Method and device of cogeneration by gas turbine with post-combustion chamber

摘要

The process involves compressing an oxidant with a fuel in a compression section (14). The compressed oxidant is combusted under pressure in a combustion chamber (20). A part of hot gas obtained by the combustion is exchanged with an external installation (34). The gas is reheated in an expansion section (52) to obtain hot gas under conditions of temperature and pressure close to those achieved in the absence of gas exchange. An independent claim is also included for a heat and work cogeneration device for use by a gas turbine.
