Abstract: A foundation temperature control system for use with a rotary machine is positioned between the rotary machine and a foundation. The foundation temperature control system includes a heat shield, an insulation pack positioned below the heat shield, and an air gap at least partially defined by the heat shield and the insulation pack. The heat shield, the insulation pack, and the air gap are oriented to facilitate maintaining a temperature of the foundation supporting the rotary machine below a maximum rated operating temperature of the foundation.

Abstract: A gas turbine system includes a load coupling connecting a gas turbine to a generator. A load coupling guard surrounds the load coupling to define an enclosed spaced around the load coupling. The load coupling guard includes a porous sleeve such that hydrogen coolant leaked into the load coupling guard from the generator is vented to ambient air.

Abstract: The present application provides a gas turbine engine. The gas turbine engine may include a compressor air extraction system with a number of valves, an exhaust frame cooling system with an exhaust frame blower, and a turbine valve cooling system with one or more valve protection boxes surrounding one or more of the valves. The valve protection boxes may be in communication with a flow of air from the exhaust frame blower.
