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.

いる。 Further, the outlet side of the vaporizer V is connected to the load side L of a boiler etc. through a supply pipe 3 with an on-off valve 4 interposed therebetween, and the vaporizer V is connected to the load side L of a boiler etc. )
A heat medium feed pipe 5 that introduces the heat medium and a heat medium discharge pipe 6 that discharges the heat medium are connected.
By circulating room temperature water through the vaporizer V, the liquid fuel 2 can be heated and vaporized.

に低温化することになる。 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, the pressure inside the fuel tank T is gradually reduced, and the temperature of the liquid fuel 2 is gradually lowered based on the pressure reduction. become.

を充分気化させることができる。 If such a supply state of vaporized gas continues, the resulting pressure reduction in the gas phase section 12 will operate the gas-liquid automatic switching valve 10, thus closing the vaporized gas feed pipe 11 and discharging the liquid fuel. Feed pipe 1 and guide pipe 1
3 are automatically switched to a state where they are in communication. Therefore, the liquid fuel 2 passes from the feed pipe 1 through the valve 10 and the guide pipe 13 to the vaporizer V.
and is heated and vaporized by the heating medium introduced into the vaporizer V. In this example,
As mentioned above, even if room temperature water such as well water is used as a heat medium, as mentioned above,
Since the temperature of the liquid fuel 2 decreases due to the reduced pressure inside the fuel tank T, even if water at room temperature of about 15°C is used, the temperature difference between the liquid fuel 2 and the heat transfer medium becomes large, and as a result, due to the temperature gradient, the temperature decreases rapidly. Heat exchange is performed by thermal conduction, and liquid fuel 2 does not need to be a high-temperature heat carrier.
can be sufficiently vaporized.

A gas-liquid automatic switching valve 10 is provided between the gas phase section 12 and the gas-liquid automatic switching valve 10, which switches from the vaporized gas flow state to the liquid fuel flow state due to a drop in gas pressure in the gas phase section 12. The fuel gas can be used on the load side L without preheating the vaporizer V because it is connected to the vaporizer V which is connected to the vaporizer V and is equipped with the heat medium feed path 5 to which the heat medium is supplied. In this case, the natural vaporized gas can be used effectively to meet the demand, and if the natural vaporized gas becomes diluted and the liquid fuel 2 is supplied to the vaporizer V, at this point the heat If the medium is supplied to the vaporizer V, as described above, in the present invention, the gas phase part 12
Since the temperature of the liquid fuel 2 is lowered by using the pressure drop of As a result, the amount of commercial energy consumed and the amount of heat medium used can be significantly reduced, thereby making it possible to lower the running cost of this type of device and providing a simple operation.
