydrogen ejection holes 42 can be simplified and the formation cost of the hydrogen ejection portion 41 can be reduced. .
[0034]
Further, since the hydrogen ejection hole 42 is substantially perpendicular to the air flow, the dynamic pressure of the air flow does not act on the hydrogen ejection hole 42, and therefore hydrogen gas can be injected into the air flow even at a low pressure. In addition, the supply pressure of hydrogen gas can be reduced to simplify the structure of the supply path.
[0035]
Moreover, since the upper part of the hydrogen ejection part 41 corresponding to the hydrogen gas flow direction is small and the lower part of the hydrogen ejection hole 42 is large, the hydrogen gas flowing through the hydrogen supply pipe 40 and flowing into the hydrogen ejection part 41 has an inertial force. As a result, more pressure is applied to the upper hydrogen ejection hole 42 than the lower hydrogen ejection hole 42, but since the diameter of the lower hydrogen ejection hole 42 is large, hydrogen gas is easily ejected. Can be ejected evenly.

A portion 43 is formed.
[0038]
Therefore, in this second embodiment, the air flow smoothly flows through the hydrogen ejection portion 41 along the taper portion 43, so that vortex generation can be suppressed on the upstream side of the hydrogen ejection hole 42. The ejected hydrogen gas and the air flow can be mixed efficiently.
[0039]
