Biomass coupling fused salt energy storage power generation system

Abstract

The embodiment of the invention provides a biomass coupling fused salt energy storage power generation system which comprises a cold fused salt storage tank, a fused salt electric heater, a hot fused salt storage tank, a heat exchanger, a biomass boiler and a conventional island, and the cold fused salt storage tank, the fused salt electric heater, the hot fused salt storage tank and the heat exchanger are connected through pipelines to form a first loop. The heat exchanger is connected with the conventional island through a pipeline to form a second loop, and the first loop and the second loop exchange heat through the heat exchanger; the biomass boiler is connected with the conventional island through a pipeline to form a third loop; and the second loop and the third loop are cooperatively controlled. The problem that a conventional biomass power station is insufficient in power supply when fuel is in shortage is effectively solved, meanwhile, consumption of wind power and photoelectricity in the electricity consumption trough period can be effectively promoted, peak load shifting of a power grid is achieved, and the clean energy utilization level is improved.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a biomass coupled molten salt energy storage power generation system. Background technique [0002] At present, reducing dependence on fossil energy and developing renewable energy has become a common choice for all countries in the world to deal with energy challenges. As a renewable energy power generation method, biomass power generation has the advantages of mature technology and good regulation performance. Biomass power plants use the heat energy obtained by burning biomass fuel in biomass boilers to heat working medium water, generate high (medium) temperature and high pressure steam, enter steam turbines to do work, drive steam turbines to rotate and drive generators to generate electricity. [0003] Among the total operating costs of biomass power plants in my country, fuel costs account for the largest proportion. For biomass power generation projects that us...
