Description of the invention: / Technical field to which the invention pertains. The present invention relates to a heating device for heating a heated fluid. This case is based on the priority of 2008-053901, which was filed on March 4, 2008 in Japan, and the priority of 2008-053903, which was filed on March 4, 2008 in Japan. [Prior Art] In a restaurant or accommodation facility, there is a case where a small heating device for conditioning water or steam for use in a bathroom is provided. For example, a heating device is disclosed in which a fuel is heated together with combustion air, and the water flowing in the pipe is heated by the generated combustion gas at a south temperature, and the water is obtained by the water. Further, the heating device is used in addition to the generation of steam or water, and is also used for heating various fluids (heated fluid) (see Patent Document 1). (Patent Document) Japanese Laid-Open Patent Publication No. 2007-139358 (Summary of the Invention) However, in the conventional heating device, in order to read the time of complete combustion in the combustion chamber, it is necessary to have a flaw. The combustion chamber. Therefore, the heating device cannot be sufficiently miniaturized. Therefore, by preheating the unburned gas with the combustion gas and then burning it, the flame can be stably maintained even in a small combustion chamber. However, since the combustion gas is extremely high in temperature, it is possible to excessively be heated before the unburned gas is supplied to the combustion chamber to cause the unburned gas itself to ignite or to generate a burn, and to burn outside the combustion chamber. Moreover, from the large combustion 321077 3 200946838 room heat dissipation to the surrounding heat will be paralyzed, resulting in reduced energy efficiency. The present invention has been developed in view of the foregoing problems, and the purpose of the invention is to add a towel to the heated fluid to make the _ money small, and the flame is stabilized to improve energy efficiency. (Means for Solving the Problem) In order to achieve the purpose of the present invention, the present invention provides a heating device for heating a heated fluid, which has a flow path of 帛i, which causes a quenching distance to pass through the enthalpy (the flame approaches the solid wall to a certain distance

Since the second flow path is formed around the second flow path, it does not come into contact with the first flow path. Therefore, the heat transferred from the combustion gas = part of the heat will be dissipated from the unburned gas. Further, in the present invention, it is also possible to have a configuration in which the third flow path through which the heated fluid flows and which flows. In addition, according to the heating device, the internal space of the third flow path system is configured, and the flow path is sandwiched between the first g-distribution 321077 4 200946838 tube and the third pipe concentrically surrounding the third pipe. The space of the pipe is configured such that the second flow path is constituted by a space sandwiched between the first pipe and the second pipe concentrically surrounding the first pipe. In the above configuration, a plurality of fins protruding from the outer peripheral surface of the third pipe toward the first flow path may be provided. Furthermore, in the above configuration, the third pipe is bent on the first flow path side and the second flow path side at every predetermined interval. Further, the configuration may include a configuration in which the first flow path formed around the second flow path and the third flow path formed in the first flow path are provided. According to the heating device, the first flow path is formed around the second flow path through which the unburned gas flows, and the combustion gas flows through the second flow path. Therefore, the unburned gas system flowing through the second flow path is heated by the combustion gas flowing at a high temperature in the first flow path. The unburned gas is ejected from the second flow path through a nozzle hole which is set to have a smaller escape distance than the flame at a flow rate at which the flame can be maintained, thereby forming a stable flame. Further, the unburned gas is burned by the stable flame, and the third flow path is formed around the i-th flow path through which the combustion gas flows. The heated fluid flows through the third flow path. Further, in the above configuration, the introduction portion of the combustion gas may be introduced from the second flow path in a region on the side opposite to the first flow path in the outer region of the third flow path. Further, in the above configuration, the second flow path is constituted by an internal space of the second pipe, and the first flow path is sandwiched between the second pipe and the second pipe that surrounds the second pipe concentrically! The space of the pipe is constituted by a space sandwiched between the second pipe and the third pipe which is concentrically surrounded by the first pipe of the first pipe 321077 5 200946838. In the above configuration, the second flow path is formed by a second pipe, and the third flow path is formed by separating the plurality of (four) four pipes from the second pipe around the second pipe. The one flow path may be constituted by a space surrounded by the second pipe, the above-mentioned pipe, and the partition wall of the fourth pipe. (Effect of the invention)
依據本發明之加熱裝置，可發揮以下之優異效果。 ⑴由於流财未燃氣體之第2流路係形成在流通有 燃燒氣體之第1流路的周圍，因此第2流路之全周不會與 第1流路賴’而從燃燒氣體傳熱之熱量的—部分會從^ 燃氣體散熱。因此，藉由加熱未燃氣體而可使燃燒室θ變小， 並且抑制未燃氣體之過度加熱，而可在燃燒室形成穩定之 火焰。因此，可使加熱被加熱流體之加熱裝置的燃燒室變 小，而可使燃燒室之火焰穩定。 ’'According to the heating device of the present invention, the following excellent effects can be exhibited. (1) Since the second flow path of the unburned gas is formed around the first flow path through which the combustion gas flows, the entire circumference of the second flow path does not transfer heat from the combustion gas to the first flow path. The heat - part of the heat will be dissipated from the gas. Therefore, the combustion chamber θ can be made small by heating the unburned gas, and excessive heating of the unburned gas can be suppressed, and a stable flame can be formed in the combustion chamber. Therefore, the combustion chamber of the heating means for heating the heated fluid can be made small, and the flame of the combustion chamber can be stabilized. ’
⑵由於在麵有未燃氣體之第2祕周_成有第! 流路，在前述第i流路流通有燃燒氣體，因此，流通於第 2流路之未減體係藉由流通於第丨流路之高溫之燃燒氣 體所加熱。再者’藉由以可維持火焰之流速將未燃氣體從 前述第2流路經由設定成比火焰消失距離小之喷嘴孔喷 出，而形成穩定之火焰。如此，穩定之火焰係即使直接接 觸與冷的被加熱流體相接之壁面接觸，亦可穩定地燃燒， 並且可有效率地將熱傳達至前述壁面。此外，藉由穩定之 321077 200946838 火焰燃燒未燃氣體，並且在流通有燃燒氣體之第i流路的 -1圍形成有第3流路，在前述第3流路流通有被加熱流體。 • 結果’流通於第3流路之被加熱流體係藉由以穩定之火焰 直接加熱第3流路而被加熱。因此，與僅藉由燃燒氣體加 熱被加熱流體之流路的情形相比較，由於可有效率地將熱 量傳熱至被加熱流體，因此可使加熱被加熱流體之加埶梦、 置中的能量效率提升。 〇 (3)流通於第2流路之未燃氣體係藉由流通於第i流路 之高溫之燃燒氣體所加熱，該加熱過之未燃氣體係藉:以 可維持火焰之流速且經由設定成比火焰消失距離小之噴 孔從前述第2流路喷出而燃燒。前述構成係藉由高溫之燃 燒氣體對未燃氣體充分地進行加熱，因此不需要穩定燃燒 用之大的燃燒室，而可在微通道之燃燒室繼續進行燃燒。 因此，可使燃燒室變小，而可使加熱裝置小型化。 【實施方式】 ❹ 以下，參照圖式，以小型鍋爐為例說明本發明之加熱 裝置之一實施形態。再者，在以下之圖式中，為了使各構 件成為可辨視之大小，而適當地變更各構件之縮小比例尺。 (第1實施形態） ° 第1圖至第3圖係示意性顯示本實施形態之小型鍋爐 B1之概略構成圖。第1圖為斜視圖，第2圖為水平剖面圖， 第3圖為垂直剖面圖。如該等圖所示，以俯視觀之，本實 施形態之小型鍋爐B1係具有以同心配置有第丨配管第% 配管）、第2配管2(第2配管）、及第3配管3(第3配管） 321077 7 200946838 之三重管構造。 第1配官1係朝垂直方向延伸，並且將下端11構成為 閉塞端之配管，在下端11附近之側壁部，形成有複數個= 徑設為比未燃氣體之火焰消失距離小之喷嘴孔。再者 第1配管1係由傳熱性高之材料（例如黃銅等）所形成。 第2配管2係朝垂直方向延伸’並且將第j配管上圍 繞成同心圓狀之配管，將下端21構成為閉塞端，與^ ^配 管1同樣地，由傳熱性高之材料所形成。 _(2) Since the second secret phase of the unburned gas is formed on the surface, the first flow path is formed, and the combustion gas flows through the i-th flow path. Therefore, the unreduced system flowing through the second flow path flows through the third stage. The high temperature combustion gas of the flow path is heated. Further, a stable flame is formed by ejecting the unburned gas from the second flow path through a nozzle hole which is set to have a smaller escape distance than the flame at a flow rate at which the flame can be maintained. Thus, the stable flame can be stably burned even if it is in direct contact with the wall surface in contact with the cold heated fluid, and heat can be efficiently transmitted to the aforementioned wall surface. Further, the unburned gas is burned by the flame of 321077 200946838, and the third flow path is formed around -1 of the i-th flow path through which the combustion gas flows, and the heated fluid flows through the third flow path. • As a result, the heated flow system flowing through the third flow path is heated by directly heating the third flow path with a stable flame. Therefore, compared with the case where the flow path of the heated fluid is heated only by the combustion gas, since the heat can be efficiently transferred to the heated fluid, the heating of the heated fluid can be added to the nightmare, the energy of the centering Increased efficiency. 〇(3) The unburned gas system flowing through the second flow path is heated by the high-temperature combustion gas flowing through the i-th flow path, and the heated unfired gas system is used to maintain the flow rate of the flame and set The injection hole having a smaller escape distance than the flame is ejected from the second flow path and burned. In the above configuration, the unburned gas is sufficiently heated by the high-temperature combustion gas, so that a large combustion chamber for stable combustion is not required, and combustion can be continued in the combustion chamber of the microchannel. Therefore, the combustion chamber can be made smaller, and the heating device can be miniaturized. [Embodiment] Hereinafter, an embodiment of a heating apparatus according to the present invention will be described by taking a small boiler as an example with reference to the drawings.

Further, the water flow path R is connected to evaporate the water w of the water stream (4) to generate a near portion (not shown), and the discharge portion discharges the passage R3 to the outside. The steam is full from the water; in addition, it is lost in the third pipe gas G1, and is distributed, and the combustion is generated by the combustion of the unburned gas (10) in the day 1 of the company 1 (the first flow path) ). In other words, in the small boiler B1 of the embodiment of the present invention, the combustion gas flow path R1 is constituted by a space sandwiched between the third distribution pipe 3 and the first pipe 1 that surrounds the third pipe concentrically. . Further, the water flow path R3 is surrounded by the combustion gas flow path R1. Further, the vicinity of the lower end of the combustion gas flow path R1 (near the nozzle hole 12) constitutes a combustion chamber K in which the unburned gas G1 discharged from the nozzle hole 12 is burned. Further, a fire device (not shown) is provided in the combustion chamber K. In the space between the first pipe 1 and the second pipe 2, the unburned gas flow path R2 (second flow ® path) including the unburned gas G1 of the combustible fuel flows. In other words, the unburned gas flow path R2 is constituted by a space sandwiched between the first pipe 1 and the second pipe 2 that surrounds the first pipe concentrically. Further, the upper end portion of the second pipe 2 is connected to an unburned gas supply device (not shown) for supplying the uncombusted gas G1 to the unburned gas flow path R2. Further, as the unburned gas G1, a mixed gas of a fuel and an oxidant can be used, and as the fuel, a petroleum fuel or a natural gas can be used. In the small-sized boiler B1 of the above-described embodiment, first, the unburned gas body q G1 is supplied from the uncombusted gas supply device connected to the second pipe 2 to the uncombusted gas flow path R2, and the pair is formed in the first pipe 1 The unburned gas G1 ejected from the nozzle holes 12 is ignited and burned, thereby forming a flame in the combustion chamber K. Then, the combustion gas G2 generated by burning the unburned gas G1 can be discharged through the combustion gas flow path R1. When the flame is formed in the combustion chamber K as described above, since the combustion gas G2 having a high temperature flows through the combustion gas flow path R1, the unburned gas G1 flowing through the uncombusted gas flow path R2 is heated. In other words, the heat of the combustion gas G2 is transferred to the unburned gas 9 321 077 200946838 body G1 via the first pipe 1 functioning as a heat exchange wall, and the unburned gas G1 is heated. The unburned gas G1 heated by heat exchange with the combustion gas G2 is discharged to the inside of the first pipe 1 through the nozzle hole 12 while being heated. Further, the unburned gas G1 discharged from the nozzle hole 12 is burned in the combustion chamber K. Further, the nozzle hole 12 formed in the first pipe 1 is set to be smaller than the flame disappearing distance of the combustion environment in the combustion chamber K of the unburned gas G1, so that the flame extension to the unburned gas flow path R2 is suppressed. Further, since the unburned gas flow path R2 is formed around the combustion gas flow path R1, the entire circumference of the unburned gas flow path R2 does not come into contact with the combustion gas flow path R1, but heat is transferred from the combustion gas G2. A portion of the heat will dissipate heat from the gas G1. Therefore, excessive heating of the unburned gas G1 can be suppressed, and the flame is prevented from being burned to the uncombusted gas flow path R2, and the unburned gas G1 is self-ignited. As a result, the flame is stabilized in the combustion chamber K, and combustion is continued. Further, as described above, in the state where the combustion in the combustion chamber K is continued, the unburned gas G G1 supplied to the combustion chamber K via the unburned gas flow path R2 flows through the combustion gas flow path R1. The gas G2 is burned and heated. Therefore, even if the combustion chamber K is made smaller than the combustion chamber of the conventional heating device, a stable flame can be formed. When the flame is stably formed in the combustion chamber K and the combustion is continued, the water W of the water flow path R3 is heated and evaporated by the flame of the combustion chamber K and the combustion gas G2 of the combustion gas flow path R1. In other words, the heat generated by the combustion is transferred to the water W through the second pipe 2 functioning as the heat exchange wall, so that the water W is heated and evaporated. Further, the vapor generated by the evaporation of the water W 10 321077 200946838 is discharged to the outside of the small boiler B1 - via a discharge portion (not shown). Here, the water flow path R3 is surrounded by the combustion gas flow path R1. Therefore, heat can be transferred from the entire circumference of the water flow path R3 to the water W, and the water W can be efficiently heated. According to the small boiler B1 of the present embodiment, the unburned gas flow path R2 through which the uncombusted gas G1 flows is formed around the combustion gas flow path R1 through which the combustion gas G2 flows, so that the unburned gas flow path R2 is completely The week does not come into contact with the combustion gas flow path R1, and a part of the heat transferred from the combustion gas G2 is dissipated from the unburned gas G1. Therefore, the combustion chamber K can be made small by heating the uncombusted gas G1, and excessive heating of the uncombusted gas G1 can be suppressed, and a stable flame can be formed in the combustion chamber K. Therefore, the combustion chamber K can be made smaller, and the flame in the combustion chamber K can be stabilized.

Therefore, the flow is in the unburned gas flow path. R2 is not = the milk G1 is heated by the combustion gas flowing at a high temperature in the combustion gas flow path. Further, the unburned gas G1 is never flowed through the flow path R2 by maintaining the flow rate of the flame. The flame is ejected through the nozzle hole 112 which is set to be smaller than the vanishing distance of the flame to form a stable flame. Thus, the stable flame can directly contact the wall surface (the second pipe 1〇1) which is in contact with the cold water W. A water flow path R3 is formed around the combustion gas flow path R1 where the stable flame is formed, and water w flows through the water flow path R3. As a result, the water W flowing through the water flow path R3 directly heats the water flow path by a stable flame. When heated, therefore, heat can be efficiently transferred to the water W as compared with the case where the water flow path R3 is heated only by the combustion gas G2. Therefore, according to the small boiler B101 of the present embodiment, the energy efficiency can be improved. Again, according to this In the small boiler B1〇1 of the embodiment, the unburned gas G1 flowing through the unburned gas flow path R2 is heated by the still-burning combustion gas G2 flowing through the combustion gas flow path R1, and the heated unburned gas G1 is heated. 321077 .16 200946838 is burned by the nozzle hole 112 that can maintain the flow rate of the flame and is set to be smaller than the flame disappearing distance - and is burned from the non-combustible gas flow path R2. The above-mentioned structure is formed by the high temperature. Since the combustion gas G2 sufficiently heats the unburned gas G1, stable combustion can be continued in the small combustion chamber K. Therefore, the combustion chamber can be made smaller, and the heating device can be miniaturized. Thus, according to the present embodiment The small boiler B101' can further reduce the size of the device while improving energy efficiency. (Sixth embodiment) ® Next, another sixth embodiment of the present invention will be described. Further, in the sixth embodiment, In the description, the same portions as those of the fifth embodiment are omitted or simplified. Fig. 10 and Fig. 11 are schematic diagrams showing the schematic configuration of the small boiler B102 of the present embodiment, and the tenth The figure is a horizontal cross-sectional view, and the πth view is an oblique view. As shown in the figures, the unburned gas flow path R2 of the small boiler B102 of the present embodiment is the small boiler B1 〇1 of the fifth embodiment. Similarly, the internal space of the second pipe 102 is configured, and the water flow path R3 is composed of an internal space of a plurality of fourth pipes 104 that are separated from the second pipe 1〇2 around the second pipe 102, and burns. The gas flow path R1 is constituted by a space surrounded by the second pipe 102, the fourth pipe 1〇4, and the partition wall 105 that seals the fourth pipe 104. Further, as shown in Fig. 11, The height of the partition 105 is set to be lower than the height of the second pipe 1〇2 and the fourth pipe 1〇4. As a result, in the upper portion of the small boiler B102, a gap can be generated between the fourth pipes 104. In addition, the gap is a function of introducing the combustion gas G2 into the introduction portion 106 of the region on the side opposite to the combustion gas flow path R1 in the outer region of the water flow path R3 17 321077 200946838. In the small-sized boiler b102 of the present embodiment configured as described above, the unburned gas G1 heated by heat exchange with the combustion gas G2 is discharged to the combustion gas flow path and burned in the same manner as in the fifth embodiment. When a new combustion gas G2 is generated, a part of the combustion gas G2 is wound around the back side of the fourth pipe ι4 via the introduction portion 106 (opposite to the combustion gas flow path R1). Therefore, the entire circumference of the fourth pipe 1〇4 is heated by the combustion gas G2, and the water w can be heated more efficiently. Therefore, energy efficiency can be improved. (Seventh embodiment) Next, another seventh embodiment of the present invention will be described. In the description of the seventh embodiment, the description of the same portions as those of the fifth embodiment will be omitted or simplified. Fig. 12 is a schematic plan view showing a small steel furnace μ〇3 according to a seventh embodiment of the present invention, and is a horizontal sectional view. As shown in Fig. 12, the small-sized boiler crucible 103 of the present embodiment includes a plurality of fins ho protruding from the outer peripheral surface of the first pipe 1〇1 toward the water flow path R3 side. The heat sink is formed integrally with the first pipe 101, and is formed of a material having high heat transfer property similarly to the first pipe 1〇1. According to the small-sized boiler crucible 103 of the present embodiment having the above-described configuration, the heat exchange area of the combustion gas G2 flowing through the combustion gas flow path R1 and the water W flowing through the water flow path R3 is increased by the fins 110, and the heat exchange area can be increased. The water W is heated efficiently. Therefore, the energy efficiency can be further improved. 18 321077 200946838 (Eighth Embodiment) Next, another eighth embodiment of the present invention will be described. Further, in the description of the eighth embodiment, the description of the same portions as the fifth embodiment will be omitted or simplified. Fig. 13 is a schematic sectional view showing a schematic configuration of a small boiler B104 of the present embodiment and is a horizontal sectional view. As shown in Fig. 13, in the small boiler B104 of the present embodiment, the first pipe 1 is bent at a predetermined interval on the side of the combustion gas flow path R1 and the side of the water flow path R3 to form a star shape. In the small boiler B104 of the present embodiment having the above-described configuration, since the first pipe 101 is bent at a predetermined interval to form a star shape, the combustion gas G2 flowing through the combustion gas flow path R1 flows through the water flow path R3. The heat exchange area of the water W is increased, and the water w can be heated more efficiently. Therefore, the energy efficiency can be further improved.
