Description

The present invention relates to a power plant and a power generation method.

Technological improvement related to power plants is recognized as one of the issues in ensuring the sustainability of the global environment. And one of the most important items in the technical improvement is resource management for energy creation.

Resource management in a power plant refers to the procurement, management and disposal of resources that are the source of the thermal energy supplied to the turbine. Resources in modern society refer to fossil fuels, including coal, oil and natural gas, and nuclear fuels, including uranium and plutonium. In recent years, proposals have been made to use natural energy including solar energy and wind energy as alternative resources.

A power plant based on fossil fuels can be said to be an unstable power source from an environmental or economic point of view because fossil fuels are a depleting resource. In addition, fossil fuels are not suitable for ensuring the sustainability of the global environment because by-products including exhaust gas caused by combustion adversely affect the global environment.

In nuclear fuel-based power plants, the heat generated by the fission reaction is the power source for turbine generators. Nuclear fuel has a high energy density and is easy to store, and since it can be reused as a resource fuel by reprocessing spent fuel, electric energy based on nuclear fuel is positioned as quasi-domestic energy with low resource dependence. (Non-Patent Document 1).

Power plants based on renewable energy can reduce the cost of procuring resources because renewable energy is a semi-permanent resource. However, since the absolute amount of resources is affected by uncertain meteorological phenomena and the energy density is smaller than that of fossil fuels and nuclear fuels, the power plant has a problem of lacking stability in the operation of the power grid. Has (Non-Patent Document 2).

So far, attempts have been made to convert resources in power plants to non-fossil fuels including nuclear fuel for the purpose of improving the energy self-sufficiency rate (Non-Patent Document 1). However, as the shutdown of power plants (nuclear power plants) that use nuclear fuel as resources and the uncertainty in the process of transition to a carbon-free society are attracting attention, the reintroduction to fossil fuels, which can be expected to provide a stable supply of resources. Conversion has been made (Non-Patent Document 3). As a result, the amount of fossil fuel-derived waste has increased, making it difficult to ensure the sustainability of the global environment, and a waste-free (zero waste) system is required. Zero waste means the idea of reducing waste as much as possible.

According to Patent Document 1, a laser light receiving unit installed on the ground that receives laser light generated by being excited by sunlight and a laser light receiving unit installed on the ground that generates energy by using the laser light received by the laser light receiving unit. The power generation device is provided with a concave mirror that reflects the received laser light so as to be focused on a predetermined position and range, and the power generation device is irradiated with the laser light reflected from the concave mirror. By a power generation system comprising a steam generator that generates steam from a heat medium, a steam turbine driven by the steam generated by the steam generator, and a generator driven by the driving force of the steam turbine. Provided is a power generation system capable of efficiently transporting energy obtained by using sunlight as an energy source and using the energy to generate a large-scale power generation (Patent Document 1).

According to Patent Document 2, a solar heat collecting system that collects solar heat to generate saturated steam from water, a power generation system having a saturated steam turbine that can be driven by the saturated steam of the solar heat collecting system, saturated steam of the solar heat collecting system, and It is equipped with a heat storage and heat dissipation system that can introduce water from the power generation system. The heat storage and heat dissipation system includes a heat storage tank formed of a solid heat storage material, and supplies the saturated steam of the solar heat collection system or the heat storage and heat dissipation device that exchanges heat with the water of the power generation system, and the saturated steam of the solar heat collection system to the heat storage and heat dissipation device. First steam supply pipe, water supply pipe that supplies water from the power generation system to the heat storage radiator, steam water separator that separates the gas-liquid two-phase fluid generated by heat exchange with the heat storage radiator into saturated steam and saturated water, separation Provided is a solar thermal power generation system including a second steam supply pipe for supplying the saturated steam to the saturated steam turbine (Patent Document 2).

However, since the radiant intensity of natural sunlight on the ground depends on the global environment including the weather, it is not possible to stably secure the radiant intensity required for the operation of a power plant based on heat generation by condensing light. It's not easy.

In recent years, research on an artificial sun (solar simulator) consisting of multiple light sources has been promoted. Non-Patent Document 4 reports a research that achieves a radiant intensity of 7.5 kW by condensing synchrotron radiation emitted from 18 synchrotron radiation modules into a minute region having a diameter of 5 cm. Non-Patent Documents 5 and 6 describe a report on an artificial sun consisting of 149 xenon lamps. Non-Patent Document 6 reports an example of achieving a radiant intensity of 280 kW. In view of Non-Patent Documents 4, 5 and 6, artificial sun can be mentioned as a resource candidate in a power plant.

According to Patent Document 3, nuclear fuel rods, fission reaction control rods, and radioactive components of nuclear power plants will be wiped out, and all facilities will be utilized to convert to solar power generation. Instead of the nuclear fuel rod, pass the heat-resistant heating rod from the lower water area of the furnace to the upper center, tightly seal the circumference of the heat-resistant heating rod with a heat-resistant member at the upper end of the furnace, and the tip of the heat-resistant heating rod protruding from the furnace. Surround the part with a heat-resistant inner wall mirror box, and make the tip of the uppermost part conical and deploy it exposed. A focal point that collects solar heat is directly focused on the top tip of this heat-resistant heating rod to heat the water in the furnace to generate steam, which turns a steam turbine and rotates a generator to generate electricity (Patent Documents). 3). For this reason, the technological trend of diverting existing power plants to convert to clean energy is increasing.

It should be noted that artificial sun and solar simulators can suppress the generation of waste, which is a problem in the use of fossil fuels and nuclear fuels. Therefore, the realization of zero-waste energy creation is expected by utilizing the artificial sun.

The present invention has been made in view of the above circumstances, and the realization of a power plant capable of reducing the waste generated by the generation of electric power energy is an issue to be solved.

With such a configuration, the present invention can realize a power plant capable of suppressing the generation of waste due to the combustion of fossil fuel or the fission reaction of nuclear fuel. Further, since the present invention is not power generation based on natural energy, it has a technical effect that stability as a power source can be ensured.
