Title:
METHOD AND APPARATUS FOR SOLAR POWER GENERATION THROUGH GAS HEAT ABSORPTION BASED ON CHARACTERISTIC ABSORPTION SPECTRUM
Document Type and Number:
Japanese Patent JP2018025382
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for solar power generation of high efficiency and low costs with a heat absorber of a simple structure, by converting solar energy into radiation energy near a characteristic absorption peak of a working gas by using a light energy conversion device, and significantly reducing a heat absorption surface area by making a working medium absorb the radiation energy directly in all directions.SOLUTION: One side of a light energy conversion device absorbs concentrated solar light and converts the same into thermal energy, the thermal energy is transferred to the other side of the light energy conversion device, then is converted into radiation energy near a characteristic absorption peak of a working gas, and radiated into a heat absorber cavity to exchange heat. The heated working gas with high temperature flows into a regenerator to exchange heat, then flows into a solar heat absorber, and absorbs the radiation energy radiated into the heat absorber cavity from the light energy conversion device in all directions, thus a temperature is quickly raised, the heated working gas is expanded to work, and a heat generation cycle is executed.SELECTED DRAWING: Figure 1
