A cogeneration method and device by turbine, particularly by gas turbine, uses a compression section, at least one expansion section, and a combustion chamber. A combustion agent including oxygen is compressed in the compression section; in the combustion chamber, one combustion step is carried out under pressure with a mixture of combustion agent compressed with a fuel; at least some of the hot gases obtained by pressurized combustion are used to effect an exchange with an external facility; and at least one postcombustion step is carried out of a mixture of hot gases coming from combustion with a fuel, prior to the exchange, and at least one other postcombustion step of a mixture of hot gases, coming from the exchange, with a fuel, in order to obtain hot gases that are sent to the expansion section.
