Steam Turbine Parson

Steam turbine Parson is steam turbine which has working principle of reaction with axial flow. Steam turbine Parson is generally terraced for large capacity and low rotation. Steam expand both on the steering blade and motion blade so direct push on the blade in the axial direction.

Although conversion energy occur both on steering blade and motion blade, steam turbine produce tangential power only in motion blades. Furthermore steam turbine Parson can be called also as steam turbine semi reaction.

The advantage of steam turbine Parson is better efficiency than steam turbine Zoelly. The disadvantageous of steam turbine Parson are regulatory system is more complicated, construction cost is more expensive when compared with steam turbine De Laval, steam turbine Curtis and steam turbine Zoelly.
