Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
32 words
In a method of producing power in a gas turbine, the improvement which comprises injecting and combusting a fuel with air in the presence of a combustion catalyst in said gas turbine.
Claim 2
Dependent Claim
32 words
In a method of producing power in a gas turbine, the improvement which comprises injecting and combusting a fuel with air in the presence of a combustion catalyst in said gas turbine.
Claim 3
Dependent Claim
43 words
In a system for producing power including a gas turbine, the improvement which comprises providing combustion means for injecting and firing a fuel into said turbine and means for providing a catalyst in said gas turbine to improve the combustion of said fuel.
Claim 4
Dependent Claim
43 words
In a system for producing power including a gas turbine, the improvement which comprises providing combustion means for injecting and firing a fuel into said turbine and means for providing a catalyst in said gas turbine to improve the combustion of said fuel.
Claim 5
Dependent Claim
44 words
In a method of producing power in a gas turbine, the improvement which comprises injecting and combusting a fuel with air in the presence of a combustion catalyst in said gas turbine to thereby maintain the expansion of said gas at substantially isothermal conditions.
Claim 6
Dependent Claim
44 words
In a method of producing power in a gas turbine, the improvement which comprises injecting and combusting a fuel with air in the presence of a combustion catalyst in said gas turbine to thereby maintain the expansion of said gas at substantially isothermal conditions.
Claim 7
Dependent Claim
26 words
A method according to claim 3 wherein said combustion is carried out by injecting said fuel in increments at two or more points in said turbine.
Claim 8
Dependent Claim
36 words
A method according to claim 3 wherein the fuel injected into said turbine is a liquid fuel and contains at least about 2% water to thereby aid in the atomization of said fuel in said turbine.
Claim 9
Dependent Claim
24 words
A method according to claim 3 wherein the temperature is greater than about 1000° F. and the pressure is greater than about 10 atmospheres.
Claim 10
Dependent Claim
18 words
A method according to claim 3 wherein said air is compressed prior to feeding it to said turbine.
Claim 11
Dependent Claim
22 words
A method according to claim 7 wherein said compressed air is indirectly heat exchanged with the exhaust gas from said gas turbine.
Claim 12
Dependent Claim
55 words
In a system for producing power including a gas turbine, the improvement which comprises providing combustion means for injecting and firing a fuel into said turbine to thereby maintain the expansion of the gas at substantially isothermal conditions and means for providing a catalyst in said gas turbine to improve the combustion of said fuel.
Claim 13
Dependent Claim
55 words
In a system for producing power including a gas turbine, the improvement which comprises providing combustion means for injecting and firing a fuel into said turbine to thereby maintain the expansion of the gas at substantially isothermal conditions and means for providing a catalyst in said gas turbine to improve the combustion of said fuel.
Claim 14
Dependent Claim
25 words
A power system according to claim 9 wherein said combustion means includes fuel injection means for injecting fuel in increments at two or more points.
Claim 15
Dependent Claim
32 words
A power system according to claim 9 including a combustion means for injecting and firing fuel in said air to thereby heat said air prior to passing it into said gas turbine.
Claim 16
Dependent Claim
22 words
A power system according to claim 9 including a compression means for compressing air to be fed to the said gas turbine.
Claim 17
Dependent Claim
25 words
A power system according to claim 12 including indirect heat exchange means for heating said compressed air with the exhaust gas from said gas turbine.
