烟气脱硫系统保护优化
摘要
针对旁路挡板拆除后对锅炉烟气脱硫系统(FGD)及主机运行产生的隐患
提出在原有保护及逻辑基础上
综合考虑环保因素及工况运行的合理性
大量削减设备跳闸条款及联锁保护项目
并通过增压风机的冷态及热态试验进行了验证。结果表明:旁路挡板拆除后主辅设备运行稳定
FGD保护优化效果显著。
Abstract
To solve the hidden troubles of boiler flue gas desulfurization system(FGD)and main equipments during the unit operation after the bypass baffle was removed
multiple device trip clauses and interlock protection projects were sharply reduced
by considering the environmental factors and operating conditions
on the basis of the unit original protection and logic.Moreover
the cold and hot tests for booster fans were carried out.The results show that
after the bypass baffle was removed
the major and auxiliary equipments ran stably
verifying the protection system optimization for the FGD system achieved well effects.
