<p>A highly corrosion-resistant fixed blade assembly (20) for a steam turbine, in particular a geothermal impulse turbine, is formed by an array (11) of stator blades (12), supported at their respective longitudinally opposite ends (27, 28) by an outer ring (21) and an inner ring (22). Each blade (12), made with a nickel-based metal alloy, for example, an alloy of the Hastelloy<SUP>®</SUP> family or a similar material, is integrally connected to the rings (21, 22) and is supported by the rings via respective mechanical joints (31, 32) devoid of structural welds, so as to be removable from the rings without breaking the rings.</p> |
