式バーナに関する。[Detailed description of the invention] The present invention has a gas permeable catalyst layer inside the burner body facing the rectangular opening, and a gas permeable catalyst layer located inside the catalyst layer. The present invention relates to a catalytic layer combustion type burner that is provided with a heat insulating material layer and configured to burn fuel gas that has passed through the heat insulating material layer and the catalyst layer by the action of the catalyst layer and by external air.

下向きにすると、燃焼部Aの中央部分での燃焼性
が悪化する欠点があつた。 To configure the above burner, conventionally, as shown in FIG. It was designed to burn by natural mixing with air in the atmosphere. However, when a low oxygen concentration atmosphere is created due to long-term combustion, such as in a naturally ventilated drying room, combustibility deteriorates and sometimes incomplete combustion occurs. In this case, there was a drawback that the combustibility in the central part of the combustion section A deteriorated, especially when the combustion direction A was directed downward.
本考案の目的は、バーナの設置環境や燃焼部の
大きさ及び向きいかんにかかわらず、燃焼部全体
の良好な燃焼を確実に行えるようにすると共に、
そのための構成を製作簡単なものにすることにあ
る。 The purpose of this invention is to ensure good combustion in the entire combustion section, regardless of the installation environment of the burner, the size of the combustion section, and the direction of the combustion section.
The purpose is to make the configuration for this purpose easy to manufacture.
本考案の特徴構成は、燃焼部となるバーナ本体

つて沿う状態で空気圧送用パイプを設け、前記パ
イプにそのほぼ全長にわたつて、燃焼反応を生じ
させる触媒層の表面に沿う方向に燃焼用空気を噴
出するスリツトを設けたことにある。 The characteristic configuration of the present invention is that an air pressure feeding pipe is provided along almost the entire length of the long side of the rectangular opening of the burner main body, which is the combustion section, This is because a slit is provided to blow out combustion air in a direction along the surface of the catalyst layer where the reaction occurs.
本考案特徴構成による効果は次の通りである。 The effects of the feature structure of the present invention are as follows.
(1) スリツトから触媒層表面近くの燃焼部に燃焼
用空気を強制的に供給すると共に、スリツトを
そこから噴出された空気が燃焼部全体に均一供
給しやすいように長方形状開口部の長辺に沿わ

つて、たとえ低濃度酸素雰囲気下でも、あるい
は、燃焼部を大きくしたり下向きにしても、燃
焼部全体に対する十分量の燃焼用空気供給を確
実に行つて、良好な燃焼を行わせられるように
なつた。(1) In addition to forcibly supplying combustion air from the slits to the combustion section near the surface of the catalyst layer, the long sides of the rectangular openings are designed to make it easier to uniformly supply the air ejected from the slits to the entire combustion section. By arranging it along almost the entire length of the combustion chamber, a sufficient amount of combustion air can be supplied to the entire combustion section even under a low concentration oxygen atmosphere or even if the combustion section is enlarged or facing downward. Now I can do it reliably and get good combustion.
(2) 上記効果(1)を得るに、例えば多数のノズルを
開口部の辺に沿つて並設する等の場合、組付け
作業工数が多くなつたり、あるいは、均一な燃
焼用空気供給が行えるように配置するに手間を
要したりする等の欠点を伴うが、スリツト付の
パイプを利用すると、製作が簡単で均一供給が
できるようになり、実用化に適したものにでき
る。(2) In order to obtain the above effect (1), for example, if a large number of nozzles are installed in parallel along the sides of the opening, the number of assembly steps will increase, or a uniform combustion air supply will not be possible. Although there are drawbacks such as the need for time and effort to arrange the pipe, if a pipe with slits is used, manufacturing is easy and uniform supply can be achieved, making it suitable for practical use.
