Abstract
Systems and methods include one or more fluid lines configured to flow a fluid in a first direction in the gas turbine system. The systems and methods also include an eductor configured to reverse flow of the fluid in the one or more fluid lines during a reverse purge of the gas turbine system.
Claims20
A gas turbine system, comprising:
- one or more fluid lines configured to flow a fluid in a first direction in the gas turbine system;
- and
- an eductor configured to reverse flow of the fluid in the one or more fluid lines during a reverse purge of the gas turbine system, wherein the eductor comprises:
- a body;
- a cavity in the body;
- a fluid inlet coupled to the cavity, wherein the fluid inlet is coupled to the one or more fluid lines;
- a motive fluid inlet coupled to the cavity, wherein the motive fluid inlet is configured to receive a motive fluid to cause a reduced pressure to suck the fluid from the one or more fluid lines through the fluid inlet into the cavity;
- and
- a fluid outlet configured to discharge the fluid and the motive fluid, wherein the fluid is not a combustible fuel.
6 more elements
A gas turbine system, comprising:
- a compressor;
- one or more fluid lines configured to flow a fluid in a first direction into a flow path that passes through the compressor;
- and
- an eductor configured to reverse flow of the fluid in the one or more fluid lines during a reverse purge of the gas turbine system, wherein the eductor comprises:
- a body;
- a cavity in the body;
- a fluid inlet coupled to the cavity, wherein the fluid inlet is coupled to the one or more fluid lines;
- a motive fluid inlet coupled to the cavity, wherein the motive fluid inlet is configured to receive a motive fluid to cause a reduced pressure to suck the fluid from the one or more fluid lines through the fluid inlet into the cavity;
- and
- a fluid outlet configured to discharge the fluid and the motive fluid, wherein the fluid is different from the motive fluid.
7 more elements
A method comprising
- supplying fluid to a gas turbine system using one or more fluid lines in a first direction during operation of the gas turbine system;
- and
- purging the fluid from the one or more fluid lines using an eductor to reverse flow from the first direction to a second direction, wherein purging the fluid comprises:
- receiving a motive fluid through a motive fluid inlet into a cavity of the eductor to cause a reduced pressure to suck the fluid from the one or more fluid lines through a fluid inlet into the cavity;
- and
- discharging the fluid and the motive fluid through a fluid outlet of the eductor, wherein the fluid is not a combustible fuel.
