Description

[Detailed description of the invention] Industrial application field The present invention prevents combustion flames from concentrating in the center by blowing cooling air into the fuel cup at any time in an amount commensurate with the amount of combustion. By separating a part of the clean combustion air blown into the ventilation chamber and sending it into the cooling ventilation chamber, it is possible to prevent carbon from adhering to the fuel cup, etc., resulting in stable combustion over a long period of time. This invention relates to a rotary burner that can maintain a combustion state.

BACKGROUND ART Conventionally, a cooling air blowing chamber 8 was separately provided in the air blowing chamber 4, and the cooling air introduced into the cooling air blowing chamber 8 was blown into the fuel cup 5.
A rotary burner is known as shown in Fig. 2, which prevents burnout of the fuel cup 5 and prevents tar and carbon from adhering to the inner surface of the fuel cup 5 to continue stable combustion. It's summery. That is, a blower chamber 4 connected to the combustion tube 1 is provided on the base end side of the combustion tube 3 facing the intake side b of the hot air generation cylinder 1 which has a suction blower impeller 2 rotatably mounted on the discharge side a. A fuel cup 5 is rotatably provided in the ventilation chamber 4, and a partition cup 6 is provided inside the ventilation chamber 4, which is integrally attached to the outer back side of the fuel cup 5.
A cooling ventilation chamber 8 is provided by a partition wall tube 7 arranged at the base end side of the ventilation chamber 4, and a plurality of ventilation holes 9 communicating with the cooling ventilation chamber 8 are opened in the fuel cup 5. Clean combustion air is blown into the ventilation chamber 4 through the blast tube 11 of the burner fan 10, and at the same time, dirt, dust, etc. are contained through the ventilation window 12 opened on the back side of the cooling ventilation chamber 8. Cooling air is introduced by the suction action of the suction blower wheel 2, and the cooling air is blown into the fuel cup 5 through the ventilation holes 9.

Problems that the invention aims to solve By the way, in conventional rotary burners of this type, the cooling air sent into the cooling and ventilation chamber is drawn from outside air that is not purified in any way by the suction action of the suction blower impeller. Perhaps because of this, the amount of cooling air commensurate with the amount of combustion cannot be sent into the cooling ventilation chamber, so at the time of maximum combustion, the amount of cooling air is insufficient.
The problem is that combustion flames are concentrated in the center, which accelerates the burnout of the fuel cup, and dirt and dust adhere to the fuel cup, accelerating the generation of carbon, making it impossible to maintain stable combustion over a long period of time. It was hot.

Means for solving the problems The present invention solves the above problems, and includes:
The configuration will be explained below with reference to FIG. 1 corresponding to the embodiment.

That is, a blowing chamber 102 connected to the combustion tube 101 is provided on the proximal end side of the combustion tube 101 with its tip side open. A fuel cup 107 is rotatably provided within the combustion tube 101. The above ventilation chamber 102
Inside, a cooling ventilation chamber 110 is provided by a partition cup 108 integrally attached to the outer back side of the fuel cup 107 and a partition wall cylinder 109 disposed on the base end side of the ventilation chamber 102. The cooling ventilation chamber 110 communicates with the interior of the fuel cup 107 through a plurality of ventilation openings 111. Between the partition cup 108 and the partition wall tube 109, a part of the clean combustion air sent into the ventilation chamber 102 by a burner fan 113 having a filter 115 stretched over the intake window 114 is transferred to the cooling ventilation chamber 110. Ventilation passage 11 that blows air inside
2.

Operation First, when starting combustion, clean combustion air obtained by the burner fan 113 having a filter 115 stretched over the intake window 114 is blown into the ventilation chamber 102 . Then, the clean combustion air blown into the ventilation chamber 102 is separated in the ventilation chamber 102, and one of them is blown from the ventilation chamber 102 into the combustion tube 101, while the other clean combustion air is blown. After being blown into the cooling ventilation chamber 110 through the passage 112, it is ejected into the rotating fuel cup 107 through the plurality of ventilation ports 111. Therefore, if the fuel oil is sent to the inner surface of the fuel cup 107, the fuel becomes fine particles due to the centrifugal force effect due to the rotation of the fuel cup 107 and the jetting action of clean combustion air, and is injected toward the inner circumferential surface of the combustion tube 101. It is dispersed and combusted by ignition. And by promoting combustion, the fuel cup is reduced by 10%.
7 is heated by a combustion flame.

By the way, from the start of the burner, a part of the clean combustion air is always separated in the blower chamber 102 and then blown into the cooling blower chamber 110 through the blower passage 112.
The cooling air sent into the cooling air chamber 110 is increased or decreased in accordance with the increase or decrease in the amount of clean combustion air sent into the air blowing chamber 102, so that an amount of clean cooling air commensurate with the increase or decrease in the amount of combustion is sent to the cooling air blowing chamber 110 at any time. After the air is blown into the fuel cup 107, this cooled air is blown into the fuel cup 107 to prevent burnout of the fuel cup 107, or to prevent combustion flames from concentrating in the center of the fuel cup 107, thereby removing carbon generated by dirt and dust. is fuel cup 10
