本発明は、着火スイッチに連動して着火時のみ着火ヒー
タ部に集中的に燃料ガスと空気との混合ガスを供給する
ことにより、着火を確実にするようにした触媒燃焼装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a catalyst that ensures ignition by intensively supplying a mixed gas of fuel gas and air to an ignition heater section only at the time of ignition in conjunction with an ignition switch. This relates to combustion equipment.
メタン、エタン、プロパン、ブタン等の常温で気体であ
るガス燃料、また、ナフサ、ベンジン、アルコール等の
常温で液体である燃料を気化させて触媒の表面で燃焼さ
せ、熱源とする事は従来から知られている。Gas fuels that are gaseous at room temperature, such as methane, ethane, propane, and butane, and fuels that are liquid at room temperature, such as naphtha, benzine, and alcohol, have been vaporized and burned on the surface of a catalyst to be used as a heat source. Are known.
この触媒燃焼では、触媒の温度が一定温度以上に上昇し
ている事が必要であり、着火方法として次のもの−か従
来より用いられていた。In this catalytic combustion, it is necessary that the temperature of the catalyst rises above a certain temperature, and the following ignition methods have been conventionally used.
■、加熱ヒータにより触媒の一部もしくは全部を加熱す
る。(2) Heating part or all of the catalyst with a heater.
■、燃料ガスを予熱して触媒に供給する。(2) Preheat the fuel gas and supply it to the catalyst.
■、燃料ガスに着火し、炎燃焼を行なわせ、その熱で触
媒を加熱し、その後、触媒燃焼に移行させる。(2) The fuel gas is ignited to cause flame combustion, the heat of which heats the catalyst, and then the process shifts to catalytic combustion.
本発明は上記の着火方式のうち、■の方法の改良に関す

従来この方法は、通常の触媒燃焼装置では燃料ガスと空
気の混合ガスを拡散板等を用いて触媒全体に均一に供給
するようにしているため、着火用加熱ヒータと接触した
触媒部への燃料供給が少なく、従って、発熱量も小さい
ところから着火がしにくいという欠点を有していた。Conventionally, with this method, in normal catalytic combustion devices, a mixed gas of fuel gas and air is uniformly supplied to the entire catalyst using a diffuser plate, etc. It had the disadvantage that it was difficult to ignite since the supply was small and the calorific value was also small.
コードレス触媒燃焼機器を目的としたものでは、着火用
加熱ヒータの電源に電池を用いる事が多いため、加熱が
不充分であり、着火はさらにしにくくなる。In cordless catalytic combustion equipment, batteries are often used as the power source for the ignition heater, which results in insufficient heating and makes ignition even more difficult.
本発明は上記従来の欠点を解消したものである。The present invention eliminates the above-mentioned conventional drawbacks.
すなわち、本発明は燃料ガスと空気の混合ガスを着火時
のみ着火スイッチの操作に連動して着火用加熱ヒータに
接した触媒部に集中して供給するようにしたものである
。That is, in the present invention, a mixed gas of fuel gas and air is supplied in a concentrated manner to the catalyst portion in contact with the ignition heater in conjunction with the operation of the ignition switch only at the time of ignition.
以下その実施例を添附図面とともに説明する。Examples thereof will be described below with reference to the accompanying drawings.

＋）端子板８と接続される。The ignition heater 3 is installed in close contact with the catalyst layer 2, and the terminal 4 of the ignition heater 3 is connected to the terminal plate 6 of the ignition switch 5. By operating the ignition switch 5, the battery 7 (
+) Connected to terminal board 8.
また着火ヒータ３の片方の端子９は電池γの（−）端子
板１０に直続されている。Further, one terminal 9 of the ignition heater 3 is directly connected to the (-) terminal plate 10 of the battery γ.
このようにして、着火ヒータ３に電流が流れ加熱される
ように接続されている。In this way, the ignition heater 3 is connected so that current flows therethrough and heats it.
燃料ガスと空気の混合ガスは導管１１を経てノズル１２
より噴射される。The mixed gas of fuel gas and air passes through a conduit 11 to a nozzle 12.
More sprayed.
ノズル１２は着火スイッチ５の操作と連動して動くよう

バネである。13 is a connecting rod that transmits the movement of the ignition switch 5 to the nozzle 12, and 14 is a spring that keeps the nozzle 12 away at all times.
また１５は燃焼筒１の温度上昇を色で知らせしめるため
の示温材であり、１６は操作部のケースである。Further, 15 is a temperature indicator for indicating the temperature rise of the combustion tube 1 by color, and 16 is a case of the operating section.
上記の構成において、着火スイッチ５を着火位置まで操
作すると（第１図の状態）、着火ヒータ３に電流が流れ
、着火ヒータ３と密着している触媒部が加熱される。In the above configuration, when the ignition switch 5 is operated to the ignition position (the state shown in FIG. 1), a current flows through the ignition heater 3 and the catalyst portion that is in close contact with the ignition heater 3 is heated.
同時に混合ガスを噴射するノズル１２は着火スイッチ５
の操作と連動して触媒層２に近づき、これより混合ガス
は着火ヒータ３と接触した触媒部に集中的に供給される
ため、触媒の単位体積当りの発熱量が大きくなり、着火
ヒータ３と接触した触媒部の温度上昇がすみやかとなる
もので、よって、着火が容易かつ確実となる。The nozzle 12 that injects the mixed gas at the same time is the ignition switch 5
As the mixed gas approaches the catalyst layer 2 in conjunction with the operation of the ignition heater 3, the mixed gas is intensively supplied to the catalyst part that has come into contact with the ignition heater 3, so the calorific value per unit volume of the catalyst increases, and the ignition heater 3 and The temperature of the contacting catalyst portion increases quickly, and ignition becomes easy and reliable.
着火し触媒層２の温度が上昇し、燃焼筒１の温度が上昇
し示温材１５が変色し着火完了を確認する。The ignition occurs, the temperature of the catalyst layer 2 rises, the temperature of the combustion cylinder 1 rises, and the temperature indicating material 15 changes color, confirming completion of ignition.

ざける（第２図の状態）。After checking the ignition, operate the ignition switch 5 and turn on the ignition heater 3.
At the same time, the nozzle 12 is moved away from the catalyst layer 2 (the state shown in FIG. 2).
するとノズル１２から噴射された混合ガスは触媒層２に
均一に供給され、触媒全体で燃焼する。Then, the mixed gas injected from the nozzle 12 is uniformly supplied to the catalyst layer 2 and is combusted in the entire catalyst.
したがって、触媒が部分的に異常温度上昇し、触媒の寿
命を損うようなことはない。Therefore, there is no possibility that the temperature of a portion of the catalyst may rise abnormally, thereby impairing the life of the catalyst.
第３図に、ある条件におけるノズル１２と触媒層２の距
離と着火時間の関係を示す。FIG. 3 shows the relationship between the distance between the nozzle 12 and the catalyst layer 2 and the ignition time under certain conditions.
例えば、４秒以内に着火時間を設定したいときには、着
火時（第１図の状態）の状態で距離を７πｍ以内にする
必要がある。For example, when it is desired to set the ignition time within 4 seconds, it is necessary to keep the distance within 7πm at the time of ignition (the state shown in FIG. 1).
このように、本発明によれば着火とヒータの操作と連動
して、ノズルを移動させ、着火時のみ着火ヒータと接触
