Abstract

Abstract: Aiming at the characteristics of the vacuum system of 600MW unit, the changes of unit operation parameters caused by local air leakage of the vacuum system were analyzed. The air leakage point was found out; the treatment method was put forward; and relevant measures were adopted. Then the air leakage of the vacuum system did not happen again.

Key words: vacuum system, air leakage, leakage point, hazard, treatment method
