Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cremation furnace having a fire door on the front wall of a main combustion chamber for cremation on a carriage and a main burner on the rear wall.
[0002]
[Problems to be solved by the invention]
Looking at the cremation situation in this kind of cremation furnace, generally the time required to complete the cremation is about 70 to 100 minutes. The breakdown of flammable materials such as spears was incinerated in about 10 minutes from the start of cremation, and the body became a remains in about 60 minutes from the start of cremation, but there are still incombustible materials such as internal organs of the body. It is not cremation, and it takes about 40 minutes for the cremation, which accounts for about 40% of the total cremation time. However, all the flame retardants are ashed, and the ash is generally disposed of without being collected, and it takes too much time for the cremation of such flame retardants, During that time, there was a problem that fuel consumption was also about half of the total consumption. Therefore, the present invention is to solve the above problems.
[0003]
[Means for Solving the Problems]
The solution according to the present invention is to incinerate flame retardants to be incinerated in a cremation furnace having a fire door on the front wall of the main combustion chamber to be cremation on the carriage and having a main burner on the rear wall. The auxiliary combustion chamber having a required volume is provided in a state of projecting from the side wall of the main combustion chamber to the outside of the main combustion chamber and continuing to the main combustion chamber, and an auxiliary burner is provided in the auxiliary combustion chamber.
[0004]
Moreover, the auxiliary burner is preferably provided on the top wall of the auxiliary combustion chamber.
[0005]
[Action]
As described above, the auxiliary combustion chamber is continuously provided in the main combustion chamber, so the unburned flame retardant left in the final stage of the cremation is transferred to the auxiliary combustion chamber with a derrick and incinerated with an auxiliary burner. In this case, since the amount of the flame retardant is about 2 to 5 g on average, a small volume corresponding to the amount of the auxiliary combustion chamber is sufficient, and it is possible to cremate with such a small volume. In addition, since the auxiliary burner can be brought close to the flame retardant, the cremation can be completed quickly even for the flame retardant.
[0006]
In addition, although the work of transferring the flame retardants of the corpse as described above is a matter of dignity of the corpse even though it is not known to the bereaved, unlike the remains, they are all ashed and not collected, and the reverse Because the time of cremation will be shortened, it will be a cremation method allowed by the bereaved family.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described by way of an embodiment. As shown in FIGS. 1 and 2, a recombustion chamber 2 is provided on a main combustion chamber 1 in which a carriage 3 is inserted and cremation is carried out. 4 is provided with a fire door 5, a rear wall 6 is provided with a main burner 7 and a rear view port 8, and a structure in which a reburner 2 is provided with a sub-burner 9 is different from a conventional cremation furnace. The auxiliary combustion chamber 11 protrudes from the one side wall 10 of the main combustion chamber 1 toward the outdoor side.
[0008]
More specifically, the opening portion 12 is provided on the side wall 10 of the main combustion chamber 1, and the lower surface thereof is provided at substantially the same height as the upper surface of the carriage 3. The auxiliary combustion chamber 11 is formed by being surrounded by the top wall 13, the bottom wall 14 and the peripheral wall 15. Moreover, since the volume of the auxiliary combustion chamber 11 is for cremation of only the flame retardant, it is sufficient that the volume is about 0.03 to 0.1 m ³ .
In addition, it is a good idea to set the auxiliary combustion chamber 11 at a substantially central portion in the front-rear direction of the main combustion chamber 1. However, the auxiliary combustion chamber 11 is not necessarily limited to the center, and is slightly closer to the front side or rear side than the central portion. Although it may be provided, it is not necessary to provide it extremely near the fire door 5 or the main burner 7.
[0009]
The auxiliary burner 16 is installed on the top wall 13 of the auxiliary combustion chamber 11 constructed as described above so that the radiating flame faces the bottom wall 14. However, the auxiliary burner 16 is not limited to the top wall 13 and may be attached to the rear side or the front side of the peripheral wall 15.
[0010]
Further, a side viewing port 17 is provided on the side wall 10 facing the opening 12 of the main combustion chamber 1 so that the combustion state of the auxiliary combustion chamber 11 can be observed.
[0011]
【The invention's effect】
According to the cremation furnace according to the present invention, an auxiliary combustion chamber that protrudes outward from the main combustion chamber and continues to the main combustion chamber is provided, and the auxiliary combustion chamber is provided with an auxiliary burner. Since the flame-retardant material in the cremation body is taken out and provided so that it can be cremation separately from the cremation body, the volume in the auxiliary combustion chamber should be small enough to cremate the flame-retardant material. Since it is processed in such a small room, the temperature rise efficiency in the room is increased, and the impact force due to the flame of the auxiliary burner is increased, so that the incineration time is performed in the conventional main combustion chamber. This is a significant reduction compared to the time required for
[0012]
If an auxiliary burner is provided on the top wall of the auxiliary combustion chamber, the impact force of the flame on the flame retardant can be further increased, and the flame retardant can be quickly processed without being carbonized. .
