摘要： A shaft sealing system and method are disclosed for a high or intermediate pressure turbine section having a rotating member including a shaft and a stationary member surrounding the rotating member and defining a steam flow path. The shaft sealing system comprises at least one seal disposed about each of a first end and a second end of the shaft; and a connection line for conducting steam from the first turbine section to a downstream portion of the turbine. The downstream portion of the turbine is one of a low pressure section and a condenser, and has a lower pressure than both of the first turbine section and ambient pressure conditions.
