している。 As shown in FIG. 1, a conventional device of this type connects a fuel tank T and a vaporizer V through a liquid fuel supply pipe 1, and supplies liquid fuel 2 in the fuel tank T to the vaporizer V. The liquid fuel 2 is vaporized by the vaporizer V, and the fuel gas obtained thereby is supplied to the load side L through the supply pipe 3. In the figure, 4 indicates an on-off valve installed in the supply pipe 3; Reference numeral 5 indicates a heat medium feed pipe for supplying a heat source such as steam to the vaporizer V, and reference numeral 6 indicates a discharge pipe thereof.

るしく嵩むという問題を有していた。 However, when using such a conventional fuel gas supply device, the vaporizer V supplies liquid fuel 2.
In order to vaporize immediately, the vaporizer V must be preheated to the required temperature even when fuel gas is not supplied to the load side L, and therefore a heat medium such as steam must be constantly supplied. , the running cost is high, and since the liquid fuel 2 must be directly sent to the vaporizer V and vaporized, a large amount of thermal energy is also required for the heating medium, and as a result, a large amount of thermal energy is required for the heating. A large amount of commercial energy is consumed for steam generation, etc., which, together with the running cost, causes problems such as low operating efficiency of the entire device and a significant increase in operating costs.

ライザＶの入口側が連通接続されている。 This fuel tank T includes a liquid fuel feed pipe 1 that feeds liquid fuel 2 to the vaporizer V side, and a liquid fuel feed pipe 1 that is opened to a gas phase portion 12 of the tank T to send the vaporized gas to the vaporizer V side. The vaporized gas feed pipes 11 to be supplied are connected to each other separately, and a predetermined set pressure (approximately 2 kg/

熱媒体排出管６から排出される。 Furthermore, the outlet side of the vaporizer V is connected to the load side L of a boiler or the like through a supply pipe 3 with an on-off valve 4 interposed therebetween, and the vaporizer V is supplied with room temperature water (for example, well water of about 15°C) as a heat exchange medium. An automatic opening/closing valve 14 such as a solenoid valve is installed in the heat medium feed pipe 5 for introducing the heat medium.
The heat medium that has completed heat exchange in the vaporizer V is
The heat medium is discharged from the heat medium discharge pipe 6.

ものである。 Here, the automatic opening/closing valve 14 is connected to a pressure sensing element 15 such as a pressure gauge installed in the liquid fuel feed pipe 1, and is controlled to be turned on and off.
つまり、圧力検知素子１５は、予め定めてある

る。 In other words, the pressure sensing element 15 issues a signal when the liquid pressure in the liquid fuel supply pipe 1 becomes lower than a predetermined pressure value, and switches the automatic opening/closing valve 14 from the previous closing position. It is configured such that the heating medium can be supplied from the heating medium feed pipe 5 to the vaporizer V by operating the heating medium from the open state to the open state.

足できることになる。 Therefore, when operating the device according to the above embodiment and supplying fuel gas to the load side L, first operate the on-off valve 4 to open the supply pipe 3.
is open to the atmosphere via the load side L. On the other hand, in the gas phase part 12 of the fuel tank T, the liquid fuel 2 is naturally vaporized and is in a high pressure state (approximately 5 to 7 kg/cm 2
G), the gas-liquid automatic switching valve 10 is actuated by the pressure of the vaporized gas, and thereby the vaporized gas supply pipe 11 and the guide pipe 13 are connected to each other. is in communication state,
The vaporized gas is fed through the path of vaporized gas supply pipe 11 - gas-liquid automatic switching valve 10 - guide pipe 13 - vaporizer V - supply pipe 3 - load side L, and therefore, as described above, the on-off valve 4 At the same time as opening, fuel gas is supplied by natural vaporization, and the demand on the load side L can be satisfied.
このような気化ガスの供給状態が続くと、燃料
タンクＴの気相部１２は次第に減圧され、当該減
圧に起因して液体燃料２、すなわち液相部１２の
温度は降下していくことになる。 If such a supply state of vaporized gas continues, the pressure in the gas phase portion 12 of the fuel tank T will gradually decrease, and the temperature of the liquid fuel 2, that is, the liquid phase portion 12 will decrease due to the pressure reduction. .

料２がベーパライザＶへ供給される。 Further, as described above, when the reduced pressure in the gas phase section 12 causes the gas-liquid automatic switching valve 10 to switch, the vaporized gas feed pipe 11 is closed, and the liquid fuel feed pipe 1 is opened. The feed pipe 1 and the guide pipe 13 are brought into communication, and the liquid fuel 2 is now supplied from the liquid fuel feed path 1 to the vaporizer V.

が供給管３を通じて負荷側Ｌに送給される。 In synchronization with the gas-liquid supply switching operation as described above, the pressure sensing element 15 detects a decrease in the pressure in the liquid phase due to the pressure drop in the gas phase 12, and this causes the automatic opening/closing valve 14 to operate as described above. Then, the heat medium supply pipe 5 is opened, the heat medium flows into the vaporizer V, heats and vaporizes the liquid fuel 2 that has flowed into the vaporizer V, and fuel gas is supplied by this forced vaporization. It is fed to the load side L through the pipe 3.

熱交換が行なわれ、高温熱媒体でなくとも液体燃
料２を充分気化させることができるからである。 In this invention, as in the above embodiment, room temperature water, such as well water, can be used as the heat medium, but this is because the liquid fuel 2 is lowered in temperature by the pressure reduction in the gas phase part 12 of the fuel tank T, as described above. Therefore, even if you use room temperature water, which is as low as 15℃,
This is because the temperature difference between the liquid fuel 2 and the heat medium increases, and as a result, the temperature gradient causes rapid heat exchange through heat conduction, and the liquid fuel 2 can be sufficiently vaporized even if it is not a high-temperature heat medium. be.

媒体のベーパライザＶへの送給は停止される。 In addition, when stopping the supply of fuel gas, it is sufficient to close the on-off valve 4, and thereby the supply of liquid fuel 2 is stopped and the gas phase section 1 of the fuel tank T is closed.
2 is increased in pressure, the automatic gas-liquid switching valve 10 is switched, and the automatic opening/closing valve 14 is operated by the pressure sensing element 15 to close the heat medium feed pipe 5 and feed the heat medium to the vaporizer V. will be stopped.

り、その操作も簡便なものを提供し得る。 As explained above, this invention consists of a liquid fuel feed path 1 that opens to the liquid fuel 2 in the closed fuel tank T, and a vaporized gas feed path 11 that opens to the gas phase portion 12 of the tank T. In between, a gas-liquid automatic switching valve 10 is provided which switches from a vaporized gas flow state to a liquid fuel flow state due to a drop in gas pressure in the gas phase section 12, and the switching outlet side of the switching valve 10 is connected to the load side L. Connected to a vaporizer V equipped with a heat medium feed path 5 to which a heat medium is supplied,
Since the automatic opening/closing valve 14 provided in the heat medium feed pipe 5 can be opened and closed by the pressure detection signal from the pressure detection element provided in the liquid fuel feed path 1, the vaporizer V does not need to be preheated. When fuel gas is to be used on the load side L, the demand can be met by effectively utilizing the naturally vaporized gas, and the naturally vaporized gas becomes diluted and the liquid fuel 2 is supplied to the vaporizer V. When the automatic opening/closing valve 14 is automatically opened, the heat medium is supplied to the vaporizer V in a timely manner, and the gas phase section 12 is automatically opened.
Since the temperature of the liquid fuel 2 is lowered by using the pressure drop of As a result, the consumption of commercial energy and the amount of heat medium used can be significantly reduced, making it possible to lower the running costs of this type of equipment and providing simple operation. .
