Abstract
Abstract A plant for the generation by means of a gaseous fluid of mechanical energy comprising an assembly consisting of a gas turbine (1) with a combustion chamber (4) and a compressor unit (C) driven by a turbine (T). The turbine (T) is fed by compressed air from the unit (C) after its passage through a main heat exchanger (3) arranged in the exhaust of the gas turbine (1). The outlet (10) of the compressor-turbine (T) is in fluid communication with the combustion chamber (4).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
184 words
A plant for the generation of mechanical energy by using a fluid, the plant comprising: (a) a gas turbine; (b) a plurality of compressor units; (c) a plurality of compressor turbines for driving the compressor units, the compressor turbines being connected in series with the compressor units; (d) a combustion chamber connected with the gas turbine, the expanded air from the compressor turbines being directed into the combustion chamber; (e) a main heat exchanger being disposed between the compressor turbines and the compressor units, the exhaust from the gas turbine being directed through the main heat exchanger; (f) an interim heat exchanger being disposed between the compressor units; (g) a first external heat exchanger being disposed downstream of the main heat exchanger; and (h) a second external heat exchanger being disposed between the last compressor turbine and the combustion chamber of the gas turbine; wherein the first and the second external heat exchangers enable a predetermined h/p ratio to be achieved between the thermal power given off in the interim and the external heat exchangers and the mechanical power delivered to the gas turbine.
Claim 2
Dependent Claim
184 words
A plant for the generation of mechanical energy by using a fluid, the plant comprising: (a) a gas turbine; (b) a plurality of compressor units; (c) a plurality of compressor turbines for driving the compressor units, the compressor turbines being connected in series with the compressor units; (d) a combustion chamber connected with the gas turbine, the expanded air from the compressor turbines being directed into the combustion chamber; (e) a main heat exchanger being disposed between the compressor turbines and the compressor units, the exhaust from the gas turbine being directed through the main heat exchanger; (f) an interim heat exchanger being disposed between the compressor units; (g) a first external heat exchanger being disposed downstream of the main heat exchanger; and (h) a second external heat exchanger being disposed between the last compressor turbine and the combustion chamber of the gas turbine; wherein the first and the second external heat exchangers enable a predetermined h/p ratio to be achieved between the thermal power given off in the interim and the external heat exchangers and the mechanical power delivered to the gas turbine.
Claim 3
Dependent Claim
14 words
The plant according to claim 1, wherein an efficiency level of 35% is achieved.
Claim 4
Dependent Claim
19 words
The plant according to claim 1, wherein the plant operates in the region of between 50 and 3000 kW.
Claim 5
Dependent Claim
54 words
The plant according to claim 1, further comprising an injector disposed in the combustion chamber, the injector being in fluid connection with a water storage tank, the water storage tank being connected between the compressor units on the cooling side of the interim heat exchanger to further reduce the emission of NO x .
Claim 6
Dependent Claim
22 words
The plant according to claim 1, further comprising: (i) means for raising the temperature of the fluid stream of the compressor turbines.
