Prior Art

In the present day, pressurized steam is used in many areas of industry.

The areas of use of the pressurized steam can be listed as such:

1 - Electricity Generating Steam T urbines

2- Steam heating systems,

3- Chemical processes,

4- Food Industry (in the production of fruit juice, macaroni, cheese and dairy products

production) and also sterilization.

1 1 - Wood processing (wood carving)

The production of the subject pressurized steam is provided in steam boilers or steam generators. The first takes place by the superheated gasses generated by the burning of fossil- based fuels passing through the smoke tubes by waiting for the water inside the boiler body to heat up and boil and pass on to the vapor phase. in principle, the steam generators are units which produce vapor without storing the same and send it to the system, working with considerably low volumes of water. The working principle is based on the water which is to be passed on to vapor phase is heated with fossil-based fuels from outside the steel tube, which is straight or helically bended, and flooded with water.

In the steam generation methods used in the prior art, it is observed that the water is heated indirectly and thus, there are thermal losses and therefore; decreased productivity.

The productivity of these systems used in the known state of the art depends on the fuel used. They operate with a productivity of 60% with the solid fuelled boilers, 70% with liquid fuelled boilers and 85% with gas fuelled boilers.

One of the most important problems in the known state of the art is the flue gasses generated as waste as a result of the fossil fuels burning. The subject harmful gasses exhausted from the flue affect the environment and human health adversely.

Conversion of water to vapor takes a long time with the boiler or generator method in the known state of the art.

The heat formation in the boiler or generator methods in the known state of the art increase the labour for burning fossil.

The use of fossil fuels for the heat formation in the known state of the art increases the production costs.

Several applications have been encountered related to the mentioned steam production method as a result of the research of the literature. One of these is the patent application number

TR2018/041 1 1 titled“Low Pressure Direct Steam Generator”. In the abstract of the invention classification class A47J 31/54, the statement appears that:“The invention is related to a low pressure direct steam generator which uses low pressure steam, which can be installed at any location where heat is needed since it is not pressurized, which is suitable for independent operation and in which the energy loss and the risk of fault-maintenance is lowered thanks to the short energy transfer lines.”

In the above-mentioned application, the heat formation occurs by means of the burning gasses heating the water. The same may be given as an example to the above-mentioned disadvantages on the issues of time and productivity.

Consequently; improvements are made in parallel to the advancing technology in steam production methods and thus, there is a need for new applications which will eliminate the above-mentioned disadvantages and deliver a solution to the present systems. Purpose of the Invention

The invention is related to steam production methods which are developed for solving the mentioned disadvantages and which bring some additional advantages as distinct from the applications used in the present art.

The purpose of the invention is to provide steam production by eliminating the fossil-based fuel use. By this means, the waste of gasses which harm the environment and the people is prevented.

Another purpose of the invention is to heat up the water present in the reactor body with plasma arc directly and provide steam production within seconds and increase steam production productivity by this means.

Another purpose of the invention is to provide for the water to be converted to vapor within seconds by generating plasma arc by means of tungsten electrodes.

Another purpose of the invention is to eliminate the need for fossil fuels by providing the heat necessary for converting the water to vapor using electricity. This reduces both the cost and the labour.

In order to realise the above purposes; a steam production process in which the pressurized steam used in industry is produced within seconds is developed. The electrolytic water which will be used as the raw material of the subject vapor is formed in the water tank. The electrolytic water prepared in the water tank by being located within the mentioned water tank is brought to the desired temperature with the heater. The transfer and conversion of the electrolytic water prepared and heated in the mentioned water tank to vapor is performed in the reactor body. Conveying of the electrolytic water heated in the mentioned water tank to the reactor body is provided by the hot water delivery tube. There are electrodes which are placed within the mentioned reactor body and which provide for generating the plasma arc after being fed with current and provide the vaporization of the electrolytic water by this means. On the upper part of the mentioned reactor body, the steam exit where the outlet of the steam that is produced inside is performed is formed. The ejection of the steam produced in the reactor body when it reaches the desired pressure is provided by the proportional steam exit valve by being installed on the mentioned steam exit. The current fed to the mentioned electrodes is supplied from the power source. The temperature of the vapor formed within the reactor body, pressure value and production amount are controlled by the control panel.

Figure 1 is the two-dimensional front view of the steam generating reactor(1 ). The water purifying device (10) provides for the mains water to be purified and turned into distilled water for supplying distilled water necessary for the electrolytic water (S).

The water tank (20) is the tank where the distilled water, which means the electrolytic water (S) exiting from the water purifying device (10) is stored. In addition, it provides for the water to be pressed into the reactor body (40).

The heater (21 ) having the sufficient capacity for heating the electrolytic water (S) to approximately 50- 70 C is present in the water tank (20). The hater is the generally used electric resistance.

The water pump (30) is used in order to press the electrolytic water (S) heated in the water tank (20) into the reactor body (40) at a certain pressure.

The reactor body (40) is the structure in which the vapor (B) is produced and pressurized with the electro-chemical reaction the plasma arc has created. It is produced from stainless steel material. The electrodes (41 ), the safety valve (42), the steam flowmeter (43), the proportional steam exit valve (44), the sight glass (45), the pressure sensor (46), the temperature sensor (47) and the steam exit (48) are present on the reactor body (40). Figure 2 shows the cross-sectional view of the reactor body (40).

The mention electrodes (41 ) are used in order to transfer the current coming from the power source (50) to the electrolytic solution. Here, tungsten electrode is used as electrode (41 ). Tungsten electrodescan carry a heavier current compared to other electrode types.

Safety valve (42) provides limiting the pressure in the reactor body (40).

Steam flowmeter (43) provides measuring the amount and dryness fraction of the produced vapor (B). In the subject system, the immersion steam flowmeter is used, known as vortex steam flowmeter in the market.

The proportional steam exit valve (44) is the element used to control the pressure and flow of the vapor (B).

The sight glass (45) provides the visual monitoring of the plasma arc inside the reactor body (40). Since high temperatures will be reached within the reactor body (40), heat-resistant borosilicate glassis used.

Pressure sensor (46) transfers the pressure data in the reactor body (40) to the control panel (80).

The temperature sensor (47) transfers the temperature data in the reactor body (40) to the control panel (80).

The steam exit (48) is the part located on the upper part of the reactor body (40), where the outlet of the vapor (B) to outside of the body is performed. The above mentioned proportional steam exit valve (44) is installed on the steam exit (48). The power source (50) produces electrochemical reaction and then, the voltage and current necessary for the generating of the plasma arc. The plasma arc is the high energy generated after current is given to the tungsten electrodes (41 ). The mentioned plasma arc provides for the quick vaporization of the electrolytic water (S) at a certain temperature.

The insulating material (60) prevents the conveying of the voltage and current coming to the electrodes (41 ) from the power source (50) to the reactor body (40). The insulating material (60) is produced from teflon material.

The level meter (70) is the element which sends the water level data in the reactor body (40) to the control panel(70).

The control panel (80) is the panel where the production of the vapor (B) as full automatic and the turning of the system on and off is controlled.

The mounting principle;

Steam generating reactor (1 ) is installed on a flat surface. The mounting principle to be described from this point forward will be described over figure 1. Figure 1 is a side-by-side the two- dimensional view of the steam generating reactor (1 ) that has been installed.

The water purifying device (10), the water tank (20), the water pump (30), the reactor body (40), the power source (50) and the control panel (80) which are mentioned in the structure principle and which are the general parts of the structure are positioned on a flat surface and interconnected.

The water purifying device (10) and the water tank (20) are interconnected with the distilled water delivery tube (1 1 ).

The heater (21 ) is positioned in the water tank (20). By this means, it is provided that the distilled water within the water tank (20) is heated within the 50-70 C degree range.

The hot water delivery tube (22) is installed at the lower part of the water tank (20). The mentioned hot water delivery tube (22) is connected to the lower part of the reactor body (40). The water pump (30) is contacted at the middle part of the mentioned hot water delivery tube (22) and the conveyance of the hot water in the water tank (20) to the reactor body (40) is provided.

The sight glass (45) is formed on the surface and the middle part of the reactor body (40). As mentioned in the structure principle, the live sighting of the plasma arc from outside is provided.

Again, in the inner part of the reactor body (40), the electrodes (41 ) having anode and cathode poles are placed reciprocally. These two electrodes are connected. The power source cable (51 ) is connected to the electrodes (41 ). The power source cable (51 ) is string between the electrodes (41 ) and the power source (50) and energy transmission to the electrodes (41 ) is provided. The electrodes (41 ) have a mechanically up and down moving structure. After water is filled into the reactor body (40), it is levelled down and the start of the reaction is provided.lt can move up and down according to the water level. The power source (50) is positioned on the ground next to the reactor body (40).

While the power source cable (51 ) passes the outer structure of the reactor body (40), in order to prevent the same from contacting the surface, insulating material (60) is used. The insulating material (60) prevents the energy being transmitted to the reactor body (40) and prevents working accidents.

The temperature sensor (47) is placed on the upper part of the reactor body (40). The temperature sensing part of the temperature sensor (47) stays inside while the adjusted part stays outside.

Again, the pressure sensor (46) is placed on the upper part of the reactor body (40). The part to measure the vapor (B) pressure level stays inside while the part which shows the pressure level stays outside.

In order for the pressure inside the reactor body (40) to be limited, the safety valve (42) is placed on the topmost part. The safety valve (42) is connected to the inner part of the reactor body (40) and it is provided that the pressure is stabilised in case of excess heavy pressure.

The steam exit (48) takes place on the topmost and middle part of the reactor body (40). The proportional steam exit valve (44) is installed at the steam exit (48). The steam flowmeter (43) is placed at the end of the proportional steam exit valve (44). The steam flowmeter (43) measures the produced vapor (B) amount and the dryness fraction of the vapor (B).

The level meter (70), which has an open connection with the inside, is placed at the side of the reactor body (40) in order to measure the liquid amount inside. The water pressurized within fills into the level meter (70) and transmits the inside water level data to the control panel (80).

Finally, the control panel (80) is positioned on the same ground. Reading and adjustment of all the updated data is provided by making its connection with the above-mentioned elements.

Figure 3 is the perspective view of the steam generating reactor (1 ) whose mounting is complete.

The working principle;

The distilled water prepared in the water purifying device (10) is taken into the water tank (20). 0.5 and 0.7 molar Sodium Bicarbonate (NaFIC03) or 0.2 and 0.6 molar Potassium Carbonate (K2C03) solutionis prepared in the water tank (20).

The solution prepared in the water tank (20) is heated up to approximately 50-70 C degree temperature with the heater (21 ) in order to lower the electrical resistance and pressed into the reactor body (40) produced from stainless steel with the water pump (30). With the top level limit signal coming from the level meter (70), the procedure of pressing water into the reactor body (40) is stopped. The insulating material (60) produced from teflon prevents the voltage and current coming from the power source (50) to the electrodes (41 ) to be conveyed to the reactor body (40). The electrodes (41 ) are lowered into the aqueous solution.

The electro chemical reaction starts with the application of DC voltage increasing from 0 to 500 volts to the electrodes (41 ) which are connected to the positive and negative poles of the power source (50). With the combustion of the plasma arc, the heat within the reactor body (40) increases constantly. With the plasma arc heat being brought to the maximum, the water within the reactor body (40) starts to boil and the vapor (B) starts to accumulate in the top part of the reactor body (40). From this moment forward, the temperature and pressure values in the vapor (B) charts written by the thermodynamic laws form in the reactor body (40). The pressure sensor (46) and the temperature sensor (47) transfer the measurement data to the control panel (80) momentarily. According to the area of use, when the vapor (B) is brought to the desired pressure and temperature, the proportional steam exit valve (44) is opened, the vapor (B) is allowed to exit and the amount and dryness fraction of the produced vapor (B) is monitored from the steam flowmeter (43) and thecontrol panel (80). The safety valve (42) is mounted on the reactor body (40) to limit the pressure.

As vapor (B) is produced, water is pumped into the reactor body (40) from the water tank (20) with the help of the water pump (30) to replace the decreased water amount and vapor (B) is produced anew and thus, the cycle continues. The sight glass (45) attached to the reactor body (40) provides the plasma arc to be visually monitored from outside. All the control, adjustment and recording procedures are controlled by the operator over the control panel (80) and the production of vapor (B) is continues fully automatic.

The volumetric capacity and geometrical dimensions of the reactor body (40) and the power of the power source (50) depend on the amount, pressure and temperature of the vapor (B) to be produced.

The Steam Production Method;

• The distilled water is produced in the water purifying device (10).

• The distilled water produced in the water purifying device (10) is conveyed to the water tank

(20) from the distilled water delivery tube (1 1 ) and the electrolytic water(S) solution is prepared there.

• The electrolytic water(S) solution prepared in the water tank (20) is heated with the heater

(21 ). • The electrolytic water (S) solution brought to the desired temperature is pressed into the reactor body (40) with the help of the water pump (30) until the top limit signal is received from the level meter (70).

• Electrodes (41 ) are lowered into the electrolytic water (S).

• Voltage and current is applied to the electrodes (41 ) from the power source (50). The insulating material (60) provides the insulation.

• The vapor (B) pressure and temperature within the reactor body (40) is controlled from the control panel (80). The safety-purpose safety valve (42) limits the reactor pressure.

• When the desired steam pressure is reached within the reactor body (40), the proportional steam exit valve (44) is opened and the steam exit is allowed.

• The amount, dryness fraction of the produced vapor (B) and many data are transferred to the control panel (80) from the steam flowmeter (43).
