The example shown in FIG. 1 is a cremation furnace provided with a main combustion furnace a for cremation of a dead body and a recombustion furnace b for burning gas generated in the main combustion furnace a.

＜再燃焼炉＞
前記再燃焼炉ｂは、その前方に位置し再燃焼の初期及び中期の工程が行われる前期交流室Ｘと、その後方に位置し、再燃焼の終期の工程が行われる後期交流室Ｙとで構成される。
そして、その構造は、前記再燃焼炉ｂの内部で、前記主燃焼炉ａから導入したガスを十分な時間だけ滞留しつつも、前記主燃焼炉ａに十分な燃焼空気を流通させることによってダイオキシン等の有害物質を完全に燃焼した後に大気中へ排出することを図ったものであって、当該再燃焼炉ｂの内部で複数回の交流を経ることができる構造を採用したものである。 <Reburning furnace>
The re-combustion furnace b is located in the front AC chamber X where the re-combustion initial and middle processes are performed, and the rear AC chamber Y where the re-combustion final process is performed. Composed.
And the structure is such that dioxins are circulated through the main combustion furnace a while allowing the gas introduced from the main combustion furnace a to stay in the recombustion furnace b for a sufficient time. In such a structure, harmful substances such as these are completely burned and then discharged into the atmosphere, and a structure capable of undergoing a plurality of alternating currents inside the reburning furnace b is adopted.

図に示す例の前記再燃焼炉ｂは、例えば、前記主燃焼炉ａに対する前記再燃焼炉ｂの容積比を、例えば、前記主燃焼炉ａから単位時間（例えば１秒）当たりに排出されるガスの量に、前記主燃焼炉ａから流入したガスを前記再燃焼炉ｂ内において完全燃焼できるに足る時間（例えばｔ秒）を乗じた容積を最低限の容積として備え、直方体状の室内の四か所において、４通りの交流（流れながら一定の領域に滞留すること）を経て排出できる構成を採ったものである。   The recombustion furnace b in the example shown in the figure, for example, discharges the volume ratio of the recombustion furnace b to the main combustion furnace a, for example, from the main combustion furnace a per unit time (for example, 1 second). The minimum volume is a volume obtained by multiplying the amount of gas by a time (for example, t seconds) sufficient to allow the gas flowing in from the main combustion furnace a to be completely combusted in the recombustion furnace b. In four places, the structure which can discharge | emit through 4 types of alternating currents (retaining in a fixed area | region while flowing) is taken.

この例は、当該再燃焼炉ｂの前方下位の導入口１に面し、且つバーナー２の火炎又は当該火炎で加熱及び加速されたガスの下位に位置する第一交流部３と、前記バーナー２の火炎又は当該火炎で加熱及び加速されたガスの上位に位置する第二交流部４と、前記第一交流部３の後方にあって、且つ前記バーナー２の火炎又は当該火炎で加熱及び加速されたガスの下位に位置する第三交流部５と、前記第二交流部４及び前記第三交流部５の後方にある前記後期交流室Ｙを備える。   In this example, the first alternating current section 3 that faces the lower front inlet 1 of the reburning furnace b and that is positioned below the flame of the burner 2 or the gas heated and accelerated by the flame, the burner 2 The second alternating current section 4 positioned above the flame of the gas or the gas heated and accelerated by the flame and the rear of the first alternating current section 3 and heated and accelerated by the flame of the burner 2 or the flame A third AC section 5 located below the gas, and the second AC section Y behind the second AC section 4 and the third AC section 5.

この例では、前記第一交流部３と前記第三交流部５との間に、前記第一交流部３から前記第三交流部５へのガス流入を抑制する前仕切壁７を備え、前記第二交流部４及び前記第三交流部５と前記後期交流室Ｙとの間に、前記第二交流部４から前記後期交流室Ｙへのガス流入を回避する後仕切壁８を備える（図７参照）。   In this example, a front partition wall 7 that suppresses gas inflow from the first AC part 3 to the third AC part 5 between the first AC part 3 and the third AC part 5 is provided. Between the second AC part 4 and the third AC part 5 and the late AC room Y, there is provided a rear partition wall 8 for avoiding gas inflow from the second AC part 4 to the late AC room Y (FIG. 7).

前記後仕切壁８は、前記第一交流部３、第二交流部４及び前記第三交流部５からなる前記前期交流室Ｘと前記後期交流室Ｙを仕切る壁であって、前記第二交流部４と前記第三交流部５との境界線上の中央部に前記バーナー２の火炎及び当該火炎によって加熱及び加速されたガスが流通する連絡孔９を備える。
前記バーナー２は、前記後期交流室Ｙの後壁に水平配置され、前記連絡孔９の中央に向けて水平な火炎を放射する。 The rear partition wall 8 is a wall that partitions the early AC room X and the late AC room Y composed of the first AC part 3, the second AC part 4, and the third AC part 5. A communication hole 9 through which the flame of the burner 2 and the gas heated and accelerated by the flame circulates is provided at the center of the boundary line between the part 4 and the third AC part 5.
The burner 2 is horizontally disposed on the rear wall of the late AC room Y and emits a horizontal flame toward the center of the communication hole 9.

前記第一交流部３は、その後方における幅方向中央部に導入口１を備え、当該導入口１より広い底面は、その前部に当該第一交流部３の前方より後方へ下るスロープ１０を備える。
この例の前記後期交流室Ｙは、前記第二交流部４と前記第三交流部５よりも横幅が狭く、前記後仕切壁８の下方で開口する流通孔１１を介して前記後期交流室Ｙと連通し排煙路へ続く排出口１２を上位に有する。 The first AC unit 3 includes an introduction port 1 at the center in the width direction behind the first AC unit 3, and a bottom surface wider than the introduction port 1 has a slope 10 that descends from the front of the first AC unit 3 to the rear of the front unit. Prepare.
The late AC room Y of this example has a narrower width than the second AC part 4 and the third AC part 5, and the late AC room Y through a flow hole 11 that opens below the rear partition wall 8. And a discharge port 12 that leads to the smoke exhaust passage.

上記再燃焼炉ｂの構造により、前記主燃焼炉ａから第一交流部３へ流入したガスは、前方及び左右に広がり、更に上昇気流に乗り、前記バーナー２の火炎及び当該火炎によって加熱及び加速されたガスに接し、又は当該火炎及び当該火炎によって加熱及び加速されたガスの前方又は側方を回り込んで前記第二交流部４へ誘導される。   Due to the structure of the recombustion furnace b, the gas flowing from the main combustion furnace a into the first alternating current section 3 spreads forward and left and right, and further travels ascending current, and is heated and accelerated by the flame of the burner 2 and the flame. The gas is brought into contact with the generated gas, or the gas is heated and accelerated by the flame and circulates in front or side of the gas and is guided to the second AC unit 4.

当該再燃焼炉ｂの前壁に衝突したガスは、当該前壁と前記バーナー２の火炎及び当該火炎によって加熱及び加速されたガスとの衝突点を中心としてその放射方向を経て反転し、各々の反転方向に存在する前記第一交流部３又は前記第二交流部４において交流する。   The gas colliding with the front wall of the reburning furnace b is reversed through the radiation direction around the collision point between the front wall, the flame of the burner 2 and the gas heated and accelerated by the flame, The first AC unit 3 or the second AC unit 4 that exists in the reverse direction exchanges current.

その際、前記第一交流部３においては、当該再燃焼炉ｂのバーナー２の火炎又は当該火炎で加熱及び加速されたガスが、前記主燃焼炉ａに繋がる前記導入口１から流入したガスを巻き込み又は退ける形で交流し、前記第二交流部４においては、前記再燃焼炉ｂのバーナー２の火炎又は当該火炎で加熱及び加速されたガスが、前記第一交流部３を経たガスを巻き込み又は退ける形で交流させる。   In that case, in the said 1st alternating current part 3, the gas heated and accelerated by the flame of the burner 2 of the said recombustion furnace b, or the said flame, the gas which flowed in from the said inlet 1 connected to the said main combustion furnace a is used. In the second AC section 4, the flame of the burner 2 of the recombustion furnace b or the gas heated and accelerated by the flame entrains the gas that has passed through the first AC section 3. Or let them interact with each other.

前記第二交流部４を経て前記火炎又は当該火炎で加熱及び加速されたガスを回り込み、巻き込まれ、又は退けられたガスのうち、前記第三交流部５側に出たガスは、前記火炎又は当該火炎で加速されたガスの方向に添って前記前仕切壁７に衝突し反転することにより交流し、前記火炎又は当該火炎で加速されたガスを回り込んで再び前記第二交流部４において交流する。   Of the gas that has passed through the second AC part 4 and has been entrained, entrained, or withdrawn from the flame or gas heated and accelerated by the flame, the gas that has flowed out to the third AC part 5 side is the flame or Along the direction of the gas accelerated by the flame, it collides with the front partition wall 7 and reverses it, so that the flame or the gas accelerated by the flame wraps around and exchanges again in the second AC section 4. To do.

その際、前記第三交流部５においては、前記再燃焼炉ｂのバーナー２の火炎又は当該火炎で加熱及び加速されたガスが、前記第二交流部４を経たガスを巻き込み又は退ける形で交流し（図７参照。前記バーナー２の出力によっては、図６の様に、交流しない場合もある。）、前記第二交流部４においては、前記再燃焼炉ｂのバーナー２の火炎又は当該火炎で加熱及び加速されたガスが、前記第三交流部５を経たガスを巻き込み又は退ける形で交流させる。   In that case, in the said 3rd alternating current part 5, the flame of the burner 2 of the said recombustion furnace b, or the gas heated and accelerated by the said flame is an alternating current in the form which entrains or retreats the gas which passed through the said 2nd alternating current part 4. (Refer to FIG. 7. Depending on the output of the burner 2, there may be no alternating current as shown in FIG. 6.) In the second alternating current section 4, the flame of the burner 2 of the reburning furnace b or the flame concerned The gas heated and accelerated in step 2 causes the gas that has passed through the third AC portion 5 to be entrained or retreated.

前記第三交流部５での交流から離脱して相対的に狭所である前記後期交流室Ｙへ流入したガスは、加速され且つ上昇気流に乗って上位の排出口１２を介して排煙路へ導かれる。
その際、前記第三交流部５を経たガスは、前記再燃焼炉ｂのバーナー２の火炎又は当該火炎で加熱及び加速されたガスに巻き込まれ又は退けられる形で交流し、その一部は、前記連絡孔９を通じて前記第二交流部４又は前記第三交流部５へ帰還し、再び、第二交流部４又は前記第三交流部５における交流に供される。
それ以外のガスは、前記再燃焼炉ｂのバーナー２の火炎又は当該火炎で加熱及び加速されたガスを回り込んで排煙路に向かうこととなる。 The gas that has left the AC in the third AC section 5 and flows into the later AC room Y, which is relatively narrow, is accelerated and rides on the updraft to the flue gas path via the upper outlet 12. Led to.
At that time, the gas that has passed through the third AC section 5 is exchanged in the form of being caught or retreated by the flame of the burner 2 of the reburning furnace b or the gas heated and accelerated by the flame, and a part thereof, It returns to the said 2nd alternating current part 4 or the said 3rd alternating current part 5 through the said communication hole 9, and is provided to the alternating current in the 2nd alternating current part 4 or the said 3rd alternating current part 5 again.
The other gas goes around the flame of the burner 2 of the reburning furnace b or the gas heated and accelerated by the flame and goes to the flue gas path.

上記再燃焼炉ｂは、前記主燃焼炉ａから流入するガスを、それに含有する煤等を完全燃焼させるに足る時間（例えば１秒以上）滞留させ得る容積を備え、且つ上記構成により、当該再燃焼炉ｂに導入されたガスに対し、前記排煙路に至るまでに、少なくとも、室内の三か所又は四か所において三通り又は四通りの交流を経る期会が与えられ、当該室内における通過位置に応じて循環の一部又は全部が一回又は複数回行われることにより、当該再燃焼炉ｂにおいて十分な滞留時間を確保できる。
尚、この様に、前記再燃焼炉ｂにおいて十分な滞留時間を確保できると言う効果は、前記第三交流部５を積極的に区画しない構成、即ち、前記第一交流部３、第二交流部４、及び前記後期交流室Ｙからなる構成によっても得ることができる。 The re-combustion furnace b has a volume capable of retaining the gas flowing in from the main combustion furnace a for a time (for example, 1 second or more) sufficient to completely burn the soot contained therein, For the gas introduced into the combustion furnace b, at least three or four places in the room are subjected to three or four exchanges before reaching the flue gas passage, A part of or all of the circulation is performed once or a plurality of times according to the passage position, so that a sufficient residence time can be secured in the recombustion furnace b.
In this way, the effect that a sufficient residence time can be ensured in the recombustion furnace b is that the third AC portion 5 is not positively divided, that is, the first AC portion 3 and the second AC portion. It can also be obtained by a configuration comprising the part 4 and the late AC room Y.

＜主燃焼炉＞
前記主燃焼炉ａには、前記特許文献に記載のいずれの主燃焼炉を採用しても良いが、前記特許文献６乃至特許文献８に記載の主燃焼炉の様に、バーナー１３の火炎方向側の天面に排気口６を設けると共に、同方向側の端面に、遺体を搭載する台車を出し入れするための扉（図示省略）を設けた構造の主燃焼炉ａを採用することが望ましい。 <Main combustion furnace>
As the main combustion furnace a, any of the main combustion furnaces described in the above-mentioned patent documents may be adopted, but like the main combustion furnaces described in the above-mentioned patent documents 6 to 8, the flame direction of the burner 13 It is desirable to employ a main combustion furnace a having a structure in which an exhaust port 6 is provided on the top surface on the side, and a door (not shown) is provided on the end surface on the same direction side for loading and unloading the carriage on which the body is mounted.

前記バーナー１３の火炎の伸びが抑制されず広範囲にわたって火炎による直接燃焼が可能となる点で、人手がかからず自動火葬に適している他、火炎によってガスが排気口６に向けて加速されること、及び前記排気口６からガスが引かれることに伴い短縮されかねない前記主燃焼炉ａでの排気の滞留時間は、上記再燃焼炉ｂで確保し得るガスの滞留時間によって十分に補うことができ、それに伴い前記主燃焼炉ａの構造で過度に促進されかねない排気スピードを抑制することができるからである。   The flame of the burner 13 is not suppressed, and direct combustion by a flame is possible over a wide range, and it is suitable for automatic cremation without manpower. In addition, the gas is accelerated toward the exhaust port 6 by the flame. In addition, the residence time of the exhaust gas in the main combustion furnace a, which may be shortened as the gas is drawn from the exhaust port 6, should be sufficiently compensated by the residence time of the gas that can be secured in the recombustion furnace b. This is because the exhaust speed that can be excessively promoted by the structure of the main combustion furnace a can be suppressed.
