What are the classification of turbines?

The main classification depends upon the type of action of the water on the turbine. These are (i) Impulse turbine (ii) Reaction Turbine. Most of the electrical generators are powered by turbines.

What is the different classification of reaction turbine?

Reaction based turbines include three subtypes: Francis turbine, propeller turbine (bulb turbine, Straflo turbine, Kaplan turbine types), and kinetic turbine.

What are the four basic classifications of turbines?

There are, as noted above, four major kinds of reaction turbines in wide use: the Kaplan, Francis, Deriaz, and propeller type. In fixed-blade propeller and adjustable-blade Kaplan turbines (named after the Austrian inventor Victor Kaplan), there is essentially an axial flow through the machine.

Why is it categorized as impulse turbine?

Impulse turbines are defined as turbines in which high-velocity jets of water or steam collide with the blades of the turbine to rotates the turbine and produce electricity using this winding. The impulse turbine is so named because it acts on the impulse force created for the striking blade of the water jet.

What is impulse turbine give example?

Impulse Turbine: If at the inlet of the turbine, the energy available is only kinetic energy, the turbine is known as impulse turbine. Example: Pelton wheel turbine.

Which of the following is an impulse turbine example?

Which of the following is an example of impulse turbine? Explanation: Pelton Wheel Turbine is an example of impulse Turbine.

What is impulse turbine example?

Example: Pelton wheel turbine. Pelton Wheel Turbine: It is a tangential flow impulse turbine in which the pressure energy of water is converted into kinetic energy to form a high-speed water jet and this jet strikes the wheel tangentially to make it rotate.

What is the principle of impulse turbine?

Impulse turbine work on the principle of Newton’s second law as the resulting change in momentum sets buckets and wheel into rotary motion and thus mechanical energy is made available at the turbine shaft. The fluid jet leaves the runner with a reduced energy.

Where are impulse turbines used?

Impulse turbines are most efficient for use in cases where the flow is low and the inlet pressure is high. Reaction turbines develop torque by reacting to the gas or fluid’s pressure or mass. The pressure of the gas or fluid changes as it passes through the turbine rotor blades.
