浆液循环泵是脱硫系统的重要设备，主要作用是输送混合浆液，保证浆液通过喷嘴并尽可能雾化，更重要的是降低吸收塔出口烟气温度。但是由于某些原因导致浆液循环泵全停时，其自动控制一直没有较好的应对措施。在对浆液循环泵全停原因进行分析的基础上，提出了浆液循环泵全停后的RB控制策略，并作了相关试验验证，试验结果表明：浆液循环泵全停RB控制策略对设备应急处理与机组稳定运行均具有积极作用。
漿液循環泵是脫硫繫統的重要設備，主要作用是輸送混閤漿液，保證漿液通過噴嘴併儘可能霧化，更重要的是降低吸收塔齣口煙氣溫度。但是由于某些原因導緻漿液循環泵全停時，其自動控製一直沒有較好的應對措施。在對漿液循環泵全停原因進行分析的基礎上，提齣瞭漿液循環泵全停後的RB控製策略，併作瞭相關試驗驗證，試驗結果錶明：漿液循環泵全停RB控製策略對設備應急處理與機組穩定運行均具有積極作用。

Circulation slurry pump plays important role in flue gas desulphurization system. It mainly trans-ports blended slurry to ensure the slurry can be atomized as much as possible through nozzle. The more impor-tant function is to reduce the outlet flue gas temperature of absorption tower. However , there is no good mea-sure in automatic control system when the circulation slurry pump is fully stopped due to some reasons and there is no good pertinent measure for automatic control. On the basis of expoundingthe slurry circulating pump shutdown reason analysis, processing and optimization measures, the paper puts forward a RB control strategy. The test result shows that RB control strategy for full stop of slurry circulating pump is positively meaningful for equipment emergency handling and stable operation of the units.
