Description:

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to power generation, and more particularly to a water power generator that uses water as a raw element, which is abundant and environmental friendly, to produce vapor as an environment, renewable and economical power source.

2. Description of Related Arts

For decades, power has been generated by driving turbines with steam. The reason that turbines are driven by steam is that water is clean and low in viscosity, such that mechanical parts of the turbines can be kept clean and easily maintained, such that turbines have longer life spans, and produce electricity more efficiently. The most common steam generation to produce power is by heating water with the burning of coal to form steam, which is then used for driving turbines to generate electricity.

Originally, this power generation method was relatively cheap when coal was abundant. However, the demand of coal and other sources of fossil fuel have rocketed ever since, due to economical and industrial development of the human race. As a result, after all these years of coal mining and oil drilling, the reserve of such fossil fuel is down to an alarming level, such that many experts kept warning us that the supplies of fossil fuels will run out in less than half a century's time.

Scientists are therefore working very hard on the research of other sources of energy, especially renewable sources for human use.

Abundance is not the only problem encountered by power generation by the burning of fossil fuels. As known, we are experiencing an environmental problem named global warming, which is caused by the emission of green house gases such as chlorofluorocarbons (CFCs), carbon dioxide (CO2), methane (CH4) and nitrogen oxides (NOx), sulfur oxides (SOx), and even dioxin due to the excess burning of fossil fuels. The mining and extraction process of such fossil fuels are also dangerous and pollutes the environment.

Impacts of the rising of temperature caused by global warming include the raising of sea level, changing of precipitation and other local climate conditions. Regional climate are also affected such that forests, crop yields, and water supplies are altered. Global warming also affects human and animal health, and many ecosystems. Over time, deserts are expected to expand into existing rangelands, and features of much greenery throughout the word will be permanently altered. Furthermore, the emission of green house depleted the thickness of the ozone layer, causing a lot of health problems with living beings on Earth.

It is therefore the mission for most environmental scientists to find sources of energy to generate electricity with the problems of abundance and emissions eliminated. Many sources of renewable energy have been identified, including solar energy, geothermal energy, nuclear energy, wind energy and hydroelectric energy. However such sources have draw backs.

Even though the energy obtained from the sun is renewable, its intensity, however, is not strong enough. Also, solar energy is not reliable since it is not a continuous supply. There would be no solar power in dark. Furthermore, it has to be collected, stored and converted to electrical energy by means of solar panels, which are expensive and land consuming. The cost effectiveness and reliability of the utilization of solar energy is therefore low.

Geothermal energy is the drawing of underground heat energy provided by the core of the Earth, by means of heat pumps. As the heat extracted is usually not very high, it is usually used directly for heating and cooling purposes. Very seldom will they be used for boiling water into steam to drive turbines to produce electricity. It not only fails to provide a solution for electricity generation purposes, but also causes a certain degree of destruction of the natural environment due to the fact that we must dig and drill to the underground reserves before we can enjoy the heat energy provided by the core of the Earth.

Nuclear energy is, indeed, a very stable renewable source of energy. The quality of the energy provided is also very reassuring. However, the potential danger of the use of nuclear energy outruns all its benefits. The reason is that nuclear energy is the controlled use of the chain reaction of radioactive substances. The system has to be very well controlled and maintained due to the chain reaction characteristic of such radioactive substances. The result of a tiny upset to the system or malfunction is devastating, as evidenced by the accident in the Chernobyl nuclear power plant in 1986, which caused immediate death to many and left many others with the suffering of leukemia.

Same as solar energy, the cost effectiveness and the reliability of wind energy is relatively low. In order to make use of wind energy, large, expensive and space consuming wind mills must be erected in open area. And the energy supply can never be accurately estimated or guaranteed since it depends solely on the strength and period of the blowing of wind.

Hydroelectric energy makes use of the natural flowing movement of water from a higher place to a lower place. The kinetic energy of water converted from potential energy is used to drive turbines for producing electrical energy. And yet, since dams have to be built across rivers, lakes and oceans, the cost is high and the natural appearance of such places will nevertheless be destroyed.

As a result, a better form of renewable energy is demanded to provide the human race with a renewable and reliable power source that would have least harmful effect to the environment and health of all beings on Earth.

These and other objectives, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1A is a flow chart illustrating a process of power generation according to the a preferred embodiment of the present invention.

FIG. 1B is a flow chart illustrating the substeps of dissociating water to form hydrogen gas and oxygen gas according to the above preferred embodiment.

FIG. 2 is a perspective view of a chimneyless boiler according to the above preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1A and 2 of the drawings, a process of power generation according to a preferred embodiment of the present invention is illustrated, wherein the process comprises the following steps:

(a) Dissociate a water W to form a hydrogen gas and an oxygen gas.

(b) Deliver the hydrogen gas and the oxygen gas to a combustion chamber 31 of a chimneyless boiler 3, wherein the hydrogen gas instantaneously combusts with the oxygen gas in the combustion chamber 31 to produce a blazing flame in the combustion chamber 31.

(c) Heat a liquid L flowing into a boiling chamber 32 of the boiler 3 by the blazing flame in the combustion chamber 31 to produce a vapor V outputted from the boiling chamber 32.

The vapor V outputted from the boiling chamber 32 can be used as power source to drive a power generating device 40, as shown in FIG. 2, such as a turbine to produce electricity or an engine to generate mechanical power.

Practically, although the liquid L in this process can be any liquid, it is preferred to be water due to its low viscosity and its nature of clean, abundant and easy to obtain.

In the step (b), the blazing flame is produced when the hydrogen gas and the oxygen gas produced by the dissociation of water 10 are guided to the combustion chamber 31 of the boiler 3 respectively, due to the chemical properties of hydrogen and oxygen. In the combustion chamber 31, the hydrogen gas instantaneously combusts with the oxygen gas, giving out a large amount of heat energy, and water or water vapor under the high temperature.

In the step (c), the blazing flame produced by the instantaneous combustion of the hydrogen gas with the oxygen gas is then used to heat up a flow of water guided into the boiling chamber 32 of the boiler 3 for boiling, wherein the boiling chamber 32 is in thermal-conduction with the combustion chamber 31. Due to the high temperature of the heat produced by the combustion of hydrogen gas with oxygen gas, the water for boiling in the boiling chamber 32 of the boiler 3 will be heated up above its boiling point, changing its state to the vapor V, i.e. water steam.

The steam V produced will then be guided out of the boiling chamber 32 of the boiler 3 and used for driving the power generating device 40, such as a turbine to generate electricity or an engine to generate mechanical power.

The hydrogen gas and oxygen gas used for heat generation by combustion came from the dissociation of water by an electrolysis process. In the step (a) of dissociating water to form the hydrogen gas and the oxygen gas, it further comprises the substeps of (a-1) providing a predetermined amount of water 10 for dissociation in a water dissociation pool 11, (a-2) adding a predetermined amount of catalyst into the water dissociation pool 11, (a-3) disposing a pair of electrical conductors 12, 13 into the water 10 for dissociation in the water dissociation pool 11, and (a-4) connecting the pair of electrical conductors 12, 13 to an electric power source 14, such that a closed electrical circuit is formed.

One of the pair of electrical conductors 12, 13 is connected to a positive terminal of the power source 14; the other to a negative terminal of the power source 14, wherein the electrical conductor connected to the positive terminal acts as the anode 13 and that to the negative terminal acts as the cathode 12.

Theoretically, without the presence of the catalyst, upon the completion of the electrical circuit, water molecules, H2O, undergo an electrolysis process, where the H2O molecules dissociates to H+ ions and OH ions. Since the H+ ions are now positively charged, meaning that each H+ ion is short of one electron, they are not physically stable. As a result, they are attracted to the cathode 12, where electrons are provided for them to discharge and neutralize, returning to a stable state. When H+ ions are discharged, hydrogen gas is formed at the cathode 12 and collected by an inverse tubular U-shape hydrogen collector 15 surrounding the cathode 12.

Analogously, since the OH ions are now negatively charged, meaning that each ion has one electron in excess, they are not physically stable. As a result, they are attracted to the anode 13, where the electrons are taken away, such that the OH ions are discharged and neutralized, returning to a stable state. When OH ions are discharged, oxygen gas and water is formed and collected by an inverse tubular U-shape oxygen collector 16 surrounding the anode 13.

Dissociation of H2O molecules is illustrated in the following chemical equation:
H2O(l)⇄H+(aq)+OH(aq)

The discharge and neutralization of H+ ions are illustrated in the following chemical equation:
2H+(aq)+e→H2(g)

The discharge and neutralization of OH ions are illustrated in the following chemical equation:
4OH(aq)+4e→2H2O(l)+O2(g)

However, due to the fact that water molecule is a covalent compound, the dissociation of water molecule is relatively slow. The production of hydrogen gas and oxygen gas is slow, rendering the process not so energy efficient.

In order to enhance the production of hydrogen gas and oxygen gas from water, so as to make use of the abundant, environmental friendly substance as an energy source, in the step (a-2), a catalyst is added into the water 10 in the water dissociation pool 11. By adding the catalyst, the rate of water dissociation is augmented and the catalyst itself is not being consumed.

According to the preferred embodiment of the present invention, the catalyst comprises iodine (I2) and sulfur dioxide (SO2). Iodine (I2) and sulfur dioxide (SO2) will aid the dissociation of water molecules in the following manner by first reacting with the water molecules to form hydrogen iodide (HI) and hydrogen sulphate (H2SO4(aq)). The overall chemical equation of this reaction is as follows:
2I2(g)+2SO2(g)+4H2O(l)→4HI(aq)+2H2SO4(aq)

Then, the hydrogen sulphate (H2SO4(aq)) dissociates to a generated water, sulfur dioxide (SO2) and oxygen gas (O2) is produced at the anode 13. The overall chemical equation of this reaction is as follows:
2H2SO4(aq)2H2O(g)+2SO2(g)+O2(g)

The hydrogen iodide (HI) dissociates into iodine (I2) and hydrogen gas (H2) is produced at the cathode 12. The overall chemical equation of this reaction is as follows:
4HI→2I2(g)+2H2(g)

The ratio between the water for dissociation, the iodine (I2) and the sulfur dioxide (SO2) may vary, but is best to be 2:1:1 by mole.

The oxygen gas produced by this water dissociation process is at a temperature as high as 800° C. The hydrogen gas produced by this water dissociation process is at a temperature as high as 400° C.

According to this preferred embodiment of the present invention, an electrical circuit with a voltage of 25V and a current of 4 A is sufficient to start up the entire process, such that energy consumption is minimized and energy efficiency of the entire system maximized.

The hydrogen gas and oxygen gas are then guided and delivered to the combustion chamber 31 of the boiler 3 for the process of power generation by means of combustion.

Since the iodine and sulfur dioxide are only for aiding the dissociation of water molecules and will be generated upon the completion of the dissociation of water to form the hydrogen gas and the oxygen gas, the iodine and the sulfur dioxide are recycled and added into the water 10 in the water dissociation pool 11 again. The generated water is also returned to the water dissociation pool 11 again.

The instantaneous combustion of hydrogen gas with oxygen gas produces the high temperature blazing flame at about 3000° C., which is much higher than the around 1000° C. produced by conventional coal burning process.

The combustion of the hydrogen gas with the oxygen gas is illustrated in the following chemical equation:
2H2(g)+O2(g)→2H2O(g)+energy

The energy here is given out as the flame at about 3000° C., which is used for the heating of water in the boiling chamber 32 of the boiling 3. The water, upon being heated by the flame produced turns into water steam V. The water steam V is then used for driving the power generating device 40 such as the turbine to generate electricity or the engine to generate mechanical power.

According to the preferred embodiment of the present invention, the turbine can be any existing turbines for the purpose of electricity generation. After going through electricity generation in the turbines, the steam V is condensed back to form a condensed water, wherein the condensed water is then recycled back into the boiling chamber 32 of the boiler 3.

The combustion process between oxygen gas and hydrogen gas produces no environmental harmful by-products. In fact, the only product of the combustion process is the team V. As oppose to conventional coal burning heat generation process, which requires the purging of waste gases including carbon dioxide and other harmful by-products, due to the presence of impurities in coal, such as NOx, SOx, CH4, energy lost due to purging of waste gases is minimal. As a result, the energy efficiency of the present combustion process is much better than conventional coal burning combustion process.

It can be easily seen that, by recycling the condensed water from the effluent of the turbine, and the recycling of iodine, sulfur dioxide and generated water back into the dissociation tank, the utility cost of this entire power generation process is minimized. Together with the maximized energy efficiency, this process can achieve its goal of providing a clean, renewable, energy efficient and environmental friendly energy source.

Since there is no gas storage required by this power generation process, the total amounts of hydrogen gas and oxygen gas produced by the water dissociation step (a) are fully used by the flame producing step (b). As a result, the combustion between the hydrogen gas and the oxygen gas can easily be controlled by simply controlling the voltage and current of the electrical circuit used in the step (a) of dissociating water, which in turns controls the production of the hydrogen gas and the oxygen gas.

Referring to FIG. 2 of the drawings, the system of power generation according to the preferred embodiment of the present invention comprises the water dissociation pool 11, the electrical conductor (cathode) 12, the electrical conductor (anode) 13, the electric power source 14, the hydrogen collector 15, the oxygen collector 16, and the boiler 3. The boiler 3 comprises the boiler body 30, the combustion chamber 31 and the boiling chamber 32, wherein boiling chamber has a liquid inlet 301 and a vapor outlet 302 provided on the boiler body 30 and the combustion chamber 31 has a reacting agent input 21.

The combustion chamber 31 is a space defined and surrounded by the boiler body and the boiling chamber 32 in the boiling body 30 is formed around the combustion chamber 31 in a thermal-conduction manner with respect to the combustion chamber 31. The liquid inlet 301 connects to the boiling chamber 32 of the boiler body 30, wherein the liquid inlet 301 guides a liquid for boiling into the boiling chamber 32. The vapor outlet 302 connects to the boiling chamber 32 of the boiler body 30, wherein the vapor outlet 302 guides a vapor produced in the boiling chamber 32 out of the boiling chamber 31.

The reacting agent input 21 guides the reacting agent into the combustion chamber 31, such that the reacting agent combusts in the combustion chamber 31 of the boiler 3.

According to the preferred embodiment of the present invention, this boiler 3 is for the combustion process of oxygen gas and hydrogen gas to heat up the water until the water is heated to form a high temperature steam for driving a power generating device 40 such as a turbine or an engine, wherein the oxygen gas and hydrogen gas are high temperature gases produced by the water dissociation process. The reacting agent therefore comprises oxygen gas and hydrogen gas. The liquid to be guided into the boiling chamber 32 is therefore water.

In order to separately guide the oxygen gas and the hydrogen gas into the combustion chamber 31 of the boiler body 30, the reacting agent input 21 comprises two reacting agent inlets 211 for guiding the hydrogen gas and the oxygen gas into the combustion chamber 31 respectively.

When the hydrogen gas and the oxygen gas are guided into the combustion chamber 31 through the reacting agent inlet 21, the hydrogen gas and the oxygen gas instantaneously combust into a blazing flame. Since the combustion chamber 31 and the boiling chamber 32 are arranged in a thermal conduction manner between each other, the liquid inside the boiling chamber 32 is therefore heated by the blazing flame produced by the combustion of hydrogen gas and the oxygen gas in the combustion chamber 31.

Since the liquid to be heated up in the boiling chamber 32 is water, upon being heated, the water changes its physical state to steam V. No chemical reactions, dissociations or associations of elements are involved and no by-products are produced through the boiling process of the step (c). The boiler 3 therefore does not require a purge stream for the release of by-products. As can be seen, energy lost due to the formation and purging of by-products is minimized. Furthermore, by having no purge stream, the steam V produced in the boiling chamber 32 will only leave the boiling chamber 32 through the vapor outlet 302, such that no energy is lost due to the lost of steam through the purge stream, should there be a purge stream. As a result, the heat produced by the combustion of reacting agent in the combustion chamber 31 will be totally utilized for the heating of the water flowing into the boiling chamber 32 to form steam, such that an energy efficient system is provided.

According to this preferred embodiment of the present invention, in order to withstand the heat produced by the blazing flame and the hot steam V, as well as acidic impurities in water, a combustion chamber wall 311 of the combustion chamber 31 and a boiling chamber wall 321 of the boiling chamber 32 are coated with porcelain enamel respectively.

It will thus be seen that the objects of the present invention have been fully and effectively accomplished. It embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
