[Industrial Application Field] The present invention has a combustion chamber in which a crematorium, especially a coffin, can be accessed,
The present invention relates to a crematorium equipped with a reburning chamber and a flue. [Conventional technology] In recent years, technology to make crematoriums smokeless, odorless, and pollution-free has gradually progressed, but as the urban population increases, crematoriums that used to be located in suburban areas and remote areas are now located in urban areas. The number of users is inevitably increasing. Despite this increase in the number of users, cremation work is not carried out late at night, early in the morning, or on Tomobiki Day due to religious customs, and there is no need to plan new crematoriums or close existing ones. If they tried to expand the facility, there would be a lot of opposition from local residents, causing a stagnation in cremation work. For this reason, it is conceivable to increase the number of times the crematorium is used, but the wall structure of the current crematorium is mainly made of refractory bricks, and although it has strong heat resistance, the amount of heat storage is extremely large. Because it is sensitive to sudden heat and cold,
The maximum number of times a crematorium can be used per day is about two times.
That is, during cremation, for example, the furnace wall on the reburning chamber side is sufficiently scorched to store heat, and then the coffin transport cart is carried into the combustion chamber and burned. After the cremation, the furnace wall is cooled down, and then the coffin transport cart is carried out. That is important. If heat is not stored in the furnace walls in advance, incomplete combustion will occur and black smoke will be generated.Also, if the coffin transport cart is to be carried out without cooling the furnace walls, cold air will enter at once when the furnace door is opened, damaging the bricks. This is because the heat and heat may cause discomfort to the bereaved family. However, since the refractory brick furnace walls take a very long time to heat up and cool down, the batch operation efficiency of the crematorium is extremely low, making it difficult to increase the number of times the crematorium can be used per day. In addition, refractory bricks have a large amount of heat storage, and by the time the heat storage effect exerts the radiant effect that contributes to combustion, the cremation has already finished, so the fuel required for this heat storage is almost wasted. There was also the problem of high costs. Furthermore, refractory brick crematoriums require periodic repairs, and dismantling, construction, and especially drying and curing take time.Repairs of furnaces usually require 7 to 15 days or more, and cremation operations cannot be performed during this time. The operating rate of the crematorium was poor, and repair costs were high. In order to solve this problem, the furnace wall of the afterburning chamber was made of ceramic fibers, which was put into production in 2007.
This is proposed in Publication No. 55-34101. [Problems to be solved by the invention] In the above-mentioned conventional technology, only the afterburning chamber has a ceramic wall and the main combustion chamber has a brick wall, so it takes a long time to heat up and cool down the brick wall during the main combustion in cremation. It was time consuming, difficult to increase the number of times of use per day, and difficult to reduce fuel costs and repair costs. Further, in the above-mentioned prior art, since the ceramic fibers are simply continuously provided in the casing, there is a problem that the ceramic fibers easily fall off due to thermal damage. Further, even when the above-mentioned prior art was applied to the main combustion chamber, there was a problem in that the ceramic fibers fell off due to the impact force applied when the coffin was moved in and out by the transfer truck. Furthermore, even if the ceramic fiber is partially damaged, the entire structure must be repaired. Therefore, the purpose of this invention is to provide a crematorium that can be used more frequently per day to increase operating efficiency, reduce fuel costs and repair costs, and prevent heat damage and impact damage to the ceramic walls. do. [Means for Solving the Problems] The present invention provides a combustion chamber into which a coffin can enter and exit and which is provided with a ceramic wall on the inner surface of the casing, and an afterburning chamber that communicates with this combustion chamber and is provided with a ceramic wall on the inner surface of the casing. and a flue communicating with the afterburning chamber, and the ceramic walls of the combustion chamber and the afterburning chamber have a temperature of approximately
It is equipped with a large number of ceramic blocks in which a plurality of laminated and compressed ceramic fibers having a thermal conductivity of around 0.3 Kcal/mhr°C are crimped together with fixing fittings, and each ceramic block is arranged in parallel, and the fixing fittings of the ceramic blocks are It is fixed by welding to the inner surface of the casing. [Example] Hereinafter, an example of the present invention will be described in detail based on the drawings. In Figures 1 to 3, a combustion chamber 1 is provided with a concrete floor 2, and this floor 2
A transport cart 5 on which a coffin 4 is placed moves on the upper rail 3. Reference numeral 6 denotes a door of the combustion chamber 1 through which the transfer trolley 5 can enter and exit. A re-combustion chamber 8 is disposed above the combustion chamber 1 and is communicated with the combustion chamber 1 through a fire guide path 7, in which the exhaust gas from within the combustion chamber 1 is completely combusted. Furthermore, the reburning chamber 8 communicates with a flue 10 via a whirlpool duct 9 . Ceramic wall A of the combustion chamber 1 and reburning chamber 8
is an outer steel plate 11 as a casing and this outer steel plate 1
1 and a ceramic block 12 provided on the inner surface of the ceramic block 1. Ceramic block 12
A plurality of ceramic fiber blankets 13 obtained by layering ceramic fibers containing small amounts of TiO 2 , Cr 2 O 3 and the like in addition to Al 2 O 3 and SiO 2 are laminated and compressed as required. A block-shaped one integrally formed with the fixing fitting 14 can be used. Then, the fixing fittings 14 are fixed to the outer steel plate 11 by a method such as welding, and a large number of ceramic blocks 12 are arranged in parallel to form the ceramic wall A. Incidentally, the ceramic block 12 may be similarly provided on the inner surface of the door 6, and the ceramic wall A may be formed on the entire crematorium, or may be formed on a part thereof. Furthermore, 15 is an asbestos plate, which is appropriately interposed between the outer steel plate 11 and the ceramic block 12 to exhibit a heat insulating effect. The present invention constructed as described above is shown in the following table and 4.

きる。[Table] Since the operating temperature is 1200°C to 1400°C and the thermal conductivity around this temperature is approximately 0.3 Kcal/mhr°C, the ceramic block 12 coated on the inner surface of the outer steel plate 11 of the combustion chamber 1 and the reburning chamber 8 is Ceramic wall A, which is mainly made of
The heat storage time of the ceramic wall A before the transfer truck 5 is carried in and the cooling time of the ceramic wall A after cremation are much shorter than those of a brick wall, and efficient batch operation is possible. For this reason, conventional brick crematoriums, which were used about two times a day,
The ceramic crematorium of the present invention can be used three to four times. Furthermore, the heat storage time of the ceramic wall A is shortened, and unnecessary heat storage can be reduced, resulting in a significant reduction in fuel costs. In addition, the ceramic block 12 is flexible and has a high restoring force, so it is easy to handle, and the block-shaped fixing fitting 14 is simply fixed to the outer steel plate 11 by welding or the like, so it has good workability. The construction period can be significantly shortened, and partial repairs can be easily done late at night, early in the morning, or in one day. Furthermore, ceramic blocks are lightweight, weighing about 50% of traditional brick crematoriums, and have a volume of 12%.
%, the transportation and installation work is reduced, and the safety of the work is increased. In addition, the ceramic block has an adiabatic sound-absorbing property, which reduces burner combustion noise in the furnace and also reduces noise flowing out from the flue 10 to the outside. Furthermore, in the above embodiment of the present invention, a plurality of laminated and compressed ceramic fiber blankets 1 are used.
3 are integrally crimped together by fixing fittings 14 having a U-shaped cross section, and these many ceramic blocks 12 are arranged in parallel on the inner surface side of an outer steel plate 11 which is a casing. The fixing fittings 14 are fixed to the inner surface of the outer steel plate 11 by welding to form the ceramic wall A.
Since each ceramic block 12
The coffin 4 is firmly fixed and integrated by welding the fixing metal fitting 14 and the outer steel plate 11 to prevent it from falling off due to heat damage during long-term cremation. It is highly durable and can withstand the impact force applied when entering and exiting. Furthermore, since the ceramic wall A is constructed by arranging a large number of ceramic blocks 12 in parallel, only the damaged ceramic blocks 12 can be replaced and repaired, so that repair work can be easily performed. [Other Embodiments] Although one embodiment of the present invention has been described above in detail, various modifications can be made within the scope of the gist of the present invention. For example, in the embodiment described above, the combustion chamber 1 and the afterburning chamber 8 are integrated, but as shown in FIGS. 5 and 6, the combustion chamber 1A and the afterburning chamber 8A may be completely separated. good. That is, the combustion chamber 1A is manufactured with only 7 fire guides opened, and the re-combustion chamber 8A, which was also manufactured separately with only 7 fire guides opened, is connected to the fire guide 7 on top of the combustion chamber 1A. Place it on. By using such a separate structure, for example, in the case of major repair of the crematorium, it becomes possible to warp and replace each part, thereby shortening the repair schedule to about one day and improving the operating rate of the crematorium. Incidentally, the ceramic walls A of the combustion chamber 1A and the afterburning chamber 8A are composed of an outer steel plate 11 as a casing and this outer steel plate 1, as in the previous embodiment.
1, and an asbestos board 15 is interposed as appropriate. In the above embodiment, the explanation was given as a cart type, but it is not limited to the cart type, but can also be applied to a roost type. [Effects of the invention] The present invention consists of a combustion chamber into which a coffin can enter and exit and which has a ceramic wall on the inner surface of the casing, a reburning chamber that communicates with this combustion chamber and has a ceramic wall on the inner surface of the casing, and a flue communicating with the combustion chamber, and the ceramic walls of the combustion chamber and the reburning chamber have a temperature of about 1,200°C to 1,400°C.
It is equipped with a large number of ceramic blocks in which a plurality of laminated and compressed ceramic fibers having a thermal conductivity of around 0.3Kcal/mhr°C are crimped together using fixing fittings, and each ceramic block is arranged in parallel, and the fixing fittings of the ceramic blocks are By fixing it to the inner surface of the casing by welding, it is possible to form a crematorium that has fire resistance and low heat accumulation. Therefore, it is possible to increase the number of times the crematorium is used per day and improve the operating rate, and also to reduce fuel costs because wasteful heat storage is no longer required, and to improve workability and reduce construction and repair costs. This makes it possible to provide a crematorium that is highly effective in practice. Furthermore, each ceramic block is firmly fixed by welding the fixture to the casing, preventing heat damage and falling off due to impact, and repair can be easily performed block by block.
