First Claim
Patent Images
1. A system, comprising:
- a gas turbine enclosure;
a gas turbine engine disposed in the gas turbine enclosure, wherein the gas turbine engine is configured to output an exhaust flow; and
a ventilation system coupled to the gas turbine enclosure, wherein the ventilation system comprises;
at least one fan configured to provide a first air flow into the gas turbine enclosure via an air intake port;
a fan bypass located outside of the gas turbine enclosure upstream of the air intake port and configured to circumvent the at least one fan to provide a second air flow into the gas turbine enclosure via the air intake port;
wherein the fan bypass comprises an actuator coupled to a valve;
an exhaust driven eductor configured to draw the first or second air flows through and out of the gas turbine enclosure using the exhaust flow and wherein the gas turbine enclosure comprises an exit port, and wherein, during the operation of the ventilation system, the first air flow, the second air flow, and the exhaust flow exit the gas turbine enclosure via the exit port.
