JPS5896908A - Thin evaporation type oil burner - Google Patents

Abstract

PURPOSE:To enable a sufficient evaporizing combustion even if the height of an entire burner unit is made thin by a method wherein the combustion oil is atomized into a combustion cylinder through each of the splashing parts arranged at a plate-like evaporizing inner cylinder and an injection gas branch cylinder which is integrally rotated at an outer circumference of the inner cylinder. CONSTITUTION:Upon combustion, at first, a plate-like evaporizing inner cylinder 5 and a humidifying outer cylinder 6 are rotated at a high speed through a rotary shaft 4, and at the same time, the combustion air is blown from the air passage 3 to mixture gas passage 11 and injection passage 10, and then oil is sent from an oil feeding pipe 22 to an oil defuser 20. The oil is moved in the plate-like evaporizing inner cylinder 5 and injected to a branch wall 13 in an injection gas separating cylinder 12 during its rotation from splashing end 19. The oil is injected into a combustion cylinder 1 through a splashing part 15 and ignited through a spark plug 23. When a temperature in the humidifying gas passage 11 rises due to combustion flame, the combustion oil in the plate-like evaporizing inner cylinder 5 is evaporated and gasified during its flow, and then the gasified oil is mixed with the combustion air and injected from main injection flame passage 17, and finally injected from sub-injection flame passage 18.

Description

[Detailed Description of the Invention] The present invention enables good vaporization combustion to be maintained over a long period of time by quickly transitioning fuel from a raw combustion state to a vaporization combustion state even when the overall height of the burner is made as thin as possible. The present invention relates to a thin vaporizer that can be continued.

First, the present applicant carried out live combustion in the combustion cylinder by the rotating centrifugal action of the vaporization cylinder and the replenishment action of combustion air, and then the raw AM flame generated. After the inside of the vaporization cylinder is heated to the vaporization atmosphere temperature, the fuel is quickly evaporated and vaporized, the generated vaporized gas is mixed with combustion air, and a complete mixture of gases is created and injected to achieve good vaporization combustion. We have developed a vaporizing bath that can be used continuously for a long period of time.

However, in conventional vaporizing burners of this type, the vaporizing cylinder that rotates within the combustion cylinder is formed into a conical shape with a long body wall in order to atomize the fuel and promote the generation of vaporized gas. be.

Therefore, in order to carry out the above-mentioned vaporization combustion, the height of the vaporization cylinder itself inevitably becomes taller, and as a result, the height of the entire burner also becomes taller, resulting in a heating device with a shorter combustion chamber. This results in the inconvenience of not being able to use it as a heating source.
This is why the appearance of a short vaporizing burner was strongly desired.

In view of the above, the present invention includes a combustion cylinder K having an open tip and a ventilation passage provided on the base bottom wall, a dish-shaped vaporizing inner cylinder having an open tip and a closed base end, which are rotatably disposed, Outside 41 of the concave vaporizing inner cylinder
The AK has its tip open, an air supply window that communicates with the proximal side pressure ventilation passage, and a moisture chamber that is attached to the bottom wall of the PflA cylinder so that it rotates concentrically with the dish-shaped vaporizing cylinder or does not rotate. A cylinder is disposed between the dish-shaped inner vaporizer cylinder and the air mixture outer cylinder to form an air mixture passage whose tip is open and whose proximal end communicates with the ventilation passage. On the outer periphery of the tip, there is a branch wall on the proximal end side that bisects the open end side of the mixed gas passage, and the tip 11111K has a guide wall extending toward the surface of the dish-shaped vaporizing inner cylinder, and the branch wall and the guide wall are provided on the tip end. Fumarous gas branch tubes with fuel splashing parts installed halfway between them and the wall are installed integrally at intervals,
For example, the open end side of the mixed gas passage is branched into a main combustion path that spews smoke toward the front end of the combustion cylinder, and a sub-smoking path that jets flame toward the surface of the dish-shaped inner cylinder. Even if the fuel is burnt raw or the carburetor tube that generates the mixed gas is made extremely thin, the fuel will automatically shift from the raw burner state to the vaporizer combustion state in the same manner as with conventional vaporizer burners. The present invention is intended to provide a wide-shaped vaporizing burner that can at least continue good vaporizing combustion over a long period of time. Let's discuss an example.

In FIGS. 1 and 2, reference numeral 1 denotes a short combustion tube with an open tip and a ventilation passage 3 provided approximately in the middle of the proximal bottom wall 2; 3, a rotating shaft 4 is inserted into the rotating shaft 4, and a dish-shaped vaporizing inner cylinder 5 with an open tip and a closed base end is directly connected to the distal end side of the rotating shaft 4 so as to be rotatable. On the outside of the inner cylinder 5, the peripheral edge is curved toward the open side of the combustion cylinder 1 so as to wrap around the outer periphery of the dish-shaped vaporizer inner cylinder 5. Connect the moisture outer cylinder 6 with the air supply window T that communicates with the connecting tool 8.
Alternatively, the air mixture outer cylinder 6 may be integrally connected to the dish-shaped inner vaporizer cylinder 5 through the inner cylinder 5 so as to rotate concentrically, or the outer cylinder 6 may be connected to the bottom wall 2 of the combustion cylinder 1 without being integrally connected to the dish-shaped inner cylinder 5. The air-fuel mixture outer cylinder 6 is placed in a non-rotatable state by being attached to the cylinder via the connecting member 9. A blowhole passage 10 is formed between the bottom wall 2 of the cylinder 1 and the air-fuel mixture outer cylinder 6, the base end of which is connected to the ventilation passage 3, and the distal end thereof open into the combustion cylinder 1.

Reference numeral 11 denotes a hot gas passage formed between the dish-shaped inner vaporizing cylinder 5 and the air mixture outer cylinder 6, which is open at the tip and communicates with the ventilation path 3 from the proximal end.

It is a fume gas branching cylinder which is equipped with a guide wall 14 extending toward the surface of the dish-shaped vaporizing inner cylinder 5, and furthermore, a window-shaped fuel scattering part 15 is provided in the middle between the branching wall 13 and the guide 4 and 14. By installing the branch tube 12, the open end side of the hot gas passage 11 is directed toward the front end side of the combustion tube 1, and the main flame path 17 that generates flame is directed toward the surface of the dish-shaped inner cylinder 5. It is made to branch into a sub-flame path 18 which is bursting with flames.

Note that the open end of the dish-shaped L-tube 5 is connected to the mixed gas branch tube 12.
It is formed at a fuel scattering end 19 that sprays fuel toward.

Reference numeral 20 denotes a hollow inverted conical fuel oil cylinder integrally attached to the central inner surface of the proximal end of the dish-shaped inner vaporizer cylinder 5 so as to form an appropriate melt oil outflow gap 21 between it and the surface of the dish-shaped inner vaporizer cylinder 5. The fuel oil diffuser 20 is a diffuser, and the tip of the oil pipe 22 is visible from the inner surface of the fuel oil diffuser 20 . 23 is a spark plug. As shown in FIG. 3, the fuel oil diffuser 20 is constructed by recessing the central part of the dish-shaped vaporizing inner cylinder into an inverted circular concave shape, so that the fuel diffuser 207 is attached to the dish-shaped vaporizing cylinder 5.
It may be formed integrally at the center of the fuel oil diffuser 2q so that the tip of the oil feed pipe 22' can be seen on the surface of the fuel oil diffuser 2q.

Reference numeral 6' indicates a moisture outer cylinder disposed outside the dish-shaped vaporizing cylinder 5', and 11' indicates a moisture gas communication path formed between the dish-shaped inner vaporizing cylinder q and the air mixture outer cylinder 6'.

The one shown in FIG. 4 has a dish-shaped vaporizer inner cylinder 5 which extends slightly toward the distal end side than the dish-shaped vaporizer inner cylinder 5 shown in FIG. This is another example of a thin vaporizing burner that can achieve continuous maintenance of vaporizing combustion even when the burner is formed so as to become deep.
In the case of if+1, the dish-shaped vaporizing inner cylinder 5'', the air mixture outer cylinder C, and the fume gas branching cylinder 1z are connected by a plurality of connecting rods 2.
4, which are integrally connected to each other by a wall plate 25, and are branched into a main blowing passage 17' and a sub-smoking passage 18', which are on the open end side of the mixed gas passage 11'. It branches into a branching cutting path 26 and a sub-branching cutting path 27, and the vaporized flame emitted from the sub-branching cutting path 21 is transferred to the dish-shaped vaporizing inner cylinder 5'.
At the same time, the vaporization combustion field from the main branch cutting passage 26 is cut in the center direction so as to cover the vaporization melt φ flame of the sagi to vaporize it. This is to promote the generation of gas, and in this embodiment, a fuel scattering section 2B is opened and provided in the middle of the dish-shaped vaporizing inner cylinder, and the fuel is transferred from the fuel scattering section 28 to the fumarole gas. Branch tube 1
In the direction 2', it is dispersed in fine particles.

Next, the operation of the present invention will be explained.

Now, in FIGS. 1 and 2, the rotating shaft 4 causes the dish-shaped vaporizing inner cylinder 5 and the air mixture outer cylinder 6 to rotate at high speed, and at the same time, the air for am is transferred from the four air passages 3 to the air mixture passage 11 and the injection cylinder. Air is blown into the passage 10, and then fuel is sent to the fuel diffuser 20 from the oil delivery pipe 22.

Then, the fuel is transferred from the fuel diffuser 20 to the dish-shaped vaporizing inner cylinder 5.
The fuel is transferred from the furnace front scattering end 19 to the branch arm 13 of the rotating fume gas branch pipe 12, and the sprayed fuel further passes through the fuel scattering section 15 and becomes fine particles. It is sprayed into the one-φ cylinder 1, ignited by the spark plug 23,
The raw smoke is generated, and the temperature inside the mixed gas passage 11 is quickly raised to the vaporizing atmosphere temperature by the generated raw smoke and flames.

After the temperature inside the hot gas passage 11 is raised to the vaporizing atmosphere temperature in this way, the fuel supplied to the inner surface of the dish-shaped vaporizing inner cylinder 5 is
Due to the heating effect, it evaporates and becomes vaporized gas during the transition, and the generated vaporized gas is stirred and mixed with the furnace air to become a completely warm gas, which is then sent from the main combustion path 17 to the tip of the combustion tube 1. At the same time as being eaten by the side! ! l] Guidance from Funenro Kuikiri Ia
The surface of the dish-shaped vaporizing inner cylinder 5 is cut along the direction 14. As a result, even if the vaporizer inner cylinder 5 is thin and dish-shaped, it can be heated by the vaporization-slash-burning cutting from the sub-cutting passage 18, and the temperature inside the humid gas passage 11 can be raised to the vaporizing atmosphere temperature. Mixed gas is generated continuously, and it is not possible to continue good vaporization and combustion for a long time without interrupting it. It can be crushed.

In short, the present invention has the above-described structure, but even if the vaporizing inner cylinder 5 is formed into a dish-like shape, the fuel oil can be transferred to the dish-shaped vaporizing inner cylinder 5 and the fume that rotates integrally on its outer periphery. The raw fuel is sprayed into the bonito phosphorus cube 1 in fine particles through the fuel oil scattering end 19 and the fuel oil scattering part 15 provided in the gas branch tube 12, so that the raw fuel is completely formed, and the moisture gas passage 11 is quickly circulated. After that, the temperature is raised to the vaporizing atmosphere temperature, and thereafter the fuel sent thereon is turned into a completely hot gas, while the main flame path 17 is cut off toward the arrow end side of the combustion tube 1, and the fuel is vaporized as a heating source. At the same time, a part of the mixed gas is cut off from the sub-cutting passage 18 along the guide wall 14 toward the surface of the dish-shaped vaporizing inner cylinder 5.
is intensely heated, and the generation of humid gas inside the hot gas passage 11 is not interrupted in any way and continuously.
Is it fuel? Not only can it automatically shift from the phosphorous state to the vaporization combustion state, but the overall height of the vaporization burner has been made extremely low, allowing it to be easily inserted even in low-rise burners for efficient heating work. It produces effects that can be achieved with certainty.
