摘要

汽轮机冷态启动升速过程中

合理安排中速暖机

提高转子金属温度

预防脆性损伤是实现汽轮机安全运行的重要内容之一。本文应用有限元计算方法

对国产300MW汽轮机冷态启动升速过程中

高、中压转子温度场进行了计算。对预防转子脆性损伤进行了分析

并提出了预防措施和建议。

Abstract

One of the most important factors influencing the safety operation of steam turbine during cold start-up is the determination of warming-up conditions and time at middle speed. Proper increase of rotor temperature can prevent rotor from brittle failure. This paper presents a calculation

by using FEM

on the temperature field of HP and LP rotors during cold start-up. Brittle failure are analyzed and prevention measures recommended.
