The number of sealing teeth was increased in existing cavity, the sealing gap was narrowed as long as not affecting safety, teeth thickness was reduced as long as not af-fecting the service life of the sealing and the sealing structure was improved through modifi-cation of the steam sealing with new-type cellular steam sealing, which has enhanced the power generating efficiency of the unit.
