摘要： The present application discloses a method and an apparatus for solar power generation through gas volumetric heat absorption based on characteristic absorption spectrum. A radiation energy conversion device absorbs concentrated solar radiation and converts radiation energy into thermal energy; the thermal energy is transferred to the other side of the radiation energy conversion device and then is converted into radiation energy; and the energy is transferred in a receiver cavity. The working gas from the outlet of a recuperator flows into the receiver cavity and absorbs the radiation energy. The heated working gas with high temperature flows into a turbine, doing shaft work through expansion. The expanded working gas flows through the recuperator to exchange heat. The working gas flows into a cooler, a compressor and the recuperator in sequence, and then flows into a receiver cavity to be heated volumetrically, completing a thermal power cycle.

摘要： A radiation thermal absorber based on characteristic absorption spectrum, a Stirling engine and an operation method thereof. The radiation thermal absorber allows working gas in the Stirling engine to absorb radiation heat quickly, and help the Stirling engine adopt assistant heating to ensure steady operation when solar power is not enough. The radiation thermal absorber includes a heater base, a radiation energy conversion device, heating tubes, a combustion chamber and valves of the heating tubes. The radiation energy conversion device converts the solar energy into radiation energy near a characteristic absorption peak of the working gas, and the working gas absorbs the radiation directly in depth.
