Biomass coupling fused salt energy storage power generation system
PendingCN114198730ASolve insufficient power supplyPromote digestionHeat storage plantsMachines/enginesBiomass boilerProcess engineering
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.
