Title: Turbine and methods of assembling the same

Abstract

A turbine operable with a first fluid and a second fluid is provided. The turbine includes a shaft and having a dry gas seal area, a balance area, and a shaft surface. The turbine also includes a stationary component coupled to a housing and having a first side and a second side and defining a channel in flow communication with the shaft surface. A heat exchange assembly is coupled to the housing and in flow communication with the shaft and the stationary component. The heat exchange assembly includes a first flow path coupled in flow communication with the dry gas seal area and the channel and configured to direct the first fluid along the first side. Heat exchange assembly also includes a second flow path coupled in flow communication with the balance area and channel and configured to direct the second fluid along the second side.
