本発明は、＝対の氷室の間に燃焼室を囲んで多数の水管
を配備しボイラ（水管式、貫流式など）に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a boiler (water tube type, once-through type, etc.) in which a large number of water tubes are arranged between a pair of ice chambers and surrounding a combustion chamber.
従来のこの種のボイラの例を第１図及び第２図に示せば
、環状の上部水室１及び下部水室２との間に水管３，４
が二重の円筒状をなして配列され、中央に燃焼室５を形
成し、第２図の如き配置にて煙道人口６、煙道１が形成
され、ケーシング８との間に煙道９を形成し煙道１０に
至る。An example of a conventional boiler of this kind is shown in FIGS. 1 and 2. Water pipes 3 and 4 are connected between an annular upper water chamber 1 and a lower water chamber 2.
are arranged in a double cylindrical shape, forming a combustion chamber 5 in the center, a flue population 6 and a flue 1 are formed in the arrangement as shown in FIG. and reaches the flue 10.
１１はバーナである。11 is a burner.
水管３又は４は隣接するものは互いに密着して第２図の
如く連続してらせん形の壁を形成する。Adjacent water pipes 3 or 4 are in close contact with each other to form a continuous spiral wall as shown in FIG.
水管３又は４の上下端は直径が細（形成されて上部氷室
１又は下部水室２と接続しているので隣接する小直径部
との間に隙間を生ずる。The upper and lower ends of the water pipe 3 or 4 have a narrow diameter (formed) and are connected to the upper ice chamber 1 or the lower water chamber 2, so that a gap is created between the adjacent small diameter portions.
この隙間はキャスター１２で埋められて水管で形成され
る前述のらせん状の壁はその両側の空間を遮断する。This gap is filled with casters 12, and the aforementioned spiral wall formed by the water pipe blocks off the space on both sides.
１３は熱応力を避けるためのたわみ部、１４は炉底のキ
ャスターである。13 is a bending part to avoid thermal stress, and 14 is a caster at the bottom of the hearth.
このボイラの運転に当たっては、中央のバーナ１１を燃
焼せしめれば輻射及び燃焼ガスの対流により燃焼室５に
面している水管３の内側が加熱され、煙道人口６より煙
道１を通過する燃焼ガスにより煙道ｌの両面の水管３，
４が加熱され、最外部の煙道９を通過する間に水管４が
加熱される。When operating this boiler, when the central burner 11 is fired, the inside of the water pipe 3 facing the combustion chamber 5 is heated by radiation and convection of the combustion gas, and the gas passes through the flue 1 from the flue population 6. The combustion gas causes water pipes 3 on both sides of the flue l,
4 is heated, and the water pipe 4 is heated while passing through the outermost flue 9.
この際比較的高温の内側の水管３が昇水管となり、比較
的低温の外側の水管４が降水管となり、水が循環する。At this time, the relatively high-temperature inner water pipe 3 serves as a rising pipe, and the relatively low-temperature outer water pipe 4 serves as a downcomer pipe, so that water circulates.
このようなボイラをさらに有効に稼動せしめるために一
層の効率及び能力の向上が望まれている。In order to operate such boilers more effectively, further improvements in efficiency and capacity are desired.
効率及び能力向上のためには種々の方式があるが、その
一つとしては燃焼量を多くして燃焼ガスの速度を犬にし
て熱貫流率を増加する方法、又は限定されたボイラの容
積内に有効な伝熱面を極力多（設ける方法などがある。There are various ways to improve efficiency and capacity, one of which is to increase the amount of combustion to reduce the velocity of combustion gas and increase the heat transfer coefficient, or to increase the heat transfer coefficient within the limited boiler volume. There are methods to provide as many effective heat transfer surfaces as possible.
しかし前者の方法では通気抵抗は速度の二乗に比例し、
かつ風量は燃焼量に比例するので、給気装置（例えば押
込送風機）の動力は燃焼量の三乗に比例する。However, in the former method, the ventilation resistance is proportional to the square of the velocity,
Moreover, since the air volume is proportional to the combustion amount, the power of the air supply device (for example, a forced air blower) is proportional to the cube of the combustion amount.
このことは設備動力の増加のみならず、給気装置の吐出
圧が高（なり騒音の原因になる。This not only increases the power of the equipment, but also causes the discharge pressure of the air supply system to become high (which causes noise).
また、第２図の構造の代りに煙道人口６から先の煙道が
左右に分かれ１８０度通過した反対側で合流し、外側に
流れ再び左右に分かれ１８０度通過した反対側（即ち煙
道人口６のある側）で再び合流して外へ導かれる方式が
ある。In addition, instead of the structure shown in Figure 2, the flue starting from flue population 6 is divided into left and right sides, passes through 180 degrees, merges on the opposite side, and flows outward again, dividing into left and right sides and passes through 180 degrees on the opposite side (i.e., the flue passes through 180 degrees). There is a method in which they rejoin on the side with a population of 6) and are led outside.
この方式では中間部の流速を低下せしめることはできる
が、バーナ１１から出た燃料油の粒子が、バーナ１１の
付近の流路１５（第１図）においては、完全燃焼せずに
大きな粒子のまま煙道ｌに入る。Although this method can reduce the flow velocity in the intermediate section, the fuel oil particles coming out of the burner 11 are not completely combusted in the flow path 15 (Fig. 1) near the burner 11, and are formed into large particles. Enter the flue.
燃焼室５の下部近くの流路１６から煙道人口６に入るも
のは完全燃焼するから差支えないが、上記の不完全燃焼
粒子を含んだガスが煙道ｌに入ると冷却されるので未燃
のまま排出さればい塵量が増大する。There is no problem if the gas that enters the flue 6 from the flow path 16 near the bottom of the combustion chamber 5 is completely combusted, but if the gas containing the incomplete combustion particles mentioned above enters the flue 1, it will be cooled and will not be burned. If it is discharged as is, the amount of dust will increase.
これを防ぐにはバーナ１１付近のミキシングを良好にし
て燃焼室５内における燃焼を完全にする必要がある。To prevent this, it is necessary to improve the mixing near the burner 11 to ensure complete combustion within the combustion chamber 5.
このミキシングによりばい塵量を低減することができる
。This mixing can reduce the amount of dust.
しかしその反面ミキシングのための送風機動力を要し、
またミキシングが激しければそれだけＮＯｘ発生量が増
大して公害の原因となる。However, on the other hand, it requires blower power for mixing,
Moreover, the more intense the mixing, the more the amount of NOx generated increases, causing pollution.
本発明は、燃焼室を水管にて形成した燃焼室壁にて囲み

である。The present invention is different from the conventional one by surrounding the combustion chamber with a combustion chamber wall formed of water pipes, providing a smoke pipe within the water pipe, and providing a smoke vent in a part of the wall of the combustion chamber near the inlet of the smoke pipe. In order to eliminate the above drawbacks, the combustion gas path from the combustion chamber is doubled, one entering the flue and the other entering the smoke vent, to reduce the flow velocity, reduce ventilation resistance, and reduce power and noise. At the same time, the water in the water tube is heated from the inner and outer surfaces to increase the heating area than the surface area of the water tube. The object of the present invention is to provide a boiler that can suppress the generation of dust and NOx.

This boiler is characterized by:
本発明を実施例につき図面を用いて説明すれば、第３図
、第４図、第５図において、水管３，４は同心円的に密
に並べられて内側は燃焼室壁１１、外側は煙道壁１８が
形成される。To explain the present invention with reference to the drawings according to embodiments, in FIGS. 3, 4, and 5, water pipes 3 and 4 are closely arranged in a concentric circle, with the combustion chamber wall 11 on the inside and the smoke pipe on the outside. A road wall 18 is formed.
各水管３，４は隣接するものは互いに密着し、（部分的

は煙道ｌと煙道９とを通ずるために水管３，４のうち１
本あるいは２本を除いて形成した通路（第２図煙道人口
６の如き）はない。Adjacent water pipes 3 and 4 are in close contact with each other (partially welded in some cases), and in order to communicate between the combustion chamber 5 and the flue 11 or between the flue l and the flue 9, the water pipes 3 and 4 are 1 of them
There are no passages (such as flue population 6 in Figure 2) formed except for a book or two.
水管３の中には煙管１９が設けられ、その流入口２０は
バーナ１１の反対側である下端に近（、燃焼室５に面し
て開口し、流出口２１は流入口２０と反対側の端部近く
に煙道７に而して設けられる。A smoke pipe 19 is provided in the water pipe 3, and its inlet 20 is open facing the combustion chamber 5 (close to the lower end opposite to the burner 11), and the outlet 21 is located on the opposite side to the inlet 20. A flue 7 is provided near the end.
水管３の下端は直径が細（絞られ（又は細いパイプが接
続されて）下部水室２に接続されるが、第５図に示す如
（隣接するものの間に隙間が通煙口２２として残されて
いる。The lower end of the water pipe 3 is connected to the lower water chamber 2 by having a narrow diameter (or by connecting a thin pipe), but as shown in FIG. has been done.
通常はこの隙間は水管４の下端に示す如（キャスターで
埋められているが、本実施例においては上端は埋められ
ているが下端は特に通煙口として開放されたままにしで
ある。Normally, this gap is filled with casters as shown at the lower end of the water pipe 4, but in this embodiment, the upper end is filled, but the lower end is left open especially as a smoke vent.
水管４の中には煙管２３が設けられ、その流入口２４は
流出口２１と同じ側の端部付近に煙道Ｉに面して開口し
、流出口２５は流入口２４と反対側の端部付近に煙道９
に而して開口している。A smoke pipe 23 is provided in the water pipe 4, and its inlet 24 opens facing the flue I near the end on the same side as the outlet 21, and the outlet 25 opens at the end opposite to the inlet 24. Flue 9 near the part
It is open.
水管４の上、下端はキャスター１２にて埋められ密閉さ
れてそる。The upper and lower ends of the water pipe 4 are buried and sealed with casters 12 and warped.
上記通煙口と煙管１９の流入口２０とは水管３の一方の
、同じ側の端部に設けられているので、通煙口を通るガ
ス流と、煙管１９を通るガス流とが並列に形成されるよ
うになっている。Since the smoke port and the inlet 20 of the smoke pipe 19 are provided at one end of the water pipe 3 on the same side, the gas flow passing through the smoke port and the gas flow passing through the smoke pipe 19 are parallel to each other. It is beginning to form.

て上端にて流出口２１よりの燃焼ガスと合流し、流入口
２４より煙管２３に入り、水管４の水を内部より加熱し
て流出口２５より煙道９に入り、水管４の外方の面を加
熱しながら煙道１０に至り排出される。During operation, when the central burner 11 is fired, the inner side of the water pipe 3 is heated by radiant and convection heat, and the combustion gas is divided into an inlet 20 and a smoke vent 22 at the bottom, and one enters the smoke pipe. 19, the water in the water pipe 3 is heated from the inside and enters the upper end of the flue l through the outlet 21, and the other water rises through the flue l to the outer surface of the water pipe 3 and the inner surface of the water pipe 4. The water in the water tube 4 is heated from the inside, enters the flue 9 through the outlet 25, and enters the flue 23 through the inlet 24. It reaches the flue 10 and is discharged while heating the outer surface.
本実施例は上記の如（構成され、作用するので燃焼ガス
は高温の状態で並列の流れとして二重され煙管１９及び
煙道ｌを流れる。The present embodiment is constructed and operates as described above, so that the combustion gases flow through the flue 19 and the flue 1 in dual parallel flows at high temperatures.
通気抵抗△Ｐは△ｐｃｘ＝ｙＸγ
Ｖ：流速
γ：密度
であり速度が支配的であり、単に流路の一部を二重した
だけでも△Ｐの低下に効果があるが、さらに密度ｒ即ち
体積Ｖも関係し、その体積Ｖはの如く絶対温度に比例す
るので、高温の状態で分流させて速度を落すことが全体
の通気抵抗を小さくする効果が一層大である。Ventilation resistance △P is △pcx = y The volume V is also related, and since the volume V is proportional to the absolute temperature, dividing the flow in a high temperature state to reduce the speed has a greater effect on reducing the overall ventilation resistance.
しかして分流状態で冷却されて体積が小になったガスが
再び合流し、煙管２３を通過するが、煙管２３は煙管１
９よりも本数を多くとることができ、かつ燃焼ガスの体
積も小となっているので流速も小となり通気抵抗が小さ
い。The gases, which have been cooled in the divided state and whose volume has become smaller, join together again and pass through the smoke pipe 23, but the smoke pipe 23 is connected to the smoke pipe 1.
Since the number can be larger than that of 9 and the volume of combustion gas is small, the flow velocity is also small and the ventilation resistance is small.
しかして伝熱面積は、水管３，４の中の煙管１１９．２
３の面積が増加し℃いるので単位面積当たりの伝熱量が
少なく熱効率は向上する。Therefore, the heat transfer area is the smoke pipe 119.2 in the water pipes 3 and 4.
Since the area of 3 increases in temperature, the amount of heat transferred per unit area is reduced and the thermal efficiency is improved.
その上燃焼室５からの燃焼ガスの出口はバーナ１１の反

ミキシングを行なう必要もな（、ばい塵の抑制が行なえ
ると共にＮＯｘの発生な抑制することもできる。Furthermore, the outlet of the combustion gas from the combustion chamber 5 is located on the opposite side of the burner 11, and the structure allows only the combustion gas to flow out after complete combustion, so there is no need for particularly intensive mixing for complete combustion. (In addition to suppressing dust, it is also possible to suppress the generation of NOx.
水管３がフィンを有し、隣接するフィンが接続されて燃
焼室壁１７が形成される場合には水管３の端部は絞られ
ていないので、フィンの一部を切欠いて通煙口２２を形
成することができる。When the water pipe 3 has fins and adjacent fins are connected to form the combustion chamber wall 17, the end of the water pipe 3 is not constricted, so a part of the fin is cut out to form the smoke vent 22. can be formed.
煙管１９は必らずしも水管３全部に設ける必要はない。The smoke pipe 19 does not necessarily need to be provided in all the water pipes 3.
煙管２３は必らずしも水管４全部に設ける必要はな（、
この場合、比較的受熱量が小さくなっている外側の水管
のうち、この煙管２３を備えない水管４が加熱量が小さ
いので一層水の比重が高（なり降水を促進し、水の循環
を円滑にしてボイラ容量を増大せしめることができる。It is not necessary to provide smoke pipes 23 to all water pipes 4 (,
In this case, among the outer water pipes that receive a relatively small amount of heat, the water pipe 4 that is not equipped with the smoke pipe 23 receives a small amount of heat, so the specific gravity of the water is even higher (which promotes precipitation and smoothes water circulation). This allows the boiler capacity to be increased.
燃焼室壁１１０通煙口２２は必らずしも全ての水管３の
間になくともよい。The combustion chamber wall 110 and the smoke vents 22 do not necessarily have to be provided between all the water pipes 3.
煙道壁１８には必要に応Ｃて通煙口２２を設けてもよい
。A smoke vent 22 may be provided in the flue wall 18 if necessary.
煙道壁１８−通煙口２２を設ける場合は、燃焼室壁１１
に通煙口２２を設けた場合と同様に、煙道７及び煙管１
９を通過して合流した全燃焼ガス量が、煙管２３のみな
らず煙道壁１８０８０通煙２にも再び分割されて流れる
ので、燃焼ガスの流速が小となり通気抵抗が小さく、後
半の流れに対しても同様な効果をもたらす。Flue wall 18 - When providing a smoke vent 22, the combustion chamber wall 11
As in the case where the smoke vent 22 is provided in the flue 7 and the smoke pipe 1.
Since the total amount of combustion gas that has passed through 9 and merged is divided again and flows not only to the flue pipe 23 but also to the flue wall 18080 and the smoke passage 2, the flow velocity of the combustion gas is small, the ventilation resistance is small, and the latter half of the flow is It also has the same effect.
煙道壁１８における通煙口２２の位置は、第３図の場合
には水管４の上端付近となし、燃焼室壁１７におけると
同様、キャスターを埋めずに隣接する水管４の上端の隙
間を残して通煙口２２とするか、水管４がフィンを有す
るならフィンの一部を切欠いて通煙口２２を形成しても
よい。The position of the smoke vent 22 in the flue wall 18 is near the upper end of the water pipe 4 in the case of FIG. The smoke vent 22 may be formed by leaving it as the smoke vent 22 or by cutting out a part of the fin if the water pipe 4 has fins.
この場合煙道１０は水管４の片方の端に寄せずにほぼそ
の中央部に設置するのがよい。In this case, it is preferable that the flue 10 is installed approximately in the center of the water pipe 4, without being placed near one end of the water pipe 4.
以上の如き構造においては、通煙口２２の大きさ、配置
、数、煙管１９，２３の大さ、その稼動本数（煙管が多
過ぎる場合は一部を閉塞するなど）などを調整して使用
条件に最も適した状態を選択することができる。In the above structure, the size, arrangement, and number of the smoke vent 22, the size of the smoke pipes 19 and 23, and the number of operating pipes (if there are too many smoke pipes, block some of them, etc.) are adjusted before use. You can choose the state that best suits your conditions.
第６図は別の実ｍ例を示し、いわゆる戻り燃焼を行なわ
しめる場合の例を示す。FIG. 6 shows another example in which so-called return combustion is performed.
即ち、バーナ１１は戻り燃焼用のロングフレーム式のも
のが、やや下に下げて装着され、燃焼ガスは一度底部に
達し℃から反転して燃焼室の周囲に沿って上昇するもの
である。That is, the burner 11 is of a long frame type for return combustion and is mounted slightly lower, and the combustion gas once reaches the bottom, reverses its temperature from °C, and rises along the periphery of the combustion chamber.
戻り燃焼によってさらに完全燃焼とＮＯＸ低減が期待で
きる。Further complete combustion and NOx reduction can be expected through return combustion.
この場合通煙口２２、流入口２０，２４、流出口２１．
２５、煙道１０の位置は第３図の場合と上下が逆となっ
た配置になる。In this case, the smoke vent 22, the inlet 20, 24, the outlet 21.
25. The position of the flue 10 is upside down from that shown in Fig. 3.
上記の実施例は、垂直型の水管式のボイラの例が示され
ているが、質流式のものにも適用でき、また水平式のも
のに対しても適用して同様な効果をもたらすことができ
る。In the above embodiment, an example of a vertical water tube type boiler is shown, but it can also be applied to a quality flow type boiler, and it can also be applied to a horizontal type to produce the same effect. I can do it.
水平式の場合は水平より僅か傾けることが好ましい。In the case of a horizontal type, it is preferable to tilt it slightly from horizontal.
なお、上述の例で、上部水室１及び下部水室２の形状は
円環状のほか、楕円状、正方形状、長方形状などの環状
であっても上述の効果に変りはない。In addition, in the above-mentioned example, the above-mentioned effect does not change even if the shape of the upper water chamber 1 and the lower water chamber 2 is annular, such as an ellipse, a square, or a rectangle, in addition to the annular shape.
本発明により、ボイラ全体の寸法を太き（することなく

る効果を有するものである。According to the present invention, the transmission area is increased to be larger than the surface area of the water bottle without increasing the overall dimensions of the boiler, increasing the thermal efficiency, and the combustion gas flow path is doubled as a parallel flow in a high temperature state to reduce the speed. By significantly reducing ventilation resistance, equipment power is reduced, discharge pressure is low (noise is also reduced,
Furthermore, complete combustion is performed to suppress soot and dust, and NO
It is possible to provide a boiler that can prevent pollution by suppressing the generation of x, and has an extremely effective effect in terms of practical and pollution prevention.
