摘　　要：当前,众多火力发电厂面临粉煤灰综合利用率偏低以及提升固体废物处理经济效益的挑战。针对此问题,文中选取某2×700MW超临界燃煤机组作为研究对象,设计了粉煤灰存储系统的工艺流程,并对多种输送方式及储库形式进行了对比分析。研究结果证实:构建一套直径为?46×35.6m(檐口)的有效储量为60000m3的粉煤灰存储钢板仓,并配套5.5m×6.0m×18.7m的粉煤灰发散仓,构成了最优的工艺方案。该方案投入使用后,能有效调控粉煤灰的排出量,节约了处理粉煤灰所需的土地资源和费用,同时有助于推动企业和当地社会经济的可持续发展。Currently,many coal-fired power plants are facing the challenges of low comprehensive utilization rate of fly ash and improving the economic efficiency of solid waste treatment.To address this issue,this paper selects a 2×700MW supercritical coal-fired unit as the research object,designs the process flow of fly ash storage system,and conducts comparative analysis on various transportation methods and storage forms.The research results show that the optimal process plan is to construct a fly ash storage steel drum with a diameter of∅46×35.6m(roof edge)and an effective storage capacity of 60000m 3,coupled with a fly ash divergence silo of 5.5m×6.0m×18.7m.After the plan is put into use,it can effectively regulate the amount of fly ash discharged,save land resources and costs required for fly ash treatment,and promote the sustainable development of the enterprise and local economy.
