Beschreibung
Zusammenfassung:	A method for converting thermal energy from carbonaceous raw materials into mechanical work using at least a first and a second device for storing and releasing thermal energy. These devices 4, 6 are connected alternately by means of controllable valves 36, 38 at least temporarily, into a turbine branch with a downstream gas turbine. The method comprises the following steps combustion of a gas in a gas burner 1, conveyance of the flue gases formed in the gas burner through at least one of the devices 4,6 for storing thermal energy, compression, by means of a compressor, of the air fed to the devices for storing thermal energy, and introduction of compressed hot air released by at least one device into the gas turbine. The carbonaceous raw materials are gasified in a gasifier 1 to form a product gas that is fed to the gas burner 2 downstream of the gasifier 1. There is no direct gas connection between the gas turbine and the gasifier 1. The method allows the reduction of dust in the flue gases.
