Description

[Detailed explanation of the idea] The present invention relates to a vaporizing oil combustor.

The applicant of the present application previously proposed a vaporizing oil combustor that includes a pot burner for ignition, a vaporizer, and a burner for burning vaporized gas that burns vaporized gas vaporized by the vaporizer.

This product is supplied with oil into the vaporization cylinder through the oil supply pipe.

Then, when the vaporization cylinder is not heated, the oil flows into the pot burner through the oil supply pipe connecting the vaporization cylinder and the pot burner, and is ignited and burned within the pot burner.

Then, when the vaporization cylinder is heated by combustion by the pot burner, the supplied oil is immediately evaporated in the vaporization cylinder, and is sent into the vaporization gas combustion burner by air from the blower, where it is automatically vaporized and combusted by the vaporization gas combustion burner. to move to.

However, combustion using a pot burner only needs to have enough heat to evaporate the oil supplied into the vaporization cylinder.

On the other hand, combustion in a vaporized gas combustion burner requires a relatively large amount of refueling, and as mentioned above, when the refueling amount is directly supplied to the carburetor and flows into the pot burner, the refueling becomes excessive and incomplete. This has the disadvantage of causing combustion.

The object of the present invention is to obtain a vaporizing oil combustor that does not have the above disadvantages. a vaporizer tube 4 provided in a position communicating with the gas chamber 3 of the burner 2 and exposed to the air of the burner 2; a blower 5 for ventilating the pot burner 1 and the vaporized gas combustion burner 2; 4, and an oil supply pipe 7 that connects the vaporizing cylinder 4 and the pot burner 1, a branch passage 8 is provided to recirculate a part of the oil to the oil supply pipe 7. Let me be intimidating.

The illustrated pot burner 1 has a rectangular shape, and a rectangular vaporized gas combustion burner 2 is provided at the upper end of the upper flange 1a. 3, a duct 9 connected to the blower 5 faces the remaining one side, and the vaporizing cylinder 4 having a circular cross section is interposed between the duct 9 and the gas chamber 3 facing the duct 9.

The vaporizing cylinder 4 was installed so as to descend from the side connected to the duct 9, so that the oil supplied from the oil supply pipe 6 flowed down to the duct 9 side.

Reference numeral 10 denotes a circumferential annular groove 11 provided at the connecting end of the vaporization cylinder 4, which is a stabilizer provided in the vaporization cylinder 4 to give swirl to the air blowing; 12, a baffle provided within the vaporization cylinder 4;
3 is a flame port provided on the inner surface of the burner 2 for burning vaporized gas; 14;
1 is an air hole provided in the pot burner 1, 15 is an electromagnetic pump connected to the oil supply pipe 6, 16 is an ignition heater provided in the pot burner 1, and 17 is a wire mesh provided on the inner surface of the vaporizing cylinder 4.

When all the ignition heaters 16 are energized and the electromagnetic pump 15 is operated to supply oil from the oil supply pipe 6, the oil flows through the vaporization cylinder 4, and a portion of it flows into the pot burner 1 via the oil supply pipe 7. The fuel flows in and is ignited and burned by the ignition heater 5.

Note that the other part returns to the oil tank or leveler via the branch path 8.

When all of the oil is evaporated (several seconds after ignition), the oil supply to the pot burner 1 is cut off and combustion shifts to complete combustion using the vaporization burner.

Incidentally, a regulating valve 18 may be interposed in the branch passage 8 as shown in FIG. 3 if necessary.

In this way, according to the present invention, the oil supply pipe 7 that connects the vaporizing cylinder 4 and the pot burner 1 is provided with a branch passage 8 through which part of the oil is returned, so that the amount of oil supplied to the pot burner 7 can be reduced. Not only can incomplete combustion by the pot burner 7 be prevented, but also sufficient oil can be supplied to the vaporized gas combustion burner 2 during vaporization combustion.
