Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a liquid fuel combustion apparatus in which the amount of combustion in a burner is automatically controlled in response to the temperature of an object to be heated.

Conventional configuration and its problems In conventional combustion devices of this type, the valve ratio is varied in response to the temperature of the heated object, thereby adjusting the amount of fuel supplied to the burner and controlling its combustion amount. Most of them were.

However, the above control method inevitably has poor responsiveness.
Therefore, there is a drawback that the temperature variation of the heated object becomes large. OBJECTS OF THE INVENTION The present invention eliminates the drawbacks of such a secondary structure, and provides a liquid fuel combustion apparatus that can accurately control the temperature of a heated object.

Structure of the Invention The liquid fuel combustion device of the present invention includes a burner and a vaporizer that vaporizes the liquid fuel using the combustion heat of the burner, and the vaporizer is movable so as to be freely movable relative to the burner. It is connected to a thermal reactor that supports the burner and responds to the temperature of the heated object heated by the burner.

Therefore, the distance between the vaporizer and the burner changes in response to the temperature of the heated object, and the influence of combustion heat on the vaporizer is controlled, thereby automatically adjusting the firepower of the burner. It is something.

Description of examples Examples thereof will be described below with reference to the accompanying drawings.

The figure shows a burner applied to a catalytic combustion system; 1 is a burner constructed by providing a catalyst layer 3 in a porous case 2; It supports an oxidation catalyst such as palladium. 4 is the spark plug, 5 is the fuel tank, 6
1 is a carburetor having a vaporized fuel outlet 7 on its upper surface, and this carburetor 6 and a fuel tank 5 are connected through a movable lamp wick 8.

The carburetor 6 is located directly below the burner 1 so as to be affected by its combustion heat, and is supported by two guide punches 9 so as to be vertically movable. 1 a spring that attaches the vaporizer 6 upwardly, that is, in a direction approaching the burner 1; 11 a heated body heated by the burner 1; 12 a vaporizer that responds to the temperature of the heated body 11; 6 is a thermal reactor that presses downward.

In the above configuration, when gaseous fuel is initially supplied to the catalyst layer 3 of the burner 1 and ignited by the spark plug 4, flameless combustion is started by the catalytic action.

By combustion in such a burner, the vaporizer 6 is heated together with the object to be heated 11. Therefore, the liquid fuel sucked up from the fuel tank 5 into the vaporizer 6 via the wick 8 is vaporized by the heat of the burner, and is fed to the burner 1 as vaporized fuel.

Of course, at this time, combustion air is also supplied to the burner at the same time, and combustion in the burner continues with the above operation. When the heated body 12 attempts to rise above the set temperature due to heating by the burner, the thermal reactor 12 moves the vaporizer 6 downward against the spring 10'. However, since the influence of combustion heat on the vaporizer 6 is reduced, the amount of combustion vaporized is also reduced, and the combustion output of the burner 1 is reduced.

Conversely, when the temperature of the heated body 12 falls below the set value, the pressing force exerted by the thermal reactor 12 weakens, and the vaporizer 6 approaches the burner 1, increasing the combustion output. By varying the distance between the burner 1 and the vaporizer 6 in this way, the amount of vaporized liquid fuel is adjusted and the combustion output of the burner 1 is controlled. Incidentally, the burner is not limited to the supercharged catalytic combustion method, and equivalent functions and effects can be expected with a flaming combustion method.

Effects of the Invention As described above, according to the present invention, the amount of fuel vaporized is controlled by varying the distance between the burner and the vaporizer and adjusting the influence of combustion heat on the vaporizer. The burner combustion output is sensitively linked to the temperature, making it possible to control the temperature of the heated object without variation.
