Abstract
A gas turbomachine inlet system includes a duct member having an inlet portion fluidically coupled to an outlet portion through an intermediate portion. The inlet portion, outlet portion, and intermediate portion define a fluid flow zone. A throttling system is arranged in the duct member at one of the inlet portion, outlet portion and intermediate portion. The throttling system is configured and disposed to selectively establish a pressure drop through the fluid flow zone. A method of controlling inlet pressure drop through an inlet system for a gas turbomachine is also described herein.
Claims20
A gas turbomachine inlet system comprising:
- a duct member having an inlet portion fluidically coupled to an outlet portion through an intermediate portion, the inlet portion, outlet portion and intermediate portion defining a fluid flow zone;
- and
- a throttling system arranged in the duct member at one of the inlet portion, outlet portion, and intermediate portion, the throttling system being configured and disposed to selectively establish a pressure drop through the fluid flow zone.
A method of controlling the inlet pressure drop through an inlet system for a gas turbomachine, the method comprising:
- establishing an operating mode for the gas turbomachine;
- and
- adjusting a throttling system provided in a duct member of the inlet system to control the inlet pressure to the gas turbomachine based on the operating mode.
A gas turbomachine comprising:
- a compressor portion having a compressor inlet;
- a turbine portion mechanically coupled to the compressor portion;
- a combustor assembly fluidically connected to the compressor portion and the turbine portion;
- and
- an inlet system fluidically connected to the compressor inlet, the inlet system comprising:
- a duct member having an inlet portion fluidically coupled to an outlet portion through an intermediate portion, the inlet portion, outlet portion, and intermediate portion defining a fluid flow zone;
- and
- a throttling system arranged in the duct member at one of the inlet portion, outlet portion, and intermediate portion, the throttling system being configured and disposed to selectively establish a pressure drop through the fluid flow zone.
