PRODUCT INFORMATION
HYDRO TURBINES:-
1. HYDROELECTRIC POWER PLANT:
The purpose of a hydro-electric power plant is to harness power from
water. As such it incorporates a no. of water driven prime movers
known as water turbines. The water or hydraulic Turbine converts the
kinetic and potential energies possessed by water into mechanical
power. The hydraulic turbine when coupled to a generator produces
electric power.
2. Advantages of hydraulic electric power:
a. Cheap and immune to inflation
b. inexhaustible
c. This can be developed wherever water continuously flowing under
pressure.
d. robust, reliable, lest maintenance.
e. Operate in high efficiencylevel.
f. Quick loading and off-loading flexibilities.
g. Idealpeaking partner of base load thermal/nuclear.
h. Multipurpose benefits
i. No pollution to environment.
22. 3. INTRODUCTION:
Hydraulic turbines are highest efficiencyprime movers used for
power productionwhich utilize the energy of water ways. The
hydraulic energy contained in the stream is converted by to mechanical
power.
Basically these are of two types:
a. Impulse turbines
b. Reaction turbines
In an impulse turbine the water possessing kinetic energy is supplied to
the runner at Atmospheric pressure.The flow through the runner is entirely
at atmospheric pressure,the force exerted by the water being due to the
impulse of the jet.
In a reaction turbine the water supplied to the runner possesses energy
which is partly kinetic and partly pressure.Both types of energies are
converted into work in the runner which results in a drop of pressure and
absolute velocity of water.
23. FURTHER CLASSIFICATIONOF IMPULSE AND REACTION
TURBINES:
Impulse turbine:
- pelton turbine
Reaction turbine:
- Francis turbine
- Kaplan and Propellerturbine
Propellerturbines are mainly Kaplan turbines but Moody, nagler and
Bell turbines may be found in market. The main difference between
Kaplan and other type of propellerturbines is that the formerhas
adjusted runner blades.
FRANCIS TURBINE-
These are inward flow reaction turbine.
Used when operating head is in the range of 30-500m.
These are medium pressure turbine.
Total machines -190
Megawatt capacity-5-165 MW
Runner radius-1050-5250mm
24. FRANCIS TURBINES
The Francis turbine is a type of water turbine that was developed by James B.
Francis in Lowell, Massachusetts. It is an inward-flow reaction turbine that combines
radial and axial flow concepts.
The Francis turbine is a reaction turbine, which means that the working fluid changes
pressure as it moves through the turbine, giving up its energy. A casement is needed to
contain the water flow. The turbine is located between the high-pressure water source
and the low-pressure water exit, usually at the base of a dam.
The inlet is spiral shaped. Guide vanes direct the water tangentially to the turbine wheel,
known as a runner. This radial flow acts on the runner's vanes, causing the runner to
spin. The guide vanes (or wicket gate) may be adjustable to allow efficient turbine
operation for a range of water flow conditions.
25. As the water moves through the runner, it’s spinning radius decreases,
further acting on the runner. For an analogy, imagine swinging a ball on a
string around in a circle; if the string is pulled short, the ball spins faster due
to the conservation of angular momentum. This property,in addition to the
water's pressure,helps Francis and other inward-flow turbines harness
water energy efficiently.
At the exit, water acts on cup-shaped runner features, leaving with no swirl
and very little kinetic or potential energy. The turbine's exit tube is shaped
to help decelerate the water flow and recover the pressure.
26. MAIN COMPONENTS OF FRANCIS TURBINE:
1. SPIRAL CASING: in order to distribute the water around the guide
ring evenly the scrollcasing is designed with a cross sectional
area reducing uniformly around the circumference,maximum at
the entrance and nearly zero at tip. This gives spiral shape and
hence is named as spiral casing. These are also provided with
inspectionholes and also with pressure gauge connection.
2. GUIDE MECHANISM: these have a cross sectional area of aero
foil section. This particular cross sectionallows water to pass over
them without forming eddies and with minimum frictional losses.It
is mounted on a ring which is connected to generator shaft by
means of a regulating shaft depending upon load, speed of turbine
is controlled by a governor which basically deals with the guide
vane opening.
3. DRAFT TUBE: It is a conduit which connects the runner exit to the
Tail race. A tube should be drowned approx. below the lowest tail
race level. It basically increases the workable head of turbine by
an amount equal to the height of the runner outlet, thus making it
possibleto install the turbine above the tail race level without loss
of head.
APPLICATION OF FRANCIS TURBINES
Francis turbines may be designed fora wide range of heads and flows.
This, along with their high efficiency,has made them the most widely used
turbine in the world. Francis type units cover a head range from 20 to
700 meters, and their output power varies from just a few kilowatts up to
one Giga watt. Large Francis turbines are individually designed foreach
site to operate at the highest possible efficiency,typically over 90%.
In addition to electrical production, they may also be used for pumped
storage, where a reservoir is filled by the turbine (acting as a pump) during
low power demand, and then reversed and used to generate power during
peak demand.

PELTON TURBINE
These are impulse turbines which extract energy from the
impulse (momentum) of moving water.
These are high pressure turbines
Total machines-46
Head limit-245-1025m
Megawatt limit-1.5-200 MW
28. The Pelton wheel is an impulse turbine which is among the most efficient
types of water turbines. It was invented by LesterAllan Pelton in the 1870s.
The Pelton wheel extracts energy from the impulse (momentum) of moving
water, as opposed to its weight like traditional overshot water
wheel. Pelton's paddle geometrywas designed so that when the rim runs
at ½ the speed of the water jet, the water leaves the wheel with very little
speed,extracting almost all of its energy, and allowing for a very efficient
turbine.
The water flows along the tangent to the path of the runner. Nozzles direct
forcefulstreams of water against a series of spoon-shaped buckets
mounted around the edge of a wheel. As water flows into the bucket, the
direction of the water velocity changes to follow the contour of the bucket.
When the water-jet contacts the bucket, the water exerts pressure on the
bucket and the water is decelerated as it does a "U-turn" and flows out the
other side of the bucket at low velocity. In the process,the water's
29. momentum is transferred to the turbine. This "impulse" does work on the
turbine. For maximum power and efficiency,the turbine system is designed
such that the water-jet velocity is twice the velocity of the bucket. A very
small percentage of the water's original kinetic energy will still remain in the
water; however, this allows the bucket to be emptied at the same rate it is
filled, (see conservation of mass), thus allowing the water flow to continue
uninterrupted. Often two buckets are mounted side-by-side,thus splitting
the water jet in half (see photo). This balances the side-load forces on the
wheel, and helps to ensure smooth, efficientmomentum transfer of the fluid
jet to the turbine wheel.
Because water and most liquids are nearly incompressible,almostall of the
available energy is extracted in the first stage of the hydraulic turbine.
Therefore,Peltonwheels have only one turbine stage, unlike gas turbines
that operate with compressiblefluid.
PARTS OF PELTONTURBINE:
1. Guide mechanism: this mechanism controls the quality of water
passing through the nozzle and striking the bucket thus meeting
the variable demand of power. It maintains the speed constant of
wheel, when head varies.
2. Bucketand runner: Each bucket is divided vertically into two
parts by splitter, which is the sharp edge at center giving the
shape of double hemispherical cup (in BHEL, the edge of splitter is
cut to increase efficiencyand to reduce the impact force of the
impinging jet which otherwise will decrease the life of bucket).
3. Casing: itdoes not have any hydraulic function to perform.It is
necessaryonly to prevent splashing and to lead the water to tail
race, and also further safe guard against accidents.
4. Hydraulic brakes: Aftershutting down the inlet valve of turbine,
the large capacity of runner will go on revolving or a considerable
period,due to inertia. This has necessitated the developmentof
brakes to bring the turbine to a standstill in a shortestpossible
time.
30. APPLICATION OF PELTON WHEEL
Pelton wheels are the preferred turbine for hydro-power, when the available
water source has relatively high hydraulic head at low flow rates. Pelton
wheels are made in all sizes. There exist multi-ton Pelton wheels mounted
on vertical oil pad bearings in hydroelectric plants. The largest units can be
up to 200 megawatts. The smallest Pelton wheels are only a few inches
across,and can be used to tap power from mountain streams having flows
of a few gallons per minute. Some of these systems utilize
household plumbing fixtures for water delivery. These small units are
recommended foruse with thirty meters or more of head, in order to
generate significant power levels. Depending on water flow and design,
Pelton wheels operate bestwith heads from 15 meters to 1,800 meters,
although there is no theoretical limit.
The Pelton wheel is most efficientin high head applications (see the
"DesignRules" section).Thus, more power can be extracted from a water
source with high-pressure and low-flow than from a source with low-
pressure and high-flow, even when the two flows theoretically contain the
same power. Also a comparable amount of pipe material is required for
each of the two sources,one requiring a long thin pipe, and the other a
short wide pipe.
KAPLAN TURBINE-
The Kaplan turbine is a propeller-type water turbine which has
adjustable blades.
These are reaction turbines
The head ranges from 10-70 meters
Output from 5 to 120 MW
Runner diameters are between 2 and 8 meters

31. The Kaplan turbine is a propeller-type water turbine which has adjustable
blades.It was developed in 1913 by the Austrian professor Viktor Kaplan,
who combined automatically adjusted propellerblades with automatically
adjusted wicket gates to achieve efficiencyover a wide range of flow
and water level.
Its invention allowed efficientpower production in low-head applications
that was not possible with Francis turbines. The head ranges from 10-70
meters and the output from 5 to 120 MW. Runner diameters are between 2
and 8 meters.The range of the turbine is from 79 to 429 rpm. Kaplan
32. turbines are now widely used throughout the world in high-flow, low-head
power production.
THEORY OF OPERATION
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. The designcombines features of
radial and axial turbines.
The inlet is a scroll-shaped tube that wraps around the turbine's wicket
gate. Water is directed tangentially through the wicket gate and spirals on
to a propellershaped runner, causing it to spin.
The outlet is a specially shaped draft tube that helps decelerate the water
and recover kinetic energy.
The turbine does not need to be at the lowest point of water flow as long as
the draft tube remains full of water. A higher turbine location, however,
increases the suction that is imparted on the turbine blades by the draft
tube. The resulting pressure drop may lead to cavitation.
APPLICATION OF KAPLAN
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.
HYDRO TURBINE GOVERNOR
Used to govern the speed of rotation of the runner such that the
frequencyof power generated is 50 Hz.
This is done by controlling the opening of guide vanes.

34. CONSTRUCTION OF RUNNER HUB AND BLADE
The runner blades are operated to smoothly adjust their blade angles by a
link mechanism. Their mechanism is installed inside the runner hub,
containing the runner blade and stem, the link crosshead and so on. A high
quality lubricating oil is filled inside the runner hub to lubricate the
mechanism interior.

MAIN SHAFT
The main shaft for the turbine is made of high-grade forged carbonsteel.
When the size of the main shaft exceeds the limitation of forging capacity
or transportation or it is economical,the main shaft is formed by welding
steel plates or a combination of forged steel and steelplates.
The main shaft is connected to the generator shaft or the intermediate shaft
by a flange coupling. The shaft surface passing through the shaft seal is
protected with a stainless steel shaft sleeve to prevent the main shaft
from wearing.

35. Power of Water Turbine
The power available in a stream of water is;
where:
P = power (J/s or watts)
η = turbine efficiency
ρ = density of water (kg/m³)
g = acceleration of gravity (9.81 m/s²)
h = head (m). For still water, this is the difference in height between the inlet and outlet surfaces.
Moving water has an additional component added to account for the kinetic energy of the flow.
The total head equals the pressure head plus velocity head.
= flow rate (m³/s)
DESIGN AND APPLICATION
Turbine selectionis based mostly on the available water head, and less so
on the available flow rate. In general, impulse turbines are used for high
head sites, and reaction turbines are used for low head sites. Kaplan
turbines with adjustable blade pitch are well-adapted to wide ranges of flow
or head conditions,since their peak efficiencycan be achieved over a wide
range of flow conditions.
36. Small turbines (mostly fewer than 10 MW) may have horizontal shafts and
even fairly large bulb-type turbines up to 100 MW or so may be horizontal.
Very large Francis and Kaplan machines usually have vertical shafts
because this makes best use of the available head, and makes installation
of a generator more economical.Pelton wheels may be either vertical or
horizontal shaft machines because the size of the machine is so much less
than the available head. Some impulse turbines use multiple water jets per
runner to increase specificspeedand balance shaft thrust.

Specific speed
The specific speed ns of a turbine characterize the turbine's shape in a way
that is not related to its size. This allows a new turbine designto be scaled
from an existing designof known performance.The specificspeedis also
the main criteria for matching a specific hydro site with the correctturbine
type.
The specific speed is the speed with which the turbine turns for a particular
discharge Q, with unit head and thereby is able to produce unit power.
Affinity laws
Affinity Laws allow the output of a turbine to be predicted based on model
tests. A miniature replica of a proposed design, about one foot(0.3 m) in
diameter, can be tested and the laboratory measurements applied to the
final application with high confidence.Affinity laws are derived by requiring
similitude between the test modeland the application. Flow through the
turbine is controlled either by a large valve or by wicket gates arranged
around the outside of the turbine runner. Differential head and flow can be
plotted for a number of differentvalues of gate opening, producing a hill
diagram used to show the efficiencyof the turbine at varying conditions.
37. Runaway speed
The runawayspeedof a water turbine is its speed atfull flow, and no shaft
load. The turbine will be designed to survive the mechanical forces of this
speed.The manufacturer will supply the runaway speed rating.

38. CONLUSION
The Vocational training at BHEL Bhopal helped me in
improving my practical knowledge and understanding of
Hydro turbine, its manufacturing and types to a large
extent. Here I came to know about the technology and
material used in manufacturing of hydro turbine. Besides
this, I also visualized the parts involved and equipment
that were used during the manufacturing process of these
turbines. In all it was a truly learning experience for me. As
a mechanical engineering student I hope that the training I
got here would help me in coming future. I hereby thank all
the authorities at BHEL for their kind cooperation and
guidance.
