図５、図６、図７は、従来のボイラ本体断面図で、図中31はバーナ、32はボイ ラ水、33は燃焼筒、34は熱交換筒、37は整流筒、38は外枠、39は燃焼室、40は煙 突接続口、44は煙管、45は給水口、46は出湯口を示す。 Figures 5, 6, and 7 are cross-sectional views of the main body of a conventional boiler, where 31 is a burner and 32 is a boiler. 33 is the combustion tube, 34 is the heat exchange tube, 37 is the rectifier tube, 38 is the outer frame, 39 is the combustion chamber, 40 is the smoke 44 is a smoke pipe, 45 is a water supply port, and 46 is a hot water outlet.
【０００３】 従来のボイラ本体構造、例えば図５に示す現在のボイラの主流をしめる炉筒煙 管式の場合は、燃焼筒33上部から複数の煙管44が水密性・気密性良く溶接接続さ れて延在し、燃焼筒33および煙室44と外枠38の間はボイラ水32で満たされている 。オイルまたはガスなどをバーナ31により燃焼室39で燃焼させて生ずる高温の燃 焼ガスは、燃焼筒33および煙管44でボイラ水32と熱交換してボイラ水の温度を上 昇させ、燃焼ガスは同図の矢印方向に進んで煙突接続口40へ送られ、そこから図 示しない煙突を経て排出される。ボイラ水32は順次外枠38の下部に設けられた給 水口45から供給され、熱交換されたボイラ水は上部の出湯口46から送り出される 。0003 Conventional boiler body structure, for example, the furnace smoke that forms the main stream of the current boiler shown in Figure 5. In the case of the pipe type, multiple smoke pipes 44 are welded together from the top of the combustion tube 33 with good watertightness and airtightness. The space between the combustion tube 33 and the smoke chamber 44 and the outer frame 38 is filled with boiler water 32. . High-temperature combustion produced by burning oil or gas in the combustion chamber 39 by the burner 31 The burnt gas exchanges heat with the boiler water 32 in the combustion tube 33 and smoke pipe 44 to raise the temperature of the boiler water. The combustion gas moves in the direction of the arrow in the same figure and is sent to the chimney connection port 40, from where it goes in the direction of the arrow in the figure. It is discharged through a chimney not shown. The boiler water 32 is sequentially supplied to the water supply provided at the bottom of the outer frame 38. The boiler water supplied from the water port 45 and subjected to heat exchange is sent out from the upper outlet 46. .
【０００４】 この炉筒煙管式は、燃焼筒33に複数の煙管44が接続されているので熱交換効率 は優れているが、ボイラ本体構造が複雑なため水密性・気密性を要求される溶接 部分が多く、制作に高度の技術を要し、またコストが高くなる。0004 This furnace tube and smoke tube type has multiple smoke tubes 44 connected to the combustion tube 33, which improves heat exchange efficiency. However, due to the complicated structure of the boiler body, welding requires watertightness and airtightness. It has many parts, requires advanced technology to produce, and is expensive.
【０００５】 図６に示す単筒式は、燃焼筒33と熱交換筒34とを一体化することによってボイ ラ本体構造を簡素化し、溶接部分を少なくしてコストを安くできるが、煙突接続 口40から出る燃焼ガス温度は約 400℃程度と高く熱交換効率が悪いことを示す。 さらに、整流筒37のＢで示す底部はボイラ水で冷却されないので、燃焼室39内の 火炎輻射を受けて高温となるため高い耐熱性を備えたものでないと耐久性が悪く なる。[0005] The single cylinder type shown in Fig. 6 has a combustion tube 33 and a heat exchange tube 34 integrated into one body. It is possible to simplify the main body structure and reduce the cost by reducing the number of welded parts, but the chimney connection The temperature of the combustion gas coming out of the port 40 is as high as about 400°C, indicating poor heat exchange efficiency. Furthermore, since the bottom part of the rectifier tube 37 indicated by B is not cooled by boiler water, the inside of the combustion chamber 39 Durability will be poor unless it has high heat resistance as it becomes high temperature when exposed to flame radiation. Become.
【０００６】 そこで単筒式の改良型として図７に示す如く、整流筒37のＢ部分に火炎輻射を 直接受けないよう燃焼筒33と熱交換筒34をＣ部分で絞ってボイラ水の水冷壁を作 り過熱を抑えるが、逆にＣ部分を絞るために構造が複雑化してコストが高くなる 。[0006] Therefore, as an improved version of the single cylinder type, as shown in Fig. 7, flame radiation is applied to the B part of the rectifier tube 37. Create a water-cooled wall for the boiler water by constricting the combustion tube 33 and heat exchange tube 34 at part C to avoid direct contact with the boiler water. This suppresses overheating, but conversely, constricting the C portion complicates the structure and increases cost. .
【０００７】 従来型のボイラ本体は共通して燃焼筒33上に熱交換筒34または煙管44を配する ので縦方向に長くなり易いが、ボイラの設置場所やメンテナンスの都合でそれほ ど高くできず、またバーナ31を図７に示されるように横方向から燃焼させる場合 が多い。このため、図５ないし図７に示す如く、燃焼室39は燃焼に必要な容積を 確保する必要から高さＬ2 を抑えて径Ｄ2 を比較的大きくとり、Ｌ2 ／Ｄ2 を１ 〜1.5 程度とした。しかし、径Ｄ2 が大きくなればなるほど外からの水圧に弱く なり、燃焼室のボイラ水に対する耐圧力を増すため、バルジと称するひだを燃焼 筒につけて補強したり、筒自体の肉厚を増すことなどが行われる。[0007] Conventional boiler bodies commonly have a heat exchange tube 34 or a smoke tube 44 arranged on the combustion tube 33, so they tend to be long in the vertical direction, but due to the boiler installation location and maintenance considerations, it cannot be made that tall. Further, in many cases, the burner 31 is used to cause combustion from the side, as shown in FIG. For this reason, as shown in FIGS. 5 to 7, the height L 2 of the combustion chamber 39 is suppressed and the diameter D 2 is made relatively large, in order to ensure the volume necessary for combustion, and L 2 /D 2 is set to 1 to 7. It was set at around 1.5. However, the larger the diameter D2 , the weaker it becomes against external water pressure, and in order to increase the pressure resistance of the combustion chamber against boiler water, the combustion tube is reinforced with folds called bulges, and the thickness of the tube itself is increased. things are done.
【０００８】[0008]
上記した如く、従来のボイラ本体構造は炉筒煙管式、単筒式およびその改良型 などにみられるように、熱交換部分の伝熱面積を広くとって熱交換効率を上げよ うとすると構造が複雑化してコストが高くなり、逆に単筒式のように単純な構造 でコストを安くしようとすると熱交換効率が悪くなる問題があった。このように ボイラ本体構造において、製造コストの低減と熱交換効率の向上という相反する 要請を両立させることが容易でないのが現状である。 As mentioned above, the conventional boiler body structures are the furnace and smoke tube type, the monotube type, and their improved types. As can be seen in If you try to do this, the structure will become complicated and the cost will increase; When trying to reduce the cost, there was a problem that the heat exchange efficiency deteriorated. in this way In the boiler body structure, reducing manufacturing costs and improving heat exchange efficiency are contradictory. The current situation is that it is not easy to balance these demands.
【０００９】 また、従来型ボイラの燃焼室39は、高さＬ2 に比べて径Ｄ2 を大きくとる必要 から (従来はL2／D2＝１〜1.5)ボイラ水の水圧に対する耐圧力を増すためバルジ を入れたり、燃焼筒の肉厚を増すことが行われ、そうするとコストがかさむとい う問題がある。Furthermore, since the combustion chamber 39 of the conventional boiler needs to have a diameter D 2 larger than the height L 2 (conventionally, L 2 /D 2 = 1 to 1.5), the pressure resistance against the water pressure of the boiler water has to be increased. To increase this, a bulge is inserted or the thickness of the combustion tube is increased, which raises the problem of increased costs.
【００１０】 本考案は上記問題点に鑑みて創作されたもので、耐圧力を有し、熱交換効率が 高く、構造が簡単で製造コストの安いボイラ本体構造を提供することを目的とす る。0010 This invention was created in view of the above problems, and has pressure resistance and heat exchange efficiency. The purpose is to provide a boiler body structure that is high, simple in structure, and low in manufacturing cost. Ru.

本考案のボイラ本体構造は、燃焼筒13にバーナ11を燃焼室の軸方向に取り付け 、さらに燃焼筒13と熱交換筒14とを独立させることによって、燃焼筒13および熱 交換筒14の (筒の長さ)/ (筒の径) を４〜６と小径化できるため簡単で圧力に強 い構造が得られ、コストを低減することができ、燃焼室13と熱交換筒14を別個に してその間を連絡路15で連結させるので、整流筒17は直接火炎幅射を受けず、こ のため整流筒に耐熱処理を施す必要がなく低コストにでき、熱交換筒14内の整流 筒17は、着脱可能に装着されているためメンテナンス等が容易に行え、整流筒17 に螺施状に整流板16を配設することにより、燃焼ガスが筒抜けにならずに熱交換 壁で効率よく熱交換がなされる。 The boiler body structure of this invention has a burner 11 attached to the combustion tube 13 in the axial direction of the combustion chamber. Furthermore, by making the combustion tube 13 and the heat exchange tube 14 independent, the combustion tube 13 and the heat exchange tube 14 are separated. The replacement tube 14 can be easily and resistant to pressure because the (tube length)/(tube diameter) can be reduced to 4 to 6. The combustion chamber 13 and the heat exchange tube 14 can be separated into a new structure and cost can be reduced. Since the connecting passage 15 connects them, the rectifier tube 17 is not directly exposed to flame radiation. Therefore, there is no need to perform heat-resistant treatment on the rectifier tube, which reduces costs. Since the tube 17 is removably installed, maintenance etc. can be easily performed. By arranging the straightening plate 16 in a screw shape, heat exchange is possible without burning gas leaking through the cylinder. Heat is exchanged efficiently through the walls.

以下、図面を参照して本考案の実施例を詳細に説明する。 図１は本考案実施例のボイラ本体縦断面図、図２は整流筒の部分断面図、図３ は図１のＡ−Ａ′線断面図、図４は本考案実施例の平面図である。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Figure 1 is a vertical sectional view of the boiler main body according to the embodiment of the present invention, Figure 2 is a partial sectional view of the rectifier tube, and Figure 3. 1 is a sectional view taken along line A-A' in FIG. 1, and FIG. 4 is a plan view of an embodiment of the present invention.
【００１４】 本考案は、上記問題点を解決するため図１ないし図４に示す如く、バーナ11の 燃焼熱を熱媒体12と熱交換させるボイラ本体構造において、バーナ11を燃焼室の 軸方向に取り付けた燃焼筒13、燃焼筒13と独立し燃焼筒13からの燃焼ガスを熱交 換させる１個の熱交換筒14、燃焼筒13と熱交換筒14間を連絡する連絡路15を備え 、熱交換筒14内には外側に螺旋状に整流板16を配設し内部に断熱材24をつめた着 脱可能な整流筒17が装着された構成となる。バーナ11は、ボイラの熱源となる燃 焼手段であり、例えばオイルバーナやガスバーナなどを好ましく用いることがで きる。熱媒体12は、ボイラ水として水が一般に用いられる。[0014] In order to solve the above-mentioned problems, the present invention has developed a burner 11 as shown in FIGS. 1 to 4. In the boiler body structure that exchanges combustion heat with heat medium 12, burner 11 is placed in the combustion chamber. The combustion tube 13 installed in the axial direction is independent of the combustion tube 13 and heat exchanges the combustion gas from the combustion tube 13. It is equipped with one heat exchange cylinder 14 for exchanging heat, and a communication path 15 for communicating between the combustion cylinder 13 and the heat exchange cylinder 14. In the heat exchange tube 14, a straightening plate 16 is arranged spirally on the outside and a heat insulating material 24 is packed inside. It has a configuration in which a removable rectifier tube 17 is attached. Burner 11 is a fuel that is the heat source for the boiler. For example, an oil burner or a gas burner can be preferably used. Wear. Water is generally used as the heat medium 12 as boiler water.
【００１５】 燃焼筒13は、バーナ11に連結された筒状容器でこの中の空間が燃焼室19となっ ている。燃焼筒13はボイラ水の水圧を受けるため耐圧構造の円筒形またはこれに 類する構造にする。バーナ11を燃焼室の軸方向に取り付けるとは、円筒形または これに類する形状の燃焼室の軸と同方向 (円筒形であれば筒方向) にバーナの吹 き出し口を取り付けることをいう。細長い炎を形成することによって燃焼室の径 を小さくできる。[0015] The combustion tube 13 is a cylindrical container connected to the burner 11, and the space inside thereof serves as a combustion chamber 19. ing. The combustion tube 13 is cylindrical or has a pressure-resistant structure to receive the water pressure of boiler water. Create a similar structure. Installing the burner 11 in the axial direction of the combustion chamber means cylindrical or The burner blows in the same direction as the axis of a combustion chamber with a similar shape (in the direction of the cylinder if it is cylindrical). Refers to installing an outlet. The diameter of the combustion chamber by forming an elongated flame can be made smaller.
【００１６】 熱交換筒14は、燃焼筒13からの燃焼ガスの熱を熱媒体12と熱交換させる筒で、 燃焼筒13から独立した筒構造となっている。この熱交換筒内には着脱可能に整流 筒17が装着され、整流筒17は、燃焼ガスが熱交換部分、すなわち整流筒17と熱交 換筒14の間の部分を素通りしないように、外側に螺旋状に整流板16を配設して燃 焼ガスを効率良く熱交換させる。すなわち、螺旋状に設けられた整流板16に沿っ て燃焼ガスが回転しつつ上昇することによって遠心力が働き、燃焼ガスが熱交換 筒14になめるように接触するため、この面の熱伝達が良くなり熱交換を高効率化 する。[0016] The heat exchange tube 14 is a tube that exchanges heat of combustion gas from the combustion tube 13 with the heat medium 12. It has a cylinder structure independent from the combustion cylinder 13. This heat exchange cylinder has a removable rectifier. The cylinder 17 is installed, and the rectifier cylinder 17 allows the combustion gas to exchange heat with the heat exchange part, that is, the rectifier cylinder 17. A current plate 16 is arranged spirally on the outside to prevent the combustion from passing through the area between the exchange tubes 14. To efficiently exchange heat of burning gas. That is, along the rectifier plate 16 provided in a spiral shape, As the combustion gas rotates and rises, centrifugal force acts, and the combustion gas exchanges heat. Since it comes into contact with the tube 14 in a licking manner, heat transfer on this surface improves, making heat exchange highly efficient. do.
【００１７】 整流筒17の好ましい構造例としては、図２に示されるようにその内部の全体に わたって保温材や断熱材を入れ、整流筒17が燃焼ガスの熱エネルギーを浪費する ことのないようにする。断熱材をこのように配置することによって整流筒17はそ の全体にわたってほぼ均一な温度に保たれ、整流板16に沿って上昇する燃焼ガス の流れが乱されることがなく、良好な熱交換が実現する。整流筒17と熱交換筒14 との隙間をできるだけ小さくし (例えば17mm程度) 、その隙間部分に整流板16を 螺旋状に配置する。整流板16は熱交換筒14内部の整流筒17に設けられるため、溶 接に水密性・気密性が要求されず加工が容易である。整流板16の螺旋のピッチ幅 は、燃焼ガスの冷却による体積の減少に応じて変化させ、ガスの流速を一定に保 つよう設計することが望ましい。整流板の螺旋は２重以上にすることができる。[0017] As a preferable example of the structure of the rectifier tube 17, as shown in FIG. By inserting heat insulating material or insulation material across the tube, the rectifying tube 17 wastes the thermal energy of the combustion gas. I'll make sure this doesn't happen. By arranging the heat insulating material in this way, the rectifier tube 17 The combustion gas is maintained at a nearly uniform temperature throughout the area and rises along the baffle plate 16. The flow of water is not disturbed and good heat exchange is achieved. Rectifier tube 17 and heat exchange tube 14 Make the gap between the Arrange in a spiral. Since the rectifying plate 16 is installed in the rectifying cylinder 17 inside the heat exchange cylinder 14, It is easy to process as it does not require watertightness or airtightness. Spiral pitch width of rectifier plate 16 is changed according to the decrease in volume due to combustion gas cooling, and the gas flow velocity is kept constant. It is desirable to design the The current plate may have two or more spirals.
【００１８】 本考案実施例のボイラ本体縦断面を示す図１において、例えばオイルを使用す るバーナ11を円筒形の燃焼室19の上から燃焼室の軸方向 (ここでは下方) に向け て設置する。個別の燃焼筒13および熱交換筒14はボイラ本体の外枠18内に円筒形 の筒を２本平行に立てるように配置され、外枠18との間は熱媒体 (ボイラ水)12 でみたされる。燃焼筒13および熱交換筒14間は、下部にて連絡路15で連絡され燃 焼ガスがここを通って熱交換筒14に運ばれる。[0018] In FIG. 1, which shows a vertical section of the boiler body according to an embodiment of the present invention, for example, if oil is used, The burner 11 is directed from above the cylindrical combustion chamber 19 in the axial direction of the combustion chamber (in this case, downward). and install it. Separate combustion tubes 13 and heat exchange tubes 14 are cylindrical within the outer frame 18 of the boiler body. Two cylinders are arranged in parallel, and a heat medium (boiler water) 12 is placed between the outer frame 18 and the outer frame 18. Filled with The combustion tube 13 and the heat exchange tube 14 are connected at the bottom by a communication passage 15, and the combustion The burnt gas is conveyed to the heat exchange tube 14 through this.
【００１９】 熱交換筒14内に装着される整流筒17は図２に示す如く、その上部に吊具21、蓋 22、把手23を付けて熱交換筒14に対する着脱を容易にし、内部に断熱材24を備え 、その表面にはこの場合２重の螺旋状に17mm幅の整流板16を点付接着する構成と した。これらの構成によるボイラ本体構造の動作を以下具体的に説明する。[0019] As shown in FIG. 2, the rectifier tube 17 installed inside the heat exchange tube 14 has a hanging tool 21 and a lid on its upper part. 22, a handle 23 is attached to facilitate attachment and detachment from the heat exchange tube 14, and a heat insulating material 24 is provided inside. In this case, a rectifying plate 16 with a width of 17 mm is dotted and glued on its surface in a double spiral shape. did. The operation of the boiler main body structure with these configurations will be specifically explained below.
【００２０】 バーナ11からのガスまたはオイルは燃焼室19 で燃焼され高温の燃焼ガスを 発生する。 燃焼ガスは燃焼室19の底部の水冷壁に当たって熱交換して冷却されながら連 絡路15を通って熱交換筒14に入る。このため火炎輻射による整流筒17の過熱は 問題とならない。[0020] Gas or oil from burner 11 is combusted in combustion chamber 19 to produce hot combustion gases. Occur. The combustion gas hits the water-cooled wall at the bottom of the combustion chamber 19, exchanges heat, and continues to be cooled. It passes through the circuit 15 and enters the heat exchange tube 14. Therefore, the overheating of the rectifier cylinder 17 due to flame radiation is Not a problem.
【００２１】 燃焼ガスは熱交換筒14と整流筒17の間を整流筒17の外側に配置した整流板16 にガイドされながら回転して上昇する。この際、燃焼ガスに働く遠心力により 燃焼ガスは外側の熱交換筒14になめるように接触して効率の良い熱交換が行わ れる。このように簡単な構造で従来の単筒式と異なり熱交換率を向上させるこ とができる。整流板16のピッチの間隔は燃焼ガスの冷却による体積の減少に対 応して徐々に小さくしてあるため、燃焼ガスの流速を一定に保って効率の良い 熱交換ができる。[0021] The combustion gas is passed between the heat exchange cylinder 14 and the rectifier cylinder 17 through a rectifier plate 16 arranged outside of the rectifier cylinder 17. It rotates and rises while being guided by. At this time, due to the centrifugal force acting on the combustion gas, The combustion gas comes into contact with the outer heat exchange tube 14 for efficient heat exchange. It will be done. This simple structure improves the heat exchange rate unlike the conventional single cylinder type. I can do that. The pitch of the baffle plate 16 is set to prevent the volume from decreasing due to cooling of the combustion gas. The flow rate of the combustion gas is kept constant and the flow rate of the combustion gas is kept constant, resulting in high efficiency. Capable of heat exchange.
【００２２】 充分に熱交換されて冷却された燃焼ガスは、煙突接続口20を経て排出される 。 一方、熱交換され温度が上昇したボイラ水12は、ボイラ本体上部の出湯口26 から送り出され、水は下部の給水口25から供給される。[0022] The combustion gas that has been sufficiently heat exchanged and cooled is discharged through the chimney connection port 20. . On the other hand, the boiler water 12 whose temperature has increased due to heat exchange is transferred to the outlet 26 at the top of the boiler body. The water is supplied from the water supply port 25 at the bottom.
【００２３】 このようにして本考案実施例のボイラ本体構造は簡単な構造としたため低コス トで製造することができ、メンテナンスも容易に行うことができるとともに、高 い熱交換効率を提供する。[0023] In this way, the boiler main body structure of the embodiment of the present invention has a simple structure, resulting in low cost. It can be manufactured in a single process, easy to maintain, and has a high Provides high heat exchange efficiency.
