As shown in FIGS. 1 to 3A, the brown gas supplied to the gas storage chamber 24 is jetted from the gas jet port 26a of the nozzle 26 toward the water pipe 11. Then, when the brown gas is burned at the outer end portion of the nozzle 26, the flame thereof extends from the nozzle 26 toward the water pipe 11, and the combustion heat of the flame heats the water flowing through the flow passage 12 of the water pipe 11. It is like this. In addition, the nozzle 26 is replaced to replace the gas injection port 26

The water that has cooled the nozzle 26 overflows from the refrigerant drain pipe 30 connected to the upper end of the outer wall 22b of the burner body 22 so as to communicate with the cooling chamber 25 and is drained to the outside.

Here, the brown gas will be described. The Brown gas is a gas obtained by uniformly mixing hydrogen and oxygen gas such that the molar ratio of hydrogen and oxygen is 2: 1. The flame generated by the combustion of the Brown gas has a very high ambient temperature of 2000 to 2500 ° C. in the vicinity thereof, and a temperature of 1000 to 1500 when the temperature is further away.
It has the property of rapidly lowering to ℃. Brown gas becomes steam after combustion.

The combustion heat of the flame of Brown gas is 150
It becomes a high temperature flame of 0 to 2000 ° C. Also, the water pipe 11
The temperature inside is preferably 850 ° C. or higher, more preferably 8 by adjusting the heating power of the brown gas flame.
It is set to 50 to 1300 ° C. Then, under a high temperature condition due to the flame of Brown gas, the water flowing through the flow path 12 is rapidly heated and decomposed into hydrogen and oxygen gas, whereby a mixed gas is generated from the water.

The generated mixed gas is divided into the divided pipes 13-15.
The pressure is increased each time it passes through, and it is heated by a high temperature flame. Actually, the mixed gas immediately before being discharged from the fourth divided flow passage 16a of the fourth divided pipe 16 is
The temperature is 850 to 1300 ° C. and the pressure is 0.5 to
It becomes 7.5 MPa. The upper end of the water pipe 11 is connected to gas utilization equipment such as a generator, a gas turbine engine used in a ship or the like, a machine tool for cutting or welding metal, a boiler device or the like. The high-temperature, high-pressure mixed gas obtained by the generator is supplied to such a gas utilization facility and used.

The above operation will be described below. Now, when using the generator as shown in FIG. 1, first, the water is passed through the flow passage 12 of the water pipe 11 by a water supply pump (not shown).
Is pressed in from below. Then, the brown gas is jetted from the nozzle 26 of the heating burner 21 toward the water pipe 11 and ignited. Then, the flame injected from the nozzle 26 heats the outer peripheral surfaces of the first to third divided pipes 13 to 15 forming the water pipe 11, and this heat is applied to the first to third divided pipes 13 to 15.
Is conducted from the outer peripheral surface to the inner peripheral surface to heat the water in the first to third divided flow paths 13a to 15a.

At this time, since the combustion heat of the flame generated by the combustion of the brown gas is very high, the water flowing through the flow path 12 causes a steam explosion at least in part due to the rapid heating that greatly exceeds the boiling point of the water. It expands rapidly and decomposes into hydrogen and oxygen gas. In this state, the pressure of the mixed gas composed of hydrogen and oxygen gas is 1 to 3 MPa.
After that, while pressure-injecting water into the flow channel 12, the pressure generated by generating the mixed gas causes each divided flow channel 13 to flow.
The mixed gas of a to 15a is pushed up toward the fourth split pipe 16.

At this time, the mixed gas is the fourth divided flow path 16
The pressure can be increased by passing through each of the divided flow paths 13a to 15a before reaching a. Then, the mixed gas is further heated while the pressure is increased, so that the temperature thereof is 850 to 1300 ° C. and the pressure is 0.5.
Increased to ~ 7.5 MPa. Then, the high-temperature and high-pressure mixed gas discharged from the fourth divided passage 16a is supplied to the gas utilization equipment and used for a predetermined purpose.

The effects exhibited by the first embodiment will be described below. -According to the generator of the first embodiment, the heating burner 2
Brown gas is used as the fuel of No. 1 and the combustion heat of the flame generated by the combustion of this brown gas becomes extremely high temperature as compared with the combustion heat of the flame generated by the combustion of fossil fuel of the conventional example. For this reason, water is decomposed into hydrogen and oxygen in a short time, and a mixed gas of hydrogen gas and oxygen gas is generated. Therefore, it is not necessary to transfer the combustion heat of the flame of Brown gas for a long time, and the total length of the water pipe 11 is Can be shortened. Therefore, this generator can obtain a mixed gas of hydrogen gas and oxygen gas with a simple structure, and can reduce the size of the entire device.

According to the generator of the first embodiment,
The water pipe 11 is formed in a straight pipe shape, and a plurality of pairs of heating burners 21 are provided so as to face each other with the water pipe 11 interposed therebetween. Therefore, the combustion heat of the flame of Brown gas can be transferred to the entire outer peripheral surface of the water pipe 11.

Further, the water pipe 11 is the first split pipe 13,
The second divided pipe 14, the third divided pipe 15, and the fourth divided pipe 16 are formed by connecting a total of four pipes, and each divided pipe 13 to
The inner diameter of 16 is set to be smaller as it is arranged on the upper end side. As a result, the pressure of the mixed gas generated from the water is increased as the mixed gas proceeds from the lower side to the upper side in the water pipe 11, and the high-pressure mixed gas can be easily obtained. In addition, by providing the check valve 17 at the lower end of the water pipe 11, it is possible to prevent the water from flowing backward as the pressure of the mixed gas is increased in each of the divided pipes 13 to 16.

The nozzle 26 of the heating burner 21
Is attached to the burner body 22 in a threaded relationship, and is thus configured to be removable. For this reason, the nozzle 26 can be replaced, the diameter of the gas injection port 26a can be changed quickly, and the heating power of the brown gas can be easily adjusted.

The water pipe 11 is arranged so as to extend in the vertical direction, and the pressure of the mixed gas increases in each of the divided pipes 13 to 16, so that the water is pushed to a position below the water pipe 11 and stays there. Is configured. Therefore, it is possible to prevent water from being mixed with the mixed gas discharged from the upper end of the water pipe 11.

In the heating burner, the interior of the burner body 22 is partitioned by the partition wall 23 into a gas storage chamber 24 and a cooling chamber 25. Brown gas is supplied to the gas storage chamber 24 and the cooling chamber 25 is supplied with the gas. It is configured to supply water and cool the burner body 22. When the water drained from the cooling chamber 25 is configured to be supplied to the water pipe 11, the preheated water can be supplied to the water pipe 11 and the thermal efficiency can be improved.

In addition, the amount of water maintained in the water pipe 11 is small, and by heating this with the combustion heat of the brown gas at a high temperature, the mixed gas is actually obtained after the water is supplied. It is possible to shorten the time until the start-up, and to make the generator start up quickly.
