| 摘要 |
<p>The invention consists in a method of modifying a steam turbine (1), steam being generated by a steam generator, the method enabling the turbine (1) to be adapted to the change from a first maximum thermal power of the steam generator to a second maximum thermal power of the steam generator, the turbine (1) including a high-pressure module (2) comprising at least one set (2A) of fixed blades and a rotor (4) supporting at least one set (2B) of moving blades, characterised in that the method comprises the replacement, in the high-pressure module (2), of at least one set (2A) of fixed blades sized for the first maximum thermal power by at least one set (2A) of fixed blades sized for the second maximum thermal power, and in that the set or sets (2B) of moving blades being sized to operate at the first and second maximum thermal powers, the rotor (4) and the set or sets (2B) of moving blades of the high-pressure module (2) remain unchanged on changing from the first maximum thermal power to the second maximum thermal power.</p> |
