Description
【発明の詳細な説明】
液体燃料特に石油系燃料は低温度にて金属面から蒸発せ
しめると、一瞬にして蒸発せず、金属面上において環流
現象を起こし、タール化する。DETAILED DESCRIPTION OF THE INVENTION When liquid fuel, particularly petroleum-based fuel, is evaporated from a metal surface at low temperature, it does not evaporate instantly, but causes a reflux phenomenon on the metal surface, turning into tar.
従って燃料が滴下する金属面あるいはその付近の雰囲気
温度はある程度以上の温度を必要とする。Therefore, the atmospheric temperature on or near the metal surface on which the fuel is dripped needs to be at a certain level or higher.
本発明はこの目的に対応するよう、あらかじめ空気、ま
たは空気と水を加熱させ、加熱水蒸気含有空気とし水蒸
気の持っている高い熱容量を有効に利用し、液体燃料を
この中でスムーズに蒸発させるようにしたものである。In order to meet this objective, the present invention heats air or air and water in advance to create heated water vapor-containing air, effectively utilizing the high heat capacity of the water vapor, and smoothly evaporating liquid fuel in the heated water vapor-containing air. This is what I did.
なお、その際炭化水素のスチームリフオーミング現象も
併せて採り入れ、燃焼に適したガス化燃焼バーナーに関
するものである。The present invention also incorporates the steam re-forming phenomenon of hydrocarbons and relates to a gasification combustion burner suitable for combustion.
その中で本目的の最も重要な点は全一次空気燃焼では燃
焼炎が非常に不安定であるので、反応管内に別の回路を
設は二次空気としてとりだした点にある。Among these, the most important point for this purpose is that since the combustion flame is extremely unstable in all primary air combustion, a separate circuit was set up inside the reaction tube and the secondary air was taken out.
従来の液体燃料の気化バーナーの主流を占めるものはシ
ーズヒーターその他の電気ヒーターを利用しての加熱方
式、あるいは燃焼熱を利用しても、液体燃料のみの気化
、あるいは加熱空気中への気化としての様式で、スチー
ムリフオーミングのようにあまり大量のエネルギーを必
要としていなかった。The mainstream of conventional liquid fuel vaporization burners is a heating method using a sheathed heater or other electric heater, or even if combustion heat is used, it vaporizes only the liquid fuel or vaporizes it into heated air. This method did not require a large amount of energy like steam refrigerating.
またこのような気化方式では温度が高すぎても、あるい
は低すぎてもタール化の原因となり雰囲気を含めた蒸発
環境の潜在熱量も小さいので気化量も不安定に脈動燃焼
の原因ともなっていた。In addition, in such a vaporization method, if the temperature is too high or too low, it will cause tar formation, and since the latent heat capacity of the evaporation environment including the atmosphere is small, the amount of vaporization will be unstable, causing pulsating combustion.
本発明による液体燃料気化バーナのように、燃焼ガスの
温度を効率良く採り入れるようにした様式および液体燃
料気化の前に水蒸気を発生させ、水蒸気混合加熱空気を
用い、さらに反応管を二つに分け、一方に二次空気を流
し、保炎性を良くしたバーナーは例を見ない。The liquid fuel vaporizing burner according to the present invention uses a method that efficiently takes in the temperature of the combustion gas, generates water vapor before vaporizing the liquid fuel, uses water vapor mixed heated air, and further divides the reaction tube into two. , there is no precedent for a burner that allows secondary air to flow on one side to improve flame stability.
また、構成的にみてもバーナ一部と排気系を兼ね備え、
同時に取りはずし可能なバーナーも例が無い。Also, from a structural standpoint, it combines part of the burner and exhaust system,
There is also no example of a burner that can be removed at the same time.
第１図において示したものは本発明の概念図で、送風器
１から送られた燃焼空気は予熱室２内の電気ヒーター３
により加熱され、本発明の特徴である二重管４に入り内
管１と外管８に分れる。What is shown in FIG. 1 is a conceptual diagram of the present invention, in which combustion air sent from a blower 1 is sent to an electric heater 3 in a preheating chamber 2.
The tube is heated by the tube and enters the double tube 4, which is a feature of the present invention, and is divided into an inner tube 1 and an outer tube 8.
二重管４を下がってゆく加熱空気内に液体燃料９及び水
１０を二重管のいずれかに添加する。Liquid fuel 9 and water 10 are added into the heated air flowing down the double pipe 4 into either of the double pipes.
第１図イでは外管に、口では内管に入れた例である。Figure 1A shows an example in which the tube is placed in the outer tube, and in the mouth it is placed in the inner tube.
この二重管を下がってゆく間に管内の触媒および外部か

質された燃料ガスはバーナー噴出口１１より炎となり燃
焼する。While going down this double pipe, steam reforming occurs due to the catalyst inside the pipe and heat received from the outside, and the reformed fuel gas becomes a flame from the burner jet port 11 and burns.
その燃焼をより安定なものに保つため、もう一方の管を
通過してきた二次空気をバーナー噴出口１１の近傍に設
けた二次空気開口部１２を通して流れ出るようにさせで
ある。In order to keep the combustion more stable, the secondary air that has passed through the other tube is made to flow out through a secondary air opening 12 provided near the burner outlet 11.
具体的に本発明を応用した構成例であるボイラーを第２
図に示す。A boiler, which is a specific example of a configuration to which the present invention is applied, is shown in the second example.
As shown in the figure.

。In FIG. 2, a hot water boiler body part 15 consisting of an inner can body 12 having a cylindrical shape, an outer can body 14 which is also cylindrical and having several sockets 13, and a liquid fuel introduced as part of a burner are shown. A boiler is mainly composed of a pipe 16 and a gasification reaction pipe 18 to which a water introduction pipe 17 is connected.
バーナ一部にはあらかじめ送入空気をバーナーに送り込
むための送風ファン１９が缶体上部の燃焼熱を効率良く
吸収する構造を持った空気予熱室２０に接続されている
。In a part of the burner, a blower fan 19 for feeding air into the burner is connected to an air preheating chamber 20 having a structure to efficiently absorb combustion heat from the upper part of the can.
また空気予熱室にはあらかじめ送入空気あるいはガス化
反応管１８を充分加熱するために電気ヒーター２１が設
置され、燃焼初期に通電加熱されるようになっている。Further, an electric heater 21 is installed in the air preheating chamber in order to sufficiently heat the incoming air or the gasification reaction tube 18 in advance, and the electric heater 21 is heated at the initial stage of combustion.
このようにして加熱された空気はガス化反応管１８上部
より入り、その箇所において二重に分かれた反応管の内
管２２と外管２３とに分かれる。The air thus heated enters from the upper part of the gasification reaction tube 18, and is divided into an inner tube 22 and an outer tube 23 of the reaction tube at that point.
内管２２へは内部上部に開けた穴２４より内に導かれ、
そのまま下方に行きバーナー底部の二次空気出口２５で
ボイラー火室内に供給される。The inner tube 22 is guided inward through a hole 24 made in the upper part of the interior.
The air continues to flow downward and is supplied into the boiler fire chamber through the secondary air outlet 25 at the bottom of the burner.
一方、外管２３側に流れた加熱空気は途中で燃料及び水
が導入され、気化部２６においてガス化され、外管外部
より、燃焼熱で加熱されスチームリフオーミングを起こ
しながら下方に下がる。On the other hand, the heated air flowing toward the outer tube 23 side is introduced with fuel and water on the way, is gasified in the vaporization section 26, and is heated by combustion heat from the outside of the outer tube and falls downward while causing steam reforming.
この途中においてこの改質ガス反応を促進させるための
触媒２７が設けられている。A catalyst 27 is provided in the middle of this process to promote this reformed gas reaction.
外管２３下端にはガス化燃料を吹き出すため円筒管に無
数の細穴を開け、燃焼炎をボイラー火室２８に吹き出す
バーナ噴出口２９が接続されている。A burner spout 29 is connected to the lower end of the outer tube 23 to blow out combustion flame into the boiler firebox 28 by making numerous small holes in the cylindrical tube to blow out the gasified fuel.
さらにガス化反応管１８にはバッフルプレート３０が取
り付けられ、燃焼ガスの温度が効率良く反応管に取り込
まれるようになっている。Furthermore, a baffle plate 30 is attached to the gasification reaction tube 18 so that the temperature of the combustion gas is efficiently introduced into the reaction tube.
その他、本バーナには燃焼点火のためのスパーク点火器
３１及び高圧電線トランス３２、また液体燃料導入管１

ポンプ３３．３４が接続されている。In addition, this burner includes a spark igniter 31 for igniting combustion, a high-voltage electric wire transformer 32, and a liquid fuel introduction pipe 1.
Electromagnetic pumps 33 and 34 for feeding the respective liquids are connected to the middle of the water introduction pipe 6 and the water introduction pipe.
またボイラー缶体の底には燃焼熱を遮断するため耐火レ
ンガ３５が底に設けられている。Further, a refractory brick 35 is provided at the bottom of the boiler body to block combustion heat.
第３図はバーナ一部の詳細を示し、内管２２下部の外側

ネジ３７を持った二次空気調整口３８が設けられ、これ
を回転することにより、内管２２と二次空気調整口の間
の間隙３９をコントロールすることができ、二次空気量
の増減が可能となる。FIG. 3 shows details of a part of the burner. The outer side of the lower part of the inner tube 22 has an outer thread 36, and a secondary air adjustment port 38 with an inner thread 37 is provided to be connected to this. By rotating this, the gap 39 between the inner tube 22 and the secondary air adjustment port can be controlled, and the amount of secondary air can be increased or decreased.
上記の例は内管２２を二次空気の通過管として用いた場
合で、この場合には二次空気の増減が容易となる。The above example is a case where the inner tube 22 is used as a passage tube for secondary air, and in this case, it is easy to increase or decrease the amount of secondary air.
また反応管外部より、より熱を供給されやすいことを考
えると内管２２を二次空気の通過管として利用したほう
がより有利であるといえる。Furthermore, considering that heat is more easily supplied from the outside of the reaction tube, it can be said that it is more advantageous to use the inner tube 22 as a passage tube for secondary air.
次に本発明の効果について説明する。Next, the effects of the present invention will be explained.
従来の全一次空気によるガス化燃焼方式は非常に燃焼幅
