Description

[Detailed description of the invention] The present invention relates to a device for vaporizing light oil such as kerosene.

In conventional light oil vaporizers, the temperature is controlled by controlling the output of an electric heater or the like using a temperature detector installed in the evaporator to adjust the amount of evaporation.

Therefore, a heating device (such as an electric heater) to evaporate the light oil and a device (such as a temperature detector) to control the temperature are required, and the cost of the device itself is high (and the structure is prone to failure). It had the disadvantage that it could not be obtained.

The present invention has been made in view of the above-mentioned drawbacks, and its purpose is to provide a light oil vaporization device that can perform temperature control simply, reliably, and at low cost.

The present invention will be described in detail below based on the drawings shown as examples.

Reference numeral 1 denotes an evaporation chamber, and a fuel supply pipe 2 is connected to the evaporation chamber 1, so that fuel such as kerosene flows into the evaporation chamber 1.

As this evaporation chamber 1 is heated, the fuel that has flowed into the interior evaporates, and the evaporated gas is led to the burner 4 from a take-out pipe connected to the evaporation chamber 1, and is ignited by an appropriate ignition means (for example, a matchstick). be burned.

The surface of the evaporation chamber 1 is heated by the burner thermal power, and the inside of the evaporation chamber 1 is further heated to continuously evaporate (vaporize) the fuel.

In addition, when starting, use an appropriate heating means (e.g. electric heater, etc.)
The inside of the evaporation chamber 1 is heated by this, and when the inside of the evaporation chamber 1 is sufficiently heated by the burner thermal power, the heating means may be removed (stopped).

In addition, the burner thermal power is consumed to heat the inside of the evaporation chamber 1 as described above, but most of it is consumed by the heat exchanger (e.g. boiler etc.) 5.
consumed for heating.

Reference numeral 6 denotes an expansion chamber, which is provided so that heat is conducted to the evaporation chamber 1 via a heat transfer section 7.

That is, the heat transfer section 7 formed protruding from the expansion chamber 6 is connected to the evaporation chamber 1.
The heat stored in the evaporation chamber 1 is transferred to the heat transfer section 7.
from there to the expansion chamber 6.

Thus, a pressure change within the expansion chamber 6 occurs.

This pressure change is transmitted from the connecting pipe 9 to the throttle valve 9 provided in the outlet pipe 3 near the bottom of the burner 4, and adjusts the evaporated gas supplied from the outlet pipe 3 to the burner 4.

Specifically, when the heat in the evaporation chamber 1 is transferred to the expansion chamber 6 via the heat transfer section 7, the pressure in the expansion chamber 6 increases, and the throttle valve 9 responds to this by supplying heat from the extraction pipe 3. The evaporated gas is reduced (that is, the throttle valve 9 is throttled), and the firepower of the burner 4 is weakened.

Then, the temperature inside the evaporation chamber 1 gradually decreases. As the temperature in the evaporation chamber 1 decreases, the pressure in the expansion chamber 6 decreases, and the throttle valve 9 responds to this by increasing the amount of evaporated gas (that is, the throttle valve 9
Open () and increase the firepower of burner 4.

Thereafter, the temperature is automatically adjusted by repeating this process.

Similarly, when a heat pipe is used as the heat transfer section 7, it has excellent heat conduction, and therefore has the advantage that, for example, the distance between the evaporation chamber 1 and the expansion chamber 6 can be increased.

FIG. 2 shows another embodiment, in which an expansion chamber 6 is provided within the evaporation chamber 1 to save space and prevent heat radiation from the expansion chamber 6.

Although air is normally sealed in the expansion chamber 6, a small amount of high boiling point (260 to 300°C) liquid is also sealed at the same time (thereby, the responsiveness of the throttle valve 9 can be improved).

As described above, there is provided a light oil vaporization apparatus which evaporates light oil in an evaporation chamber and guides the evaporated gas to a burner to heat the evaporation chamber and continuously vaporize the light oil. The light oil vaporizer according to the present invention has the following features: The heat stored in the burner is transmitted to the expansion chamber and the throttle valve of the burner is adjusted according to the pressure change in the expansion chamber. reached.

1) It is possible to adjust the thermal power without using energy such as electricity, and it is inexpensive.

2) Simple structure and less risk of failure.

3) The heat required for vaporizing the fuel can be obtained mainly from the fuel itself, so it is inexpensive.
