Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
170 words
A face plate for protecting components of a combustor injector from excessively high temperatures, said face plate comprising: a thin plate of a thermally highly conductive material secured to said injector, said plate having an inner surface, an outer surface having a peripheral edge, a plurality of injector openings extending from said inner surface to said outer surface through said plate, each opening having an oxidizer injector fixedly received therein, a plurality of first cooling holes extending from said inner surface to said outer surface through said plate, each of said first cooling holes located adjacent one of said openings and equally spaced thereabout for delivering cooling fluid through the plate to cool said plate, said first cooling holes spaced equidistant from said adjacent opening, and a plurality of second cooling holes extending from said inner surface to said outer surface through said plate, each of said second cooling holes located adjacent the peripheral edge for delivering cooling fluid through the plate to cool said plate adjacent the peripheral edge.
Claim 2
Dependent Claim
170 words
A face plate for protecting components of a combustor injector from excessively high temperatures, said face plate comprising: a thin plate of a thermally highly conductive material secured to said injector, said plate having an inner surface, an outer surface having a peripheral edge, a plurality of injector openings extending from said inner surface to said outer surface through said plate, each opening having an oxidizer injector fixedly received therein, a plurality of first cooling holes extending from said inner surface to said outer surface through said plate, each of said first cooling holes located adjacent one of said openings and equally spaced thereabout for delivering cooling fluid through the plate to cool said plate, said first cooling holes spaced equidistant from said adjacent opening, and a plurality of second cooling holes extending from said inner surface to said outer surface through said plate, each of said second cooling holes located adjacent the peripheral edge for delivering cooling fluid through the plate to cool said plate adjacent the peripheral edge.
Claim 3
Dependent Claim
22 words
The face plate of claim 1 wherein each oxidizer injector is brazed into the opening in which the injector element is received.
Claim 4
Dependent Claim
20 words
The face plate of claim 2 wherein said openings form a hexagonal pattern on the outer surface of the plate.
Claim 5
Dependent Claim
13 words
The face plate of claim 3 wherein the cooling fluid is a fuel.
Claim 6
Dependent Claim
20 words
The face plate of claim 4 wherein thickness of the plate between the inner and outer surfaces is 0.2 inches.
Claim 7
Dependent Claim
13 words
The face plate of claim 5 wherein the plate is made of copper
