Abstract

PURPOSE:To make it possible to allow a stable vaporizing combustion flame to rise up by sufficiently mixing a vapor gas within a vaporizing cylinder with combustion air, and allowing the thus obtained air mixed gas to flow uniformly into a gas chamber under a reduced pressure condition, and ejecting to burn the gas uniformly through a large number of gas ejection holes. CONSTITUTION:A combustion plate 102 provided with a large number of gas ejection holes 103 is laid within a combustion cylinder 101 to form a gas chamber 104. A vaporizing cylinder 106 whose base end opening side communicates with a gas chamber is rotatably provided on the central opening part 105 of the gas chamber. Further, a gas pressure equalizing plate 107 is disposed within the gas chamber so that an annular and narrow gas flow passage 108 is formed between the free end side and the combustion cylinder, thereby partitioning the interior of the gas chamber. An inside speed reducing ring 110 and an outside speed reducing ring 111 are disposed at a suitable interval between the combustion plate and the gas pressure equalizing plate so that an annular air mixed gas outlet port 109 the supply side of which is connected to the gas flow passage 108 and the ejection side of which is connected to the gas chamber, is formed therebetween. As a result, a stable vaporizing combustion flame can be allowed to rise up.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention involves thoroughly stirring and mixing the vaporized gas generated in the vaporizing cylinder with combustion air to form a complete mixed gas, and then reducing the pressure of the mixed gas. The present invention relates to a vaporizing burner that can uniformly flow gas into a gas chamber under the same conditions and perform fume combustion at an even jet speed from a large number of gas nozzle holes.

Conventional technology Conventionally, no matter how large the area of the combustion disk installed in the combustion tube, there was no vaporization burner that burns the super-oxidized mixed gas all at once through the combustion disk in a state of equal pressure even though it was circulated through the combustion disk before this application was filed. For example, this is publicly known as described in Publication of Utility Model Publication No. 52-54036, and this will be explained using FIG. 3. That is, a combustion plate 2 having a large number of gas ejection holes 8 is installed in a combustion tube 1 to form a gas chamber 3 therein, and a central open part 5 of the gas chamber 3 has one side open. The vaporizing tube 4 is rotatably positioned to provide communication between the vaporizing tube 4 and the gas chamber 3, and the gas chamber 3 is provided with an annular gas passage 7 having an appropriate number of mixed gas passages 7 at its peripheral end. The inside of the gas chamber 3 is partitioned by diagonally disposing a pressure equalizing plate 6.

Problems to be Solved by the Invention By the way, in the above-mentioned known vaporizing burner, when the mixed gas generated in the vaporizing cylinder is caused to flow into the gas chamber from the mixed gas passage along the gas pressure equalizing plate, Since the gas velocity of the mixed gas is fastest at the position where it passes through the mixed gas passage, the mixed gas that has passed through the mixed gas passage and entered the gas chamber is sent to the gas jet provided directly above the mixed gas passage. In contrast, the air-fuel mixture ejects from the gas nozzle located further away from the air-fuel mixture passageway, that is, closer to the vaporizer cylinder, has a slower ejection speed, resulting in combustion. The vaporization tube exhibits an uneven combustion state in which flames are formed in close contact with the disk surface, and the resulting mixed gas cannot be combusted all at once with an even jet velocity from the many gas nozzles. Since the vaporized gas generated within the combustion chamber has a short distance to reach the gas chamber, the agitation and mixing with the combustion air is incomplete, resulting in problems such as the inability to achieve complete superacidity in the mixed gas.

Means for Solving the Problems The present invention solves the above-mentioned problems, and the details thereof will be explained below with reference to FIGS. 1 and 2, which correspond to embodiments.

That is, in the first invention, a combustion plate LL12 having a large number of gas ejection holes 103 is installed inside the combustion tube 101. A gas chamber 104 is formed between the combustion tube 101 and the combustion disk 102. A vaporizing cylinder 106 whose proximal open side communicates with the gas chamber 104 is rotatably located in the central open portion 105 of the gas chamber 104 . In the gas chamber 104 formed as described above, a gas pressure equalizing plate 107 is arranged so that a narrow annular gas flow passage 108 is formed between the free end side and the combustion tube 1u1. 104 partition the inside.

An inner speed reducer is formed between the combustion plate 102 and the gas pressure equalizing plate 107 so that an annular mixed gas flow port 109 is formed, which connects the supply side to the gas flow passage 10B and the ejection side to the gas chamber 104. ring 110 and outer deceleration ring 111
In the second aspect of the invention, in the first aspect having the above configuration, the gas pressure equalizing plate 107 has an inner surface of the inner deceleration ring 110. A large number of blowholes 123 are bored through which part of the mixed gas is blown.

Operation Now, when the burner is started, the carburetor 106 rotates at high speed and combustion air is blown into the carburetor 1GB, and after passing through the carburetor 106, it is delivered to the gas pressure equalizing plate 107. The combustion air flows outward along the gas flow path 108, and while increasing the flow velocity, collides with the outer deceleration ring 111 to be decelerated and depressurized.At the same time, the combustion air collides with the inner deceleration ring 110, and is decelerated and depressurized. Finally, after flowing into the gas chamber 104 under an equal pressure condition through the gas flow port 112, it is injected into the combustion tube 101 through the many gas ejection holes 103 at an even ejection speed.

Therefore, if fuel is supplied to the vaporization cylinder 106 under the above conditions, the fuel will be diffused and atomized within the vaporization 1:1106,
Furthermore, the particles are further atomized by the injection action of the blown combustion air, and the combustion tube 1
01 and is ignited for main combustion. Then, the entire vaporization cylinder 106 is heated by the raw combustion flame generated, so that the fuel supplied into the vaporization cylinder 106 is evaporated and mixed with the combustion air to form a high-pressure mixed gas. The gas flows from the vaporizing cylinder 106 along the pressure equalizing plate 107, increases the flow velocity through the narrow gas flow path 108, and blows forcefully against the inner surface of the outer deceleration ring 111 to decelerate the gas.
The gas flows into the regas chamber 104 through the gas flow port 109 while being depressurized. A part of the mixed gas decelerated and depressurized by the collision with the one-sided deceleration ring 111 is transferred to the mixed gas flow port 10.
Since the mixture gas flows toward the inner deceleration ring 110 without passing through B and hits the inner deceleration ring 110, the flow rate of the mixed gas is further reduced, and at the same time, the pressure is reduced, and then the mixture gas flows from the gas flow port 109. The gas flows into the gas chamber 104.

Therefore, the vaporized gas is transferred from the vaporization tube 106 to the gas chamber 104.
How many times during the circulation of the gas (stirring and mixing is performed, and as it is mixed with the combustion air, a completely mixed gas is formed). Since the flow velocity is also reduced and the pressure is not reduced at the same time, the air-fuel mixture flows into the gas chamber 104 from the gas flow port 109 under an equal pressure state, and finally from the many gas jet holes 103 under a uniform jet speed. The gas is emitted to form a vaporized combustion flame of a certain length on the combustion plate 102.

In addition, in the vaporizing burner of the second invention, as shown in FIG. After blowing against the outer deceleration ring 111 and the inner deceleration ring 110 to decelerate and reduce the pressure, the mixed gas distribution port 10
At the same time, the other mixed gas flows into the gas chamber 104 with an even pressure from 9, and at the same time, on the way to the gas flow passage 108, the other mixed gas flows through the numerous fumarole holes 123 bored in the gas pressure equalizing plate 101. After blowing against the inner surface of the inner deceleration ring 110 to decelerate, reduce pressure, and stir and mix to form a homogeneous mixed gas, the mixed gas flows through the mixed gas distribution port 109 under an equal pressure state.
The gas flows into the gas chamber 104.

Therefore, in the gas chamber 104, the mixture gas of equal pressure, which has been decelerated and depressurized by the inner deceleration ring 110 and the outer deceleration ring 111, flows into the gas chamber 104 and is stored, so that a vaporized combustion flame of a constant length is always generated. The field soil can be kept stable.
