どに開示しであるが、主燃焼室よりガスを排出する煙道
を、炉の後壁寄りに設けたものが知られている。In a conventional crematorium equipped with a main combustion chamber and a reburning chamber, the coffin is placed on a trolley and inserted into the main combustion chamber from the previous day, and the coffin is cremated using the flame jet from the main burner installed on the rear wall. The unburned gas generated in the combustion chamber is sent to the reburning chamber through a flue opened near the front wall of the main combustion chamber, where it is reburned and exhausted through the chimney. In addition, other formats include Utility Model Application Publication No. 15340 of 1930, Publication No. 15340 of 1933,
As disclosed in Japanese Utility Model Publication No. 19472 and Japanese Utility Model Application Publication No. 54-66482, it is known that a flue for discharging gas from the main combustion chamber is provided near the rear wall of the furnace.
上述の何れの形式の炉であっても、火葬を始めた当初、

がある。Regardless of the type of furnace mentioned above, when cremation first began,
The wooden part of the coffin that is directly hit by the flame burns to a degree close to complete combustion, but other parts of the coffin start to burn due to the heat of combustion, emitting a lot of black smoke, and the unburned gas is combusted in the reburning chamber. However, the amount of unburned gas generated is larger than the processing capacity of the reburning chamber, and there is a drawback that it is discharged untreated.

たるように工夫したもので、燃焼ガスの滞炉時間が長く
燃焼効率上有利であるが、熱が柩の表裏両面に当たるた
め、火葬の当初に発生する黒煙の量が更に多くなること
から、主燃焼室の後壁に煙道を設ける形式のものを採用
することが出来ない現状であった。Moreover, the crematorium described in each of the above publications is of the Rosdle type, and is designed so that the heat of combustion is directly applied to the ashes tray installed below the Rosdol, which increases the residence time of the combustion gas in the furnace and increases the combustion efficiency. Although this is advantageous, since the heat hits both the front and back of the coffin, the amount of black smoke generated at the beginning of the cremation increases, so a type with a flue installed on the rear wall of the main combustion chamber is recommended. The current situation was that it was not possible.
本発明は以上の問題から、主燃焼室の後壁に煙道を設け
る形式の炉の有利さを利用し、しかも黒煙の発生量を減
少することが出来る火葬炉を提供することにある。SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a crematorium that utilizes the advantages of a furnace in which a flue is provided on the rear wall of the main combustion chamber and that can reduce the amount of black smoke generated.

燃焼室の主バーナーを設けた後壁寄りに再燃焼室へ通じ

う空気噴出口を備えるものである。The solution according to the present invention is a crematorium equipped with a main combustion chamber and an afterburning chamber, and is intended for a trolley-type furnace. A flue leading to the fire door is provided, and an air outlet directed toward the rear wall is provided at the top of the front wall provided with the fire door.

が混入し燃焼を促進するものである。As is well known, the main burner used in a crematorium is one that can adjust the flame length to shorten or shorten.When cremating the coffin, the coffin can be burned from the end closest to the main burner to the other end, and the air is ejected from the air outlet. Since the airflow is directed toward the rear flue, the generated gas is guided to the flue, and the heat does not affect the unburned parts of the coffin, so the amount of black smoke generated is slightly controlled. Ru. Furthermore, the air injected into the generated unburned gas is mixed to promote combustion.

になっている。To specifically explain the crematorium according to the present invention, as shown in the drawing, a front hall l and a workshop 2 are separated by a decorative layer 3, and a crematorium is installed in the workshop 2 in a continuous manner with a morgue 4. The crematorium is equipped with a main combustion chamber 5 at the bottom and a reburning chamber 6 at the top. The carriage 7 is introduced from the chamber 4 into the main combustion chamber 5 by a transfer device 9.

１３間に再燃焼室６内へ通じる煙道１７を設けている。The front wall 10 of the main combustion chamber 5 has an inlet 12 that is opened and closed by a fire door 11 that moves up and down, and the rear wall 13 is provided with a main burner 14.
A pocket portion 15 into which the tip end of the cart 7 is inserted is provided. Furthermore, a hanging wall 16 is installed closer to the rear wall 13 than the earthen wall of the furnace.
A flue 17 is provided between the hanging wall 16 and the rear wall 13 so as not to touch the coffin, and leading into the afterburning chamber 6.

On the other hand, a plurality of air jet ports 19 are provided above the inlet 12 of the wall 10 so that air is jetted toward the rear wall 13. Further, an auxiliary burner 20 is provided on the rear wall of the afterburning chamber 6, and an exhaust port 21 leading to a chimney (not shown) is opened on the front side of the ceiling wall.

．． 23 and fuel introduction pipes 24 and 25 are connected via controllers 26 and 27, respectively, and the air introduction pipe 28 is connected to a timer 29, which bypasses the pipe 18 in the hanging wall 16 and inserts air into the air outlet 19. The valve opening/closing device 30 is connected to the valve opening/closing device 30. In FIG. 1, the arrow a shown on the air introduction pipe 28 is for guiding the air to the inlet of the pipe 18 in the hanging wall 16, and the arrow a is for guiding the air from the outlet of the pipe 18 to the air outlet 19.

In the state where air is injected from 9, the main and sub-side burners 1
4.20 is ignited, the tip of the coffin is first burnt with a short flame, and the flame progresses to the other end one by one, burning the wood of the coffin. After that, the amount of air jetted from the air outlet 19 is controlled to carry out the main cremation. It is something to do.

して省エネルギー化を計ることが可能となる。The crematorium according to the present invention has a flue near the rear wall of the main combustion chamber and an air outlet at the top of the front wall, so when burning a coffin, the burner moves the coffin from one end to the other. It is now possible to burn the coffin in sequence, and when it is burned in sequence, the heat of combustion does not reach the unburned parts of the coffin, so almost no black smoke is emitted and the coffin is burnt in a state close to complete combustion. Moreover, since air is mixed into the generated unburned gas, combustion is further promoted, and the processing load in the re-combustion chamber is reduced, making it possible to save energy.

。Furthermore, during the actual cremation, the gas generated does not immediately flow into the re-combustion chamber, but instead remains at the top of the main combustion chamber, during which time the gas is combusted, resulting in almost complete combustion within the main combustion chamber. The resulting heat can shorten the cremation time.
