Abstract
A fuel supply system includes a fuel line path configured to route a fuel to a combustion inlet region. Also included is a flow manipulation member disposed proximate the fuel line path, the flow manipulation member comprising a piezoelectric material configured to cyclically manipulate a mass flow pressure of the fuel being routed through the fuel line path.
Claims20
A fuel supply system comprising:
- a fuel line path configured to route a fuel to a combustion inlet region;
- and
- a flow manipulation member disposed proximate the fuel line path, the flow manipulation member comprising a piezoelectric material configured to cyclically manipulate a mass flow pressure of the fuel being routed through the fuel line path.
A fuel supply system comprising:
- a fuel line path configured to route a fuel to a combustion inlet region;
- a valve located proximate the fuel line path;
- and
- a piezoelectric member operatively coupled to the valve and configured to cycle the valve between an open condition and a closed condition to cyclically manipulate a mass flow pressure of the fuel being routed through the fuel line path.
1 more element
A gas turbine system comprising:
- a compressor;
- a combustion assembly having at least one combustion chamber;
- a turbine section;
- and
- a fuel supply system configured to route a fuel to the combustion assembly, the fuel supply system comprising:
- a fuel line path defined by an inner surface of a wall of a pipe, the fuel line path configured to route a fuel to a combustion inlet region;
- a volume formed as a cavity in the wall of the pipe and fluidly coupled to the fuel line path via an orifice;
- and
- a flow manipulation member located within the volume and configured to cyclically manipulate a mass flow pressure of the fuel being routed through the fuel line path, wherein the flow manipulation member comprises a piezoelectric material.
