ABSTRACT:
An improved bell seal arrangement for steam turbines wherein the bell seal is modified by the addition of a special, replaceable, cylindrical extension seal for sealing the leakage gap between the bell seal and the turbine inner shell, the extension seal being threadably attached and secured to the modified bell seal to insure against vibration, and when wear or damage occurs to the extension seal surface, being replaceable without requiring complete removal or replacement of the modified, existing bell seal.
