Abstract

The invention provides a thermoelectric decoupling efficient biomass power generation system and method. The system comprises a biomass boiler, a fused salt preheater, a dryer, a high-temperature fused salt tank, a low-temperature fused salt tank, a first fused salt pump, a second fused salt pump, a steam generator, a steam turbine, a steam turbine generator and a condenser. According to the thermoelectric decoupling efficient biomass power generation system and method, a set of fused salt heat storage system is additionally arranged for a biomass power station, the heat production process of a biomass boiler and the power generation process of a steam turbine are decoupled, and the power generation power of the steam turbine is adjusted through the change of the supply amount of fused salt. Particularly, by increasing the capacity of the fused salt storage tank, the load adjusting capacity of the small biomass generator set can be further improved.
