Description

[Detailed Description of the Invention] The present invention relates to an oil combustor that gasifies and burns petroleum fuel and radiates heat rays from a red-hot member heated by the combustion flame through a heat-resistant transparent cylinder.

Conventionally, a dual-tube type combustion tube is installed on the fire pan of a top-and-bottom wick type combustor, and the outer tube of the combustion tube is made of a heat-resistant, transparent tube, so that the outer flame that becomes red-hot due to combustion in the wick is heated. Although an oil combustor in which heat rays from a cylinder are radiated through the heat-resistant transparent cylinder is known, the oil combustor with this conventional structure has the following drawbacks.

■ Because petroleum fuel is pumped up and burned with a wick,
Combustion heat amount is approximately 1500Kcal/h ~ 2000Kcal
Suitable for low calorific value of around 2000 / h.
When increasing from 0 Kcal/h to 4000 Kcal/h, the equipment becomes extremely large.

■ Because petroleum fuel is pumped up and burned with a wick,
The combustion width is narrow and room temperature cannot be controlled by switching between low and high calorific values.

■ Because it is difficult to make the outer flame tube, which is the red-hot component, glow well, the efficiency of heat radiation relative to width is low, and the visual heating effect is still poor.

The object of the present invention is to provide an oil combustor that is small in size, can increase the amount of combustion heat, and has a high heating effect by radiation, by solving the deficiencies of the conventional structure described above.

A component 17 is a fuel passage formed in the central axis of the burner body 10 and the burner head 15, and the fuel passage 1
The oil supply pipe 7 is connected to the lower part of the fuel passage 7 by a nut 18, and the upper part of the fuel passage 17 is sealed.

19... is a fuel hole formed in the shaft portion of the burner head 15 and communicating the gas chamber 16' and the fuel passage 17;
Fuel is supplied into the gas chamber 16' through the fuel hole 19.

20... are gas holes formed in the gas chamber component 16 and communicating the gas chamber 16' and the inside of the burner body 10;
Fuel gas is supplied from the gas hole 20 into the burner body 10 and mixed with primary air to form a mixed gas.

21 is a flame port formed between the outer periphery of the burner head 15 and the burner body 10, and mixed gas is ejected from the flame port 21.

22... is a secondary air hole formed on the outside of the burner body 10, 23 is a spark-type or coil-type ignition device that ignites the mixed gas ejected from the flame port 21, and 24 is a burner. It is a heat-resistant transparent cylinder such as glass that is placed on the installation surface of the main body 10 and constitutes a combustion tube, and the mixed gas flows from the flame port 21 and the secondary air flows from the secondary air hole 22 to the transparent cylinder 2.
The cylindrical body 24 ensures the stability of the flame during combustion, allows the combustion state to be checked from the outside, and improves the heating effect.

25 is a support rod that is screwed into the center of the burner head 15 and stands upright; 26 is fixed to the upper surface of the support rod 25, and is fitted to the upper end of the transparent cylinder 24 to prevent the light from transmitting along with the burner body 10. This is a bowl-shaped top plate that supports the cylindrical body 24.

Therefore, the transparent cylinder 24 is clamped and fixed between the burner body 10 and the top plate 26.

Reference numeral 27 denotes a red-hot member made of a heat-resistant wire mesh tube or the like, which is welded to the inner surface of the top plate 26 and suspended within the translucent cylinder 24 at intervals. It is made to become red-hot by the flame of the flame.

Note that the power supply to the gasifier 9 is set to be stopped when the temperature of the burner body 10 becomes high enough to gasify kerosene.

That is, the gasifier 9 is set to be driven only during initial combustion.

Therefore, during combustion in the above embodiment, when the drive switch 29 is turned on and the blower fan 6, electromagnetic pipe 8, and gasifier 9 are energized, the blower fan 6 supplies primary air into the burner body 10. , by the electromagnetic pipe 8,
Kerosene is gasified by the gasifier 9 and sent to the burner body 1

During combustion, the gas chamber parts 16 prevent the burner head 15 and the gas chamber 16' from being cooled by the primary air, and the gasification of the fuel is performed stably.
Since the burner head 15 is connected to the burner head 15, the temperature of the burner head 15 is increased, and the top plate 26 becomes red hot, thereby improving the heating effect.

As described above, according to the present invention, the burner body includes a gasification means for gasifying oil, a flame port for spouting gas fuel,
a heat-resistant, transparent cylinder that is placed on the burner body and forms a combustion tube, located outwardly from the flame port; a top plate that holds a heat-resistant transparent cylinder together with the main body; a combustion gas discharge port formed in the top plate; and a combustion gas discharge port fixed to the inner surface of the top plate, spaced apart from the heat-resistant transparent cylinder, and above the flame port. Since it is provided with a red-hot member hanging down at the position, the following effects are produced.

■ Oil is gasified and combusted at the flame port of the burner body, so combustion is complete and the calorific value is approximately 2000Kcal.
Even if it is as large as ~4000 Kcal, the device does not become large and can be made into a compact device.

■ Since petroleum is gasified and combusted at the flame port of the burner body, the combustion range is wide and indoor temperature can be controlled well, allowing comfortable heating to be performed according to the size of the room in which it is installed.

■ The combustion flame can be directly viewed through the heat-resistant translucent cylinder, making it easy to check the combustion status and constantly monitoring whether combustion is normal or not. Since the radiation is radiated through the cylinder, the heating effect can be improved depending on the width and visibility.

■ The heat-resistant transparent cylinder placed on the burner body is held by the burner body and a top plate with a combustion gas discharge port, so the heat-resistant transparent cylinder does not wobble when transporting the equipment. can prevent damage.

(2) Since the red-hot member is suspended from the top plate at a position above the flame opening with a distance from the heat-resistant transparent cylinder, the red-hot member is exposed to the combustion flame and high-temperature combustion gas, and the degree of redness can be improved.

(2) Since the top plate holds the heat-resistant light-transmitting tube and the red-hot member, the number of parts is reduced, and the positional relationship between the red-hot member, the heat-resistant light-transmitting tube, and the flame port can be determined relatively accurately.
