classification of water turbine

They are used for high-volume commercial sites such as factories and large office complexes, and as control meters for sections of a town or city. Pelton turbine:-A type of impulse water turbine. If N ranges from one to 20, corresponding to high heads and low rotational speeds, impulse turbines are appropriate. CLASSIFICATIONS OF TURBINES:- 1.Steam turbine 2.Gas turbine 3.Transonic turbine 4.Contra Rotating Turbine 5.Ceramic Turbine 6.Shrounded Turbine 7.Bladeless turbine 8.Wind turbine 9.Water Turbine 10. Hydro turbines are devices used in hydroelectric generation plants that transfer the energy from moving water to a rotating shaft to generate electricity.These turbines rotate or spin as a response to water being introduced to their blades. Runner and buckets. Classification of Water Turbines | Electricity 1. The other dams are for recreation, stock/farm ponds, flood control, water supply, and irrigation.

It is an inward-flow reaction turbine that combines radial and axial flow concepts.. Francis turbines are the most common water turbine in use today. CHAPTER – 3 HYDRAULIC TURBINE CLASSIFICATION AND SELECTION 3.1 Introduction (Reaction Turbines) The hydraulic turbine is a mechanical device that converts the potential energy contained in an elevated body of water (a river or reservoir) into rotational mechanical energy. Gorlov Is a water turbine evolved from the Darrieus turbine design by altering it to have helical blades/foils. The type of hydropower turbine selected for a project is based on the height of standing water—referred to as "head"—and the flow, or volume of water, at the site. Pelton Wheel:. •Hydro electric power is the most remarkable development pertaining to the exploitation of water resources throughout the world. Low heads (1 – 5 metres) – though turbines often more appropriate for higher heads Medium flows (0.3 – 1.5 m 3 /s) Francis turbines: No longer commonly used except in very large storage hydropower systems, though lots of older, smaller turbines are in existence and can be restored.

Turbine itself means a thing which rotates or spins. Hydropower plants range in size from small systems for a home or village to large projects producing electricity for utilities. There are different types of hydro power plants based on types of facilities for generation of hydropower. Nozzle of a pelton wheel is a circular guide mechanism which guides the water to flow at the desired directions.It also regulate the ... 2. Type of compounding refers to the use of blading which causes a series of pressure drops, a series of velocity drops, or a combination of the two.Division of steam flow indicates whether the steam flows in just one direction or if it flows in more than one direction. Turbines are also divided by their principle of operation and can be: An Impulse turbine, which is driven by a high-velocity jet (or multiple jets) of water. Classification of Hydraulic turbines: 1) Based on type of energy at inlet to the turbine: Impulse Turbine: The energy is in the form of kinetic form.
