取消烟气脱硫旁路后，脱硫和锅炉烟气系统形成一个串联系统，对于原设计为单台增压风机的机组，增压风机跳闸后触发锅炉主燃料跳闸，增压风机及其附属系统运行的可靠性制约着锅炉的安全运行；为了提高设备动作的可靠性，减少机组非停，对相关控制逻辑进行优化，通过试验和论证，实现增压风机故障减负荷功能，为机组安全稳定运行和减少非计划停运提供了保障。
取消煙氣脫硫徬路後，脫硫和鍋爐煙氣繫統形成一箇串聯繫統，對于原設計為單檯增壓風機的機組，增壓風機跳閘後觸髮鍋爐主燃料跳閘，增壓風機及其附屬繫統運行的可靠性製約著鍋爐的安全運行；為瞭提高設備動作的可靠性，減少機組非停，對相關控製邏輯進行優化，通過試驗和論證，實現增壓風機故障減負荷功能，為機組安全穩定運行和減少非計劃停運提供瞭保障。

After Cancelling the flue gas desulfurization bypass,the FGD and the boiler flue gas system form a series system;The original design for a single booster fan units,the booster fan trip causes the boiler MFT ac?tion, the reliability of the booster fan and its auxiliary system restricts the safe operation of the boiler;To im?prove the reliability of the device operation,reducing the unplanned outage of unit,the relevant control logic optimized,through experiment and demonstration,realizes the booster fan runback function, provides a guaran?tee for the safe and stable operation and reduce unplanned outages.
