The aforementioned circulation system (L2) is connected to the pipes 101b and 101c respectively connected to the first and second pressure vessels 120 and 110, as shown in FIG. 3, and both pipes ( A third electromagnetic valve V3 controlled by a controller is provided between 101b) 101c and the circulation system L2. Accordingly, the water in the first pressure vessel 120 and/or the second pressure vessel 110 may be discharged to the circulation system L2 according to the opening direction of the third solenoid valve V3 described above.

The check valve referred to in the present invention is a manual valve through which water flows in only one direction, and the aforementioned electromagnetic valves are electromagnetic valves that open and close a plurality of outlet-side conduits (three-way valves) by a controller.

The above-described combustion chamber 104 is coupled to the exhaust pipe 103 (FIGS. 1 and 2) in communication with the combustion chamber and the above-mentioned first and second pressure vessels 120 and 110 are protected by a jacket 101. have. The jacket 101 is provided with a fire brick (not shown in the drawing) or a heat insulating material on the inner wall thereof.

As shown in FIG. 3 , the first and second pressure vessels 120 and 110 described above are connected through a connecting pipe (not shown) having a fourth electromagnetic valve V4 controlled by a controller.

In addition, the first and second pressure vessels 120 and 110 are combined with a steam discharge system (L3) for discharging the internal steam. The steam discharge system (L3) is coupled to the fifth electromagnetic valve (V5) controlled by the controller. Therefore, steam may be discharged along the steam discharge system L3 from either side or both sides of both pressure vessels 120 and 110 according to the opening direction of the above-described fifth solenoid valve V5.

In addition, both the pressure vessels 120 and 110 described above are coupled with a manual safety valve ( FIG. 1 , not indicated by reference numerals) that is automatically opened by the overpressure when overpressure occurs in the container.

The water supply system L1 is provided with a second solenoid valve V2 as shown in FIG. 3 . Accordingly, the second electromagnetic valve V2 may be controlled by the control of the controller so that water is simultaneously supplied into the heat exchanger 121 and the second pressure vessel 110 or water is supplied to any one place.

Hereinafter, in controlling the steam rapid production apparatus, it is assumed that there is no water in the first and second pressure vessels 120 and 110 .

First, when the operation start button (meaning start in FIG. 4) is turned on (On), the operation of the rapid steam production apparatus 100 is started.

The water level in the first pressure vessel 120 is sensed by the lowest water level sensor among the water level sensors S, and when the water level sensor senses, the controller sends the raw water W through the water supply system L1 to While controlling the first solenoid valve (V1) and the second solenoid valve (V2) to be introduced into the 121 and the second pressure vessel 110, the feed water pump M is controlled to be driven (On), and at the same time, the Control (On) so that the sixth solenoid valve (V6, Fig. 3) is opened for air discharge (a, Fig. 4).

In this way, the raw water (W, FIG. 2 ) is supplied into the first pressure vessel 120 and the second pressure vessel 110 until the uppermost water level sensor is sensed along the water supply system L1 .

In this case, since the capacity of the first pressure vessel 120 is small compared to the capacity of the second pressure vessel 110 as described above, the first pressure vessel 120 reaches the set water level relatively faster. At this time, when the uppermost water level sensor of the first pressure vessel 120 is sensed, the controller controls (Off) so that the pipeline of the sixth electromagnetic valve (V6) for air discharge is closed (b, FIG. 4), while supplying water with the burner 102 (b, FIG. 4) The pump M is controlled (On) and the third electromagnetic valve V3 is controlled (On) so that the pipe 101c connected to the first pressure vessel 120 is connected to the circulation system L2.

In this way, the water in the first pressure vessel 120 is continuously circulated along the circulation system (L2) and the water supply system (L1) until the temperature reaches the set range while maintaining the set water level, and the heat exchanger (121) heated rapidly through Steam generated in this process is accumulated on the water surface in the first pressure vessel (120).

When the water temperature of the above-described first pressure vessel 120 reaches a set temperature range (sensed by a temperature sensor), the controller controls (Off) so that the feed water pump (M) and the burner 102 are stopped, and the fifth electromagnetic valve ( V5) is controlled (On) (d, FIG. 4). Therefore, the steam in the first pressure vessel 120 is discharged along the discharge system (L3).

As the above-described fifth solenoid valve V5 is opened, steam is discharged through the discharge system L3, and in this process, when the water level in the first pressure vessel 120 falls, the controller controls the water level sensor ), the feed water pump M and the burner 102 are controlled (On) until the set water level (sensed by the highest water level sensor) and the temperature are reached ( FIG. 4 ).

As above, while steam is generated in the first pressure vessel 120, water is supplied to the second pressure vessel 110 and heated at the same time.

At this time, the controller controls (On) (c, FIG. 4) so that the first electromagnetic valve (V1) is opened until water is supplied to the set water level in the second pressure vessel (110), thereby forming the circulation system (L2) and the water supply system ( L1) is connected and raw water (W) is supplied along the water supply system (L1).

Accordingly, the second pressure vessel 110 may continuously produce steam while the steam is generated in the first pressure vessel 120 .

As described above, in a situation in which steam is generated in the first pressure vessel 120 , the controller controls so that steam is also generated in the second pressure vessel 110 .

That is, the controller controls the second pressure vessel 110 by the control method described above for the first pressure vessel 120 .

Therefore, when the temperature of the second pressure vessel 110 reaches the set temperature range, the controller controls the conduit of the fourth electromagnetic valve V4 to be opened so that the water stored in both containers 110 and 120 is mixed with each other (e) , Figure 4), and at the same time control (On) the third electromagnetic valve (V3) so that the pipes (101b, 101c) connected to both containers (110, 120) communicate with the circulation system (L1), raw water (W) is introduced into the water supply system (L1), and also controls (On) the pipeline of the first electromagnetic valve (V1) so that the water supply system (L1) and the circulation system (L2) communicate with each other, and in both containers (110) and (120) The conduit of the fifth solenoid valve V5 is controlled (On) so that the generated steam is discharged along the discharge system L3.

According to this control, the steam generated in both containers 120 and 110 is discharged through the steam discharge system (L3) at the same time, the discharged steam does not flow back by the check valves (C4, C5).

When the water level in the second pressure vessel 120 falls below a set range by the steam discharged along the discharge system L3, the controller controls the water pump M to be driven (On) and supplies water to the set height. When is made, the burner 102 is controlled to operate (On).

In this state, the controller controls the water supply pump (M) to circulate water along the circulation system (L2) and the water supply system (L1) until the temperature of both containers (120, 110) is within the set temperature range (On) )do.

Conversely, when the water temperature in both pressure vessels falls below the set temperature range in a state in which steam is not consumed, the controller controls (On) the above-described feed water pump M and the burner 102 so that the water temperature is within the set temperature range.

As described above, according to the present invention, steam can be rapidly produced first through the first steam generator, and a large amount of steam can be produced by the second steam generator while the produced steam is serviced according to its purpose.

In the above, a preferred embodiment has been described with reference to the accompanying drawings with respect to the steam rapid manufacturing apparatus and the control method thereof according to the present invention, but this is only described for illustrative purposes to help the understanding of the present invention.
