ように設定されている。In this embodiment, the burner 1 comprises an inner burner 1A and an outer burner 1B having a double wall structure. In addition, the inner nozzle 11A and the outer nozzle 11B which are circularly double-walled and are coaxially arranged.
The nozzle 11 is made up of: and the nozzle 11 is squeezed toward the tip, and the degree of squeezing is set to decrease toward the tip.

する。The air-fuel mixture supply device 2 distributes air pressure-fed from a blowing unit (not shown) to the air passage 21A for the inner nozzle 11A and the air passage 21B for the outer nozzle 11B, and the air passage 21A.
21B are provided with air amount adjusting valves 22A and 22B for adjusting the air amount, respectively. Further, the fuel gas supplied from the gas pipe is supplied to the gas passage 23A for the inner nozzle 11A.
And gas quantity adjusting valves 24A and 24B for adjusting the gas quantity respectively are installed in the gas paths 23A and 23B. Ventilation path 21A
The gas passage 23A, or the ventilation passage 21B and the gas passage 23B are connected downstream to form the air-fuel mixture supply passages 25A and 25B, which supply the air-fuel mixture to the inner burner 1A and the outer burner 1B, respectively.
バーナ１は、混合気供給装置２で予混合された混合気が
下方から供給され、絞られたノズル１１の円形噴出口１
２に設けられた整流板１３で整流され、該噴出口１２か
ら上方に噴出される。The burner 1 is supplied with the air-fuel mixture premixed by the air-fuel mixture supply device 2 from below, and the circular ejection port 1 of the nozzle 11 is narrowed down.
It is rectified by the rectifying plate 13 provided on the No. 2 and is ejected upward from the ejection port 12.
（作用） 前記噴出口１２から噴出される予混合気は、噴出口１２
において均一の噴出速度Ｖ０の噴流４となっている。(Operation) The premixed gas ejected from the ejection port 12 is
The jet flow 4 has a uniform jet velocity V 0 .
噴流４は、上昇するに従い漸次水平方向に拡散して、流
域の断面積を広げる。それと共に、垂直方向の噴流４の
流速Ｖは、漸減していき、噴流４の中心線と遮蔽面との
交点で噴流４の流速Ｖ＝０の澱点となる。The jet flow 4 gradually diffuses in the horizontal direction as it rises, expanding the cross-sectional area of the basin. Along with that, the flow velocity V of the jet flow 4 in the vertical direction gradually decreases, and becomes a stagnation point of the flow velocity V = 0 of the jet flow 4 at the intersection of the center line of the jet flow 4 and the shielding surface.
噴流４は、遮蔽板３によって偏向され、遮蔽板３に沿っ
て放射状に広がる。噴流４と外気との境界では、粘性に
よるせん断層４３が生じる。The jet 4 is deflected by the shield plate 3 and spreads radially along the shield plate 3. At the boundary between the jet 4 and the outside air, a shear layer 43 due to viscosity is generated.
遮蔽板３に沿っては、柱状突起３Ｃによって境界層が乱
流４４Ｂとなり、噴流４の滞留時間が伸びる。Along the shield plate 3, the boundary layer becomes a turbulent flow 44B due to the columnar projections 3C, and the residence time of the jet flow 4 is extended.
この状態で噴流４に点火すると、予混合気の火炎伝播速
度Ｓと、噴流４の流速Ｖとが釣り合った面において薄膜
の燃焼火炎５が形成される。When the jet flow 4 is ignited in this state, a thin-film combustion flame 5 is formed on the surface where the flame propagation velocity S of the premixed air and the flow velocity V of the jet flow 4 are balanced.
この燃焼火炎５は、噴出速度Ｖ０が大きくなるか、また
は予混合気の空燃比がリーン（燃焼空気の過多）になる
などで火炎伝播速度Ｓが低下すると遮蔽板３側に変位
し、その逆のときは噴出口１２側に変位する。すなわち
噴出速度Ｖ０＞Ｓ（火炎伝播速度）である限り、噴出口
１２と遮蔽面との間には、噴流４の流速Ｖ＝Ｓ（火炎伝
播速度）となる面は必ず存在するので、噴出速度Ｖ０が
増大しても吹消えによる失火は生じ難い。The combustion flame 5 is displaced to the shield plate 3 side when the flame propagation speed S decreases due to a high ejection speed V 0 or a lean air-fuel ratio of the premixed air (excessive combustion air). In the opposite case, it is displaced toward the ejection port 12 side. That is, as long as the jet velocity V 0 > S (flame propagation velocity), there is always a surface where the flow velocity V = S (flame propagation velocity) of the jet flow 4 exists between the jet outlet 12 and the shielding surface. Even if the speed V 0 increases, a misfire due to blowout is unlikely to occur.
このように、この燃焼機器Ｂでは、燃焼量の変化や、空
気過剰率の変動、あるいは空気中の酸素濃度の変化に対
し、薄膜状の燃焼火炎５の形成位置が幾分変化するだけ
で、燃焼自体は極めて安定している。As described above, in the combustion device B, the formation position of the thin film combustion flame 5 is slightly changed with respect to the change of the combustion amount, the change of the excess air ratio, or the change of the oxygen concentration in the air. The combustion itself is extremely stable.
しかし、薄膜状の燃焼火炎５は、熱が多量に散逸し、燃
焼温度が低くなることにより、燃焼性あるいは熱効率の
低下を誘起する。However, the thin film combustion flame 5 dissipates a large amount of heat and lowers the combustion temperature, thereby inducing a decrease in combustibility or thermal efficiency.
この欠点に対応し、下側面に柱状突起３Ｃを円形状に密
集して設けた遮蔽板３により、境界層が乱流４４Ｂとな
り、柱状突起３Ｃの間で燃焼ガスの分子運動が増大し、
乱流４４Ｂにより熱伝達性が向上し、又、触媒３Ｄの作
用により、噴流４中の未燃分が完全燃焼する。In response to this drawback, the boundary plate becomes a turbulent flow 44B due to the shielding plate 3 in which the columnar protrusions 3C are densely arranged in a circular shape on the lower surface, and the molecular motion of the combustion gas increases between the columnar protrusions 3C.
The heat transfer property is improved by the turbulent flow 44B, and the unburned components in the jet flow 4 are completely burned by the action of the catalyst 3D.
（効果） 薄膜状火炎のガス燃焼機器Ｂは、乱流による分子運動の
増大により燃焼性が向上し、ＣＯおよびＨＣの発生が抑
えられ、熱効率が良くなる。(Effect) In the gas combustion device B of thin film flame, combustibility is improved due to an increase in molecular motion due to turbulent flow, generation of CO and HC is suppressed, and thermal efficiency is improved.
本発明は、上記実施例以外に、つぎの変形例を含む。The present invention includes the following modified examples in addition to the above-described embodiments.
ａ．遮蔽板は噴流の軸心に対し幾分傾斜して配置されて
も良く、また曲率半径の大きな曲面もしくは鈍角円錐面
であっても良い。a. The shield plate may be arranged at a slight inclination with respect to the axis of the jet flow, or may be a curved surface with a large radius of curvature or an obtuse conical surface.
ｂ．噴出口は円形の他、正方形などの正多角形であって
も良い。b. The ejection port may have a regular polygonal shape such as a square, as well as a circular shape.
ｃ．噴出口から噴出する混合気は、空気過剰率が１以上
