火力发电厂脱硫系统取消旁路后的设备及运行优化

Equipment reformation and operation optimization of desulphurization system after bypass is cancelled in power plant

脱硫系统取消旁路后,对机组运行存在的风险性进行了分析,采取了逻辑优化、运行优化和设备改造的措施,提高了脱硫系统运行可靠性。改造后的运行情况表明,脱硫运行周期完全能够满足机组检修周期的运行要求。

There are some risks in unit operation after the desulphurization bypass of the unit was cancelled. The risks were analyzed. Some measures of the logic optimization,the operation optimization and the equipment reformation were adopted. After the system had been reformed,the operation reliability of the desulphurization system was improved,and the operation period of the desulphurization system is suitable for the repair cycle of the unit.
