摘要
某厂单台空预器在长时间运行中,联轴器对轮与减速机Ⅰ级齿轴焊接处开裂,空预器减速机与主电机脱开。辅助电机启动后,运行状态反馈失误。由于状态有误引起RB动作,从而导致一次风机出力偏大引起灭火。针对该事故,提出防止空预器改造方案,并制定了防范措施,保证了机组安全运行。
In a single plant air preheater in the long run the air heater trip in the high and low unit load, bring challenges to the safe operation of unit. Analyzes through the working principle and structures of induced draft fan,the performance curve of parallel operation fans, stall and surge generated process, write leading technical measures of induced draft fan. Practice proves avoid events of reduce the unit output and boiler fire extinction. To provide reference for the stable operation of the same unit.
