Abstract
Abstract The present invention pertains to an apparatus for converting steam energy into electrical energy. The apparatus includes a turbine capable of converting steam energy into mechanical energy. The apparatus also includes a generator for converting mechanical energy into electrical energy. Additionally, there is a shaft disposed in and connecting the turbine and the generator along a center line. The shaft is capable of being turned by the steam energy of the turbine. There is also a single condenser connected to the turbine. The single condenser is capable of drawing steam out of the turbine and condensing steam to water. The single condenser is disposed alongside the turbine.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
109 words
A large-scale power generating apparatus for converting steam energy into electrical energy comprising: a large turbine capable of converting steam energy into mechanical energy; a large generator for converting mechanical energy into electrical energy; a shaft disposed in and axially connecting the turbine and the generator, said shaft capable of being turned by steam energy in the turbine; a single condenser connected to the turbine and capable of drawing steam out of the turbine and condensing steam to water, said single condenser disposed alongside the turbine; and a low foundation which supports the turbine and the generator and a slab which supports the low foundation and the single condenser.
Claim 2
Dependent Claim
109 words
A large-scale power generating apparatus for converting steam energy into electrical energy comprising: a large turbine capable of converting steam energy into mechanical energy; a large generator for converting mechanical energy into electrical energy; a shaft disposed in and axially connecting the turbine and the generator, said shaft capable of being turned by steam energy in the turbine; a single condenser connected to the turbine and capable of drawing steam out of the turbine and condensing steam to water, said single condenser disposed alongside the turbine; and a low foundation which supports the turbine and the generator and a slab which supports the low foundation and the single condenser.
Claim 3
Dependent Claim
46 words
An apparatus as defined in claim 1 wherein the turbine has a low pressure region, and there is included a low pressure exhaust that is connected to the single condenser through which steam in the low pressure region is capable of passing into the single condenser.
Claim 4
Dependent Claim
85 words
An apparatus as described in claim 2 wherein there is a center line along which the shaft axially connects the turbine and the generator; and the low pressure exhaust is positioned about the center line of the low pressure region in the turbine and the single condenser is fluidically connected with the low pressure region in the turbine such that the shaft is not displaced from the center line by the single condenser as it draws steam from the low pressure region in the turbine.
Claim 5
Dependent Claim
21 words
An apparatus as described in claim 1 which includes a vacuum anchor for transversely securing the turbine to the low foundation.
Claim 6
Dependent Claim
34 words
An apparatus as defined in claim 4 including a rigid joint disposed between the low pressure exhaust and the single condenser for securing the low pressure exhaust of the turbine to the single condenser.
Claim 7
Dependent Claim
30 words
An apparatus as described in claim 5 including feet and axial anchors which vertically and axially, respectively, secure the turbine to the low-foundation while allowing for transverse thermal expansion movement.
Claim 8
Dependent Claim
31 words
An apparatus as described in claim 6 including springs, flexiplates or sliding supports with which the single condenser is flexibly mounted to the slab while allowing for transverse thermal expansion movement.
Claim 9
Independent Claim
104 words
An apparatus for converting steam energy into electrical energy comprising: a turbine capable of converting steam energy into mechanical energy; a generator for converting mechanical energy into electrical energy; a shaft disposed in and axially connecting the turbine and the generator, said shaft capable of being turned by steam energy in the turbine; a single condenser connected to the turbine and capable of drawing steam out of the turbine and condensing steam to water, said single condenser disposed alongside the turbine; and a low foundation which supports the turbine and the generator and a slab which supports the low foundation and the single condenser.
Claim 10
Independent Claim
104 words
An apparatus for converting steam energy into electrical energy comprising: a turbine capable of converting steam energy into mechanical energy; a generator for converting mechanical energy into electrical energy; a shaft disposed in and axially connecting the turbine and the generator, said shaft capable of being turned by steam energy in the turbine; a single condenser connected to the turbine and capable of drawing steam out of the turbine and condensing steam to water, said single condenser disposed alongside the turbine; and a low foundation which supports the turbine and the generator and a slab which supports the low foundation and the single condenser.
Claim 11
Dependent Claim
46 words
An apparatus as defined in claim 8 wherein the turbine has a low pressure region; and there is included a low pressure exhaust that is connected to the single condenser through which steam in the low pressure region is capable of passing into the single condenser.
Claim 12
Dependent Claim
85 words
An apparatus as described in claim 9 wherein there is a center line along which the shaft axially connects the turbine and the generator; and the low pressure exhaust is positioned about the center line of the low pressure region in the turbine and the single condenser is fluidically connected with the low pressure region in the turbine such that the shaft is not displaced from the center line by the single condenser as it draws steam from the low pressure region in the turbine.
Claim 13
Dependent Claim
16 words
An apparatus as described in claim 10 wherein the condenser is flexibly mounted to the slab.
Claim 14
Dependent Claim
21 words
An apparatus as described in claim 11 which includes a vacuum anchor for transversely securing the turbine to the low foundation.
Claim 15
Dependent Claim
34 words
An apparatus as defined in claim 12 including a rigid joint disposed between the low pressure exhaust and the single condenser for securing the low pressure exhaust of the turbine to the single condenser.
Claim 16
Dependent Claim
30 words
An apparatus as described in claim 13 including feet and axial anchors which vertically and axially, respectively, secure the turbine to the low-foundation while allowing for transverse thermal expansion movement.
Claim 17
Dependent Claim
