持させる加熱装置いわゆるバーナーの改良に関するもの
である。[Detailed description of the invention] This invention relates to an improvement of a heating device, so-called burner, for heating and maintaining a uniform temperature inside an annealing furnace or a heating furnace.
従来の燃焼炉や加熱炉に用いられているバーナーでは、
なるべく炉床面近くに設置したい場合でも、第６図及び
第７図に示す如くバーナーアイル２ａの燃焼ガス出口３
ａの形状が円形に形成されているので取付高さが高くな
るとともに、火焔も大きくなり浮上りの傾向を生じる。In burners used in conventional combustion furnaces and heating furnaces,
Even if you want to install it as close to the hearth surface as possible, the combustion gas outlet 3 of the burner aisle 2a as shown in FIGS.
Since the shape of a is circular, the installation height becomes high and the flame becomes large, causing a tendency for floating.
従って、被熱物用架台の高さをかなり高くしなければな
らず、バーナーの直火を避ける為に被熱物自体もバーナ
ーから遠く離さなければならながった。Therefore, the height of the pedestal for the heated object had to be made considerably high, and the heated object itself had to be placed far away from the burner to avoid direct flame from the burner.
しがして、従来のタイプでは炉内有効寸法は狭められ、
架台が高い為に被熱物の積載作業に難渋するばがっでな
く被熱物の形状によっては安全面における危険性をもは
らんで゛いた。However, in the conventional type, the effective dimension inside the furnace is narrowed,
Not only is it difficult to load objects to be heated due to the height of the pedestal, but it also poses a safety risk depending on the shape of the objects to be heated.
なお、図中１０ａはサイトホールである。Note that 10a in the figure is a sight hole.
本考案は叙上の問題点を克服すべく意図したもので、バ

す如く炉内温度を均一に加熱保持することが出来る。In the above configuration, while the pilot burner 5 is ignited and the combustion mixture gas is sent to the burner tile 2 via the feed pipe 4, the high speed jet nozzle 6...6 is sent via the air pipe 7. When air for stirring the furnace air is ejected so as to converge with the combustion gas flame, an extremely effective combustion state is created in the furnace, and the temperature inside the furnace is maintained uniformly as shown in the measurement results in Figures 3 to 5. You can.

顕著な実効を奏するものである。As mentioned above, the heating device according to the present invention has the combustion gas outlet 3 of the burner tile 2 placed as close as possible to the hearth,
In addition, a plurality of high-speed jet nozzles 6 are arranged in a portion other than the lower part of the combustion gas outlet 3, and the jet direction of the high-speed jet nozzles 6 is inclined downward, so that the effective size inside the furnace is expanded. This has a remarkable effect on the economic efficiency and workability of the furnace.
また、本考案に係る加熱装置は、燃焼ガス出口３を水平
方向に長い横長の長円形に形成して構成されているので

。In addition, since the heating device according to the present invention is configured such that the combustion gas outlet 3 is formed into an oblong shape that is elongated in the horizontal direction, the burner installation height can be lowered and the combustibility is improved. In addition to enlarging the effective dimensions of the furnace, it is possible to heat the furnace uniformly, and since the flame is short and spread flat, temperature compensation between burners is improved.

ことが出来、炉の有効寸法の拡大並びに炉の均一加熱に
一層役立つものである。Furthermore, the heating device according to the present invention tilts the ejection direction of the high-speed ejection nozzle 6 downward, and when viewed from above, the ejection direction of the high-speed ejection nozzle 6 is directed in the direction of extension of the center line passing through the combustion gas outlet 3. Since the head is opened to accommodate the combustion gas, the combustion gas mixes well and is pressed downward, making it possible to make the pedestal for heated objects much lower than before, expanding the effective dimensions of the furnace, and increasing the height of the furnace. This is more useful for uniform heating.
しかも噴出空気を直接空気管から引き出す方式にしたこ
とにより設備費が低減され構造が簡略化される特長を有
するものである。Furthermore, by using a system in which the ejected air is drawn directly from the air pipe, the equipment cost is reduced and the structure is simplified.
なお、本装置はガス燃料のみならずオイル燃料にも適用
できるものである。Note that this device can be applied not only to gas fuel but also to oil fuel.
