Abstract
Abstract A gas turbine power plant having a combustion section defined by a casing structure divided into upper and lower semi-cylindrical casing halves along a horizontal plane. The casing halves encompass an annular array of combustion chambers equally spaced from the central axis of the turbine. The end wall of the casing structure has an annular array of equally spaced openings, at least one of the openings having a smaller diameter than the maximum diameter of the associated combustion chamber. This enables a closer clustering of the combustion chambers and a corresponding decrease in the diameter of the casing structure.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
149 words
A gas turbine power plant which comprises: a combustion section having a casing structure; said casing structure being circular in cross section and being divided into two halves by a plane passing through the central axis of the power plant; a plurality of combustion chambers annularly disposed within said casing structure and the centers of said chambers being equidistant from the central axis of the power plant; said casing structure having an upstream annular end wall portion, a removable intermediate portion, and a downstream end wall portion; said upstream end wall portion having an annular array of openings corresponding to said combustion chambers; and at least one of said end wall openings having a smaller diameter than the maximum outer diameter of the associated combustion chamber so that said opening obstructs removal of the associated combustion chamber therethrough, and said combustion chamber being radially removable through said intermediate portion.
Claim 2
Dependent Claim
149 words
A gas turbine power plant which comprises: a combustion section having a casing structure; said casing structure being circular in cross section and being divided into two halves by a plane passing through the central axis of the power plant; a plurality of combustion chambers annularly disposed within said casing structure and the centers of said chambers being equidistant from the central axis of the power plant; said casing structure having an upstream annular end wall portion, a removable intermediate portion, and a downstream end wall portion; said upstream end wall portion having an annular array of openings corresponding to said combustion chambers; and at least one of said end wall openings having a smaller diameter than the maximum outer diameter of the associated combustion chamber so that said opening obstructs removal of the associated combustion chamber therethrough, and said combustion chamber being radially removable through said intermediate portion.
Claim 3
Dependent Claim
29 words
The structure recited in claim 1 wherein all of the end wall openings corresponding to the combustion chambers have smaller diameters than the diameter of the associated combustion chambers.
Claim 4
Dependent Claim
21 words
The structure recited in claim 2 wherein the end wall openings accommodate means to supply combustible fuel to the combustion chambers.
Claim 5
Dependent Claim
40 words
The structure recited in claim 1 wherein each casing half has a mating horizontally extending flange disposed adjacent the central horizontal plane, and where at least one of the combustion chambers extends into a horizontal region defined by the flanges.
Claim 6
Dependent Claim
25 words
The structure recited in claim 1 wherein at least one of the combustion chambers is disposed partially in both the upper and lower casing halves.
Claim 7
Dependent Claim
30 words
The structure recited in claim 1 wherein at least one of said end wall openings has a diameter at least as great as the diameter of the associated combustion chamber.
Claim 8
Dependent Claim
40 words
The structure as recited in claim 6 wherein each casing half has a mating horizontally extending flange adjacent the central horizontal plane; and where at least one of the combustion chambers extends into a horizontal rEgion defined by said flanges.
Claim 9
Dependent Claim
24 words
The structure recited in claim 6 wherein at least one of said combustion chambers is partially disposed in the upper and lower casing halves.
Claim 10
Dependent Claim
22 words
The structure recited in claim 1 wherein the casing structure of the combustion section is cylindrical and the end wall is dome-shaped.
Claim 11
Dependent Claim
29 words
The structure recited in claim 1 wherein at least one of the smaller diameter end wall openings and the associated combustion chamber is disposed adjacent the central horizontal plane.
Claim 12
Dependent Claim
22 words
The structure recited in claim 1 wherein the casing structure defines an annular plenum chamber, and the combustion chambers are disposed therein.
Claim 13
Dependent Claim
32 words
The structure recited in claim 1 wherein each combustion chamber is of the step-liner type and has at least one liner having a maximum diameter and one liner having a minimum diameter.
