TURGO TURBINE

Types of Hydropower Turbines runner

Classification of Hydro Turbines

Reaction Turbines

•Derive power from pressure drop across turbine
•changes pressure as it moves through the turbine and gives up
its energy
•Totally immersed in water
•Angular & linear motion converted to shaft power
•Propeller, Francis, and Kaplan turbines

Impulse Turbines

•Convert kinetic energy of water jet hitting buckets

•impulse turbines change velocity of a water jet\

•No pressure drop across turbines

•Pelton, Turgo, and crossflow turbines

Introduction

Ø The Turgo impulse turbine was invented by

Eric Crewdson, Managing Director of Gilkes, in 1919 and a

patent was awarded in 1920.

Ø A paper was presented in 1922 at the Institution of

Civil Engineers: Design and Performance of a New

Impulse Water-Turbine (Crewdson, 1922).







The turgo turbine is an impulse water turbine design for medium
head application. Operational turgo turbine achieve efficiency of
about 87% . In factory and lab tested turgo turbine performs with
efficiency of about 90%.
q Turgo has some advantages over Francis and Pelton designs for
certain applications.
qTurgos operate in a head range where the Francis and Pelton
overlap. While many large Turgo installations exist, they are also
popular for small hydro where low cost is very important.
qLike all turbines with nozzles, blockage by  debris must be
prevented for effective operation.

Performance envelope

TURGO TURBINE

•Head Range: up to 300m

•Power Output: up to 10MW

APPLICATION

•Turgo Impulse turbines are applicable for medium to high

head applications and overlap the boundary of Pelton and

Francis machines.

•These turbines are well suited to "run of river" schemes as
they can tolerate some "dirty water" and perform well over
wide flow range.
