Abstract
An off-shore power plant in which the steam generators of the power plant are located within the support structure carrying the components of the power plant. The steam generator is operated with superpressure in the combustion chamber. A gas turbine is connected to the flue gas smoke stack of the combustion chamber, and a steam turbine is connected to the steam duct of the chamber. The support structure holding the steam generator carries a platform with several decks. The water treatment and gas purification equipment is located on the lower deck, whereas the upper deck carries the turbines and the generators.
Claims9
An off-shore power plant comprising, in combination, support means for carrying the components of said power plant, and having hollow interior chamber means, steam generator means in said support means;
- combustion chamber means within said interior chamber means of said support means and having flue gas smokestack means and steam duct means, said combustion chamber means being connected to said steam generator means and operated at superpressure;
- gas turbine means connected to said flue gas smokestack means;
- steam turbine means connected to said steam duct means;
- platform means carried by said support means and having a plurality of decks, said gas turbine and said steam turbine means being located on one of said decks.
The off-shore power plant as defined in claim 11 including water treatment and gas purification means on a lower one of said decks, the upper one of said decks carrying said turbine means and said steam generator means.
The off-shore power plant as defined in claim 11 including water treatment and gas purification means carried by a lower one of said decks, the upper one of said decks carrying said turbine means and said steam generator means;
- cover means for covering an opening communicating with said turbine means and said generator means from above, said turbine means and said generator means being accessible from above through said opening;
- flashing turbine means operable by natural gas at well pressure;
- compressor means connected to said flashing turbine means for compressing the air for combustion, said decks being floatable;
- support leg means connected to said decks, said support leg means being lowerable and floatable;
- said support means having a plurality of supporting legs with hollow interior chamber means for holding said combustion chamber means;
- said combustion chamber means having super-charged boilers of cylindrical shape adapted to be held in said support legs, said gas turbine means and steam turbine means cooperating in a gas-steam process having substantially increased power output per unit area, said power plant being substantially assembable on-shore and towable to an off-shore location.
