Abstract: A Stirling engine includes a working cylinder defining a working cylinder chamber with a reciprocatingly-arranged working piston and a heater fluidly communicating with the working cylinder chamber through a working gas channel. The engine includes a first heat exchanger extending from a head of a displacer cylinder into the heater, a second heat exchanger formed by a regenerator arranged outside the heater, and a third heat exchanger formed by a cooler arranged between the regenerator and the working cylinder chamber. At any point along the working gas channel, as seen cross-wise to an assumed working gas flow direction through the working gas channel, the cross section area of the working gas channel defined by the first, second and third heat exchangers is within the range of the medium cross section area of the working gas channel +/?10%.

Abstract: The present invention relates to an indirectly heated gas turbine system comprising a combustion chamber (3) that extends along a central axis of the gas turbine system for the combustion of compressed air and supplied fuel whereby flue gas is formed, a turbine (2) driven by a working medium, a compressor (1) rotatably connected to the turbine for compressing the working medium and/or air to the combustion chamber, and a first heat exchanger device (8) for the transfer of heat between the flue gas and the working medium. The first heat exchanger device and the combustion chamber are integrally formed as a monolithic unit, the first heat exchanger device being substantially arranged within the axial extension of the combustion chamber along the central axis. By the integrated design of the combustion chamber and the first heat exchanger device, a compact, indirectly heated gas turbine system having high efficiency is achieved.
