介绍了油挡积碳对1000 MW超超临界机组运行的影响,根据油挡积碳的机理分析了影响因素。实践证明,油挡改造后可以有效避免汽轮机油碳化摩擦振动。
The effect of oil coking on the operation of 1000 MW ultra-supercritical units is introduced. The influencing factors are analyzed according to the mechanism of carbon deposition. Practice has proved that after the oil block can be modified to effectively prevent the turbine oil carbonation friction vibration.
