摘　　要：为了解决超临界循环流化床锅炉在发生辅机故障减负荷(RB)时,由于操作人员无法手动快速干预调整机组参数而产生非计划停机的问题,笔者以某铝厂自备电厂350 MW循环流化床锅炉的火电机组为研究对象,论述RB功能系统特有的控制难点,并提出相应可行的控制措施。通过RB热态试验,结果表明RB控制策略的有效性、可靠性、安全性,可为同类型火电机组RB控制系统试验优化提供参考及借鉴。In order to solve the problem of unplanned shutdown caused by the inability of operators to manually and quickly adjust unit parameters when the supercritical circulating fluidized bed boiler has runback RB the author takes the thermal power unit of a 350 MW circulating fluidized bed boiler in an aluminum plant as the research object discusses the unique control difficulties of the RB function system and proposes corresponding feasible control measures.Through the RB thermal test the results show that the RB control strategy is effective reliable and safe which can provide reference for the test optimization of RB control system of the same type of thermal power unit.
