FIELD: machine building.SUBSTANCE: invention consists in the method for readjusting a steam turbine (1) with the steam for it being produced by a steam generator. The method allows for the adjustment of a turbine (1) to pass from the first maximum of steam generator heat output to the second maximum of steam generator heat output. The turbine (1) comprises a high-pressure module (2) including at least one set (2A) of stationary blades and at least one set (2B) of moving blades set on a rotor (4). The method implies that in the high-pressure module (2) at least one set (2A) of stationary blades designed to be operated under the conditions of the first heat output maximum is replaced by at least one set (2A) of stationary blades designed to be operated under the conditions of the second heat output maximum. The set or sets (2B) of moving blades are designed to be operated under the conditions of the first or second heat output maximum, the rotor (4) and the set or sets (2B) of moving blades of the high-pressure module (2) remain unchanged at the transition from the first maximum of steam generator heat output to the second maximum of steam generator heat output.EFFECT: method makes it possible to avoid the rotor replacement at readjustment keeping acceptable efficiency for two maximums of heat output.8 cl, 5 dwg |
