Abstract
Abstract A gas turbine plant including a compressor section and a turbine section housed within a multipart casing with the shafts of each section co-axial, the compressor section including a double-sided low pressure radial compressor, a high pressure radial compressor and an inter-cooler, while the turbine stage includes a first stage axial turbine on the same shaft as the compressor and at least an additional turbine stage; a heat exchanger or regenerator being included in the turbine exhaust.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
113 words
A gas turbine plant comprising: a multipart casing within which are mounted a turbine section including turbines and a radial compressor section including compressors; the turbine section including an outlet, an axial single stage turbine in driving connection with the compressors and at least one axial turbine stage mounted on an output shaft, the driving connection and output shaft being separate from one another; the compressor section including a double-stage radial compressor having a high and a low pressure stage, the low pressure stage being double sided; a compressor inter-cooler arranged between the low pressure stage and the high pressure stage; and a heat exchanger disposed in the outlet of the turbine section.
Claim 2
Dependent Claim
113 words
A gas turbine plant comprising: a multipart casing within which are mounted a turbine section including turbines and a radial compressor section including compressors; the turbine section including an outlet, an axial single stage turbine in driving connection with the compressors and at least one axial turbine stage mounted on an output shaft, the driving connection and output shaft being separate from one another; the compressor section including a double-stage radial compressor having a high and a low pressure stage, the low pressure stage being double sided; a compressor inter-cooler arranged between the low pressure stage and the high pressure stage; and a heat exchanger disposed in the outlet of the turbine section.
Claim 3
Dependent Claim
21 words
The plant as claimed in claim 1 in which the at least one axial turbine stage includes two axial turbine stages.
Claim 4
Dependent Claim
39 words
The plant as claimed in claim 1, in which the driving connection includes a first shaft, the compressors and the axial single stage turbine being arranged on the first shaft and the first shaft and output shaft being co-axial.
Claim 5
Dependent Claim
26 words
The plant as claimed in claim 1 in which a steam boiler is arranged in the outlet of the turbine section for the production of steam.
Claim 6
Dependent Claim
34 words
The plant as claimed in claim 4, including a steam cycle in the turbine outlet, the cycle comprising a closed circuit including a steam boiler, a steam turbine, a condenser and a circulation pump.
Claim 7
Dependent Claim
55 words
The plant as claimed in claim 1 including a heat exchanger in the outlet of the turbine section in combination with a Rankine cycle, the Rankine cycle comprising a closed circuit including a heat exchanger, an expansion turbine, a condenser and a circulation pump and the medium within the circuit having a low evaporation temperature.
Claim 8
Dependent Claim
30 words
The plant as claimed in claim 6 including an intermediate cycle with water as a medium, the intermediate cycle including a closed circuit comprising heat exchangers and a circulation pump.
Claim 9
Dependent Claim
23 words
