Whilst this makes the Parsons turbine much longer and heavier, the overall efficiency of a reaction turbine is slightly higher than the equivalent impulse turbine for the same thermal energy conversion.

The boilers were designed to produce superheated steam at at The turbine / generator section had two 3, 000 rpm three stage reaction turbines driving alternators rated at 19 MW continuous.

But in the case of reaction turbines, if the net head is low and if the turbine is installed above the tail race, there can be appreciable loss in available pressure head.
14.
In power turbines like reaction turbines, Kaplan turbines, or Francis turbines, a diffuser tube is installed at the exit of the runner, known as "'draft tube " '.
15.
From 1950 he dedicated himself to the research and development of his most important invention, a rotating motor or reaction turbine which he named the " Turboz�m ", also known as a " criole motor ".
16.
Although the turbine is not a classic 17th-century Baker's centrifugal or reaction turbine wheel it might be a transformed one, since this " Buena Vista Turbine " does not fit within the Baker's description.

In the case of steam turbines, such as would be used for marine applications or for land-based electricity generation, a Parsons type reaction turbine would require approximately double the number of blade rows as a de Laval type impulse turbine, for the same degree of thermal energy conversion.
18.
Superheated steam s greatest value lies in its tremendous internal energy that can be used for kinetic reaction through mechanical expansion against turbine blades and reciprocating pistons, that produces rotary motion of a shaft . The value of superheated steam in these applications is its ability to release tremendous quantities of internal energy yet remain above the condensation temperature of water vapor; at the pressures at which reaction turbines and reciprocating piston engines operate.
