Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a catalytic burner, and an object of the present invention is to ensure ignition of the burner and to prevent soot from adhering to the burner due to lack of secondary air.

Conventionally, catalytic burners have been developed as gas stoves with new configurations that provide a stronger sense of warmth.
The present invention relates to improvements thereto, and one embodiment of the present invention will be described below with reference to the drawings.

The basic structure of the present invention is that a material having a strong catalytic effect against flammable gases such as platinum, palladium, rhodium, etc. is applied to a thick cotton-like heat-resistant mat made of fibers such as alumina-silica by appropriate means. A burner is installed to carry out a combustion reaction using combustible gas and secondary air on the surface and inner layer of the pine, and in order to further activate the catalytic action at the start of combustion, the entire surface or a portion of the pine is heated in advance to raise the temperature. In a combustion device that has a burner and an ignition burner, part of the flame from the ignition burner is used to transfer the flame to the heating burner, and the remaining flame is guided to the front of the pine to promote activation of the pine surface. This is a catalytic burner equipped with a

As shown in Figures 1 and 2, 1 is an ignition burner, and the flame is radiated toward the flame transfer guide 4, and the remaining part of the flame is radiated toward the mat surface so as to ignite the heating burner 2. is configured to be This ignition burner 1 burns only when the device is ignited, and is extinguished in a steady state. The heating burner 2 helps activate the catalyst mat 5. The heating burner 2 is extinguished after it is confirmed that the catalyst mat 5 has been sufficiently activated and a stable combustion state has been entered. 3 is a holder for the heating burner 2; 4 is a guide for transferring fire to the heating burner seal; 6 is a heat insulating material for the catalyst mat 5; 7 is a wire mesh for holding the catalyst mat 5; and 8 is a casing for the catalyst mat 5.

A indicates the flow of gas to the ignition burner 1, and the supply is stopped when the heating burner 2 ignites and enters steady combustion. b indicates the flow of gas to the heating burner 2,
After the catalyst mat 5 enters stable combustion, the supply is stopped. c indicates the flow of gas to the catalyst mat 5,
After passing through the heat insulating material 6, it reaches the catalyst mat 5.

With the above configuration, the ignition burner not only ignites the heating burner, but also has no heating effect on the catalyst mat.Furthermore, the heating effect is caused by the pilot flame not being radiated directly onto the catalyst mat surface due to the guide, so that the ignition burner does not only ignite the heating burner, but also has no heating effect on the catalyst mat. Second, air flow is not obstructed.

Also, it is possible to prevent soot from adhering to the catalyst mat surface due to lack of secondary air.

Claims (1)

[Claims] 1. A catalyst mat that performs a combustion reaction using secondary air and combustible gas, a heating burner that heats the front surface of this catalyst mat and activates the catalytic action, an ignition burner that ignites this heating burner, and a flame of this ignition burner. A catalyst burner comprising a guide that guides the flame to the heating burner and guides a part of the flame to indirectly heat the catalyst mat surface without being directly radiated onto the catalyst mat surface.
