Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cremation furnace provided with a main combustion chamber having a main combustion burner and a reburning chamber having a reburn burner. The present invention relates to a cremation furnace in which an insertion opening of a flue for guiding generated unburned gas to a reburning chamber is opened at an upper portion of the main combustion chamber near a main burner.

[0002]

2. Description of the Related Art A main combustion chamber has a vertically long space for accommodating a vertically long casket, has an opening with a fire door at one end in the longitudinal direction, and a main combustion burner at the other end. When the coffin is installed in the main combustion chamber, the front end face of the coffin is close to the main burner, and at the beginning of the cremation, the flame of the main burner is weakened and cremation is started. It is most preferable to cremate the flame by intensifying the flame from the time when a part of the front end face is burned and the flame is injected into the coffin, and it is instructed to perform the above operations for the cremator Things.

[0003]

However, in practice, this is not the case. In order to start cremation with a stronger flame than at the beginning of the cremation, not only the fuel is wasted but also the plate at the front end face of the coffin is particularly damaged. In general, it is 3-5 cm thick,
The combustion takes a relatively long time (generally 4 to 6 minutes), and if the fuel is oil, the injected oil adheres to the front end of the coffin without burning and emits black smoke. , Because a heavy burden is imposed on the combustion process in the reburning chamber,
Before starting the cremation, it is necessary to operate the reburning chamber to keep the room temperature high, and thus there is a problem that a large amount of fuel is consumed.

The present invention has been made to solve the above problems, and even if cremation is started with a stronger flame than at the beginning of the cremation, the generation of black smoke is suppressed as much as possible, and the strong flame can be consumed for burning the coffin without waste. It is in.

[0005]

A solution according to the present invention is that a hollow portion is provided over the entire length of the main combustion chamber on one side of a portion where the coffin is installed in the main combustion chamber, and the main combustion burner is provided with the cavity. In addition to being provided at a position facing the hollow portion, the main burner is provided so as to be able to swing up and down and left and right.

[0006] As described above, the means for providing the hollow portion is formed in such a manner that the width of the main combustion chamber is made slightly wider than that of the conventional one, and the width is the same as that of the conventional one. There is a case where the inner surface of the side wall is cut out in a groove shape that is open on the inner side of the main combustion chamber over the entire length.

Further, the main burner can be supported so as to be able to swing up, down, left and right by a conventionally known universal joint.

[0008] A modified window is provided on the rear wall of the main combustion chamber on the side where the main burner is provided, facing the front end surface of the coffin installed in the main combustion chamber.

As described above, the main burner is provided on the rear wall facing the front end face of the coffin so as to be shifted to one side, so that the modified window can be provided on the rear wall so as to face the front end face of the coffin. , Since that part is almost in the center of the rear wall,
It is possible to accurately grasp the front, rear, left and right of the position to be inspected at the time of inspection during cremation, and can be opened larger than the conventional modified window, making it easier to modify during cremation It is.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described by way of an embodiment. As shown in FIGS. 1 to 3, a main combustion chamber 2 is provided at a lower part of a furnace body 1, and a re-combustion chamber 3 is provided at an upper part thereof. The main combustion chamber 2 has a vertically long space in which a vertically long coffin H is placed on a trolley 4 and fits therein. The main combustion chamber 2 is opened and closed by a fire door 6 on a front wall 5 at one end in the longitudinal direction. Entrance 7
And a main burner 9 and a modified window 10 are provided on the rear wall 8 on the opposite side. Further, an insertion opening 12 of a flue 11 is opened at an upper portion near the rear wall 8 of the main combustion chamber 2, and the flue 11 communicates with the reburning chamber 3. A flame from a reburning burner 13 provided above the rear wall 8 is injected into the reburning chamber 3, and gas is discharged from a smoke stack 14 to the atmosphere.

The main combustion chamber 2 is formed such that the width thereof is wider than the conventional width, that is, in a state where the coffin H is installed in the main combustion chamber 2, the cavity 15 is mainly formed on the side of the coffin H. Combustion chamber 2
Is formed so as to be able to be formed over the entire length.

On the other hand, a main burner 9 provided on the rear wall 8 is
As shown in FIG. 1, it is mounted so as to face the hollow portion 15, and the mounting means is a universal joint. Specifically, a bifurcated frame is attached to a rotatable upright shaft 16. The main burner 9 is provided in the frame 17 so as to be able to swing up and down on a horizontal axis 18. Further, from the viewpoint of soundproofing, it is preferable that the main combustion burner 9 be covered with the cover 20.

As described above, the main burner 9 is provided on the rear wall 8 so as to be offset.
Are provided so as to be substantially opposed to the center and toward the center, and have a larger area than the size of the conventional retouching window.

Next, the example shown in FIG.
5 are different from each other in that the width of the main combustion chamber 2 is the same as that of the conventional combustion chamber.
The cavity 15 is provided by notching the inner surface of the main burner over the entire length, and the mounting structure of the main burner 9 and the modification window 10 is the same as that in the above-described example.

As described above, since the hollow portion 15 is provided in the main combustion chamber 2 and the main burner 9 is provided toward the hollow portion 15, the main burner 9 is directed toward the hollow portion 15 during cremation. By operating, the fired flame runs without blasting on the front end face of the coffin H and licks on one side of the coffin H, bends against the fire prevention door 6, and the flue 11 of the main combustion chamber 2 Since the flame is provided near the rear wall 8, the flame runs toward the rear wall 8 through the side of the coffin H opposite to the above, and even if the flame is jetted stronger than at the beginning of the cremation, the flame is generated by the coffin H
Of the casket H is heated to burn around the coffin H, and a part of the unburned gas generated there is burned in the main combustion chamber 2, And it is guided to the reburning chamber 3 through the flue 11. At the time when the coffin H burns and cremates the body, the main burner 9
Is cremated by inclining left and right and up and down.

[0016]

According to the cremation furnace of the present invention, a cavity is provided in the main combustion chamber, and the main combustion burner is provided facing the cavity. The flame from the main combustion burner surrounds the coffin. In the meantime, the casket is cremated by touching the flame, so even if a stronger flame is emitted than at the beginning of the cremation, the casket is burned quickly without causing incomplete combustion, and the time required for cremation And fuel consumption can be reduced.

Further, since the modified window is provided substantially at the center of the rear wall, when checking the cremation state in the furnace, the sense of distance between the front, rear, left and right inside the furnace can be grasped without fail, and the main fuel The burner's flame can be reliably cremated toward the required position, which also promotes cremation and has the effect of reducing time.
