摘    要:
针对现有选煤厂煤流系统启停车技术存在启停车时间长、耗电量较大的问题, 提出了一种选煤厂煤流系统启停车技术优化方案。以同一台变压器供电的煤流系统设备为启动单元, 根据变压器负荷率, 同一启动单元内设备同时启动或按设定顺序分批启动, 且不同启动单元同时启动;人工测定煤流系统各设备无煤时间节点, 在此基础上延后35s作为设备停车时间节点, 按顺煤流方向实现各设备无煤即停。实际应用结果表明, 采用优化的启停车技术后, %, %, 取得了良好的节能效果。

Abstract:
For problems of long starting and stopping time and large power consumption existed in current starting and stopping technology for coal flow system of coal preparation plant, an optimization scheme of starting and stopping technology for coal flow system of coal preparation plant was of coal flow system powered by the same transformer are taken as starting in the same starting unit start simultaneously or start in batches in set sequence according to load factor of the transformer, and different starting units start -coal time node of each equipment of coal flow system is measured manually, and equipme
