What type of turbine is Kaplan?
Kaplan turbine is a complete reaction turbine that works based on the lift force generated on the impeller blades due to its aerofoil shape .
What is the other name of Kaplan turbine?
In 1913, an Austrian professor Viktor Kaplan who developed this turbine combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level. It is also called as propeller turbine and evolved from the Francis Turbine.
How much is a Kaplan turbine?
The maximum specific cost of installation among the examined Kaplan projects is $1,029/kW, while the minimum value is $280/kW and the mean value found among the plants examined is $574/kW. 4,900MW.
What is the most efficient hydro turbine?
Pelton wheel, which is an impulse type turbine invented by an American engineer L. Pelton in the 19th century and has proven to be among the most efficient hydroturbines.
Who invented Kaplan turbine?
Viktor KaplanKaplan turbine / Inventor
What is the difference between Francis and Kaplan turbines?
General differences between Francis and Kaplan turbines Kaplan turbine is more compact in cross-section and has lower rotational speed to that of Francis turbine. In Kaplan turbine, the water flows axially in and axially out while in Francis turbine it is radially in and axially out.
How does a Kaplan turbine work?
The Kaplan turbine is an inward flow reaction turbine, which means that the working fluid changes pressure as it moves through the turbine and gives up its energy. Power is recovered from both the hydrostatic head and from the kinetic energy of the flowing water.
What are four types of turbines?
While turbines can be classed as either impulse or reaction according to the way they function, there are four broad types of turbines categorized according to the fluid that supplies the driving force: steam, gas, water, or wind.
How many blades are in Kaplan turbine?
Kaplan Turbine has a very small number of blades 3 to 8.
Where are Kaplan turbines used?
Kaplan turbines are widely used throughout the world for electrical power production. They cover the lowest head hydro sites and are especially suited for high flow conditions.
