Abstract (en)

[origin: WO2008081483A1] A control device (8) for a gas-turbine plant (1), having a compressor (12), a combustion chamber (14) and a gas turbine (15), is provided with a regulator (18), for regulating quantities regarding the plant (1) in a first operating condition, in which a first fuel having a nominal calorific value is supplied to the combustion chamber (14), and in a second operating condition, in which a second fuel, having a second calorific value lower than the nominal calorific value, is supplied to the combustion chamber (14). The device (8) moreover includes a limiter (19), concurrent with the regulator (18) selectively in the second operating condition, for limiting a compression ratio (ß) of the compressor (12) so that a flowrate (Q-<SUB>TOT</SUB>) evolving in the turbine (15) is lower than a pre-set limit flowrate (Q<SUB>TMAX</SUB>)
