德士古气化煤浆氧气管线的改造及优化

Renovation and optimization of CWS and oxygen pipelines in Texaco coal gasification

针对德士古加压气化炉系统水煤浆氧气管线存在的问题,进行了仔细分析和改造、优化,从而有效地实现气化炉系统的安全开车、停车,氧管泄压,手动吹扫。介绍了水煤浆加压气化炉的安全顺控,详细阐述了煤浆和氧气管线氮气吹扫的路线和顺序。

In order to solve the problems existing in the coal-water slurry and oxygen pipelines of the Texaco pressurized gasifier system, based on the careful analysis of them, a renovation and optimization was carried out, so as to effectively achieve the safe operation, outage, oxygen pipeline pressure relief and manual purging of the gasifier system. The safety sequence control of the gasifier system was introduced, and the route and sequence of nitrogen purging of water-coal slurry and oxygen pipelines were described in detail.
