大庆炼化公司烟机运行总结

A Review of the Performance of Flue Gas Turbines of PetroChina Daqing Refining and Chemical Co.

介绍了大庆炼化公司使用的YL-15000A型、YL-10000C型烟机的运行情况。重点介绍了YL-10000C型烟机的结垢情况并分析了结垢产生的原因,提出了解决结垢问题的措施及应用效果。通过对烟机轮盘冷却蒸汽流程进行调整,对三旋灰斗下料不畅问题进行整改,对再生器二级旋分料腿进行加粗改造,加强工艺及设备的各类操作指标的控制与管理,有效地遏制了烟机结垢。最后总结了关于烟机运行的几点体会。

This article reviews the operation of the YL-15000A and YL-10000C flue gas turbines in PetroChina Daqing Refining and Chemical Company,focusing on the causes of the scale buildup in the YL-10000C turbine.It recommends several solutions to this problem and describes their effectiveness.In a case study presented in the article,technicians effectively checked scale buildup by adjusting the cooling steam process for the wheel discs of the flue gas turbine,improving the ash bucket blanking for the three-stage cyclone,coarsening the dipleg for the two-stage cyclone of the regenerator and strengthening the control and management of various operating indices for process and equipment.At the end of the article,the authors talk about their own experience in operating flue gas turbines.
