Patent DE-4223528-A1 (DE)
Inventor: SAURER KURT DIPL ING
IPC: F02C7/16
Filed: 1992-07-17
Abstract: The invention pertains to a process for operating a gas turbine as part of a steam process, where the gas turbine has an air compressor (4), a combustor (3) and a turbine (5) which drives the air compressor (4). The object of the invention is to indicate a process whereby a gas turbine can be operated at up to a stoichiometric fuel/air mixture. This is achieved in that the air compressor (4) delivers at least the volume of air required for combustion and the fuel gas is cooled to the permissible turbine entry temperature by being mixed with steam that is taken from an external steam process. Alternatively, the gas turbine also works with interheating between a high-pressure turbine (9) and a low-pressure turbine (10), where the exhaust gas of the high-pressure turbine (9) is heated ahead of the high-pressure turbine (9) by means of heat transfer from the combustor gas, which then cools as a result.
