ることが課題となつていた。 A rotary furnace is a small rotary furnace, and a gas burner is inserted into the rotation center of the rotary furnace as a heating device. Conventional gas burners usually have one burner nozzle oriented perpendicular to the burner axis. Because it is held vertically upward, it has the effect of heating the inner wall of the rotary furnace, but the heat transfer ability to the sample layer is low, and a sufficient heating rate and temperature cannot be obtained, and the required combustion amount becomes large. Yes, especially the width (distance between inner walls)
In the case of a rotary furnace with a small diameter and a large inner diameter, this disadvantage is significant, and the challenge has been to maximize the flame area with respect to the sample surface and increase the amount of heat transferred to the sample layer.
本発明は、前記問題点を解決するために創案さ

ツトできるようにしている。 Figures 1 and 2 show the configuration of a gas burner. In the figures, 1 is the burner body, and the tip is symmetrically positioned at a constant elevation angle of, for example, 10° to 20° (as shown in the figure). θ), two sets of left and right burner nozzles 2 are provided at intervals in the direction of the burner axis, and rotary joints 3 and 4 are provided at the base end.
A fuel supply pipe 5 and an air or oxygen supply pipe 6 are connected through the rotary joints 3 and 4, respectively, and a mounting seat 7 and an angle positioner 8 are provided on the distal side of the rotary joints 3 and 4. The burner body 1 penetrates through the center of rotation of the furnace wall 9 and its tip is inserted into the furnace 10, and is rotatably attached to the furnace wall 9 via the mounting seat 7 so that the burner nozzle 2 is inserted into the furnace. It is set at the inner center, and the angle of the burner nozzle 2 can be adjusted and set as appropriate via an angle positioner 8.

成する。 FIGS. 3 and 4 show the situation during the sample firing experiment using the rotary furnace as described above. To explain the method of use with reference to both figures, when a sample 12 is charged into the furnace 10 surrounded by the inner surface 11 of the furnace wall and the rotary furnace is driven to rotate, the sample surface 13 is tilted high in the direction of rotation and the sample 12 is It is stable at an angle of repose of . Do not direct the burner nozzle 2 toward this sample surface 13.
After adjusting the rotation of the burner body 1 via the angle positioner 8 so that the symmetry line L of the left and right burner nozzles 2 is perpendicular to the sample surface 13, the flame 14 is formed via each burner nozzle 2. At this time, since the burner nozzle 2 faces on the side opposite to the sample surface 13 and on both left and right sides, a plurality of flames 1
4 forms the maximum flame front parallel to the sample surface 13 that covers the sample surface 13 without directly affecting it.
なお、試料面１３と平行な火炎面を形成するた
めにはバーナノズル２に仰角を付けなくてもよ
い。 Incidentally, in order to form a flame surface parallel to the sample surface 13, it is not necessary to give the burner nozzle 2 an elevation angle.

る。 As described above, the present invention uses a gas burner that is rotatable around the axis and is equipped with one or more sets of burner nozzles symmetrically oriented in the direction perpendicular to the direction of the burner axis. The effectiveness of the flame surface is maximized, and the required amount of heat transfer, in other words, the ability to raise temperature, can be obtained with a smaller amount of combustion.
