An intercooler ( 3 ) is provided with heat exchanger surfaces ( 6 ) and is arranged in the gas stream between two compressors ( 1, 2 ) or two compressor stage groups for compressing a gas. An aftercooler ( 5 ) is also provided with heat exchanger surfaces ( 7 ) and is arranged after the second compressor ( 2 ). To utilize the waste heat generated in the coolers ( 3, 5 ), the heat exchanger surfaces ( 6, 7 ) of the intercooler ( 3 ) and of the aftercooler ( 5 ) are integrated in a steam generator ( 9 ) in such a way that the heat exchanger surfaces are connected with the feedwater pump ( 40, 59 ) of the steam generator ( 9 ).
