【発明の詳細な説明】
本発明は炉内温度1400℃〜1900℃の高温炉に使
用されるバーナ機構の改良に関するものであり、
バーナ部からの熱損失を減少させる省エネルギー
型ガスバーナを提供することを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a burner mechanism used in a high-temperature furnace with an internal temperature of 1400°C to 1900°C.
An object of the present invention is to provide an energy-saving gas burner that reduces heat loss from a burner section.
1400℃〜1900℃の高温炉、特にトンネルキルン
に使用されている従来のバーナは、1400℃〜1900
℃という炉内からの高温雰囲気及び温度550℃〜
1200℃の高温二次空気からバーナ先端部を保護す
るため水冷管を併用している。 Conventional burners used in high-temperature furnaces, especially tunnel kilns,
℃ high temperature atmosphere from inside the furnace and temperature 550℃~
A water-cooled pipe is also used to protect the burner tip from high-temperature secondary air of 1200℃.
さらに最近は、省エネルギーの一環として、廃

るバーナでは、高温酸化等の短命化の方向をたど
つている。この高温化からバーナの先端を保護す
るためこの種の多くのバーナは水冷方式を採用し
ている。 Furthermore, recently, as part of energy conservation, it has become increasingly common to recover and use waste gas sensible heat as secondary air for combustion, and as the temperature of secondary air for combustion increases, conventional metal nozzles Burners are moving toward shorter lifespans such as high-temperature oxidation. In order to protect the tip of the burner from this high temperature, many burners of this type use a water cooling system.
しかしこのような水冷式バーナは下記のごとき
欠点を有している。すなわち水冷による熱損失が
バーナ１本当り8000〜12000KCal／hrと多く、か
つ水冷管の漏水トラブル及び先端部へのカーボン
付着等の問題もありバーナの保守管理に多くの労
力を必要とする。例えばバーナ本数が16本のトン
ネルキルンの場合の全水冷熱損失は128000〜
192000KCal／hrとなる。そしてたとえ水冷方式
を採用しても、高温炉に使用する場合はその寿命
が短く、長期使用には不向きであるという欠点が
あつた。 However, such water-cooled burners have the following drawbacks. That is, the heat loss due to water cooling is as high as 8,000 to 12,000 KCal/hr per burner, and there are also problems such as leakage of water cooling pipes and carbon adhesion to the tips, which requires a lot of effort to maintain and manage the burners. For example, in the case of a tunnel kiln with 16 burners, the total water cooling heat loss is 128,000 ~
192000KCal/hr. Even if a water-cooled system were adopted, the service life would be short when used in a high-temperature furnace, making it unsuitable for long-term use.
本発明は前記の水冷式バーナの諸問題を解決す
べくなされたものである。 The present invention has been made to solve the problems of the water-cooled burner described above.

するバーナである。 If high-temperature burners are not water-cooled, a high-temperature refractory material is required in place of metal. Ceramic materials are generally considered for this, but ceramic materials have (1) poor resistance to thermal shock, and (2) metal There are problems such as damage due to the difference in expansion between the ceramic material and the ceramic material. For this reason, among the members that make up the burner, we first considered using ceramic for the tip and the outer peripheral protection tube to suppress the effects of radiant heat received by the tip and cross-flow heat from high-temperature secondary air. In particular, the ceramic material used in the present invention is selected to be of a material that can sufficiently withstand thermal shock, and the joint with the metal has a structure in which the difference in expansion does not have a relatively negative effect.
Furthermore, this burner is characterized by a structure that has a sufficient air cooling effect by using a small amount of cooling air to reduce heat accumulation in the inner metal part and prevent overheating.

ナ。1. In the center of the burner, at its tip, an insert member having a central nozzle hole formed therein is communicated with the primary air vent via a fuel gas nozzle mounting member having a primary air vent groove formed in a part of the outer periphery, and A fuel gas pipe is provided with a fuel gas nozzle having a primary air groove formed in a part of the built-in outer circumference separated by a fuel gas passage groove, and an appropriate interval is provided between the fuel gas pipe and the outside of the fuel gas pipe. An air pipe is arranged in which a ceramic air nozzle is attached via an air nozzle mounting member having a cooling air ventilation groove, and a centering member with a cooling air ventilation groove is provided inside the connection member between the air cooling pipe and the protection tube. A ceramic protection tube is attached to the outside of the air pipe and inside the furnace via a connecting member.
An air-cooled pipe with cooling air branch holes is provided, and the base ends of the fuel gas pipe, air pipe, and air-cooled pipe are configured to be connectable to the fuel gas pipe, primary air pipe, and air-cooled pipe, respectively. and the space around the air pipe, air nozzle mounting member, and air nozzle, the main cooling air flow path consisting of the cooling air ventilation groove that communicates these spaces, the space around the air cooling pipe and the protective cylinder, and these spaces. A side-combustion type high-temperature ceramic burner having a cooling air flow path consisting of a connecting member ventilation groove and a branch cooling air flow path consisting of cooling air branch holes.
