従来燃料管を用いて燃料をバーナへ供給する石
油燃焼器では、燃料管は電磁弁などの燃料停止手
段を取付け、消火操作時に燃料停止手段によつて
バーナへ供給する燃料を停止するものである。
Conventionally, in oil combustors that use fuel pipes to supply fuel to burners, the fuel pipes are equipped with fuel stop means such as solenoid valves, and the fuel stop means stops the supply of fuel to the burners during extinguishing operations. .
この時燃料停止手段の取付位置として、高温度
になるバーナ近傍に取付けることは耐熱性が要求
されてむつかしく、バーナから離れた位置に燃料
停止手段を取付けることが一般的である。 At this time, it is difficult to mount the fuel stop means near the burner where the temperature is high because heat resistance is required, and it is common to mount the fuel stop means at a position away from the burner.
バーナから離れた位置に燃料停止手段を取付け

ンク７に吸引するものである。 That is, it is equipped with a burner 1 that burns petroleum fuel, a fuel pipe 2 connected to the burner 1, a fuel pump 3 attached to the fuel pipe 2, and an air passage 4 that supplies combustion air to the burner 1, and an air passage 4 that supplies combustion air to the burner 1. In an oil combustor having a blower fan 5 for supplying air, a fuel stop means 6 is attached to the fuel pipe 2, and an airtight tank 7 attached near the burner 1 and heated by the burner 1 is provided. A connecting pipe 8 is attached to the fuel pipe 2 between the fuel pipe 1 and the fuel stop means 6, and the end of the connecting pipe 8 is communicated with the airtight tank 7. After the fuel supply is stopped by the fuel stop means 6, the fuel in the fuel pipe 2 is and gas is sucked into the airtight tank 7.

容できない空気がバーナ１へ押出される。 In this invention, an airtight tank 7 is installed at a position heated by the burner 1, and the airtight tank 7 is communicated with the fuel pipe 2 through a connecting pipe 8. For this reason,
When the airtight tank 7 is heated by combustion in the burner 1, the density of the air in the airtight tank 7 becomes thinner and the amount of air that can be accommodated decreases.
It flows out to the burner 1 via the fuel pipe 2. By the way, 0
The air stored in the airtight tank 7 at a temperature of 273° C. expands to double its volume, and the air that cannot be stored in the airtight tank 7 is pushed out to the burner 1.

パイプ８に吸引するので、燃料管２に残つた燃料
はバーナ１へ流れず、該バーナ１はすみやかに消
火するものである。 When the fuel stop means 6 stops the fuel by extinguishing the fire, the burner 1 rapidly weakens its firepower and the temperature of the airtight tank 7 drops. For this reason, the airtight tank 7 recovers the amount of air it accommodates and sucks the fuel in the fuel pipe 2 into the connecting pipe 8, so the fuel remaining in the fuel pipe 2 does not flow to the burner 1, and the burner 1 is quickly removed. It is meant to extinguish a fire.

引を継続することができるものである。 In addition, the airtight tank 7 radiates heat, recovers the amount of air it can accommodate, and continues sucking air, so the burner 1
The fuel adhering to the inner walls of the fuel pipe 2 and the connecting pipe 8 is vaporized and mixed with the air coming in from the tank, and the mixture flows into the airtight tank 7. Then, as the temperature of the airtight tank 7 decreases, the vaporized fuel gas condenses in the airtight tank 7 and the amount of suction increases, making it possible to continue suctioning the vaporized gas for a long period of time.
従つて燃料停止手段６によつて消火操作後はバ
ーナ１へ燃料は流れず、すみやかに消火し、消火
後にバーナ１へ燃料が供給される現象は防止でき
た。 Therefore, the fuel stopper 6 prevents fuel from flowing to the burner 1 after the extinguishing operation, and the fire is quickly extinguished, making it possible to prevent fuel from being supplied to the burner 1 after extinguishing the fire.

されるものである。 7 is an airtight tank installed near burner 1, 8
is a connecting pipe installed between the burner 1 and the fuel stop means 6, and the end of the connecting pipe 8 communicates with the airtight tank 7. Therefore, the airtight tank 7, which is heated by the combustion heat of the burner 1, is in communication with the fuel pipe 2, and when heated, the air expands and the condensed fuel is vaporized, passing through the fuel pipe 2 to the burner 1. On the other hand, when the fire is extinguished, the fuel in the fuel pipe 2 and the burner 1
The gas inside is sucked into the connecting pipe 8 and the airtight tank 7.

なつた。 In addition, most of the causes of bad odor generated from the combustor after extinguishing are caused by the decomposition of fuel gas when it comes into contact with the high temperature part of burner 1, but in this invention, even after extinguishing, fuel gas continues to be emitted from burner 1. By preventing the fuel from flowing into the air, we are now able to provide a very sanitary combustor with almost no foul odor after the fire is extinguished.
