摘要
汽轮机的空气快速冷却以加热后的空气作为冷却介质,具有低的放热系数,加热到合适的温度可减少对汽轮机金属部件的热冲击,连接系统简单,操作简便,缩短检修工期以减少对外限电的损失。
Heated air,used as cooling medium for steam turbine fast cooling down,has low heat release coefficient.It can reduce the heat impact to the metal parts of steam turbine when it is heated to a suitable temperature.This method is easy to connect to a system and convenient to operate,and it can also shorten the maintenance duration and minimize the shut down loses of the unit in maintenance.
