Method for meeting a purge flow requirement for a power plant and a power plant having a purge control system

A method of delivering a purge flow through a gas turbomachine (4) includes generating a purge flow, guiding the purge flow through at least one of a combustor assembly (14) and a turbine portion (12) of the gas turbomachine (4), determining a cumulative purge volume passing through the one of the c...

Zusammenfassung:	A method of delivering a purge flow through a gas turbomachine (4) includes generating a purge flow, guiding the purge flow through at least one of a combustor assembly (14) and a turbine portion (12) of the gas turbomachine (4), determining a cumulative purge volume passing through the one of the combustor assembly (14) and the turbine portion (12) of the gas turbomachine (4) to determine a predetermined purge volume, and discontinuing the purge flow once the predetermined purge volume has passed through the one of the combustor assembly (14) and the turbine portion (12) of the gas turbomachine (4).
