In addition, observation windows 34 and 35 are formed in the horizontal portion of the gas storage chamber 22.
The exhaust chamber 3 is connected to the secondary combustion chamber outlet 26 via an exhaust cylinder 36, and the combustion gas burned in the combustion chamber 21 passes through the exhaust duct 4 and is forcibly exhausted by the exhaust fan 5.

つぎに、本実施例による燃焼装置の燃焼方法について説明する。以下の説明においては、臭気ガスとして有機廃棄物を熟成醗酵させる際に発生するアンモニアを例に説明する。
まず、バルブ２９を閉じ、バルブ３２、３３を開いた状態で、一次燃焼室１の底部１２に設けられた燃料供給口１５から燃料となる廃油を供給する。底部１２には燃焼される廃油が溜まり、底部１２は燃焼皿の働きをする。つぎに、点検口１４から点火用燃焼物を廃油の溜まっている底部１２の上に供給し、送風ファンにより空気供給管１６から空気を送り込むと、垂直空気噴出管１８および水平空気噴出管１９から一次燃焼室１に空気が送り込まれて燃焼を開始する。一方、底部１２の近傍では、空気噴出孔１９Ａから空気が回転を生じるように供給され、廃油は気化しつつ燃焼し、燃焼が盛んになるにつれて燃焼温度が上昇し、空気噴出孔１９Ａから供給される空気によって燃焼ガスと空気の攪拌が促進される。
このとき、排気ファン５を回転させることによって一次燃焼室１、二次燃焼室２および排気室３内の燃焼ガスは吸引されるため、一次燃焼室１内の燃焼ガスは一次燃焼室１内を上昇し、渦状に回転する流れとなり、空気と燃焼ガスとの混合が促進されるとともに、空気噴出孔１８Ａから供給される新たな空気によって更に燃焼が促進される。 Next, a combustion method of the combustion apparatus according to the present embodiment will be described. In the following description, ammonia generated when aging fermentation of organic waste as odor gas will be described as an example.
First, in a state where the valve 29 is closed and the valves 32 and 33 are opened, waste oil as fuel is supplied from the fuel supply port 15 provided in the bottom 12 of the primary combustion chamber 1. Waste oil to be burned accumulates in the bottom portion 12, and the bottom portion 12 functions as a combustion dish. Next, when the combustion product for ignition is supplied from the inspection port 14 onto the bottom 12 where the waste oil is accumulated, and the air is sent from the air supply pipe 16 by the blower fan, the vertical air jet pipe 18 and the horizontal air jet pipe 19 Air is sent into the primary combustion chamber 1 to start combustion. On the other hand, in the vicinity of the bottom portion 12, air is supplied from the air ejection holes 19 </ b> A so as to rotate, and the waste oil is combusted while being vaporized. The combustion temperature rises as the combustion increases, and is supplied from the air ejection holes 19 </ b> A. The stirring of the combustion gas and air is promoted by the air.
At this time, the combustion gas in the primary combustion chamber 1, the secondary combustion chamber 2, and the exhaust chamber 3 is sucked by rotating the exhaust fan 5, so that the combustion gas in the primary combustion chamber 1 passes through the primary combustion chamber 1. Ascending and rotating in a spiral shape, the mixing of air and combustion gas is promoted, and combustion is further promoted by new air supplied from the air ejection holes 18A.

一次燃焼室１の上部に至った燃焼ガスは、一次燃焼室出口部１７から二次燃焼室入口部２０を通って二次燃焼室２の燃焼室２１に導入される。二次燃焼室２内に導入された燃焼ガスは、燃焼流規制板２５によって渦状に回転する流れとなって二次燃焼室出口部２６に移動する。このとき、空気供給ダクト３０、３１からガス収納室２２に導入された空気がガス供給孔２７２から燃焼室２１内に導入され、燃焼ガスは渦状に回転する流れによって、燃焼ガスと空気の攪拌が更に促進され、燃焼が盛んになり、燃焼温度は１５００度以上に上昇して完全燃焼する。
燃焼室２１内で燃焼した燃焼ガスは、排気ファン５により二次燃焼室出口部２６から排気室３に導かれ、排気室３内を熱を奪われながら上昇して燃焼温度を低下させつつ排気ダクト４から外部に放出される。このとき、燃焼は完全燃焼しているので、廃油は完全分解されて、ダイオキシン、ＳＯｘなどの公害物質の含有量が数１０分の１〜数百分の１と非常に小さいきれいな排気が得られる。ＮＯｘはダイオキシンやＳＯｘよりも減少割合は小さいものの、数分の１に減少する。 Combustion gas reaching the upper portion of the primary combustion chamber 1 is introduced from the primary combustion chamber outlet portion 17 into the combustion chamber 21 of the secondary combustion chamber 2 through the secondary combustion chamber inlet portion 20. The combustion gas introduced into the secondary combustion chamber 2 moves to the secondary combustion chamber outlet portion 26 as a flow rotating in a spiral shape by the combustion flow regulating plate 25. At this time, the air introduced into the gas storage chamber 22 from the air supply ducts 30 and 31 is introduced into the combustion chamber 21 through the gas supply holes 272, and the combustion gas and the air are stirred by the flow rotating in a spiral shape. Further, the combustion is promoted and the combustion temperature rises to 1500 ° C. or more to complete combustion.
The combustion gas burned in the combustion chamber 21 is led from the secondary combustion chamber outlet 26 to the exhaust chamber 3 by the exhaust fan 5 and rises while taking heat away from the exhaust chamber 3 to reduce the combustion temperature. It is discharged from the duct 4 to the outside. At this time, since the combustion is complete combustion, the waste oil is completely decomposed, and a clean exhaust with a content of pollutants such as dioxin and SOx as small as several tenths to one hundredths is obtained. . Although NOx is smaller than dioxin and SOx, it decreases to a fraction.

こうして一次燃焼室１および二次燃焼室２内における燃焼が高温で安定した状態になったとき、バルブ２９を開き、バルブ３２、３３を閉じると、臭気ガスダクト２８からガス収納室２２に導入されたアンモニアガスがガス供給孔２７２から燃焼室２１内に導入される。導入されたアンモニアガスは一次燃焼室１からの燃焼ガスとともに渦状に回転する流れになって攪拌されながら高温で燃焼する。アンモニアは高温で燃焼されると水とＮＯｘに分解されるが、ＮＯｘはさらに供給されるアンモニアとともに燃焼されると、４ＮＨ３+４ＮＯ＋Ｏ２→４Ｎ２＋６Ｈ２Ｏで表わされる化学反応により窒素ガスと水に分解されるので、完全に無臭化、無毒化される。 Thus, when the combustion in the primary combustion chamber 1 and the secondary combustion chamber 2 became stable at a high temperature, when the valve 29 was opened and the valves 32 and 33 were closed, the odor gas duct 28 was introduced into the gas storage chamber 22. Ammonia gas is introduced into the combustion chamber 21 from the gas supply hole 272. The introduced ammonia gas combusts at a high temperature while being stirred in a flow rotating in a spiral with the combustion gas from the primary combustion chamber 1. Ammonia is decomposed into water and NOx when burned at a high temperature. However, when NOx is further burned together with the supplied ammonia, nitrogen gas and nitrogen gas are decomposed by a chemical reaction represented by 4NH 3 + 4NO + O 2 → 4N 2 + 6H 2 O. Since it is decomposed into water, it is completely non-brominated and detoxified.

このように、二次燃焼室２内にアンモニアを導入して燃焼させることによりアンモニアは無臭化、無毒化されて、窒素ガスと水が排気ダクト４から外部に放出される。同時に、一次燃焼室１内で廃油を燃焼したときに生じるＮＯｘも二次燃焼室２内でアンモニアとともに燃焼させることにより窒素ガスと水に分解することができる。したがって、本実施例による燃焼装置は、ＮＯｘの発生量を数１０分の１〜数百分の１に大きく低減させることができる。
本実施例による燃焼装置は、底部１２に溜めた液体燃料を気化して燃焼する一次燃焼室１と、一次燃焼室１に連設された二次燃焼室２とを有する燃焼装置であり、一次燃焼室１を、縦型の燃焼壁１１と、液体燃料を溜める底部１２と、燃焼壁１１の上部で二次燃焼室２に連設される一次燃焼室出口部１７と、一次燃焼室１のほぼ中心に配置される垂直空気噴出管１８とから構成し、二次燃焼室２を、横型の燃焼室２１と、一次燃焼室出口部１７に連設して一次燃焼室１で燃焼した燃焼ガスを取り入れる二次燃焼室入口部２４と、二次燃焼室２の内部に設けられた燃焼流規制板２５と、燃焼ガスの取り出し口である二次燃焼室出口部２６とから構成し、二次燃焼室入口部２４を燃焼室２１の一端側端面に、二次燃焼室出口部２６を燃焼室２１の他端側端面にそれぞれ接続し、燃焼流を排気ダクト４外へ導く排気ファン５を二次燃焼室２の下流側に設け、複数の空気噴出孔１９Ａを水平空気噴出管１９に設け、燃焼流規制板２５を螺旋形状とし、一次燃焼室１では空気噴出孔１８Ａ、１９Ａによって燃焼ガスを渦状に回転させて上昇させ、二次燃焼室２では一次燃焼室１の上部に至った燃焼ガスを二次燃焼室２の一端側端部から他端側端部の方向に、螺旋形状の燃焼流規制板２５によって回転させて移動させるものである。
このように本実施例による燃焼装置は、一次燃焼室１を縦型の燃焼壁１１、二次燃焼室２を横型の燃焼室２１で構成し、一次燃焼室１では空気噴出孔１９によって燃焼ガスを渦状に回転させて上昇させ、二次燃焼室２では一次燃焼室１の上部に至った燃焼ガスを二次燃焼室２の一端側端部から他端側端部の方向に移動させることで、一次燃焼室１を上昇した燃焼ガスは、水平方向に流れ方向を変えて、二次燃焼室２の一端側端部から他端側端部に向かって流れ、また、二次燃焼室２では、螺旋形状の燃焼流規制板２５によって渦状に回転する燃焼流を発生させることで、渦状に回転する流れとなる。更に、燃焼流を排気ダクト４外へ導く排気ファン５を二次燃焼室２の下流側に設けることで、燃焼ガスを強制的に水平方向に向かわせることができる。
また、本実施例による燃焼装置は、底部１２に溜めた液体燃料を気化して燃焼する一次燃焼室１と、一次燃焼室１に連設された二次燃焼室２とを有する燃焼装置であり、一次燃焼室１を、縦型の燃焼壁１１と、液体燃料を溜める底部１２と、燃焼壁１１の上部で二次燃焼室２に連設される一次燃焼室出口部１７と、一次燃焼室１のほぼ中心に配置される垂直空気噴出管１８とから構成し、二次燃焼室２を、横型の燃焼室２１と、一次燃焼室出口部１７に連設して一次燃焼室１で燃焼した燃焼ガスを取り入れる二次燃焼室入口部２４と、二次燃焼室２の内部に設けられた燃焼流規制板２５と、燃焼ガスの取り出し口である二次燃焼室出口部２６とから構成し、二次燃焼室入口部２４を燃焼室２１の一端側端面に、二次燃焼室出口部２６を燃焼室２１の他端側端面にそれぞれ接続し、燃焼流を排気ダクト４外へ導く排気ファン５を二次燃焼室２の下流側に設け、複数の空気噴出孔１９Ａを水平空気噴出管１９に設け、燃焼流規制板２５を複数の板から構成し、一次燃焼室１では空気噴出孔１９Ａによって燃焼ガスを渦状に回転させて上昇させ、二次燃焼室２では一次燃焼室１の上部に至った燃焼ガスを二次燃焼室２の一端側端部から他端側端部の方向に、燃焼流規制板２５によって流れ方向を屈折させて移動させるものである。
本実施例の燃焼装置によれば、一次燃焼室１の底部で気化した燃焼ガスは、一次燃焼室１の内部で渦状に回転するため、燃焼ガスと空気が攪拌される。従って、一次燃焼室１での燃焼は完全燃焼に近づく。そして一次燃焼を終えた燃焼ガスは二次燃焼室２へ移動する。この二次燃焼室２に移行した燃焼ガスは、二次燃焼室の内部において更に渦状の回転によって、燃焼ガスと空気とは攪拌されるため更に完全燃焼に近づかせることができる。
そして本実施例による燃焼装置は、二次燃焼室２に空気を導入する開閉自在の空気供給ダクト（空気導入口）３０、３１と、臭気ガスを導入する開閉自在の臭気ガスダクト（ガス導入口）２８を設け、まず空気供給ダクト（空気導入口）３０、３１から二次燃焼室に空気を導入することで、二次燃焼室２において燃焼温度が１５００度以上の高温に上昇して完全燃焼する。その後、臭気ガスダクト（ガス導入口）２８を開き、空気供給ダクト（空気導入口）３０、３１を閉じると、二次燃焼室２に臭気ガスが導入され、臭気ガスは高温で燃焼されるので、臭気ガスに起因する臭気を除去するとともに、空気汚染や人体へ悪影響を引き起こす臭気ガスを無臭化、無毒化することができる。
また本実施例による燃焼装置における二次燃焼室２は、燃焼室２１と、燃焼室２１の外部を覆うガス収納室２２を有しており、燃焼室２１は一次燃焼室１で燃焼した燃焼ガスを取り入れる二次燃焼室入口部２４と、燃焼室２１の内部に設けられた燃焼流規制板２５と、燃焼した燃焼ガスを取り出す二次燃焼室出口部２６で構成され、二次燃焼室入口部２４の周辺部にはガス収納室２２に連通する開口２７が設けられており、空気供給ダクト（空気導入口）３０、３１と臭気ガスダクト（ガス導入口）２８はガス収納室２２に連通している。上記構成によれば、二次燃焼室２に空気および臭気ガスを選択的に導入可能であり、空気を導入しているときは燃焼ガスと空気とが攪拌されて高温で完全燃焼させることができ、二次燃焼室に臭気ガスを導入しているときは燃焼ガスと臭気ガスとが攪拌されて、臭気ガスを高温で燃焼させることができる。
また本実施例による燃焼装置に導入する臭気ガスとして、家畜の糞尿や生ゴミ等の有機廃棄物を堆肥化する堆肥化施設やし尿処理施設などで発生するアンモニアガスとすることで、アンモニアガスを窒素と水に熱分解して無臭、無毒化することができる。また、廃油などを燃焼して発生するＮＯｘを分解することができるので、排気中の公害成分を飛躍的に減少させることができる。
以上の説明においては、臭気ガスとしてアンモニアを例に説明したが、硫化水素などの臭気ガスも同様に無臭化、無毒化することができる。 Thus, ammonia is made non-bromide and non-toxic by introducing ammonia into the secondary combustion chamber 2 and burning it, and nitrogen gas and water are discharged from the exhaust duct 4 to the outside.
