Abstract
Abstract Plant for the generation by means of a gaseous fluid of mechanical energy comprising an assembly consisting of a gasturbine (1) with a combustion chamber (4) and a compressor unit (C) driven by a turbine (T). This latter turbine (T) is feeded by compressed air from said unit (C) after its passage through a main heat exchanger (3) arranged in the exhaust of the gasturbine (1). The outlet (10) of the compressor-turbine (T) is connected to the combustion chamber (4).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
200 words
Plant for the generation of mechanical energy by means of a gaseous fluid, comprising an assembly made up of a power turbine (1) and a compressor unit (C) driven by at least one individual compressor turbine (T), the inlet of which is connected in series fluid flow relationship to the compressor unit by means of a connecting conduit (6, 8, 9) which is being connected to one heat exchange side of a recuperator (3), the other heat exchange side of said recuperator being connected to the exhaust side of the power turbine for recuperation of heat from the power turbine exhaust gases to the compressed air during operation of the gas turbine plant, characterized in that the heating of the compressed air flowing from the compressor unit (C) to the compressor turbine(s) (T,T1 or T2) takes place in the said recuperator (3), the compressed and heated air expanded in said compressor turbine(s) (T,T1 or T2) being unpolluted, exclusively the gas turbine (1) is provided with a combustion chamber (4) for combustion of fuel in the compressed air, the discharge of the expanded and unpolluted air from the (last) compressor turbine (T or T2) being connected to this combustion chamber (4).
Claim 2
Dependent Claim
41 words
Plant according to Claim 1, in which the compressor unit consists of at least two parts, characterized in that at least one additional heat exchanger (7) is provided in the connecting conduit (6) between the parts (C₁, C₂) of the compressor-unit.
Claim 3
Dependent Claim
21 words
Plant according to Claim 1 or 2, characterized in that the power turbine (1) is designed as a single-flow centripetal turbine.
Claim 4
Dependent Claim
76 words
Plant according to one of the preceding claims, characterized in that in addition to the heat exchanger (7) as the interim cooler in the compressor unit (C) it has at least one other external heat exchanger (17,18) in the exhaust (14) of the gas turbine (1) downstream of the existing recuperator (3), and also in the outgoing conduit (10) of the last compressor turbine (T2) upstream of the combustion chamber (4) of the power turbine (1).
Claim 5
Dependent Claim
59 words
Plant according to any of the Claims 2-4, characterized in that an injector (21) is provided in the combustion chamber (4) said injector being connected to a storage tank (24) for water through a duct (22) and a pump (23), which tank is connected with the portion of the connecting conduit (6) that is cooled in the heat-exchanger (7).
Claim 6
Dependent Claim
45 words
Plant according to any of the Claims 2-5, characterized in that additional means (28,29) are provided in the connecting conduit (8,9) downstream the recuperator (3) for influencing the temperature of the gaseous fluid streaming through this conduit towards the compressor turbine(s) (T or T₁, T₂).
Claim 7
Dependent Claim
87 words
Using the plant according to anyone of the preceding claims by its application to the total energy operation in a greenhouse, characterized in that the pressure and the temperature in the combustion chamber are maintained at a very low level by adapting the supply of clean fuel to the combustion chamber; at the same time involving the necessary external heat exchangers to achieve the predetermined ratio (H/P) between thermal and mechanical power given off, the cooled combustion gases from the power turbine being supplied into the greenhouse.
Claim 8
Dependent Claim
48 words
The use according to claim 7, characterized in that the compressor-unit from the plant is operated such that the pressure within the combustion chamber of the power turbine lies in the order of 200 kPa, the temperature in this combustion chamber being kept in the order of 900°C.
