摘　　要：为改善烟气能量回收机组开机时直接启动大功率电机对电网的冲击,中国石油化工股份有限公司金陵分公司Ⅰ套催化裂化装置改变了烟气轮机组的启动方案,采用烟气先冲转至机组额定转速的80%再启动电机,以降低电机启动电流、缩短启动时间,保证电网中其它设备的安全运行。对烟气冲转启动烟气轮机-风机-电机三机组的实施过程进行了技术分析,明确了操作要点,并根据三机组启动过程转速对关键参数的影响提出了改进建议。SINOPEC Jinling Company modified its start-up procedures of flue gas expander train of the No.1 FCCU to minimize the surge to the local power grid at the start-up of flue gas expander train.The expander is first impulse rotated to the 80%of the rated speed of the train before start-up of motor so as to reduce the start-up current of the motor,shorten the start-up time and ensure the safe operation of other equipment in the power grid.The procedures for impulse start-up of expander-air blower-motor train are...
