These compressed air jet nozzles 38 are arranged around the nozzle cone 16, project in the extension direction of the flame A radiated from the nozzle 15, and are inclined in the outer peripheral direction of the flame A. That is, the plurality of compressed air ejection nozzles 38 are inclined so as to converge toward the center of the flame A toward the tip side.

The compressed air supply pipe 36 is connected to the pipe 39.
Is connected to a compressed air supply device 40 such as a compressor via an air pressure adjusting valve 41.

According to the burner device of the cremation furnace constructed as described above, the casket containing the body is introduced into the combustion chamber 2 from the entrance 3 by the cremation cart or the like and placed on the casket mounting table.
When the open / close door 4 is closed and the swing burner 14 is ignited, the flame A generated from the nozzle 15 of the nozzle cone 16 is injected toward the front of the combustion chamber 2 to cremate the casket.

At this time, compressed air is supplied from the compressed air supply device 40 to the annular groove 35 of the nozzle support ring 34 through the pipe 39. The compressed air is ejected from a plurality of compressed air ejecting nozzles 38, and the compressed air is ejected so as to wrap the flame A radiated from the nozzle 15 and in the radial direction thereof. Therefore, the flame A is a linear and sharp flame. Head to the casket as the burned material. Therefore, the entire casket can be wrapped with the flame A, and not only the combustion near the swing-type burner 14 but also the efficient combustion becomes possible.

During the cremation with the flame A generated from the nozzle 15 of the nozzle cone 16, that is, when the cremation has progressed to a certain degree, the state of the casket is monitored from the monitoring window (not shown), and the direction of the flame A is changed vertically and horizontally. If it becomes necessary to move to, perform the following operation.

First, in order to move the swinging burner 14 in the vertical direction, the operating handle 29 is rotated clockwise to screw the threaded portion 28 of the operating rod 27 into the guide nut 24. The lower end is pulled backward.

Since the upper end of the vertical rocking plate 10 is rocked forward about the pivot shaft 13 by about 15 °, the swing burner 14 is rotated downward and the flame ejected from the nozzle 15 is blown. A is also diagonally downward. Of course, at this time, the compressed air jet nozzle 38 also rotates integrally with the swing type burner 14, so that the flame A radiated from the nozzle 15 is wrapped.
Moreover, the flame A spouts in the radial direction and goes toward the casket with a linear and sharp flame.

Further, by rotating the operation handle 29 counterclockwise to unscrew the threaded portion 28 of the operation rod 27 from the guide nut 24, the swinging burner 14 can be moved upward by the action opposite to that described above, but the combustion chamber can be moved upward. The purpose is to direct the flame A to the remnants of incomplete combustion in 2, and the upward movement of the swing burner 14 is hardly necessary.

On the other hand, when the swing type burner 14 is moved in the left-right direction, the rear end portion of the swing type burner 14 is moved to the right side so that the left-right swing plate 9 moves leftward about the pivot shaft 12. The upper and lower oscillating plates 10 oscillate in the same direction integrally with the left and right oscillating plate 9 as they oscillate at about 15 °, and the flame A ejected from the nozzle 15 also becomes diagonally leftward. Of course, at this time, the compressed air jet nozzle 38 also rotates integrally with the swing type burner 14, so that the flame A radiated from the nozzle 15 is jetted toward the radial direction, and the flame A is linear. And head for the coffin with a sharp flame.

Further, by moving the rear end of the swing-type burner 14 to the left side, the left and right swing plate 9 swings about the pivot shaft 12 to the right by about 15 °, and the left and right swing plate 9 and The vertical swing plate 10 swings integrally in the same direction, and the flame A sprayed from the nozzle 15 also faces diagonally right.

In this way, the nozzle 1 of the swing type burner 14
5, the direction of the flame A injected from 5 up and down inside the combustion chamber 2,
The air can be oscillated in the left-right direction, and further, the air ejected from the compressed air ejection nozzle 38 is ejected in the radial direction so as to wrap the flame A emitted from the nozzle 15, and the flame A is linear and sharp. Head to the casket with a nice flame.

Therefore, the normal burner regulates the combustion amount by adjusting the fuel supply amount and the air amount, and the state of the flame is determined by the burner ability, but the flame that is about to be spread by the compressed air is linear and sharp. Can be flame.

[0031]

As described above, according to the present invention, by swinging the left and right swing plates, the swing type burner integrally swings in the left and right direction via the up and down swing plates, By swinging the vertical swing plate, the swing-type burner swings vertically in unison with this.

Since a plurality of compressed air jet nozzles are provided around the burner so as to project in the extension direction of the flame radiated from the nozzle and are inclined in the outer peripheral direction of the flame, the compressed air jetted from the compressed air jet nozzle is provided. Envelops the flame radiated from the nozzle and ejects it in the radiating direction, so that the flame is a linear and sharp flame that is directed toward the burned material and can be efficiently burned.

Therefore, there is no need to use wasteful work to move the incompletely burned debris to the place where the flame is hit by the wrench, and there is an effect that the combustion efficiency is improved and the economy is achieved.
