摘　　要：为解决发电厂灰库现场卸灰环境差,人力浪费的难题,提出了一种新的组合式设计方案,将发电厂灰库的手动卸料改为PLC系统卸料,同时与闭路电视视频监控相结合,形成一个协同作业的卸灰监控系统,使得多个库的卸灰能在干净的值班室内统一简便的完成。这种新的设计方法在景德镇2x660MW超超临界机组新建工程中得到成功应用,使得在灰库值班室内能自由监控三个灰库的卸灰,这种新的设计方案对今后的发电厂灰库值班系统的设计具有指导意义。To solve the bad circumstance,manpower waste problem of the power plant,this article propose a new combined design scheme,by change the manual unloading into PLC control unloading and associate with CCTV video monitoring system,what finally forms a collaborative process ash unloading monitoring control system,and make ash unloading for multiple silos so convient in a unified clean duty room.This new concept has been successfully applied in Jingdezhen 2×660MW ultra super critical new built power plant project,and realize the function that three ash silo unloading monitoring in a ash silo duty room,and this new design scheme has guiding significance to design of future power plant ash silo duty system.
