Abstract

PURPOSE:To improve stabilization of combustion, extinguishability and prevention of a foul odor, by a method wherein the inside and the outside of a pot is connected by an air pipe with each other, an oil supply duct is opened in the air pipe, and a part of the air pipe between the opening and the pot is formed in a downward slope facing toward the pot. CONSTITUTION:Combustion air is flowed in a pot 4 through an air pipe 7, petroleum to be controlled by an oil quantity adjuster 12 is flowed in the air pipe 7 from an oil supply duct 8, which is coexisted with combustion air in the air pipe 7 up to the pot 4 and is flowed in the pot 4. Then, the air pipe 7 is heated by heat of the inside of the pot 4 and evaporation of petroleum is expedited. Mixture of air with the evaporated petroleum, therefore, is expedited and combustion is stabilized. At the time of extinguishing, rapid extinction can be performed and safety is improved as there is no adherence of petroleum on the bottom of the inside of the pot 4 and the petroleum is burnt out in a moment.

Compared to a hole oil burner, it eliminates the bad odor when extinguishing a fire and extinguishes the fire quickly.

従来ポット式石油燃焼器はポット内に直接石油を供給し
て石油の気化及び燃焼空気との混合。Conventional pot-type oil combustors supply oil directly into the pot to vaporize the oil and mix it with combustion air.

緒にポット内で行なわれるから燃焼状態は不安定要素を
含んでおり、特に石油の気化部分がポット底面で変動す
ることは望ましいことではなかった。It was designed to burn a mixed gas. And these-
Since the combustion takes place inside the pot, the combustion conditions include unstable factors, and it is particularly undesirable for the vaporized portion of the oil to fluctuate at the bottom of the pot.

また消火直後は石油が油滴または湿り状態で底面に残っ
ており、消火時間も長く消火操作には悪臭をともなうも
のであった。Immediately after extinguishing the fire, petroleum remained on the bottom in the form of oil droplets or in a wet state, and the time it took to extinguish the fire was long, and the extinguishing operation was accompanied by a foul odor.

る。This invention is intended to improve the above problems,
A pot 4 is attached to the air passage 3 connected to the 0PLi port 2 of the blower 1, and a large number of small holes 5 made in the side wall of the pot 4 are opened in the air passage 3, and a combustion chamber 6 is formed above the pot 14. In the combustor, an air pipe 7 is provided to communicate between the outside of the pot 4 and the inside of the pot 4, and an oil pipe 8 is opened in the air pipe 7, and an air pipe 7 is connected to the oil pipe 8 and flows down the air pipe 7 toward the pot 4. It is a pot 2 oil combustor with a slope, and the other end of the air differential connected to pot 4 can be left open, connected to the upper part of the combustion chamber 6 where the draft has weakened, or connected to the air path. Air is supplied to the pot 4 from the air pipe 7. Reference numeral 9 indicates a combustion plate located within the pot 4, and reference numeral 10 indicates a Nukelton installed within the combustion chamber 6, which receives combustion heat, becomes red hot, and radiates heat rays to the outside. 11 is a solenoid valve attached to the oil feed pipe 8, and 12 is an oil amount regulator. Reference numeral 13 designates an electromagnetic pump in place of the oil level regulator, which in combination with the oil level regulator 14 controls the fuel flow rate.

而して流量調節した石油をポット４内に供給し１図示せ
ざる点火装置によって点火すると。Then, the oil whose flow rate is adjusted is supplied into the pot 4 and ignited by an ignition device (not shown).

石油の燃焼時に発生した燃焼ガスは軽くなってポット４
及び燃焼室６を上昇し、ポット４内を負圧力にしている
。この為ポット４にあけた小孔５から燃焼空気が負圧力
のポット４内に流入して石油に供給され燃焼が継続する
。また送風機ｌはポット４外方の風路３の圧力を高める
ように作用して燃焼空気がポット４内に流入しやすくし
ている。The combustion gas generated during the combustion of oil becomes lighter and reaches pot 4.
The combustion chamber 6 is raised to create a negative pressure inside the pot 4. For this reason, combustion air flows into the pot 4 under negative pressure through a small hole 5 made in the pot 4 and is supplied to the oil, thereby continuing combustion. Further, the blower 1 acts to increase the pressure in the air passage 3 outside the pot 4, thereby making it easier for combustion air to flow into the pot 4.

ところでこの発明はポット４内と連絡するエアパイプ７
を取付けたから、小孔５と同様エアパイプ７を介して燃
焼空気がポット４に流入する。そして油量調節器１２等
で流量調節された石油は送油管８を経てエアパイプ７に
送られるから送油管８との接続部からポット４に至るエ
アパイプ７には□、燃焼空気と石油が共存状態で流れる
ようになった。By the way, this invention is based on the air pipe 7 that communicates with the inside of the pot 4.
Since this is installed, combustion air flows into the pot 4 through the air pipe 7 as well as the small hole 5. Then, the oil whose flow rate is adjusted by the oil flow regulator 12 etc. is sent to the air pipe 7 via the oil pipe 8, so in the air pipe 7 from the connection with the oil pipe 8 to the pot 4, combustion air and oil coexist. It started to flow.

一方燃焼が継続してポット４が充分加熱するとポット４

ガスは気化した石油の体積増加も烏って高流速でポット
４内に吹き出されるから、エアパイプ７との接続部に滞
留することなく細かい油滴となってポット４底而全体に
広がり気化してしまうものである。On the other hand, if the combustion continues and pot 4 is sufficiently heated, pot 4
The air pipe 7 connected to the pot 4 becomes hotter the closer it gets to the pot 4, and the vaporization of the oil in the air pipe 7 is accelerated, and since the pipe is thin, the vaporized oil and the air flowing into the pot 4 mix instantly, It became something that was blown into 4. In addition, the oil that could not be vaporized in the air pipe 7 has already been sufficiently preheated in the air pipe 7, and the mixed gas of air and oil flowing into the pot 4 from the air pipe 7 increases the volume of the vaporized oil. Since the oil is blown out into the pot 4 at a flow rate, the oil does not stay in the connection part with the air pipe 7, but becomes fine oil droplets, spreads over the entire bottom of the pot 4, and vaporizes.

従って流量の少い時の石油はほとんどがエアパイプ７内
で気化しかつ空気との混合ガスとなってポット４内に供
給され、流量の多い時に石油の一部が液体のままポット
４に供給されても底面全体で瞬時に気化するから、気化
状態の不安定さはなくなり、かつ大部分の石油がエアパ
イプ７内で予混合を行うから空気と混合が不完全な状態
で燃焼が行なわれることがなくなり。Therefore, when the flow rate is low, most of the oil vaporizes in the air pipe 7 and becomes a mixed gas with air and is supplied into the pot 4, and when the flow rate is high, some of the oil is supplied to the pot 4 as a liquid. However, since the oil vaporizes instantaneously over the entire bottom surface, there is no instability in the vaporization state, and since most of the oil is premixed in the air pipe 7, combustion can occur even though it is incompletely mixed with air. Gone.

優れた燃焼状態を得ることができだ。It is possible to obtain excellent combustion conditions.

うになり安全性が格段に向上したものである。Further, in this invention, since the oil pipe 8 is not directly connected to the pot 4 but to the air pipe 7, the oil pipe 8 is only indirectly heated by the heat of the air pipe 7 and does not reach a high temperature. Therefore, even if oil is present at the tip of the oil pipe 8, if the flow of oil is stopped during fire extinguishing operations, this oil will hardly vaporize, and the very small amount of oil that vaporizes will be diluted by the air flowing inside the air pipe 7. combustion cannot continue. In addition, there is no oil that adheres to the bottom of the borate 4, and the oil 9 spreads over the entire bottom in the form of fine oil droplets, so combustion is completed almost instantly. Therefore, the combustion flame inside the pot 4 can be extinguished within a few seconds after the extinguishing operation, and safety is greatly improved.

為の送風機が兼用できて便利である。In order to promote the vaporization of oil in the air pipe 7, the end of the air pipe 7 may be connected to the combustion chamber 6 so that high-temperature combustion gas is blown into the pot 4, and the flow rate passing through the air pipe differential is To obtain the pot 4 like the upper part of the combustion chamber 6
It is preferable that the location be such that there is a large pressure difference between the inside and outside of the air. If the end of 7 is opened, it can be conveniently used as a blower for forced air.
