Patent ID: 8621872

Claim:
A method for converting thermal energy from carbonaceous raw materials into mechanical work using at least a first device and a second device for storing and releasing thermal energy, the first device and the second device being connected to a turbine line of a downstream gas turbine, said method comprising the following steps: a) combustion of a gas in a gas burner, b) conveyance of the flue gases formed in the gas burner through at least one of the first device and the second device for storing thermal energy, c) compression of the air fed to the first device and/or the second device for storing thermal energy, and d) introduction of compressed hot air released by at least one of the first device and the second device into the gas turbine, wherein in a first step, the carbonaceous raw materials are gasified in a gasifier, the product gas is fed to the gas burner downstream of the gasifier, and there is no direct gas connection between the gas turbine and the gasifier.
