โœฆ Synopsis

Tandem dry seals installed in centrifugal pipeline compressors are susceptible to contamination from the process gas and from the lube oil system during upset conditions. Contamination found within a dry seal can include lube oil grease, condensate, glycol, pipe scale and desiccant. Over time, contamination can collect to a degree which influences the performance of the dry seal. The deterioration in performance is characterized by erratic first stage seal leakage during operation, or during a start up. To restore performance, it is typically necessary to remove the seal, refurbish a&l replace internal seal components.

In a large aircraft gas turbine, around 10% of the core airflow bypasses the high pressure turbine nozzle guide vanes. Half of this cools the blade and vane, and half is used for disc cooling and rim senllng -which latter half accounts for a 5% drain on fuel consnmption. Commercial pressure therefor
