Review on orderly energy utilization of biomass waste
Based on the production,distribution,and utilization status of biomass waste resources in China,this paper analyzes the current situation of high energy consumption and carbon emission during the trans-portation of biomass waste resources utilization,and points out that compared with compression,drying and baking,the low-temperature pyrolysis method has the advantage in terms of the volume reduction and qua-lity improvement of biomass waste.Then the paper demonstrates that the energy consumption and carbon emission in the transportation can be reduced through the volume reduction and quality improvement pre-treatment of biomass waster,and proposes to apply the molten salt energy storage technology with the ad-vantages of strong peak shaving ability,long service life,low cost of scale,and safety and environmental protection,to the low-temperature pyrolysis pre-treatment of biomass waste.The paper conducts compre-hensive analysis of a case study of low-temperature pyrolysis treatment process for biomass waste based on coupled molten salt energy storage,which verifies the feasibility and economy of the process.The results show that due to the consumption of clean energy and the storage and utilization of valley electricity using molten salt energy storage,the energy utilization rate in the process of biomass energy utilization is effec-tively improved,and the annual carbon emission is reduced by 378.49 t CO2eq,with good economic bene-fits.The transform from disordered biomass waste to orderly energy utilization is achieved,which is of great significance to the dual-carbon strategy.
