Disclosed is a gas turbine for transforming thermal energy into mechanical work. The gas turbine comprises a compressor unit and a turbine unit rotating on a common shaft; at least one regenerative, rotatable heat exchanger arranged between an outlet of the compressor unit and an inlet of the turbine unit; and a combustion chamber and associated pipe system. The at least one heat exchanger supplies heat to a first air flow from the compressor unit to the turbine unit by a hot flue gas flow from the combustion chamber, and the gas turbine further comprises a bypass line, bypassing the combustion chamber. The at least one heat exchanger is configured to rotate in a continuous stepless manner and comprises a plurality of parallel, separated duct elements open at both ends, parallel or skewed with the axis of rotation of the at least one heat exchanger and configured to allow a separated two-way flow through the at least one heat exchanger. The by-pass line is arranged between the turbine unit and the at least one heat exchanger, allowing a part of a second air flow from the turbine unit to by-pass the combustion chamber and then to be directed into the at least one heat exchanger and into the hot flue gas flow from the combustion chamber.
