When the steam turbine adopts an internal leakage type shaft seal system, a shaft seal heater (a shaft seal cooler) is generally arranged for heating condensate or desalted water, and shaft seal leakage steam is recovered, so that the shaft seal leakage steam and heat loss are reduced, the environmental condition of a workshop is improved, air entering along with the shaft seal leakage steam is connected to the top of the shaft seal heater by a common exhaust fan, and redundant steam is extracted by the negative pressure of the exhaust fan, so that the micro-vacuum state of the shaft seal heater is ensured. Thus, the pressure of the chamber connected with each shaft seal and the shaft seal heater is reduced, and the shaft seal steam is not leaked. Negative pressure is produced by a shaft seal air extractor or an exhaust fan, and the steam-water mixture is discharged into the air.
