Description

technical field [0001] The invention relates to the technical field of new energy power generation, in particular to a solar thermal power generation and biomass energy complementary power generation system. Background technique [0002] Electricity production plays an increasingly important role in modern production and life. For a century, the electric power industry has been heavily dependent on fossil fuels, causing the electric power industry to be the main source of serious environmental pollutants such as carbon dioxide and sulfur dioxide. At the same time, with the depletion of fossil fuels, the cost and difficulty of mining will increase. The development of new energy, reducing dependence on fossil fuels, and using cleaner energy are the inevitable choices of human beings. [0003] Solar energy is the most abundant renewable energy resource in the world. It is a clean and non-polluting energy source. Its development and utilization are recognized as an important pa...
