Abstract

Abstract: The reason and purpose of the gland seal reformation of a 600MW unit in Hebi Fenghe Power Generation Company Limited were analyzed. The theory and functions of DAS gland seal and the comparison with other type gland seals were introduced. The improvement of the unit in vibration and heat consumption rate after reformation were compared with those before reformation, and the evaluation of the reformation effects of DAS gland seal was obtained.

Key words: DAS gland seal, reformation, stream excited vibration, heat consumption rate
