Method for operating a gas turbine during load control, device for regulating the operation of a gas turbine and power plant

The method involves continuously removing combustion material (B) from a combustion material mesh (13). The combustion material is burned by supplying combustion air into a combustion chamber (46) of a gas turbine (40). Combustion material volume (BV) is removed from a combustion material storage (30) for rapidly increasing combustion material flow supplied to the chamber during starting of the gas turbine, and the material volume is supplied to the combustion material supplied to the chamber. Pressure of the material volume is larger than supply pressure in the material mesh. Independent claims are also included for the following: (1) a device for regulating operation of a gas turbine (2) a power plant comprising a gas turbine.
