ABSTRACT:
In a method of regulating the rotational speed of a gas turbine during load disconnection, the fuel line (8) of which to the combustion chamber (10) can be controlled via regulating valves (5) and via burner control valves (6), and the combustion chamber of which is operated with premixing burners (11), some of the premixing burners are used as idling premixing burners (11a) and the rest are operated only as main burners. During load disconnection, the main burners are shut off by means of the burner control valve (6), and the idling premixing burners are supplied with fuel via a regulated bypass line (3).
