Abstract

PROBLEM TO BE SOLVED: To obtain excellent heat resistance and durability by forming a plate of heat resistant allayed metal foam of a material opened with a plurality of burner ports each having a diameter of a specific size range, thereby stabilizing a flame and reducing NOx. SOLUTION: The burner element 7 is formed of a material obtained by heat resistant alloying (adding Cr, Al by thermal diffusion penetration) a plate of metal foam. Burner ports 7a each having a diameter of 0.5 to 2.0mm are opened at an interval of 2.5 to 10.0mm at the plate, and the plate is cut in necessary shape and size to the element 7. Thus, the thus formed element 7 has less irregularity of pore size, pore shape and pore distribution as compared with metal nonwoven fabric, and hence combustion is stabilized and NOx generating amount is reduced even if a method of enhancing gas and air supply pressures is not used. Accordingly, the surface combustion burner having low environmental pollution, a compact structure, easy handling, and excellent heat resistance, durability can be obtained by a low cost.

2. Description of the Related Art Various kinds of materials are already used for burner elements of surface combustion burners. Among them, a plate-like element which is frequently used is made of a ceramic material capable of withstanding a combustion temperature and has a flame hole formed on one surface. This is because the ceramic itself ignites and emits infrared rays, and the entire ceramic plate emits radiant heat together with the radiant heat of the gas flame, so that a planar heating portion is obtained.

In addition, since ceramic burner elements are liable to cracks and the like due to a heat cycle and have a problem in durability, recently, a nonwoven sheet of metal fiber is used, and gas is burned by permeating the sheet. In addition, a burner element in which the entire nonwoven fabric becomes a planar heating element is also used.

An essential property of a burner element for a surface combustion burner is that a flame is stably generated over the entire surface. However, a burner element made of a non-woven metal fabric is capable of controlling the intensity of the flame. In some cases, flames are not generated cleanly on the entire surface, and there is a possibility that a misfired portion may be formed. In addition, an abnormal temperature rise exceeding the heat resistance limit of the metal fiber may be a concern. To solve this problem, a technique has been proposed in which a flame hole is provided in a metal nonwoven fabric sheet so that a flame remains without misfiring even in the event of strong combustion, thereby maintaining a stable ignition state and preventing an abnormal temperature rise. But
There is a limit to flame stabilization due to this.

[0005] Metallic nonwoven fabrics do not always have uniform gaps (pores) in the overlapping portions of short metal fibers. Due to the manufacturing process, the distribution of pores and the shape of pores also vary. Gas is sent to the surface through these pores, so if a more stable flame is required, measures such as increasing the supply pressure of fuel gas and combustion air are required, and costs and burner size etc. Will be affected. In addition, the metal nonwoven fabric has a surface on which the effect of reducing NO X is not sufficient.

Here, the starting material (material before alloying) is a Ni-based metal foam plate manufactured by Sumitomo Electric Industries, Ltd. {trade name: Celmet # 7 (# 7 is a product number, 1 inch (Indicating that the number of cells crossing the length is 50 to 70). This metal foam is obtained by subjecting a resin foam to a conductive treatment, applying a Ni plating to the skeleton surface of the foam, firing (the resin is incinerated at this stage) and reducing the Ni foam. Since the pore diameter of the original resin foam is nearly uniform and has little variation,
The resulting metal foam also has a very small deviation in the pore size distribution. Several metal foams are stacked and pressed to a predetermined thickness. Celmet # 7 has an original thickness of 1.6 mm. Therefore, in order to secure the required thickness, several sheets are stacked and compressed to 3/4 to 1/3 of the original thickness to obtain appropriate strength and bulk density.

Further, if this plate is used as it is, a flame which wraps the entire surface of the element evenly cannot be obtained. Therefore, a flame hole having a diameter of 0.5 to 2.0 mm is formed on the plate.
At a distance of 0.0 mm, this plate is cut into a required shape and size to form a burner element 7.

It is conceivable that the flame hole 7a may be of a combination of two types, large or small, or that the diameter of the periphery and the center of the element may be changed. It is easier and more advantageous to make the holes at the same pitch. The pitch and arrangement of the flame holes depend on how the elements are used, but there is no particular problem if the holes are arranged in a grid pattern.
