Abstract
A system is provided with an ejector having an outer wall extending circumferentially about a flow path, wherein the outer wall has a throat section along the flow path, and a diverging section downstream from the throat section along the flow path. The ejector includes a gas inlet configured to supply a gas into the flow path, and a water inlet configured to supply water into the flow path. The ejector is configured to produce steam in response to mixing of the water and the gas along the flow path. The system also includes a controller configured to control flows of the gas and the water to produce the steam for a steam purge of a liquid fuel circuit.
Claims20
A system, comprising:
- an ejector, comprising:
- an outer wall extending circumferentially about a flow path, wherein the outer wall comprises a throat section along the flow path, and a diverging section downstream from the throat section along the flow path;
- a gas inlet configured to supply a gas into the flow path;
- a water inlet configured to supply water into the flow path, wherein the ejector is configured to produce steam in response to mixing of the water and the gas along the flow path;
- a controller configured to control flows of the gas and the water to produce the steam for a steam purge of a liquid fuel circuit.
A system, comprising:
- a liquid fuel circuit;
- and
- a steam purge system configured to purge the liquid fuel circuit with steam, wherein the steam purge system comprises an ejector, comprising:
- an outer wall extending circumferentially about a flow path, wherein the outer wall comprises a throat section along the flow path, and a diverging section downstream from the throat section along the flow path;
- a gas inlet configured to supply a gas into the flow path;
- and
- a water inlet configured to supply water into the flow path, wherein the ejector is configured to produce the steam in response to mixing of the water and the gas along the flow path.
A method, comprising:
- controlling flows of a gas and water to an ejector of a steam purge system fluidly coupled to a liquid fuel circuit, wherein the ejector comprises an outer wall extending circumferentially about a flow path, the outer wall comprises a throat section along the flow path, the outer wall comprises a diverging section downstream from the throat section along the flow path, the ejector comprises a gas inlet configured to supply the gas into the flow path, the ejector comprises a water inlet configured to supply the water into the flow path, and the ejector is configured to produce the steam in response to mixing of the water and the gas along the flow path;
- and
- opening a flow of the steam from the ejector to the liquid fuel circuit to purge the liquid fuel circuit.
