Description

[Detailed Description of the Invention] The present invention relates to an improvement of a combustor vaporizer that heats and vaporizes kerosene, ejects it from a nozzle, and burns it in a Bunsen burner.

In the conventional device, an inner cylinder is placed inside an outer cylinder, a vaporization chamber is formed between the inner and outer cylinders, a heater is installed inside the inner cylinder, and the vaporization chamber has a nozzle at one end and an oil pipe at the other end. The fuel was connected to the fuel tank, and the fuel was pumped into the vaporization chamber, where it was vaporized and ejected from the nozzle. However, with conventional vaporizers, when used for a long time or when the fuel is contaminated with degraded kerosene, tar etc. adhere to the wick inside the vaporization chamber, causing the vaporization chamber to become clogged, making it impossible to vaporize the fuel. It was hot. Therefore, in a combustor using such a vaporizer, it is necessary to replace the entire vaporizer, which is an expensive burden.

The present invention was made to solve the above problem, and its purpose is to obtain a vaporizer that does not require replacing the entire device.Therefore, a removable lid is provided at one end of the outer cylinder. A small-diameter inner cylinder is inserted into the outer cylinder with its bottom facing toward the lid of the outer cylinder, and the other end of the outer cylinder and the end of the inner cylinder are closed to form a vaporization chamber between the outer cylinder and the inner cylinder. , a heater is embedded in the inner cylinder,
The vaporization chamber is connected to a temperature detection element, a nozzle at one end, and an oil supply pipe via a pump at the other end, and a coiled wick made of wire is attached from the lid side of the outer cylinder to promote fuel diffusion and vaporization. By adopting this structure, even if tar adheres to the coiled wick and the fuel cannot be vaporized, the lid of the outer cylinder can be removed and one end of the coiled wick can be pulled to create a coiled, or spiral, shape. The wick can then be pulled out of the vaporization chamber and taken out easily, and the vaporization ability can be easily regenerated by installing a new coiled wick inside the vaporization chamber, thus solving the problems of conventional vaporizers.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention.
FIG. 2 shows the coiled wick, FIG. 3 shows the coiled wick in a pulled out state, and FIG. 4 shows a sectional view taken along the line AA in FIG. 1.

First, the configuration will be explained. In Figure 1,
Reference numeral 1 denotes an outer cylinder whose one end is closed by a removable screw lid 2. 3 is a cylinder with a bottom, and is an inner cylinder having a smaller diameter than the outer cylinder 2. The inner cylinder is inserted with its bottom facing toward the lid 2 of the outer cylinder, and its end is closed together with the other end of the outer cylinder 1. 4 is a vaporization chamber formed between the outer cylinder 1 and the inner cylinder 3. Reference numeral 5 denotes a heater for heating the vaporization chamber, which is embedded in the inner cylinder 3, and a space between the heater 5 and the inner cylinder 3 is filled with a powdered heat transfer material b, such as magnesia. Reference numeral 7 denotes a heater mechanism that absorbs shocks, heat shocks, etc. applied to the heater 5. 8 is a heater gasket that prevents the powder heat transfer material 6 from flowing out, and 9 is a stopper that stops the heater gasket 8. 10 is a temperature detection element that detects the temperature of the vaporization chamber 4 and issues a signal to control the energization of the heater 5;
Reference numeral 11 designates a nozzle that injects the fuel vaporized in the vaporization chamber 4 toward a burner (not shown), 12 a fuel pipe that feeds the fuel into the vaporization chamber 4, and 13 a pump. Numeral 14 is a coil-shaped wick for quickly diffusing the fuel that has entered the vaporization chamber 4 throughout and promoting vaporization, and is installed and removed by removing the lid 2 of the outer cylinder 1.

FIG. 2 shows a coiled wick 2. In this figure, there is a gap between adjacent coils, but the structure is such that they are in close contact with each other when installed. FIG. 3 shows how the mounted wick is pulled out by radio pliers 15. Fourth
In the figure, 16 is a cleaning pin of the nozzle 11,
17 is a connecting pipe, and 18 is a solenoid for driving the cleaning pin 16.

Next, the effects of the above configuration will be explained. In FIGS. 1, 2, 3, and 4, the heater 5 is energized to maintain the vaporizing chamber 4 at a predetermined temperature, the pump 13 is operated, and fuel is supplied to the vaporizing chamber 4 through the oil pipe 12. When the fuel is fed into the fuel tank, it quickly spreads throughout the vaporization chamber 4 due to the capillary action of the coiled wick 14, and since the coiled wick 14 is also heated, vaporization occurs instantly, and the vaporized fuel flows through the nozzle. 11 toward a burner (not shown). If vaporization is carried out for a long period of time or if inferior kerosene is used as fuel, the unvaporized content of the fuel becomes tar and adheres to the fuel, reducing the vaporization ability.
In this case, in the conventional system, it was necessary to replace the entire vaporizer. In this case, the lid 2
The coiled wick 14 can be easily taken out by removing it, grasping one end of the coiled wick 14 with radio pliers 15, etc., and pulling it out. Next, by installing a new coiled wick 14, initial vaporization performance can be obtained.

As described above, according to the present invention, even if the vaporization capacity of the coiled wick in the vaporization chamber decreases due to tar adhesion, the initial vaporization performance can be maintained by removing the removable lid and replacing the coiled wick. It will be done.

In conventional systems, when the vaporization capacity deteriorates, the entire vaporization device must be replaced, and the repair costs are high. According to the invention, the coiled wick need only be replaced, the work is easy, and the cost is low.
