Abstract

Abstract The invention relates to a system for power generation comprising a turbine system and a power generating system connected to said turbine system, wherein the said turbine system comprises: a) a compressor means (22) provided with an inlet for oxygen-containing gas, an outlet for compressed oxygen-containing gas and inlet means (38) for supplying fluid to said compressor means for cooling the said oxygen-containing gas; b) a combustion means (11) provided with a non-gaseous fuel inlet and a flue gas outlet, said combustion means being connected with the said outlet for compressed oxygen-containing gas of the said compressor means; c) a gas turbine means (9) connected with said flue gas outlet of the said combustion means and being provided with an outlet for exhaust gases; d) a recuperator means (17) connected with 1 the said outlet for compressed oxygen-containing gas of the said compressor means and 2 the said outlet for exhaust gases of the said gas turbine means, for mutual heat exchange.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 153 words
A system for power generation comprising a turbine system and a power generating system connected to said turbine system, wherein the said turbine system comprises: a) a compressor means connected with an inlet for oxygen-containing gas, an outlet for compressed oxygen-containing gas and inlet means for supplying fluid to said compressor means for cooling the said oxygen-containing gas; b) a combustion means provided with a non-gaseous fuel inlet and a flue gas outlet, said combustion means being connected with the said outlet for compressed oxygen-containing gas of the said compressor means; c) a gas turbine means connected with said flue gas outlet of the said combustion means and being provided with an outlet for exhaust gases; d) a recuperator means connected with 1 the said outlet for compressed oxygen-containing gas of the said compressor means and 2 the said outlet for exhaust gases of the said gas turbine means, for mutual heat exchange;
Claim 2
Dependent Claim 34 words
The system as claimed in claim 1 wherein said fluid is directly supplied to the oxygen-containing gas in and/or after the compressor means and the cooling is essentially obtained by evaporation of said fluid.
Claim 3
Independent Claim 29 words
The system as claimed in any of claims 1-2, wherein the said exhaust gases from the said gas turbine means are expanded to a sub-atmospheric pressure of 0.2-0.8 bara.
Claim 4
Independent Claim 26 words
The system as claimed in any of the claims 1-3, wherein the exhaust gases leaving the gas turbine system are cooled and water is condensed out.
Claim 5
Independent Claim 36 words
The system as claimed in any of the claims 1-4, wherein at least part of the exhaust gas from said gas turbine means is recycled to the said inlet for oxygen-containing gas of said compressor means.
Claim 6
Independent Claim 34 words
The system as claimed in any of the claims 1-5, wherein the fuel is dried in a dryer for which the heat required is taken from the exhaust gas from the gas turbine means.
Claim 7
Independent Claim 18 words
The system as claimed in any of the claims 1-6, wherein the non-gaseous fuel is an organic material.
Claim 8
Independent Claim 24 words
The system as claimed in any of the claims 1-7, wherein the flue gas outlet of the combustion passes through a gas cleaning unit.
Claim 9
Independent Claim 17 words
The system as claimed in any of the claims 1-8, wherein the gas is cleaned during combustion.
Claim 10
Independent Claim 22 words
The system as claimed in any of the claims 1-9, wherein the exhaust gases are cleaned after leaving the gas turbine means.
Claim 11
Independent Claim 22 words
The system as claimed in any of the claims 1-10, wherein the exhaust gases which are routed to the stack are cleaned.
Claim 12
Independent Claim 26 words
The system as claimed in any of the claims 1-11, wherein part of the heat developed in the power generating system is applied for heating purposes.
Claim 13
Independent Claim 18 words
The system as claimed in any of the claims 1-12, wherein condensation takes place in two consecutive steps.
Claim 14
Independent Claim 26 words
The system as claimed in any of the claims 1-13, wherein the inlet means for fluid comprise means for atomizing said fluid in the oxygen-containing gas.
Claim 15
Dependent Claim 37 words
The system as claimed in claim 14, wherein fluid is atomized in an amount of up to 12-15% by weight in the oxygen containing gas in the form of droplets having a size of about 1-5 µm.
