Description

TITLE

Design of a portable stove fueled using hydrogen gas obtained from electrolysis performed using solar energy.

FIELD OF THE INVENTION AND USE OF INVENTION [0001] This invention relates to the field of chemical engineering and Electronics Engineering more particularly, a design of a renewable gas stove which is fueled using hydrogen gas obtained using electrolysis of water which is powered using solar energy. This invention also relates to a method and apparatus that produces a combustible gas and may store the combustible gas. The electrolysis process is powered using electric power which is obtained using the solar panels equipped near the stove based system.

[0002] Here, a hydrogen stove is designed which is capable of being controlled remotely and is continuously monitored so as to function efficiently. The apparatus is having water as fuel by using an electrolyzing component to produce the combustible gas from water. The electrolyzing component is powered using solar panel which is equipped near the system and to increase the efficiency of the system the perovskite solar cells are used to obtain the solar rays. The system is continuously monitored and the heat of the stove is managed so as maintain safety of the system and the surrounding.

PRIOR ART AND PROBLEM TO BE SOLVED [0003] At present, due to the increasing depletion of the earth's resources, gradually cannot meet the demand for resources, resulting in the possibility of application of new energy greatly increased, new energy sources, including solar, hydro, biomass, hydrogen. In the field of cooking various types of apparatus are known. Known cooking apparatus utilize

2020100010 03 Jan 2020 [0004] [0005] [0006] liquefied petroleum gas (LPG) that is stored in a tank as fuel. When LPG tanks went empty after a certain amount of usage, delivery of a filled-up tank is necessary to replace the empty tank. This exercise has been proven impractical yet inevitable since no other convenient way of refilling the tanks are known. Another disadvantage of using LPG as burner fuel is safety since leaks can happen in the LPG line and since the LPG is a heavy gas and highly combustible, the gas leak may settle in the environment and may explode with open flame.

This invention provides with a system designed with the purpose to resolve the above-mentioned where a hydrogen stove, comprising a solar generator, water electrolysis apparatus and the work surface is designed. The electrolysis setup in the system receives the water combustion product and regenerates it to gaseous hydrogen. Means also are provided for storing the hydrogen from the electrolysis periods of excess electrical energy for supply. The stove is made smart so as to self-stop if an overheating is sensed and if the hydrogen fuel consistency is also incorrect so as to maintain safety and security.

THE OBJECTIVES OF THE INVENTION:

Various types of cooking apparatus are known. These include barbeques, ovens, and gas and electric cook tops. Barbeques utilize charcoal, propane (that is stored in a tank) or natural gas as a heating source. The gas or charcoal is combusted below the cooking surface and the heat from the combustion is utilized to cook the food. The advent of the energy shortage has increased the importance of non-fossil energy sources such as solar radiation for cooking.

It has already been proposed where, electric stove is used so as to reduce the use of LGP but the problem still holds that in the production of

2020100010 03 Jan 2020 [0007] [0008] [0009] [0010] [0011] electricity still consumes conventional form of energy which still creates the problem due to the excessive use of fossil fuels. Secondly the electric stove cannot be used to cook all forms of food as the efficiency obtained from the fire-based cooking is not achieved with electricity.

The principle objective of the invention is a portable hydrogen stove which can be controlled remotely using internet of things so as to increase the efficiency of the stove and to control the operation of it as it is functioning using a highly combustible gas and it is powered using renewable source of energy.

Another objective of the invention is the hydrogen fuel which is used as a fuel to stove is obtained from the electrolysis of water where the hydrogen gas is obtained and stored for providing the required fuel for the stove.

The further objective of the invention is that for the electrolysis system to work the power is provided using solar panels which are equipped near the system and the panels are equipped with perovskites solar cells so as to obtain maximum efficiency. The heat energy helps to function the electrolysis system to produce hydrogen fuel.

The further objective of the invention is that the stove has been designed with the mechanism to be controlled remotely using any computing device and to indicate error if observed. The stove can self-stop if an overheating is sensed and if the hydrogen fuel consistency is also incorrect which helps to keep the system and surrounding safe.

SUMMARY OF THE INVENTION

At present, the commonly used gas stoves to gas or natural gas, the problem is likely to cause environmental pollution, and the use of unsafe,

2020100010 03 Jan 2020 high energy consumption. The gas stoves use either natural gas or liquified petroleum gas (LPG) or liquified natural gas (LNG). These although burn with low relative pollutant gas emissions, they still are considered potentially hazardous and have to be carefully handled. The people using stoves while cooking food, have to rely on the gas valve to control and make adjustments and to control the size of the fire. The problem is brought about in this way when you need to frequently adjust the intensity of the fire, the operation is troublesome, time-consuming, but no adjustment will make the cooking ineffective, resulting in a lot of heat is wasted and in addition with all the advances in gas knobs, LPG or LNG based cooking still remains highly inefficient in terms of energy transfer and utilization. So here in this invention a hydrogen stove is designed where water is provided as fuel where the electrolysis of water is performed so as to obtain the hydrogen gas. To make the system highly efficient and to make it functional using renewable source of energy. This is made possible using solar panels where the energy forms the same is used for the functioning of the electrolysis process. The system is equipped with sensors so as to obtain the data and to keep a track of its functioning. The remote controlling helps to operate the system using computing device so as to receive all the details regarding the system’s working and measures to take in case of any accident.

The present invention is about a design and working of a hydrogen fueled stove which is made smart and can be controlled remotely and the working and the operation of the system is made using renewable source of energy so as to make it ecological and economical along with its obtaining high efficiency in the working of the stove.

The control apparatus comprising a gas stove, router and a user terminal apparatus, the control apparatus of the gas stove is provided with a controller, connected to said controller for detecting the temperature. The Internet of Things (loT) devices may be equipped with various types of sensors to collect information about themselves and their surroundings and provide the collected information from the stove system.

A hydrogen stove, comprising a solar generator, the water electrolysis device and the work surface. The stove has an electrolysis system wherein the water from integrated combustor/heat exchanger/condenser is channeled, as at, to a water management system which may include

2020100010 03 Jan 2020 accumulator means. Water from the water management system is supplied to electrolysis component by an appropriate pump means.

[0020] Electrolyzing component regenerates the water to gaseous hydrogen and oxygen which can be stored, as in storage tanks, respectively. These components of combustion then can be controlled, as by the use of valves, for supplying the components to integrated combustor/heat exchanger/condenser, as indicated by lines, respectively, for purposes of combustion.

[0021] Electrolyzed water which forms gases of hydrogen and oxygen, also known as Hydroxy or Oxy-hydrogen enriched gas, which is a full reformation of water from its non-combustible liquid state to a highly combustible and implosive diatomic gas state through electrolysis by applying electricity on a clean tap or distilled water with a small amount of electrolyte. Electrolyzing system which extracts the hydrogen and the. oxygen from water coming from a water source. The water source is stored in a water reservoir. The electrolyzing component is powered by a DC electricity. The water flowing to the electrolyzing component flows through and from a main scrubber unit wherein the primary condensation and recirculation takes place.

[0022] The hydrogen and oxygen gases then pass through a series of conditioning chambers wherein compressed ambient air is injected into the system. The ambient air is supplied from an air pump and is stored in an air tank 16. The ambient air mixes in a proportional ratio with the scrubbed hydrogen and oxygen gases. The compressed air also manages and conditions the flow of the combustible gases upstream to a burner.

[0023] All the elements making up the system such as the electrolyzing component, reservoir, main scrubber, conditioning chambers, air pump, air tank and power control module are lodged in a single cabinet-type housing

2020100010 03 Jan 2020 module except for the burner which is disposed at the top of the housing module. The cabinet housing allows the present cooker to be easily transported from one location to another.

[0024] The water reservoir has an extended filler port which is disposed outside the housing module to facilitate easy water refilling to the system. The cooking apparatus further includes a circuit breaker disposed inside the power control module 18 to provide electrical safety from abnormal conditions such as overcurrent and overvoltage. Pressure sensor and pressure switch module are provided to cut-off system flow when very large pressure develop.

[0025] The hydrogen and oxygen may be collected from the headspace of the electrolyzing component and conveyed through the same passage to manifold 36. Alternately, the hydrogen and oxygen may be separately collected from the electrolyzing component and provided to ports via separate passages. Accordingly, the hydrogen and oxygen may be mixed at ports. It is also possible to provide only hydrogen gas to the ports and to bum the hydrogen with atmospheric oxygen. The advantage of an alternate embodiment that uses a hydrogen storage media is that the hydrogen produced can be withdrawn from the hydrogen storage media and burned at a rate that is greater than the rate of energy delivery to the electrolyzing component to create the hydrogen gas originally.

[0026] When a sufficient amount of gas has been produced to produce a constant flame, a valve may open to permit the gas to be provided to a burner. The ignition member is operating thereby resulting in the gas automatically being ignited when it flows to the burner. Alternately, the circuit may include a timer, pressure sensor, flow sensor or the like that causes the ignition member to be actuated when gas starts flowing to the burner like in the case of a sparking ignition member. If the ignition member is a heated wire, then the timer, pressure sensor, flow sensor or the like may

2020100010 03 Jan 2020 cause the ignition wire to commence heating sufficiently in advance of the gas flowing to the burner such that the ignition wire is at temperature when the gas reaches the burner. It will be appreciated that the single control may be a start button that is pushed and held down by a consumer until a flame is produced like the lamp light indicating that the button may be released or a light extinguished indicating that the button may be released. Alternately, the start button may merely be pressed and the circuit configured to maintain the operation of the electrolyzing component and the ignition member during the startup sequence.

[0027] The burner may be any burner known in the art. In accordance with another aspect of this invention is the burner which comprises one or more manifolds which incorporate a series of ports through which a combustible fuel (gas, liquid or solid) is delivered to create flames which will provide heat, or additional heat, to cook the food and to enhance convective air currents. The flames can be used to cook the food, or the electric heating element can be used to cook the food 16, or a combination thereof can be used to cook the food.

[0028] The power source which is attached to the electrolyze for its working is an alternating current source, then an AC to DC converter, such as four diodes or bridge rectifier, is employed to convert the alternating input current into the direct current required by the electrolyzing component.

[0029] The system is completely controlled and monitored using a sensor assembly which is capable of receiving ate floor data and to take action in case any unwanted activity is identified. The electrolysis system can be turned on and off based on the command from the user or with the help of pre-programmed data fed to the system. This helps to make the system smart. In addition to the same the flame detection module detects the flame and the ignition pulse module is programmed to be closed so as to stop the ignition in case within few seconds the flame is not detected, In this case

2020100010 03 Jan 2020 of ignition failure and immediate stop of processing the flow control module stops the supply to the gas stove, and the fault information module transmits failure information to the user. In case If the ignition is successful, the temperature detecting block continuously detect the temperature of cooking food, and temperature controller calculates the processing according to the customized information to run the program and the control module 6 controls the flow rate adjusting the flame size of fire even to close the flame, when the stove is turned off. It can be reignited by opening the flow control module and the pulse ignition module.

[0030] To function the electrolysis system the system is powered using the electric energy generated from the solar panel assembly which is created using perovskite solar cells to make it efficient and compact. To reduce shading and to increase the packing factor, in some embodiments, the cells are connected in a shingled pattern. The performance of the solar panel can be further improved by applying maximum power point tracking technology and bypass protection at the cell or cell-group level.

[0031] In the panel the perovskite single solar cell, comprises: a photoanode negative electrode, the electron collection layer, a light absorbing layer, a hole transporting layer, and the catalytic layer as a positive electrode a pair of electrodes, an anode and a light layer of conductive layer by the transport of electrons and holes to the outer electrode circuit. Here in the system the solar panel that includes a plurality of solar cells connected in series in such a way that solar cells in each row are connected in series, and the rows are also connected to each other in series. The rightmost solar cell of the first row is serially connected to the rightmost solar cell of the second row. The serial connection zigzags through the entire panel until the last solar cell is connected.

[0032] The integral micro-inverter device is configured on the back or underside of the solar panel. Micro-inverter device has high conversion

2020100010 03 Jan 2020 efficiency, but no moving parts to wear out or maintain. Moreover, the micro-inverter device exhibits very low internal temperature rise and long lifetime. So here when sunlight shines on them, each solar panel generates DC electrical power, which is converted into grid-compliant AC electrical power by its respective micro-inverter device. Because each solar panel produces power independently of the others, the failure of one solar panel does not adversely affect power output of the remaining solar panels. Moreover, the present invention is capable of operating at a maximum power point tracking thereby increasing energy output 5-25%. The solar panel is provided with the flexibility of back tracking so as to obtain maximum solar efficiency. So as per the rays of the sun the panel shift to the appropriate position so as to reduce shade and to obtain maximum rays. The electric energy obtained is fed to the electrolysis system so as to function it to obtain hydrogen fuel for the functioning of the stove.

[0033] The user is capable of controlling the system remotely and to preprogram the functioning. The system can be made so compact that it can be made potable to so as to make it operable in indoors and outdoors. So here when a user need stove for cooking food, the device is opened, electrical power generated by the solar generator 4, this part of the electric energy is fed to the electrolysis system to obtain fuel for the stove by using the electrolysis of water to produce hydrogen gas which is stored in the collection bottle, When the ignition of the burner is switched on the hydrogen is released in a controlled manner and the burner is lit and when the purpose or the scheduled time is over the stove is turned off.

[0034] While there has been illustrated and described embodiments of the present invention, those of ordinary skill in the art, to be understood that various changes may be made to these embodiments without departing from the principles and spirit of the present invention, modifications, substitutions and modifications, the scope of the invention being indicated by the appended claims and their equivalents.
