Description

The present invention relates to a Stirling engine generator generator that generates electricity using a heating element, superheated steam, and molten salt as heat sources.

Today, where local production for local consumption of energy, establishment of independent power sources, and transformation of energy production into an energy circulation society are required, Stirling engine generators and generators have come to be used for waste heat utilization.

Stirling engine generators are used for waste heat from waste incinerators, waste heat from boilers, power generation from combustion of petroleum products, power generation from combustion of biomass fuel, waste heat from combustion of hydrocarbons, and direct use of combustion. The Stirling engine generator is used for power generation by.

The Stirling engine generator is a temperature difference generator, and the exhaust gas heat and combustion airflow used above are absorbed by the heat absorbing part of the Stirling engine generator to generate electricity. However, due to changes in the exhaust temperature, the exhaust gas is absorbed by the heat absorbing part. When passing through, soot adheres due to factors such as gas component, solid component, tar component, etc., and the heat absorption efficiency decreases, and the power generation efficiency decreases, so that the heat absorption portion needs to be cleaned frequently.

If incomplete combustion occurs due to improper adjustment of the air ratio used in the incinerator or combustion furnace, or due to the difference in fuel, soot adheres more and the amount of power generation decreases due to the decrease in heat absorption efficiency, and the heat absorption part deteriorates faster. Maintenance of the Stirling engine generator requires desorption work and cleaning work, which increases the cost. The present invention provides the Stirling engine heat-absorbing part with high-temperature energy generated by a heating element, heated steam, or molten salt that does not contain hydrocarbon-derived components, thereby avoiding contamination of the Stirling engine generator heat-absorbing part and achieving stable power generation without maintenance. It is to provide a Stirling engine power generator that can.

The Stirling engine is a heat engine that realizes the Carnot cycle with the theoretical limit efficiency among cycle heat engines, and is the engine with the highest power generation efficiency. The Stirling engine generator is an α type consisting of two power pistons, a β type in which the displacer and power piston are arranged in the same cylinder, a γ type in which the dispressor and power piston are arranged in different cylinders, and a power piston. There is a type of double acting type that utilizes the space on the lower surface, and the α type (Patent No. 6194634) that is currently in practical use has a structure in which a horizontal space is taken and the piston moves left and right. The β type (Patent No. 5388111 and Patent No. 6106102) is a small and easy-to-use Stirling engine generator in which the piston moves vertically. In the present invention, since a high-temperature energy generator using a heating element or heated steam is attached to the heat absorbing portion of the Stirling engine generator, any Stirling engine generator having a heat absorbing portion can be attached to generate electricity. it can.

Technology that uses a Stirling engine generator to generate electricity by using waste heat from combustion of hydrocarbon-derived products and by using combustion has been put into practical use. For example, in Patent Documents 1 to 3, Stirling engine generators are installed in the waste heat path of existing incinerators and boilers, and the waste heat is used to generate electricity to purchase fuel used in incinerators and boilers. We are trying to reduce power generation. However, in Patent Documents 1 to 3, the sterling engine generator uses a combustion gas (exhaust gas) whose temperature has been reduced from about 300 ° C. to 400 ° C. on the waste heat path that has been used for incineration and steam generation. It generates electricity and supplements the electricity and fuel of auxiliary equipment used in incinerators and boilers, and does not generate surplus electricity. In addition, waste heat from fossil fuels as a waste heat source and waste heat from waste incinerators frequently cause soot and dirt in the heat absorbing part of the Stirling engine generator.

All of the above-mentioned prior art documents are techniques for adding a Stirling engine generator to an existing incinerator and an existing boiler to reduce the fuel used in the existing incinerator and the existing boiler and the purchased electric power. This is a technology that installs a Stirling engine generator in the waste heat path of an existing incinerator and an existing boiler and uses the waste heat to generate electricity. The combustion heat of the existing incinerator and the existing boiler is used to incinerate the target object or generate steam, and the combustion heat is generated by the sterling engine with the exhaust gas that has been cooled in the middle of the waste heat path that has been used in the target process, and the existing incineration It is described in the specification that surplus power is never generated, which is the power of auxiliary machinery used for processing the furnace and the existing boiler, and the Sterling power generation power for supplementing the fuel.

The power generation device by the Sterling engine generator of the present invention is mounted on the heat absorbing part of the Sterling engine generator. The power generation chamber stores the heat absorbing part of the Sterling engine in a heat-resistant container and supplies the high temperature by the high-temperature heating element to the heat absorbing part. The heat absorbing part of the Sterling engine generator is stored in the container and the power generation room, and the heat absorbing part of the power generation room that supplies the high temperature energy from the superheated steam to the heat absorbing part is installed in the heat absorbing container, and the heat absorbing part is covered with the molten salt storage container to melt. The salt is heated by a high temperature stream and the high temperature energy of the molten salt is supplied to the heat absorbing part. Therefore, the endothermic part of the Stirling engine generator provides a Stirling power generation device that does not require maintenance because the heat absorbing part is not contaminated by high temperature energy that is not sooted by a heating element, superheated steam, and molten salt.

An object of the present invention is that the heat-absorbing portion of a Stirling engine generator that generates electricity from waste heat burned by a hydrocarbon-derived product is contaminated by the exhaust gas of a hydrocarbon-derived component, and the power generation efficiency is lowered. There is a problem that the maintenance cost is high. Further, there is a problem that a stable amount of power generation cannot be obtained because the temperature is not stable due to the waste heat burned by the hydrocarbon-derived product.
Stirling engine power generation by installing a heat-resistant container in the power generation room that gives stable high-temperature energy from a heating element or heated steam that does not contain hydrocarbon-derived components and high-temperature heat storage energy of molten salt to the heat-absorbing part of the Stirling engine generator. The purpose is to provide a Stirling engine power generator that does not require maintenance while avoiding dirt on the heat absorbing part of the machine and maintaining a stable amount of power generation. By installing a plurality of devices of the present invention, it is possible to establish the self-sustaining energy of the business establishment and to supply electric power to the area.

In the present invention, the heat absorbing part of the Sterling engine generator is provided with a heat generating chamber heat-resistant container that applies high-temperature energy from a heating element, heated steam, and molten salt to generate electricity, so that maintenance of the heat absorbing part is not required. It relates to a Sterling engine power generator that can generate power without lowering the power generation efficiency.

The Sterling engine generator heat-absorbing part is stored in the power generation room heat-absorbing container, and a heating element is applied so as to cover the heat-absorbing part, and the heating element is generated. It can be generated by a Sterling engine generator with high temperature energy of about 1000 degrees. A heating element is a heating element that generates heat with extremely weak electricity.

By using this heating element, the heat absorbing portion of the Stirling generator is not contaminated, and the contamination does not cause a decrease in power generation efficiency. In addition, maintenance of the heat absorbing part becomes unnecessary. The heating element that gives high temperature energy to the heat absorbing part can supply stable high temperature to the heat absorbing part by using a heating element that generates high temperature with low energy such as a self-propagating heating element, a multilayer film heating element, and can continuously generate power. it can. By supplying electricity to the heating element with photovoltaic power generation such as renewable energy, the Stirling engine generator can operate continuously day and night and continue to generate electricity without an external power source. As a heating element, there is generally a heating element that uses a sheathed heater, but there is a problem that a large amount of electric power is used. The amount of heating element power used that generates heat with extremely weak electricity can be less than or equal to the amount of power generated by the Stirling engine. If renewable energy such as sunlight is used as the power of the heating element, day and night power generation can be sustained without inputting purchased power.

By installing a plurality of power generation devices of the present invention, it is possible to install a power plant that can generate power without purchasing electric power, and it is possible to operate a power plant that does not require an independent external power source. A photovoltaic power plant is a power plant of the same type that does not require an external power source, but can generate power only during the daytime, and if the power generation device of the present invention is used, it becomes a power plant that can sustain day and night power generation.

In addition, we will explain how to produce the same effect as a heating element by using heated steam for high-temperature energy. In the present invention, high-temperature energy that does not contain hydrocarbon-derived components is generated in the heat-absorbing part of the Stirling engine generator. By giving high-temperature energy due to the heated steam, dirt on the heat-absorbing part of the Stirling engine generator can be avoided, power generation efficiency does not decrease, and maintenance can be performed. The purpose is to provide an unnecessary Stirling engine power generator.

That is, a heat absorbing part of the Sterling engine generator and a blow port of the generated heated steam are formed in one space inside the heat-resistant container in the power generation chamber, and superheated steam is generated around the saturated steam pipe in one heat-resistant container in the adjacent superheated steam generation chamber. Sterling that gives high heat to the saturated steam pipe with the heating element that rises to about 1000 degrees in an instant to generate heated steam, and gives the high temperature energy of the heated steam to the heat absorbing part in the heat absorbing container of the power generation room to generate electricity. It is an engine power generator.

The heating element for generating saturated steam as superheated steam around the saturated steam tube is to supply stable heated steam to the endothermic part by using a heating element that generates high temperature with low energy such as a self-propagating heating multilayer film heating element. Therefore, it is possible to continuously generate power without maintenance of the heat absorbing part.

Saturated steam for making heated steam can be obtained by using the steam produced by the steam boiler. Further, in the steam production system of the boiler, by incorporating the power generation device using the superheated steam of the present invention into the boiler system, the power of the boiler system can be supplied, and the hot water whose cooling water has risen in the sterling engine generator is put into the boiler water supply tank. This will reduce boiler fuel. Further, the boiler fuel can be reduced by exchanging heat with the steam that has finished power generation with the heated steam to raise the temperature of the boiler feed water. Furthermore, since most factories are fully equipped with boiler equipment, it is possible to establish an independent power source in the office by installing a plurality of power generation devices of the present invention.

In addition, we will explain how superheated steam generation produces the same effect as a heating element. The present invention generates high-temperature energy that does not contain hydrocarbon-derived components to the heat-absorbing part of the Stirling engine generator. By giving high-temperature energy due to the heated steam, dirt on the heat-absorbing part of the Stirling engine generator can be avoided, power generation efficiency is not reduced, and maintenance is performed. The purpose is to provide an unnecessary Stirling engine power generator. Saturated steam can be the saturated steam used in boiler systems and carbonizers.

That is, a heat absorbing part of the Sterling engine generator, a heated steam inlet, and a heated steam discharge port are formed in one space inside the heat-resistant container of the power generation chamber, and a saturated steam pipe is arranged in the heat-resistant container of the superheated steam generation chamber on the adjacent side. It is a Sterling engine power generator that heats a saturated steam pipe with a burner or a high-temperature airflow from high-temperature waste heat around it to generate heated steam, and is placed in a heat-resistant container in an adjacent power generation room to generate power with high-temperature energy. The fuel cost can be minimized by using a biomass fuel or a dry distillation gas fuel produced by a carbonization device as the burner fuel. Further, by using the high temperature waste heat energy of the combustion furnace boiler that generates high temperature waste heat, valuable energy becomes unnecessary.

An object of the present invention is to apply high-temperature energy free of hydrocarbon-derived components to the heat-absorbing part of the Stirling engine generator by applying high-temperature energy from a burner or heated steam generated by high-temperature waste heat to the heat-absorbing part of the Stirling engine generator. It is to provide a Stirling engine power generation device that can avoid dirt, does not require maintenance of the heat absorbing part, and does not reduce the power generation efficiency.
By installing one or more Stirling engines in this device, it is possible to establish an independent power source for business establishments and supply electric power to the area.

An object of the present invention is to provide the Stirling engine generator heat-absorbing part with high-temperature energy generated by a heating element, generated heated steam, or molten salt that does not contain hydrocarbon-derived components, thereby avoiding contamination of the Stirling engine generator heat-absorbing part, and stable power generation. It is to provide a maintenance-free Stirling engine generator while maintaining the quantity. By installing a plurality of devices of the present invention, it is possible to generate electricity permanently, establish an independent power source for business establishments, and supply electric power to the area.

The power generation device using the Stirling engine generator according to the present invention relates to a Stirling engine generator power generation device that generates power using a heating element, heated steam, and molten salt as heat sources.
This will be described in detail below.

It is a structure. A heating element is applied so as to cover the heat absorbing part in the heat-resistant container, and the high-temperature energy generated by the heating element is applied to the heat absorbing part of the Stirling engine generator to generate electricity.

By using a heating element, the heat absorbing portion of the Stirling generator is not contaminated, the efficiency of the generator is not lowered due to the contamination, and maintenance of the heat absorbing portion is not required. A heating element that gives a high temperature to the endothermic part is a self-propagating heating element, such as a heating element. However, it instantly generates heat of about 1000 degrees. It is also a heating element that can control the heat generation temperature by controlling the electrical energy. Various types of heating elements have been developed, and instead of specifying the heating element, a heating element that instantly reaches a high temperature with extremely small electric energy is used.
By using a heating element that generates heat at a high temperature with low energy, stable high-temperature energy can be supplied to the endothermic part of the Stirling engine to generate electricity permanently. By supplying electricity to the heating element with photovoltaic power such as renewable energy, the heating element power can be turned into self-sustaining power. In addition, when the Sterling engine generator operates and power generation occurs, the surplus power can be used to supply the heating element power, and the Sterling engine generator operates continuously day and night, and power generation can be sustained without the need for an external power source.

By installing a plurality of power generation devices of the present invention, a power plant capable of generating power without an external power source becomes possible, and an independent power plant without a power source becomes possible. Photovoltaic power plants are the same type of non-powered power plants, but they cannot generate electricity at night. If the power generation device of the present invention is used, the power plant can independently supply day and night power. By reducing the power used by the heating element to less than the power generated, it becomes a power plant that can last day and night by supplying self-generated power to the heating element even if there is no solar power generation at night.

In addition, the method associated with the example in the previous section, which produces a power generation effect similar to that of a heating element by using heated steam, will be described. According to the present invention, by giving high-temperature energy containing no hydrocarbon-derived components to the heat-absorbing part of the Stirling engine generator by heating steam using a heating element, it is possible to avoid contamination of the heat-absorbing part of the Stirling engine generator, and the power generation efficiency is lowered. The aim is to provide a maintenance-free Stirling engine generator.

That is, the heat absorbing part of the Sterling engine generator and the heated steam are blown into one space inside the heat-resistant container of the power generation chamber to form a heated steam outlet and a heated steam discharge port, and around the saturated steam pipe provided in the space of the heated steam generation chamber adjacent to one side. A heating element is applied to generate saturated steam into superheated steam, saturated steam is generated into heated steam by the heating element that rises to about 1000 degrees at an instant, and the superheated steam is blown into the heat-resistant container of the power generation room to transfer high-temperature energy to the heat absorbing part.

The heating element for generating saturated steam into superheated steam around the saturated steam tube is a self-propagating heating element, such as a heating element, which is a metal multilayer film in which light metals and transition metal semiconductor elements are laminated and deposited to a nano-thickness. When the electric energy of is given, it instantly generates heat of about 1000 degrees while emitting a flash of light. In addition, it is a heating element that can control the heat generation temperature by controlling a very small amount of electrical energy. Various types of heating elements have been developed, and instead of specifying the heating element, a heating element that instantly reaches a high temperature with extremely small electric energy is used.
Therefore, by supplying stable heated steam to the endothermic unit, it is possible to continuously generate power.

By attaching the device of the present invention to a general boiler system, the boiler system power and the boiler fuel can be reduced. That is, the steam generated by the boiler is collected in the header and transported to a place suitable for each purpose of use. The steam from the header is saturated steam, and this steam is guided to the superheated steam generation part of this device, and a heating element that reaches a high temperature of about 1000 degrees is arranged so as to cover the circumference of the saturated steam pipe in the superheated steam generation chamber. Generates heated steam. The generated superheated steam is guided from the heated steam generation chamber to the adjacent Stirling engine endothermic section, and high-temperature energy is absorbed to generate Stirling engine power generation. The superheated steam that has exchanged heat in the heat absorbing part can reduce the amount of boiler fuel by exchanging heat from the superheated steam outlet installed in the power generation room of the Stirling engine heat absorbing part and putting it in the boiler water supply tank. Further, if the high temperature waste heat of the boiler is guided into the superheated steam generation chamber, it can play the role of a heating element.

The electric power generated by this device in the boiler system can be used for fan electric power, burner electric power, pump electric power, and the like. By raising the water supply temperature with the waste heat of the apparatus of the present invention, the boiler fuel can be reduced and the boiler efficiency can be improved. Further, by attaching the apparatus of the present invention to the boiler including the Stirling engine, it is possible to attach a plurality of units to one boiler, so that not only the boiler system power but also the independent power source of the business establishment can be established.

In addition, a method of generating superheated steam applied to the endothermic part by a burner or a waste heat high temperature airflow will be described. The present invention avoids contamination of the heat absorbing part of the Stirling engine generator by generating high temperature energy that does not contain hydrocarbon-derived components to the heat absorbing part of the Stirling engine generator by generating heated steam with a burner or waste heat high temperature airflow. The purpose is to provide a Stirling engine power generator that does not reduce power generation efficiency and does not require maintenance.

The power generation device using the Stirling engine generator 1 according to the present invention relates to the Stirling engine generator 1 power generation device that generates power using the heating element 4 as a heat source.
This will be described in detail below.

In the present invention, the heat absorbing portion 3 of the Stirling engine generator is covered with a sealed power generation room heat-resistant container 2, the power generation room heat-resistant container 2 is made of metal or metal and castable to a thickness of 2 cm to 10 cm, and the inside of the power generation room heat-resistant container 2 is Stirling. The heat absorbing portion 3 of the engine generator is sealed, and the heat absorbing portion 3 of the Stirling engine generator 1 is located in the outside air portion. The heat absorbing portion 3 is sealed by the heat-resistant container 2 in the power generation chamber, but has a removable structure. A heating element 4 is provided between the power generation room heat absorbing container 2 and the heat absorbing portion 3 so as to cover the Stirling engine heat absorbing portion 3 in the power generation chamber heat absorbing container 2, and the Stirling engine power is generated by the high temperature energy of about 1000 degrees generated by the heating element 4. Machine 1 can generate electricity. The Stirling engine generator 1 outside the heat-resistant container 2 in the power generation chamber pushes down the piston pushed up at a high temperature by the cooling water through which the cooling water passes. The cooling water 1 becomes hot water and can be used for multiple purposes.

By using the heating element 4 generated by electricity supplied from the electricity supply line 5, the heating element 3 does not become dirty due to the endothermic action of the endothermic part 3 of the Sterling generator, which causes a decrease in the efficiency of the generator due to the dirt. There is no need for maintenance of the heat absorbing part. The heating element 4 that gives a high temperature to the heat absorbing part 3 is a self-propagating heating element heating element, etc., and when a very small amount of electrical energy is applied from the outside to a metal multilayer film in which a light metal and a transition metal semiconductor element are laminated and deposited in a nano-thickness, it is approximately. It generates heat of 1000 degrees. Further, the heating element 4 can control the heat generation temperature by controlling a very small amount of electric energy. Various types of heating elements 4 have been developed, and a heating element 4 that instantly reaches a high temperature with extremely small electric energy is used instead of specifying the heating element 4.

The heating element 4 used in the present invention has a heating element having a thickness of 20 to 30 microns in a band shape having a width of about 1 cm, and the heating elements 4 are arranged in a band shape with an interval of about 1 cm. Leave a space of about 2 to 3 cm between the heat absorbing part 3 and the heating element 4. The heating element 4 generates heat at a high temperature of about 1000 degrees with low energy, but the heat energy of the heating element 4 on the heat absorbing part 3 side is absorbed by the heat absorbing part 3, but the heat energy of the opposite part of the heating element 4 is the heat generating chamber heat container. 2 Reflects inside and is absorbed by the heat absorbing portion 3. In order to make the reflected heat efficient, the heat energy of the heating element 4 can be efficiently given to the heat absorbing unit 3 by providing the heat reflecting plate 6 between the heating element 4 and the inside of the heat generating container 2 in the power generation chamber. The electric power used by the heating element 4 is less than the electric power to be generated, and the amount of electric power generated varies depending on the presence or absence of the heat reflector, the position space, and the structure of the power generation heat-resistant container 2.

The Stirling engine generator 1 is provided by each company, and in the above embodiment, it is applied to the heat absorbing portion 3 having a diameter of 20 cm and a length of 10 cm. The heating element can be freely processed, and the interval length is the Stirling engine of each company. The shape is arranged with high efficiency according to the shape of the generator 1 heat absorbing portion 3.

Since the Stirling engine generator 1 has a structure in which the piston is moved by the gas expanded by high heat obtained by the heat absorbing unit 3 and the piston is returned by the cooling water, the cooling water becomes hot water and is discharged. Therefore, hot water can be used for multiple purposes.

By supplying a stable high temperature to the endothermic unit 3 by using the heating element 4, it is possible to generate electricity permanently. The electricity supplied to the heating element 4 can be supplied by photovoltaic power generation such as renewable energy. Further, when the Sterling engine generator 1 operates and power generation occurs, the surplus power can be used to cover the heating element 4 power, and the Sterling engine generator 1 can continuously operate day and night and continue to generate power without the need for an external power source.

By installing a plurality of power generation devices of the present invention, a power plant capable of generating power without purchasing electric power becomes possible, and an independent power plant can be made permanent. A photovoltaic power plant is a non-powered power plant of the same type, but cannot generate power at night. If the power generation device of the present invention is used, it can supply power during the day and night. By reducing the power used by the heating element 4 to less than or equal to the power generated, the power plant can be made permanent by supplying the self-generated power to the heating element 4 even if there is no solar power generation in the nighttime power generation.

The power generation device using the Stirling engine generator 1 according to the present invention relates to the Stirling engine generator 1 power generation device that generates power using the superheated steam generated by the heating element 3 as a heat source.
This will be described in detail below.

It is composed of a heat absorbing container 2 in the power generation chamber and a superheated steam generation chamber 9, and a heat absorbing portion 3 having a diameter of 20 cm and a length of 10 cm and a heated steam outlet 7 are formed in the space inside the heat absorbing container 2 in the power generation chamber. Then, a plurality of saturated steam pipes 8 meandering in the space of the heat-resistant container 9 in the adjacent heated steam generation chamber are heated around the saturated steam pipe 8 with a diameter of about 10 cm and a length of about 30 cm to generate superheated steam. The heating element 4 has a width of 1 cm and is spaced 2 cm apart to provide a spiral space with the saturated steam tube 8. The heating element 4 that rises to about 1000 degrees heats the saturated steam tube 8 to generate heated steam, and high-temperature energy is generated. Is blown into the heat-resistant container 2 of the power generation chamber and applied to the heat absorbing portion 3 of the Sterling engine to generate electricity. The heating element 4 is supplied with electricity from the electricity supply line 5 and overheats. The shape of the saturated steam pipe 8 is not limited because the thermal efficiency is improved by arranging the saturated steam pipes in a meandering manner.

The heating element 4 for generating saturated steam into superheated steam around the saturated steam tube 8 is external to a metal multilayer film in which a light metal and a transition metal semiconductor element are laminated and deposited to a nano-thickness by a self-propagating heat-generating multilayer heating element or the like. When a very small amount of electric energy is given from the body, it generates heat of about 1000 degrees. Further, the heating element 4 can control the heat generation temperature by controlling a very small amount of electric energy. Various types of heating elements 4 have been developed, and the heating element 4 is not specified, but a high-efficiency heating element 4 that instantly reaches about 1000 degrees with extremely small electric energy is used. Therefore, by supplying stable heated steam to the endothermic unit 3, it is possible to generate electricity permanently. Depending on the shape of the endothermic portion 3 of various Stirling engines, the shape-length interval of the heating element 4 that generates superheated steam is an efficient shape.

The heat-resistant container 2 in the power generation chamber and the heat-resistant capacity 9 in the superheated steam generation chamber are covered with metal or metal and a castable thickness of about 2 cm to 10 cm. The heat absorbing portion of the Sterling engine generator 1 is sealed in the heat-resistant container 2 of the power generation room, and the saturated steam pipe 8 derived from the boiler system or the like is arranged in a meandering shape in the heat-resistant container 9 of the heated steam generation room adjacent to the heat-resistant container 2 of the power generation room. The heating elements 4 having a spiral shape covering the saturated steam pipe 8 and having a width of about 1 cm are spirally arranged at intervals of about 3 to 4 m and a space of about 2 to 3 cm, and there is a space between the saturated steam pipe 8 and the heating element 4. It has been subjected. The saturated steam pipe 8 side of the heating element 3 is given high temperature energy of about 1000 degrees, but the opposite side of the heating element 4 is reflected inside the heat insulating container 9 in the heated steam generation chamber and gives high temperature energy to the saturated steam pipe 8. By placing the heat reflector 6 in the space between the inner surface of the heating steam generation chamber heat-resistant container 9 and the heating element 4, the saturated steam tube reflects the high-temperature energy of about 1000 degrees emitted from the heating element 4 on the opposite side of the saturated steam tube 8. The heat efficiency is improved by giving to 8.

The generated heated steam gives high-temperature energy to the Stirling engine heat absorbing portion 3 in the heat-resistant container 2 of the adjacent power generation chamber, and the Stirling engine generator 1 generates electricity. The superheated steam heat exchanged by the heat absorbing unit 3 is discharged from the superheated steam discharge port 10 of the heat-generating container 2 in the power generation room where the heat absorbing unit 3 is located. The discharged superheated steam can be used to raise the temperature of the supply water used in the boiler system to reduce the amount of boiler fuel. Since the cooling water used in the Stirling engine generator 1 rises by about 6 to 10 degrees after power generation, the boiler fuel can be further reduced by putting the heated cooling water into the boiler water supply tank.

By attaching the apparatus of the present invention to a general boiler system, there is an advantage that the boiler system power and the boiler fuel can be reduced. That is, the saturated steam of the boiler is collected in the header and transported to a place suitable for each purpose of use. The steam from the header is saturated steam, and this steam can be guided to the superheated steam generator of this device. Further, the electric power of the heating element can be reduced by inducing the waste heat of the boiler to the heat insulating container 9 of the heated steam generation chamber.

The power generated in the boiler system can be used for fan power, burner power, pump power, etc. Boiler fuel can be reduced by raising the water supply temperature with superheated steam waste heat of the device of the present invention, and if the device of the present invention is attached to a boiler, a boiler system can be obtained by attaching a plurality of the devices to one boiler. Not only the electric power but also the electric power of the business establishment can be covered by the number of installed units.
The attachment of the device of the present invention to the boiler system is an example of applying the device of the present invention.

The power generation device using the Stirling engine generator 1 according to the present invention relates to the Stirling engine generator 1 power generation device that generates power using the superheated steam generated by the burner 12 as a heat source.
This will be described in detail below.

High-temperature energy that does not contain hydrocarbon-derived components is generated in the heat-absorbing part 3 of the Stirling engine generator 1 by the burner 12 to generate high-temperature energy, and the heat-absorbing part 3 is given high-temperature energy to avoid contamination of the Stirling engine generator 1 heat-absorbing part 3. It is to provide a Stirling engine power generator that does not reduce the power generation efficiency and does not require maintenance.

It is composed of a heat-absorbing container 2 in the power generation chamber and a heat-resistant container 9 in the superheated steam generation chamber, and in the space inside the heat-resistant container 2 in the power generation chamber, the heat absorbing portion 3 of the Sterling engine generator 1 has a diameter of 20 cm and a length of 10 cm. And the superheated steam discharge port 10 is formed, and the saturated steam pipe 8 meandering in the space of the heat-resistant container 9 in one of the adjacent heated steam generation chambers is heated with high temperature hot air of about 1000 degrees to generate heated steam. This is a Sterling engine power generator that blows high-temperature energy into the heat-resistant container 2 of the power generation chamber and gives it to the heat absorbing unit 3 of the Sterling engine to generate electricity.

The burner is a burner that burns using a gasified biomass fuel or a dry distillate gas produced by a carbonizer to heat the saturated steam pipe 8 at a high temperature to generate heated steam, and absorb heat in the heat-resistant container 2 of the adjacent power generation chamber. This is a Sterling engine power generator that generates electricity by applying high-temperature superheated steam to part 3. The superheated steam for which the high-temperature superheated steam has completed heat exchange at the endothermic unit 3 is discharged from the superheated steam discharge port 10. The high temperature airflow of the burner 12 of the superheated steam generation chamber heat-resistant container 9 is discharged to the outside from the burner exhaust port 11 provided in the heated steam generation chamber heat-resistant container 9. It is also possible to use the waste heat high temperature airflow of the combustion furnace boiler to generate the heated steam.

The power generation device using the Stirling engine generator 1 according to the present invention relates to the Stirling engine generator 1 power generation device that generates power using molten salt as a heat source.
This will be described in detail below.

The Stirling engine generator 1 heat absorbing section 3 is sealed with the molten salt reservoir 11 in the power generation chamber, and the molten salt reservoir 16 in the power generation chamber is sealed with the heat-resistant container 15 for high-temperature energy containing no hydrocarbon-derived components. The inside of the heat-resistant container 15 is provided with a high-temperature airflow ejection port 13 for blowing the high-temperature airflow induced from the high-temperature airflow inlet 17 into the heat-resistant container 15, and is blown into the heat-resistant container 15. High-temperature energy is stored in the molten salt in the molten salt storage container 16 in the power generation chamber sealed in the heat-resistant container 15, and the high-temperature energy of the molten salt is absorbed by the Stirling engine generator 1 heat-absorbing unit 3 to generate electricity.

The high-temperature airflow blown into the heat-resistant container 15 is discharged from the exhaust port 14 after heat energy is stored in the molten salt in the molten salt reservoir 16 of the power generation chamber. The high-temperature airflow blown into the heat-resistant container 15 has the same effect as long as it is the high-temperature exhaust gas of the combustion furnace, the high-temperature exhaust gas of the boiler, the dry distillate gas burner airflow, the combustion furnace burner airflow, and the high-temperature airflow.

The molten salt of the present invention is an ionic liquid that is solid at room temperature and becomes liquid when heat is applied. It has a large specific heat and is sealed by a power generation chamber molten salt storage container 16 having a molten salt built in the heat absorbing portion 3 of the Sterling engine. It is a Sterling engine generator 1 that generates heat by accumulating heat energy in molten salt in a storage container 16 with a high temperature air stream and supplying high temperature energy to a heat absorbing unit 3. Since molten salt generally releases stored energy by external heat exchange, it always receives heat from the outside and circulates, so a high-temperature pump is required. However, the present invention does not circulate and stores the molten salt in the power generation room. Since the structure is such that heat is applied to the molten salt of the container 16 and the molten salt supplies heat to the heat absorbing portion 3, the molten salt and the heat absorbing portion 3 can be integrated to perform efficient heat exchange, and the heat absorbing portion 3 is also contaminated. Stable power generation can be performed. By using the molten salt heat medium, heat is accumulated in the molten salt, and the change in power generation due to the temperature change of the high temperature airflow blown into the heat-resistant container 15 is eliminated, so that stable power generation can be obtained.
Solar heat energy can also be used as a heat storage method for molten salts.
Further, instead of the molten salt in the molten salt storage container 16 in the power generation chamber, a semiconductor element can be laminated inside the molten salt storage container 16 in the power generation chamber to generate heat by a microwave to generate electricity.
In today's world, where local energy production and local consumption, establishment of independent power sources, and transformation of energy production are required for an energy circulation society, there are renewable energy power generation such as solar power, hydropower, and wind power, but power generation affected by weather changes. Is. The device of the present invention is a small power generation device that can stand on its own without being affected by climate variability. It provides power generation equipment that can be used for various purposes, from small-scale power generation to large-scale power plants with crowds.
