Thereafter, the water and oil stored in the water tank 20 and the petroleum tank 30 by the operation of the pumps 29 and 39 are each line, that is, the water is the first line 21 and the first valve assembly 23. And a second line 22 is supplied into the first vaporization chamber 50A-1, and the oil is supplied through the third line 31, the second valve assembly 33, and the fourth line 32. It is supplied into the vaporization chamber 50A-2.

Water and oil supplied into each of the vaporization chambers 50A-1 and 50A-2 are heated by the heater H and vaporized into water vapor and oil gas. Water vapor and oil gas in the vaporized state are raised to the upper portion of each of the vaporization chambers 50A-1 and 50A-2 and are supplied to the combustion chamber 50B through the respective vaporization nozzles 53A and 53B mounted at the upper end. Hot steam and oil gas injected into the combustion chamber 50B through the respective vaporization nozzles 53A and 53B spontaneously ignite during the injection process, and in particular, the air supplied to the combustion chamber 50B through the air regulator 40 is steam. And combustion of oil gas.

FIG. 3 is a schematic diagram for explaining the function of each valve assembly shown in FIG. 1, wherein the first valve assembly 23 and the second valve assembly 33 have the same configuration and function, and thus, the first assembly. Bay 23 will be described as an example.

A separate return line 24 is connected to the first valve assembly 23 connecting the first line 21 and the second line 22 to supply water to the vaporization chamber 50A-1. One end of the line 24 is connected to the water tank 20. When the opening and closing degree of the valve provided in the first valve assembly 23 is adjusted, the amount of water supplied to the vaporization chamber 50A-1 may be adjusted. That is, if the opening degree of the valve is reduced to lower the combustion temperature, the amount of water discharged to the second line 22 is reduced. However, since the amount of water supplied to the first valve assembly 23 through the first line 21 is always constant, the excess water, that is, water that does not flow into the vaporization chamber 50A-1 through the second line 22, is provided. Is re-introduced into the water tank 20 through the return line 24. The same function can be obtained in the second valve assembly 33 which controls the amount of oil supplied.

In particular, by adjusting the amount of oil and water supplied to each of the vaporization chambers 50A-1 and 50A-2 through the two valve assemblies 23 and 33, the amount of vaporized oil gas and water vapor can be adjusted to control the combustion chamber ( It is possible to maintain an optimum combustion state within 50B).

As described above, the heat of combustion can sufficiently vaporize the water and oil supplied by heating the respective vaporization chambers 50A-1 and 50A-2 in the course of the vaporization of the vaporized oil and the oil gas in the combustion chamber 50B. Therefore, even after the combustion is started, even if the operation of the heater (H) is stopped, the water and oil vaporization of the oil continues of course.

The present invention as described above can improve the combustion efficiency by supplying a high temperature vaporized gas to the combustion chamber after the oil and water vaporized by a heater, in particular, by controlling the supply amount of water and oil to effectively control the combustion temperature as well as the margin By returning the fuel to each tank, the effect of preventing the waste of fuel can also be obtained.
