Combustion turbine system with increased pressure ratio

A method for generating energy from a liquid oxidizer and a liquid or gaseous fuel in a turbo-electric system, wherein the method comprising the steps of:

• providing only liquid oxidizer as an oxidizer in a turbine system for a combustion process, injecting the oxidizer in liquid form from an oxidizer pump directly into a combustion chamber of a turbine:
• pressurizing the oxidizer in liquid form in the oxidizer pump instead of in a compression phase;
• evaporating the oxidizer only in the combustion chamber, then the oxidizer is burned together with the liquid of gaseous fuel, the oxidizer being brought to an injection pressure below the critical temperature of the oxidizer and injected into the combustion chamber;
• expanding combustion gases with a total pressure ratio of 200 or more (π>>200) in the turbine;
• delivering mechanical shaft energy from the turbine to a generator, wherein the generator is capable of being switched to an electric motor operation to drive the turbine in a startup operation;
• converting electrical current from the generator as required;
• and
• passing the electrical current on directly from the generator.
