摘　　要：多喷嘴水煤浆气化工艺中设置的烧嘴冷却水系统保护联锁,在烧嘴拆装、投料升压过程中和烧嘴冷却水进出口切断阀故障关闭时均存在检测盲区,不能全面有效检测烧嘴的运行情况。针对检测盲区进行分析,提出优化思路,以健全和完善烧嘴冷却水故障联锁体系。Non-detection zone often exists in burner cooling water interlock system in multi-nozzle water slurry coal gasification process at the time of assembly and disassembly of the burner, during the process of feeding and pressurizing, and when the block valves at the inlet and outlet of burner cooling water were closed, leading to incomplete and ineffective detection of the burner. The analysis on the non-detection zone has brought an optimizing idea to make the interlock system robust and perfect.
