Difference Between Impulse Turbine and Reaction Turbine

As I all mention in my previous article about impulse turbine and reaction turbine, now in this article i will tell you all about difference  between Impulse turbine and Reaction Turbine.

Difference Between Impulse Turbine and Reaction Turbine:

Impulse Turbine        

  1. In impulse turbine steam passed from nozzle and hit with blades.
  2. Steam hits with high velocity with the blades.
  3. When steam hits with blades it's velocity remains constant.
  4. Blades of impulse turbine are symmetrical.
  5. There is a nozzle in impulse turbine.

Reaction turbine

  1. In reaction turbine steam passed from guide vane and hits with the blades.
  2. Steam hits with high pressure with blades and increase the kinetic energy of the blades.
  3. When steam hits with the blades it's velocity remains not constant and decrease.
  4. Blades of reaction turbine are not symmetrical.
  5. There no nozzle but guide vane work as nozzle.

Steam and Gas Turbine In Mechanical Industry

Steam and Gas Turbine:


Steam Turbine is a prime mover in which the moment of the steam changes and get rotatory motion from it. In reciprocating steam engine, steam act on the face of steam piston. In the result of this piston start the reciprocating motion.
There are so many types of turbine that are used in Mechanical industry in different way and also for different work.

Classification of Steam Turbine:

  • According to made of Steam action
  • According to direction of Steam flow
  • According to exhaust condition
  • According to the pressure
  • According to the number of stages
There are the two most used turbines which are mostly used in industry and also used for other work.
  1. Impulse Turbine
  2. Reaction Turbine

Working principle of Impulse Turbine:


In this turbine, Turbine blades moves with the help of steam impulse that's why it's called impulse turbine.

Working principle of Reaction Turbine:


In this turbine, Steam fell on turbine blades at high pressure and in reaction blade start the movement due to specific shape of turbine blades.
