As the valve 6 is opened and closed, the fuel 2 may or may not be supplied to the combustion device 4 from the fuel tank 1. Such supply or non-supply may be determined depending on the supply state of the mixed fuel. That is, if the mixed fuel supply state is good, the valve 6 is in the "closed" state, and if the mixed fuel supply state is not good, the valve 6 can be in the "open" state. Therefore, when the supply state of the mixed fuel is not good, the fuel 2 can be directly supplied to the combustion device 4 so that the combustion in the combustion device 4 can be properly maintained.

The volume ratio of the additive 18 to the mixture of the fuel 2 and the water 15 is in the range of 0.25% to 0.45% (most preferably 0.3%).

The stirring tank 10 may further be included. The stirring tank 10 can stir the fuel 2, the water 15 and the additive 18 supplied therein. The stirring tank 10 may include a stirring blade 11 capable of rotating in the stirring tank 10 and a motor 12 for driving the stirring blade 11. In the stirring tank 10, Is not limited to this. It is also possible to stir the fuel 2, the water 15 and the additive 18 by using the pressure when the fuel 2, the water 15 and the additive 18 are supplied to the stirring tank 10, And the additive 18 are sprayed upward so that they are agitated.

Inside the stirring tank 10, a level sensor 38 for detecting the water level of the agitation liquid may be provided.

When the stirring in the stirring tank 10 is completed, the mixing liquid of the stirring tank 10 (i.e., the mixed fuel produced by mixing the fuel 2, the water 15 and the additive 18) Through the same mixed fuel discharge pipe 29, reaches the filter 33 (which may be a Teflon (registered trademark) filter of 1 m) and is filtered and stored in the mixed fuel tank 34 .

For this purpose, a mixed fuel discharge pipe 29 may be further included. The mixed fuel discharge pipe 29 is provided with a solenoid valve 30 for opening and closing the solenoid valve 30, a pump 31 for transferring the throat fluid, a flow meter 32 for measuring the flow rate in the mixed fuel discharge pipe 29, May be provided.

A second bypass 36 may be further included. This can be connected between the portion of the fuel supply pipe 5 between the combustion device 4 and the valve 6 and the mixed fuel tank 34. Therefore, the second bypass 36 can supply the mixed fuel 35 from the mixed fuel tank 34 to the combustion device 4. [ The second bypass 36 may be provided with a manual valve 41. The mixed fuel 35 can be supplied to the combustion device 4 by setting the valve 6 to the "closed" state and the manual valve 41 to the "open" state.

3 is a flowchart showing a mixed fuel supply method according to an embodiment of the present invention.

In the initial state, the valve 6 of the fuel supply pipe 5 is in the "closed" state, the solenoid valves 23, 24, 25, 30 are in the " (If the mixed fuel supply state is not good, the combustion in the combustion device 4 can be maintained through the direct supply of the fuel 2 as described above, but in the following description, Only the case where the mixed fuel supply state is good will be described).

First, it can be checked whether the lower limit sensor 40 is in the ON state (S1). If the lower limit sensor 40 is in an ON state, a sufficient amount of the mixed fuel 35 exists in the mixed fuel tank 34, so that a special additional operation may not be required. However, if the lower limit sensor 40 is in the OFF state, it may be necessary to replenish the mixed fuel to the mixed fuel tank 34 because the mixed fuel 35 will shortage soon.

To this end, it is possible to check whether the level sensor 38 is in the ON state (S2). If the level sensor 38 is in the OFF state, the fuel 2, the water 15 and the additive 18 in the stirring tank 10 are not sufficient. Therefore, the fuel 2, the water 15 and the additive 18 ) To the stirring tank 10 can proceed (S3). Specifically, the fuel 2, the water 15 and the additive 18 can be supplied to the stirring tank 10 by bringing the solenoid valves 23, 24 and 25 into the "open" state. In this case, the flow rate of the fuel 2, the water 15, and the additive 18 can be adjusted by the flow meters 26, 27 and 28 so that the mixture ratio becomes a predetermined value. In particular, the water 15 in this case may be water in which the molecular aggregate is subdivided via the water conversion unit 100.

If the level sensor 38 is turned on in step 2 (S2), the fuel 2, the water 15 and the additive 18 are brought into a "closed" state by the solenoid valves 23, 24, And the stirring may be performed for a predetermined time (for example, 10 minutes) (S4).

When stirring is performed, the pump 31 may be operated to bring the solenoid valve 30 into the "open" state (S5). As a result, the mixed fuel produced by stirring the fuel 2, the water 15 and the additive 18 can be discharged from the stirring tank 10 and filtered by the filter 33. The filtered mixed fuel can be made into fine particles and stored in the mixed fuel tank 34. In this case, the flow rate of the mixed fuel can be measured by the flow meter 32 of the mixed fuel discharge pipe 29.

Then, it is possible to check whether the upper limit sensor 39 is in the ON state (S6). If the upper limit sensor 39 is off, the pump 31 can be continuously operated until the upper limit sensor 39 is turned on. If the upper limit sensor 39 is on, it may mean that the mixed fuel 35 is sufficiently stored in the mixed fuel tank 34. [ In this case, the pump 31 can be stopped and the solenoid valve 30 can be brought into the "closed" state (S7).

Then, it is determined whether or not the supply of the mixed fuel 35 is to be terminated (S8). If the supply of the mixed fuel 35 is not to be terminated, the flow returns to the step S1 (S1).

The mixed fuel 35 can be supplied to the combustion device 4 through the fuel supply pipe 5 by bringing the manual valve 41 into the "open" state. The combustion apparatus 4 can combust the supplied mixed fuel 35. [

When the mixed fuel 35 in the mixed fuel tank 34 is reduced and the lower limit sensor 40 is turned off as the combustion continues in the combustion device 4, the processes in step 2 (S2) and subsequent steps are repeatedly performed .
