Abstract

A shaft sealing system and method are disclosed for a high or intermediate pressure turbine section having a rotating member (120) including a shaft (130) and a stationary member (140) surrounding the rotating member (120) and defining a steam flow path (150). The shaft sealing system comprises at least one seal disposed about each of a first end (172) and a second end (174) of the shaft (130); and a connection line (200) for conducting steam from a first turbine section (110) to a downstream portion (210) of the turbine. The downstream portion (210) of the turbine is one of a low pressure section and a condenser (220), and has a lower pressure than both of the first turbine section (110) and ambient pressure conditions.
