を防ぐようにしたものである。2. Description of the Related Art A combustion catalyst mainly intended for use in a boiler has been proposed (for example, see Japanese Patent Publication No. 47262/1990). This prior art has been proposed with a focus on the fact that the catalyst is likely to be degraded by heat of combustion when used under high load conditions, and a flow path having catalytic activity and a flow path having no or little catalytic activity are arranged adjacent to each other. Thus, heat can be exchanged between the two flow paths, specifically, through a wall separating the two flow paths, so that deterioration of the catalyst is prevented.

うな従来の燃焼触媒体では、原理的に優れた技術が提案
されていたにもかかわらず、本発明者の知りえる範囲で
は具体化・実用化に適する技術が未だ提案されていない
ように思われる。それには幾つかの理由が考えられる。
例えば、触媒の担持方法が難しく、目的とする触媒構造
が得難く、全ての部分において完全なる熱交換関係が成
立せず、長時間の高温燃焼で触媒が痛みやすいという
点、更にはファンヒータに用いられる一般的な燃焼機器
へ組み込むための全体設計が難しい点等が挙げられる。However, in spite of the fact that excellent techniques were proposed in principle in such a conventional combustion catalyst, the present invention has been embodied and put into practical use as far as the inventor can know. It seems that no suitable technology has been proposed yet. There are several reasons for this.
For example, the method of supporting the catalyst is difficult, the target catalyst structure is difficult to obtain, the complete heat exchange relationship is not established in all parts, and the catalyst is easily damaged by prolonged high-temperature combustion. The point is that it is difficult to design an overall design for incorporation into a general combustion device used.

極めて大きな欠点となる。[0004] In the combustor for the fan heater, it is also possible to use a catalyst having an opening degree of the catalytic combustion passage of 100%. However, when a catalyst having an opening degree of 100% is used,
Since catalytic combustion occurs on the entire surface on which the catalyst is supported, the temperature tends to rise, and the temperature must be controlled. This is addressed by increasing the amount of air mixed with the combustion fuel and diluting the combustion fuel. For this purpose, it is necessary to increase the capacity of the blower fan, and the noise generated by the blower fan increases. This is a very serious drawback in selling the fan heater as a product.

The focus was on how to efficiently construct the structure, and how to design the entire combustion catalyst.

With a corrugated foil,
Next, a wash coat is applied to the entire surface, and a solution containing a noble metal component as a catalyst is further applied thereon, followed by heat treatment to form a catalyst foil carrying the noble metal component,
The catalyst foil is wound and housed in a cylindrical case, and a primary-side catalytic combustion passage having a catalyst foil and a secondary-side gas-phase combustion passage having no catalyst passage are continuously provided inside the cylindrical case. Further, the degree of opening of the catalytic combustion passage with respect to the entire area of the primary-side inlet opening is adjusted to 50% or less, preferably 35% or less.

によって放散され触媒の過熱制御が行なわれる。[0007] According to this method for producing a combustion catalyst, the catalyst is carried via the wash coat applied to the surface after aluminum oxide is formed on the surface, so that the catalyst has good fixation to the corrugated foil, and the catalyst foil can be used. In the state of being wound up and housed in a cylindrical case, the waveform that becomes a so-called tortuous path due to the herringbone shape is alternately superimposed and adjacent, so in the passage where the catalyst exists, the combustion air contacts the catalyst sufficiently and burns At the same time, the heat of the catalyst is dissipated by efficient heat exchange with the passage in which no catalyst is present, and the overheating of the catalyst is controlled.

約１０％程度のものである。Further, by providing a catalytic combustion passage on the primary side and a gas-phase combustion passage on the secondary side in the direction of flow of the combustion air, unburned fuel passing through the primary-side catalytic combustion passage is reduced. Since the fuel is combusted in the secondary gas phase combustion passage, the combustion efficiency can be increased. Further, in addition to the improvement of the combustion efficiency and the heat exchange function of the catalyst utilizing the herringbone shape, the opening degree of the catalyst combustion passage with respect to the entire area of the primary inlet opening is 50% or less, preferably 35% or less. By adjusting the temperature to, a synergistic temperature control function for the catalyst can be expected, so that the overall design for incorporating this combustion catalyst into the combustion equipment becomes easy. Here, "Opening degree is 50% or less,
Since "preferably 35% or less" is the ratio of the cross-sectional area of the catalyst body to the catalyst combustion passage carrying the catalyst, a certain measurement error may occur. This measurement error is about 10%.

ないことが分かる。Further, in order to reduce the volume of the blower fan and reduce the noise generated, a high-temperature combustion catalyst that can be used in a high-temperature region as described in the present invention, which requires a small amount of blown air, is used. There is a need. In the present invention, the effect of adjusting the opening degree of the catalytic combustion passage to 50%, preferably 35% or less is clear from FIG. It is difficult to use a catalyst having an opening degree of 100% for a long period of time in a region exceeding the adiabatic combustion temperature of 950 ° C. at any linear velocity. This is because it is necessary to consider the required life of the fan heater. On the other hand, as a result of adjusting the opening degree of the catalytic combustion passage to 50% and 35%, it can be seen that combustion in a high temperature region becomes possible as compared with the opening degree of the catalytic combustion passage of 100%. Considering the region where the catalyst is damaged and deteriorated and the region where carbon monoxide CO is generated, in the case of the opening degree of 50%, the area surrounded by the lines (C) and (D) in the drawing, the opening degree of 35% In the case of%, it can be used in the area surrounded by the lines (A) and (B) in the figure. In addition, the use of the combustion catalyst of the present invention enables long-term stable use. The “Current fan heater operating range” in the figure
Indicates an operation range for achieving the amount of generated heat required for the conventional burner type fan heater. Therefore,
It can be seen that in order for a fan heater using a combustion catalyst to meet this condition, operating conditions in this region must be ensured.
