IPC: F01K21/04
Filed: 1992-08-18
Abstract: A process is disclosed for generating energy in a combined gas-steam power station having a gas turbine circuit, in which fresh air is compressed and supplied to a combustion chamber (2) upstream of the gas turbine (3), and a steam turbine circuit with a preferably coal-fired steam generator (6).
