Abstract
A gas turbine which is capable of operating in more than one pressure mode. The gas turbine, which may include a single fixed spool, multiple fixed spools, or a combination of fixed spool(s) and a free turbine, can operate in a positive pressure mode, a transatmospheric mode, or a subatmospheric mode. Valving is provided to control the particular pressure mode of operation in response to system requirements and to switch between pressure modes as required. The gas turbine is particularly useful with a catalytic combustor where the gas turbine can be started in a mode where the catalytic combustor, and its associated preheater, is at or below atmospheric pressure.
