Solar energy-gas complementary generating device and method

Abstract

The invention discloses a solar energy-gas complementary generating device and a generating method, which belongs to the solar thermal generating field. The device comprises a heat absorber, an auxiliary heating burner, and a Stirling engine. The solar energy-gas complementary generating device is characterized in that the solar energy absorbing rate of the heat absorber can be ensured while the solar energy is used; the burning can be steadily implemented while the gas is used for the auxiliary heating so as to ensure the continuity of generation; or the solar heat absorber and the gas are used at the same time, so that the heating tube in the inner part of the heat absorber can absorb the heat produced at burning while receiving the solar energy, and the reliability of the generating system can be improved while the solar energy is insufficient. The solar energy-gas complementary generating device provided by the invention further has the advantages of high utilization rate, impact structure and reliable operation, can not only suitable for the improvement of structure performance of the current disc type solar Stirling thermal generating system, but also provide continuous and steady high-quality electricity for the disc type solar Stirling thermal generating system.

Description

technical field [0001] The invention relates to a solar-gas complementary power generation device and method, belonging to the field of solar thermal power generation. Background technique [0002] The dish solar Stirling thermal power generation system focuses and reflects sunlight to the heating surface of the Stirling machine. The working medium inside the Stirling machine is heated to a high temperature and high pressure state to ensure the high efficiency of the dish Stirling thermal power generation system. run. However, due to the randomness and instability of solar energy, the dish solar Stirling system cannot continuously and stably provide high-quality electric energy, and the use of solar-gas complementary power generation devices to maintain the stability of power generation is one way. This approach can also solve the problem of continuous and stable power generation without changing the structure of the heat absorber of the original system. [0003] The utili...
