Features of the steam turbine

Adoption of a reaction turbine

In a reaction turbine, in addition to receiving the impulse of steam ejected from the stationary blades, together with the reaction force of steam ejected from the moving blades, the reaction blade cascade that rotates the rotor has a steam flow velocity that is slower with respect to the impulse blade cascade, and because the flow direction change in the moving blades is small, the efficiency of the turbine is high.

Integral shroud blades

A highly reliable integral machined structure is adopted which includes the shroud section.

Double casing structure

A structure is adopted that can reduce thermal stress and thermal deformation by separating the casing inside and outside.

Low pressure impeller

A free-standing low pressure impeller is adopted which does not use a shroud or lacing wires.
