Abstract

PURPOSE:To enable a fast transformation of fuel oil from oil combustion state to vaporization combustion state even in a vertical gas chamber by a method wherein the extremity end of the vertical vaporization cylinder having its base end operating as an air blow-in port is connected to the vertical gas chamber for injecting the combustion flame at both sides of the vaporization cylinder. CONSTITUTION:Upon combustion, the combustion air is fed from an air blow-in port 2 into a vertical vaporization cylinder 1 and at the same time fuel oil is injected from an atomizing nozzle 10 into the vertical vaporization cylinder 1, thereafter the mixture is ignited and burned through a spark plug 11. Oil combustion occurs in the vaporization cylinder 1, the oil combustion flame is advanced into a vertical gas chamber 4, thereafter the flame is injected from each of the injection holes 7, 8 of a plurality of combustion parts 5, 6 in a direction toward the vaporization cylinder 1 and its opposite direction, then the vaporization cylinder 1 is heated at its inner and outer sides. Then, the oil combustion is interrupted, the fuel oil is injected again from said nozzle 10 into the vaporization cylinder 1, resulting in that the fuel oil is rapidly evaporated and gasified to show a mixing with the combustion air. The mixture passes through the gas chamber 4 and is injected through each of the injection holes 7, 8 to make its ignition and combustion.

Description

Detailed Description of the Invention: Even when the present invention is formed into a vertical vaporizing cylinder, the state of raw combustion automatically shifts to the state of vaporizing combustion by the replenishing action of combustion air and the atomizing action of fuel oil. This invention relates to a vertical vaporizing burner that can expand the range of the vaporizing combustion flame.

First, the present applicant proposed an upper pipe having a clay pipe with an air outlet on the negative side and a vaporization chamber inside, and a combustion section with a gas chamber inside and a combustion part for directing vaporized combustion flames to the upper pipe. The pipes are connected in a continuous manner to form an overall approximately U-shape, and the tip of the molten oil supply pipe is visible inside the clay pipe on the air outlet side.
We have developed a vaporizing burner that automatically shifts fuel from a raw burning state to a vaporizing combustion state by replenishing combustion air and feeding fuel.

However, the above-mentioned vaporizing burner includes a clay pipe for evaporating fuel by preheating and converting the generated vaporized gas into hot gas, and an upper pipe for blowing out the mixed gas generated inside the clay pipe. Is it because they are installed horizontally one above the other, or is the vaporizing combustion flame emitted from the upper pipe rounded up so that it is concentrated in the upper pipe in order to continue generating hot gas over a long period of time? It is something that

Therefore, in conventional vaporizing burners of this kind, the occupied area is large, or the heat radiation area of the vaporizing combustion flame is small, so that they cannot be installed in heating equipment or the like where the combustion chamber is long in the vertical direction.

In view of the above, the present invention makes the tip side of a vertical vaporizer tube with an air outlet on the base end side vertically parallel to the nuclear vertical vaporizer tube, and further includes a combustion section that heats the outer periphery of the vertical vaporizer tube. It is connected to a vertical gas chamber body equipped with a vertical vaporizing cylinder and a combustion part for cutting out a vaporizing combustion part on the opposite side, and a spray nozzle is installed inside the vertical vaporizing cylinder located on the air outlet side. Even if the combustion chamber is long in the vertical direction, the fuel can be kept in a live combustion state by the replenishing action of combustion air and the blowing back action of the fuel, without using any rotating parts. More automatically vaporized combustion II
Vertical evaporation not only allows for K transition, but also allows for a long-term continuation of the evaporative combustion state while easily expanding the flame area of the evaporative combustion section, making it possible to provide an effective heating source at a low cost. The structure of a vertical vaporizing burner according to the present invention will be described below with reference to a preferred embodiment shown in the accompanying drawings.

1 and 2, reference numeral 1 denotes a hollow vertical vaporizer tube with an air outlet 2 at its base end, and a tip a"i of the vertical vaporizer tube 1 and a skeleton vertical vaporizer tube 1. A combustion section 5 which has a parallel vertical shape, has a gas chamber 4 inside, and has a combustion section 5 that heats the outer periphery of the vertical vaporizer tube 1 over the entire length or part of the side facing the vertical vaporizer tube 1. It is connected to the base end side of a vertical gas chamber body 30, which is provided with a combustion section 6 for cutting off the vaporized fuel '48@ on the entire length or a part thereof on the opposite side of the vaporization tube 1.The above-mentioned combustion section 5.6 is Both are formed by drilling a large number of gas ejection holes 7.8, and the distal end side of the vertical gas chamber body 3 is sealed.

Note that one or more of the above vertical gas chamber bodies 3 may be provided on the outer periphery of the vertical vaporization cylinder 1 at a cutout interval 9,
In the embodiment of the present invention, four vertical gas chamber bodies 3...
... are shown installed at equal intervals around the circumference of the vertical vaporization tube 1. Furthermore, the cross-sectional shapes of the vertical vaporization tube 1 and the vertical gas chamber body 3 may be arbitrary. Moreover, if the combustion part 5.6 is formed of ceramic, the combustion part 5.6
More infrared rays can be emitted.

A spray nozzle 10 capable of spraying fuel upwardly inside the vertical vaporizer tube 1 is disposed inside the vertical vaporizer tube 1 in the vicinity of the base end air outlet 2. An ignition plug 11 is provided near the tip, and live combustion is caused in the vertical vaporizing cylinder 1 where the fuel is sprayed.

Reference numeral 12 denotes a fuel oil flow prevention wall protruding from the inner surface of the vertical vaporizing cylinder 1 in the vicinity of the spray nozzle 10.

Reference numeral 13 denotes a flame abutment plate for accurately cutting off the combustion part ejected from the combustion part 5.6 in the target direction, and the flame abutment plate 13 is connected to the gas ejection hole 7 which becomes the combustion part 5.6. , 80 are installed at both end positions.

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

Now, combustion air is blown into the vertical vaporizer cylinder 1 from the air outlet 2 side in the direction of the arrow, and at the same time, fuel oil is sprayed into the vertical vaporizer cylinder 1 in the form of fine particles through the spray nozzle 10, and then ignited. The plug 11 is used to start the ignition.

Then, the raw combustion flame generated at the same time as raw combustion occurs in the vertical vaporizer cylinder 1 enters the vertical gas chamber 4, and then a part of the raw combustion flame is transferred to the combustion section. The vertical vaporizer cylinder IK ejects flame from the multiple gas injection holes 7 . . . The flames are emitted all at once in the opposite direction to cylinder 1. As a result, the vertical vaporizer tube 1 is heated from the inside and outside by the live combustion flame, and the temperature inside the vertical vaporizer tube 1 is raised to a vaporizing atmosphere temperature sufficient to quickly vaporize the fuel. The mold gas chamber body 3 is also heated to a temperature at which the vaporized gas is not liquefied.

If such a state occurs, the spraying action of the fuel from the spray nozzle 10 and the energizing action to the ignition plug 11 are temporarily stopped to interrupt live combustion, and then the spray nozzle 10 is again used to spray the fuel into the vertical fuel vaporization tube 1. If the fuel oil is blown into the interior, the fuel oil will quickly evaporate and vaporize as it is injected into the vertical vaporization tube 1 along with the combustion air in the direction of the arrow, and the vaporized gas will be released into the circulating combustion air. The gas is stirred and mixed to become a completely humid gas, and is then pressurized into the gas chamber 4 of the vertical gas chamber body 3. Under a constant pressure state, it is released from the combustion section 5 into the vertical gas chamber. At the same time, other humid gas is ejected from the combustion section 6 in the opposite direction to the vertical vaporization tube 1.

Therefore, if the humid gas spouted out as described above is ignited by an appropriate igniter, the vertical vaporizer tube 1 will be constantly preheated from the surroundings by the combustible vaporization combustion field, and from then on, the vertical vaporizer tube 1
Not only can the gas ejected into the combustion chamber be superoxidized to continuously maintain good vaporization combustion, but also the swidden fields can be eaten over a wide area through one combustion section 6.

Therefore, even if the vaporizing burner that transfers fuel oil from a raw combustion state to a vaporizing combustion state is of a vertical type without using a rotating member, vaporizing combustion with a large heat dissipation area can be continued satisfactorily over a long period of time.

In short, the present invention has a vertical vaporizing tube 1 whose base end @ is the air outlet 2, and whose distal end is parallel to the vertical vaporizing tube 1, and which burns to heat the outer periphery of the vertical vaporizing tube 1. The part 5 is connected to the vertical gas chamber body 3 which is equipped with the combustion part 6 for cutting off the vaporized flame on the opposite side of the vertical vaporizing tube 1, and the air outlet 2@
Since the spray nozzle 10 is disposed inside the vertical vaporization tube 1 located at Perhaps it is possible to make vaporization combustion possible by cutting off a part of the vaporization combustion field that has been generated into the vertical vaporization tube 1, which preheats it and generates it continuously without interrupting the generation of humid gas. Of course, it is possible to make a part of the vaporization combustion field continue to emit flames in the opposite direction to the vertical vaporization tube 1, and to expand the heat radiation range of the vaporization combustion field. As a result, even if the heating device has a long combustion chamber in the vertical direction, it can be easily installed and an effective heating operation can be achieved.
