Gas turbine arrangement

A (micro) gas turbine arrangement has a gas turbine device (12) with a combustion chamber system (28), a turbine (30) driven by an exhaust gas stream (32) from the combustion chamber system, and a compressor (22) for supplying the combustion chamber system with a compressed oxidant stream (24), and a recuperator (18) for transmitting at least part of the thermal power of the exhaust gas stream (32) of the turbine (30) to the compressed oxidant stream (24). Also provided are at least one bypass (34, 36) for diverting at least part of the oxidant stream (24) or of the exhaust gas stream (32) around at least one heat exchanger (52) of the recuperator (18) and at least one control element (44, 46) for setting the flow through the at least one bypass (44, 46), in order to be able to adapt the quantity of heat given off by the gas turbine arrangement at the design point and to thus be able to improve the efficiency of a cogeneration system with such a gas turbine arrangement. 本发明涉及种(微型)燃气涡轮结构，其具有燃气涡轮机装置(12)，该燃气涡轮机装
