Abstract
An exemplary steam generator assembly includes a wall. Produced water acts as film cooling to at least a portion of the wall.
Claims18
A steam generator assembly, comprising:
- a combustor having a wall providing a combustion chamber, wherein the combustion chamber is axially extending and wherein within the combustion chamber a produced water acts as film cooling to at least a portion of a combustion chamber facing surface of the wall, wherein the produced water is an untreated water having a high mineral content and wherein the produced water comprises a film of produced water extending within the combustion chamber across at least a portion of the combustion chamber facing surface of the wall;
- an igniter assembly for combusting a mixture of fuel and oxidizer, the igniter assembly disposed at a first axial end of the combustion chamber;
- and
- an array of nozzles circumferentially distributed about the axis adjacent the igniter assembly to direct sprays of produced water radially outward toward the combustor wall.

A steam generator assembly, comprising:
- a combustor wall defining at least a portion of an axially extending combustion chamber;
- an igniter assembly for combusting a mixture of fuel and oxidizer, the igniter assembly disposed at a first axial end of the combustion chamber;
- an array of nozzles circumferentially distributed about the axis adjacent the igniter assembly to direct sprays of produced water radially outward toward the combustor wall;
- and
- an inlet that delivers produced water to the combustion chamber, the produced water providing film cooling within the combustion chamber to at least a portion of a combustion chamber facing surface of the combustor wall and during operation of the steam generator assembly the produced water is in direct contact with and separates combustion products from the at least a portion of the combustion chamber facing surface of the wall, wherein the produced water is an untreated water having a high mineral content.

A steam generator assembly comprising:
- a combustor wall defining at least a portion of a combustion chamber;
- an inlet that delivers produced water to the combustion chamber, the produced water providing film cooling within the combustion chamber to at least a portion of a combustion chamber facing surface of the combustor wall and during operation of the steam generator assembly the produced water is in direct contact with and separates combustion products from the at least a portion of the combustion chamber facing surface of the wall, wherein the produced water is an untreated water having a high mineral content;
- and
- including a baffle that directs a flow of produced water along at least a portion of the combustion chamber facing surface of the combustor wall.
1 more element
A steam generator assembly comprising:
- a combustor chamber defined at least in part by a wall, the wall having an inner surface within the combustion chamber, wherein a produced water acts as film cooling to at least a portion of the wall inner surface within the combustion chamber, wherein the produced water is an untreated water having a high mineral content;
- and
- including a baffle that directs a flow of produced water along at least a portion of the combustion chamber facing surface of the combustor wall.
