基于Aspen Plus的CaO/CaCO3热化学储能与光热发电集成系统建模及分析
Modeling and analysis of CaO/CaCO3 fluidized thermochemical energy storage system based on Aspen Plus
摘要
Abstract
With the rapid development of renewable energy,its increasing reliance on large-scale energy storage systems has become more prominent.This study established a MW-scale CaO/CaCO3 thermochemical energy storage system integrated with concentrated solar power using Aspen Plus process simulation software.The impacts of reactor geometry,particle size,temperature and other parameters on reactor configuration and system performance were systematically analyzed.Results indicate that under 0.33 MPa pressure,the equilibrium temperature approximates 950℃,while near-complete conversion can be achieved at 850℃in practical operation.With a reactor height-to-diameter ratio of 2.0 and particle size of 300 μm,the system achieves a carbonation conversion rate of over 95%at a low entrainment(0.13 kg/s),while maintaining stable bed inventory in the fluidized bed reactor,thereby balancing reaction efficiency and operational economy.The cycle efficiency of the system in steady-state operation reaches 41%and the round-trip efficiency reaches 36%.关键词
