Claim Text:
1. A method for ventilating a gas turbine enclosure, comprising: providing a first air flow from at least one fan of a ventilation system coupled to the gas turbine enclosure, via an air intake port, into the gas turbine engine enclosure to purge the gas turbine enclosure while a fan bypass of the ventilation system remains closed; starting up a gas turbine engine disposed within the gas turbine enclosure; igniting the gas turbine engine while the at least one fan is active; providing a second air flow, via the air intake port, into the gas turbine enclosure by opening the fan bypass, wherein the fan bypass is located outside of the gas turbine enclosure upstream of the air intake port and circumvents the at least one fan to provide the second air flow; deactivating the at least one fan upon both completion of purging the gas turbine enclosure and the gas turbine engine reaching full speed; and drawing the first or second air flows through and out of the gas turbine enclosure, via an exhaust driven eductor, using an exhaust flow output by the gas turbine engine.
