催化裂化装置烟气轮机轮盘应力与寿命分析

Analysis of stress and life of rotor disk of FCC flue gas expander

采用弹性有限元方法,计算分析了烟气轮机转子轮盘在正常转速和超转速下的应力与寿命,对比判断了烟气轮机转子轮盘的使用性能,为烟气轮机安全运转提供理论依据。

The elastic finite element technique is adopted to calculate and analyze the stress and life of flue gas expander＇ s rotor disk at normal and ultra-high speeds. The operation performance of rotor disk is compared and studied to provide the theoretical basis for the reliable operation of the gas expander.
