摘要
为保证德士古工艺烧嘴在高温下的正常工作,设计了1套单独的烧嘴冷却水保护系统,但由于联锁系统设置不完善,引发烧嘴冷却水系统频繁故障,气化炉多次跳车,严重制约了正常生产。为此通过分析研究,采取了一系列的改进措施:烧嘴冷却水泵自启动压力由1.4MPa提高至1.8MPa,脉冲宽度由2s变为20s;烧嘴冷却水泵启动方式由软启动改为硬启动,启动时间由10s缩短为2s;流量低低跳车值由12m3/h降为7m3/h,事故阀副线由DN100mm改为DN25mm。以上措施的实施,确保了气化炉的长周期稳定运行。
A separate cooling water system was designed for normal operation of the burner at high pressure and high temperature for the Texaco coal gasification technology.But the system had frequent problems due to the faultiness of the interlocking system.Some measures had been adopted to solve this problem.The self start-up pressure of the water pump was increased from 1.4 to 1.8 MPa.The pulse width was increased from 2 to 20 s.The start-up mode of the water pump is changed from soft to hard.The flow limit is redu...
