Blade for the last stage of the steam turbine of the nuclear power and low-pressure steam turbine included this blade

摘要

The blade for the last stage of the steam turbine of the nuclear power plant includes a heel and a heel opposite tip, its height being 840 mm, defined as the heel to tip distance, is adapted for the heel diameter of the rotor disk 1540 mm - 1750 mm to form the outlet steam surface of the size 6.28 m2 – 6.84 m2. The blade shape is characterized by at least a heel profile A defined in the blade heel, a central profile B defined at a height of 420 mm from the blade heel and a tip C profile defined at a height of 840 mm from the heel blade. All the profiles are described by a set of parameters.
