Generally, a flame has a temperature distribution along the flame axis, and when heating using a flame, it is difficult to avoid the influence of this temperature distribution. For example, the first
As shown in the figure, when a plurality of heated objects 3' are heated with a single flame 4', this effect becomes noticeable.
The object to be heated 3' near the burner 2' has the highest temperature, and as it moves away from the burner 2', the temperature tends to decrease gradually, making uniform heating extremely difficult. The present invention
A heating device for a fan-shaped furnace that solves these problems will be described below with reference to the drawings.
In FIG. 2, reference numeral 1 denotes a fan-shaped furnace, and a burner 2 is arranged near the center of the furnace 1. The object to be heated 3 is arranged at approximately the same distance from the burner 2 and on the same arc. The burner 2 is configured to generate a number of flames 4 equal to the number of objects to be heated 3, and each flame 4 is directed to the upper part of each object to be heated 3, and the burner 2 is configured to generate flames 4 in a number equal to the number of objects to be heated 3. 5 is configured to have an exhaust hole 6. The burner 2 may have a structure in which, for example, a plurality of independent burners are bundled into one burner. In this case, each burner is independent in terms of combustion, so
The combustion amount can be adjusted for each burner.
Therefore, multiple flames 4 generated from the burner 2
reaches the upper position of each object to be heated 3 and circulates in the furnace so as to cover each object to be heated 3. At this time, the exhaust gas is discharged from an exhaust hole 6 provided in the hearth 5 near the object 3 to be heated.

することができる等優れた特徴がある。 Since the present invention is as described above, in particular, it not only eliminates the temperature difference in the vertical direction inside the furnace, but also makes the temperature distribution uniform overall, prolonging the life of the furnace, and The positional relationship is the same for all objects to be heated, and the influence of the heat received from the flame is also the same, making it possible to achieve uniform heating. In such a case, for example, when the object to be heated is a crucible for glass melting, the crucible is uniformly heated, so its life can be significantly extended. In addition, multiple exhaust holes are provided in the hearth near the fan-shaped arc far from the burner, which ensures that the flow of combustion gas is the same no matter which object is being heated, promoting even more uniform heating. It has excellent features such as being able to
