Abstract
In a method of operating a gas-turbine group having sequential combustion, action is taken first of all on the inlet temperatures (A, B) at the two turbines (6, 10) in order to provide a partial-load operation. The subsequent lowering of the load takes place by adjustment of the compressor guide blades (C), that is, by reducing the mass flow (E) to below 50% of the rated load (X). During this lowering, the inlet temperature (A) at the first turbine (6) is kept constant, while the other inlet temperature (B) at the second turbine (10) is continuously lowered; the outlet temperature (D) of the second turbine (10) is in contrast kept constant. After the lowering of the load is complete by adjusting the compressor guide blades, the inlet temperatures (A, B) are reduced directly or in a phase-displaced manner (Y).
