摘　　要：以工业余热跨季节储热用于区域供热系统为研究对象,在一个已有的1 MW工业余热系统的基础上,搭建工业余热跨季节储热系统设计方案,通过系统模拟对系统储热、取热过程进行分析。分析结果表明:工业余热跨季节储热适合长周期、大规模蓄热;储热体体积和循环流量应根据系统热源和取热装置特性进行合理匹配,在合理匹配范围内可参考系统经济性确定系统最优配置。最后,通过费用年值法分析优化后的系统经济性,分析表明工业余热跨季节储热用于区域供热成本仅略高于燃煤供热,相比燃气供热具有非常可观的经济性。A design scheme of an industrial waste heating system with large scale borehole thermal energy storage is established based on a 1 MW realistic industrial waste heat recovery system. Both heat injection and extraction processes were studied based on system simulation. The study results showed that the integration of industrial waste heat and seasonal thermal storage is a good way to maximize the utilization of industrial waste heat in urban district heating;The correlation of storage volume and circulating flow rate has significant effect on system thermal performance and economy. Therefore,the correlation should be identified according to the characteristics of the heat source and heat extraction device of the system.Annualized system cost analysis showed that,the industrial waste heat heating system with seasonal thermal storage has a significant system economy. The annualized cost of the designed system is slightly lower than coal-fire heating system,and far better than natural gas heating system.
