Abstract
The method and system are for implementing the method so as to alleviate the disadvantages of a reciprocating combustion engine and gas turbine when generating power. A combustion chamber is arranged outside a turbine and provides compressed air from a turbocharger powered with a heat source in order to carry out a combustion process supplemented with high pressure steam pulses.
Claims19
A power generating system comprising:
- a turbine in connection with one or more compressors for converting energy fed to the turbine into mechanical energy of a rotatable power shaft and to compress air with the one or more compressors,
- a combustion chamber arranged to receive a fuel from a fuel tank and a compressed air to initiate a cyclic combustion process comprising a compression phase and an expansion phase and to output combustion products into the turbine for rotating a rotor of the turbine and thereby rotating the power shaft,
- one or more fuel input valves for providing the fuel to the combustion chamber,
- one or more air input valves for providing the compressed air to the combustion chamber,
- a control unit for controlling said one or more fuel input valves and the one or more air input valves in order to control the combustion process, and
- a turbocharger for compressing air for the combustion process, and means for powering said turbocharger using a heat source and a circulation of fluid heated with said heat source for powering said turbocharger with said circulation of fluid
- wherein the system comprises multiple air chambers having means for heating air inside the air chambers, wherein each of said multiple air chambers are configured to receive a compressed air from the turbocharger, heat the compressed air from the turbocharger, and exhaust a heated compressed air to the combustion chamber.

A method for generating power comprising:
- a step of providing an input of compressed air to a combustion chamber,
- a step of providing an input of fuel to the combustion chamber,
- a step of providing an output of a stream of combustion products and compressed air from the combustion chamber to a turbine for producing power,
- a step of operating one or more compressors for compressing air for the combustion chamber,
- a step of controlling the input of compressed air and the input of fuel to the combustion chamber for running a cyclic combustion process comprising a compression phase and an expansion phase in the combustion chamber, wherein said step of controlling the input of compressed air and the input of fuel is time-dependent,
- a step of extracting a heat from a heat source,
- a step of generating a high pressure gas by heating a liquid with said heat extracted from the heat source,
- a step of operating a turbocharger with said high pressure gas to compress air,
- a step of exhausting compressed air from the turbocharger into the combustion chamber for achieving a first pressure level, and exhausting compressed air from the one or more compressors into the combustion chamber for increasing pressure inside the combustion chamber from the first pressure level to a second pressure level, higher than the first pressure level, and
- a step of accumulating compressed air from the one or more compressors to multiple air chambers, heating compressed air inside the multiple air chambers creating a heated compressed air, and exhausting the heated compressed air from the multiple air chambers into the combustion chamber.
