Method for providing partial load operation in a gas turbine plant

Abstract

Abstract The invention proposes a method for providing partial load operation in a turbine plant. This gas turbine plant essentially comprises a compressor unit (1), an HP combustion chamber (4) arranged downstream of the compressor unit (1), an HP turbine (5) arranged downstream of this HP combustion chamber (4), an LP combustion chamber (8) which is arranged downstream of this HP turbine (5), operates by self ignition and the hot gases of which act on an LP turbine (11). Reducing the quantity of fuel in the LP combustion chamber (8) to zero keeps the temperature at the outlet of the HP turbine (5) essentially constant. During the lowering of the quantity of fuel in the LP combustion chamber (8), the quantity of fuel for the HP combustion chamber (4) furthermore remains approximately constant and the temperature at the inlet to the HP turbine (5) thus likewise remains constant. <IMAGE>
