Method for adding water to a heat exchanging system

Claim 3

A method as in claim 1, wherein said step of compressing includes compressing in at least two steps producing an intermediate compressed medium having waste heat and including the step of transferring said waste heat to said untreated water before saturating and to said pure water before washing.

Claim 4

A method as in claim 1, including the further step of adding the used pure water to said untreated water after washing.

Claim 5

A method as in claim 1, wherein said step of saturating includes the steps of introducing said untreated water into a first contact chamber so that the introduced water falls to the bottom thereof and recirculating water in the bottom of said chamber to region of introduction and including the further step of transferring heat from said exhaust to the recirculating water.

Claim 6

A regenerative gas turbine system comprising: a gas turbine for the production of power; a compressor driven by the gas turbine for compressing a gaseous medium to a predetermined pressure; means for supplying said medium to said compressor; a first contacting chamber for saturating a compressed gaseous medium with steam from untreated water containing impurities to form a mixture of steam and said compressed medium; means for supplying said medium to said first chamber; means for supplying said untreated water to the upper portion of said first chamber; at least two regenerators mounted in series for receiving exhaust gas from the gas turbine; means for recirculating untreated water accumulated in the bottom of the first chamber through one of said regenerators to the top thereof so as to transfer heat to the recirculating water; a second contacting chamber for washing the mixture with pure water to remove said impurities; means for supplying said pure water to the upper portion of said second chamber; means for supplying used pure water accumulated in the bottom of said second chamber to the upper portion of said first chamber; a combustion chamber; means for supplying the washed mixture to said combustion chamber; means for supplying fuel to said combustion chamber for combustion to produce a burned gas discharge; means for supplying said discharge to said turbine; and means for supplying the exhaust gas from said turbine to said regenerators.

Claim 7

A regenerative gas turbine system comprising: a gas turbine for the production of power; a compressor driven by the gas turbine for compressing a gaseous medium to a predetermined pressure; means for supplying said medium to said compressor; a first contacting chamber for saturating a compressed gaseous medium with steam from untreated water containing impurities to form a mixture of steam and said compressed medium; means for supplying said medium to said first chamber; means for supplying said untreated water to the upper portion of said first chamber; at least two regenerators mounted in series for receiving exhaust gas from the gas turbine; means for recirculating untreated water accumulated in the bottom of the first chamber through one of said regenerators to the top thereof so as to transfer heat to the recirculating water; a second contacting chamber for washing the mixture with pure water to remove said impurities; means for supplying said pure water to the upper portion of said second chamber; means for supplying used pure water accumulated in the bottom of said second chamber to the upper portion of said first chamber; a combustion chamber; means for supplying the washed mixture to said combustion chamber; means for supplying fuel to said combustion chamber for combustion to produce a burned gas discharge; means for supplying said discharge to said turbine; and means for supplying the exhaust gas from said turbine to said regenerators.

Claim 8

A system as in claim 5, wherein said recirculating means includes means for discharging said untreated water from the system when it is too dirty.

Claim 9

A system as in claim 5, wherein said compressor is a two stage compressor producing an intermediate compressed medium having waste heat therein and including heat exchange means for transferring said waste heat to said medium and said untreated water before introduction into said first chamber.

Claim 10

A system as in claim 5, further including second means for recirculating said pure water from the top to the bottom of said second chamber through one of said regenerators to transfer heat to the recirculating pure water.
