に解決するものである。(Problems to be Solved by the Invention) In the method described above in which a plurality of burners are installed in the furnace body, as the number of burners increases, the number of fuel and air piping increases, and the equipment cost increases. Furthermore, a gas burner incorporating a plurality of gas nozzles has the disadvantage that the width of the burner itself becomes large, and the attachment opening of the furnace body must be made large, resulting in a decrease in the strength of the furnace body. The present invention provides a burner that aims to make the temperature distribution inside an industrial furnace uniform, especially the temperature distribution in the direction perpendicular to the burner axis, and to improve thermal efficiency. It solves all the shortcomings at once.

する構成とする。(Means for Solving the Problem) Reference numeral 1 denotes a burner combustion chamber composed of burner tiles 2, and the ejection port 3 of this combustion chamber 1 is configured in a slit shape, and a flow path 4 leading to the ejection port 3 is provided.
The cross-sectional area is made larger as it approaches the ejection port. Inside the burner combustion chamber 1, a hollow cylindrical flame stabilizer 8 having a collar 5 at one end, a radial gas nozzle 6 at the other end, and a large number of holes 7 is installed.

の偏平炎が発生する。(Function) Therefore, when air is introduced from the air introduction part 9, most of the air is transferred from the hole 7 of the flame holder 8 to the flame holder 8.
At the same time, other air flows into the burner combustion chamber 1 from the outer periphery of the collar 5. On the other hand, the fuel gas is supplied through a radial gas nozzle 6 provided on one side of the flame stabilizer 8.
Fuel gas is ejected radially into the flame stabilizer 8 from the flame stabilizer 8.
Thus, rapid mixing of the fuel gas and air occurs in the flame stabilizer 8, and a flame is generated and ejected into the combustion chamber 1. Such a flame is stably maintained by the recirculation flow generated downstream of the collar 5 by the high-speed air flow flowing around the outer circumference of the collar 5. Therefore, flame holder 8
If the mixture is good, a stable flame will be generated. When the flame in the combustion chamber 1 goes in the direction of the jet nozzle 3, the flow is constricted in the flow path 4, and the flame is ejected from the slit-shaped jet nozzle 3, thereby generating a powerful fan-shaped flattened flame.

果がある。(Effect of the invention) As described above, the present invention can produce a strong fan-shaped flattened flame, so when configuring a burner with a capacity of 80×10 4 Kcal/h, In the burner, the burner tiles 2 that make up the combustion chamber are
The outer diameter dimensions (H x W) of 350 mm x 600 mm have been reduced to 350 mm x 350 mm, making the cross-sectional area about 60% more compact. Furthermore, compared to the configuration with multiple burners shown in Fig. 1, the present invention can make the temperature distribution in the furnace uniform over a wide area with a single burner, as shown in Fig. 4. The number of burners installed can be reduced, which has the effect of reducing burner manufacturing costs and simplifying air and gas piping.
